Item No. 2 :- Providing & supplying ISI mark CI, S/S pipe of following class and diameter etc complete.

The D.I. pipes shall have mortar lining as per manufacturer's specifications. Jointing the pipes with rubber gasket joints. (viz. Tyton Joints). The tender item covers providing, lowering, laying and jointing of CI/DI pipes as well as CI specials, pipe-pieces, etc., as per requirement and as directed by the Sub-Divisional Officer, by rubber gasket joint viz. Tyton Joints.

The cost of conveyance of these materials from place of the site of work is also included in the Tender item.

Tender rate includes jointing CI/DI pipes with providing rubber gasket made out of S.B.R. and including laying and jointing CI specials with lead joints. The rubber gasket should be of the best quality conforming to IS : 12820. The approved makes - orient rubber Nagpur for rubber gaskets for DI & CI pipes & National rubber co. for rubber gaskets for C.I. pipes. The pipes shall be cut only with mechanical / electrical cutter and the ends after cut shall be chamfered by electric grinder. Cutting with poger and hammer is not permitted.

The method of Tyton joint (i.e. Rubber Gaskets) is as under :

The rubber gasket is inserted in the socket of the pipe which is facilitated by applying a thin film of lubricating oil in such a way that the bulb of


gasket is forward at the back and the socket and the groove in the gasket should be firmly fixed in the projecting ring inside the socket. The gasket has to be properly cleaned before inserting and it has to be ensured that it fits evenly around the whole circumference of the socket, removing any bulges which would prevent the entry of spigot end, then a thin film of lubricant should be applied to the gasket, inside & outside surfaces of entering spigot end for one inch after cleaning it. The pipe to be jointed should be supported centrally by the tackle, so that it is clear of trench bottom. The spigot of the pipe shall be carefully aligned and inserted in the adjoining socket, until it makes contact with the rubber gasket. The spigot shall be forced inside the socket past the gasket (which is thus compressed) until the spigot reaches the end of the socket. The forceful insertion has to be achieved with crowbars, jacks, and lowers, etc. as per the details given in the literature of TISCO or any other suitable method as directed.

However, before lowering of pipes in trenches a layer of murum bedding from the excavated stuff will have to be provided below the pipeline for proper grading and alignment and also to act as cushion and support to pipe.

Certain breakages results during the course of laying and hydraulic testing. These breakages shall be to the account of contractor and no payment on this quantity is admissible for the item of providing of pipes and as well as for the item of lowering, laying of pipes. The final quantity payable under this item shall restricted to the total length laid and successfully tested for that diameter and class of pipes.

Local handling of pipes –

The loading and unloading operation should be done with due care. The local transportation at site is not permissible by rolling the pipes along road and they shall be loaded on hand cart or manually lifted for transportation.

The C.I./D.I. pipes required to be used on the work shall be got inspected by third party. At present the third party agents approved by the Maharashtra Jeevan Pradhikaran are RITES / SGS/ Superintendence and hence the third party inspection shall be carried out through any of these agencies only. Any change in the above names of agencies will be communicated to the contractor and the third party inspection shall have to be carried out, even after awarding the tender, through any one of the changed agencies.

Item No. 3 :- Lowering, laying and jointing C.I. S&S and D.I. pipes –---- etc. complete.

The contractor shall clear the site by removing all greases, shrubs etc. before the start of work. The working longitudinal section of pipeline has to prepare by the contractor in consultation with departmental site Engineer. The Engineer – In – Charge may make modifications in the alignment and or level at his desecration, depending on the site conditions. The contractor shall have to fix the alignment and levels shall be done by the contractor at his cost. Laying underground pipes should be lowered into the trench with tackle suitable for the weight of pipes. For smaller sizes, up to 250-mm nominal bore, the pipe may be lowered by the use of ropes but for heavier pipes, either a well designed set of


178

shear legs or mobile crane should be used. When lifting gear is used, the positioning of the sling to ensure a proper balance should be checked when the pipe is just clear of the ground. If sheathed pipes are being laid, suitable wide slings or scissors dogs should be used.

All construction debris should be cleared from the inside of the pipe either before or just after a joint is made. Passing a pull-through in the pipe, or by hand, depending on the size of the pipe does this. When laying is not in progress, a temporary and closure should be securely fitted to the open end of the pipe line. This may make the pipe buoyant in the event of the trench becoming flooded, in which case the pipes should be held down either by partial re-filling of the trench or by temporary strutting. All persons should vacant any section of trench into which the pipe is being lowered.

On gradients of 1:15 or steeper, precautions should be taken to ensure that the spigot of the pipe being laid does not move into or out of the socket of the laid pipe during the jointing operations. As soon as the joint; assembly has been completed, the pipe should be held firmly in position while the trench is backfilled over the barrel of the pipe. The backfill should be well compacted.

Supporting Pipes above Ground:-

The following recommendations assume that no additional bending moments above those due to the self weight of the pipe and its contents are present.

With spigot and socket pipes-

It is recommended that above ground installations of spigot and socket pipes are provided with one support per pipe, the supports being positioned being the socket of each pipe.

This results in normal distance between supports of 4 m.

Pipes should be fixed to the supports with; mild steel straps so that axial moments due to expansion or contraction resulting from temperature fluctuation, is taken up at individual joints in the pipe line in addition, joints should be assembled with the spigot end withdrawn 5 to 10 mm from the bottom of the socket to accommodate these thermal movements.

Pipes supported in this way are capable of free deflection and axial movement at the joints which accommodate small movements of the pipe supports.

Construction of thrust blocks and anchor blocks shall be done in two stages viz, firstly the position below invert of the pipeline shall be casted and then the portion above pipe be casted. Design of individual thrust block and fixity blocks shall be given by the Engineer-in-charge. The distance between two successive fixity blocks shall generally not exceed 500 m.

Where a pipeline crosses water course, the design and method of construction should take into account the characteristics of the watercourse. The


concerned authorities may be consulted to ascertain the nature of bed, scour levels, maximum velocities, high flood level, seasonal variation, etc. which affect the design and laying of the pipe line. Early consultation with river authorities; will assist in evaluating the effect of river characteristics (for example, nature of bed, scour levels, maximum velocities, high flood levels, seasonal variations, etc.) on design and construction.

If necessary, unsupported spans between 4 and 6 m may; be obtained be positioning the pipe supports relative to the pipe joints.

With flanged pipes-The recommended maximum unsupported span is 8 m. The supports shall be located at the center of every second pipe.

The recommended maximum unsupported span at watercourse is 8m. The relative positions of pipe joints and pipe supports should be stable.

The supports of all flanged pipe work spans should be stable and; unyielding; due to movements in the pipeline.

The straps should prevent any lateral movement or lifting of the pipe lines but now restrict expansions and constructions caused by temperature fluctuations.

Cutting of pipe-

The cutting of pipe for inserting valves, fittings, etc. shall be done in a neat and workman like manner without damage to the pipe or lining so as to leave a smooth; end at right angles to the axis of the pipe. As far as possible at the time of pipe laying, valves & specials should be laid. Due to non availability of valves, specials if the laid pipes should be cut. That case no payment will be given for the work of the pipe cutting and chamfering of pipes to the contractor. Also the cost of cut piece of pipes shall be recovered from contractor. Methods of cutting ductile iron pipes are given in

By Hacksaw-

Hand or power operated hacksaw should be used with blades having teeth at a pitch of 1 mm.

By manually operated wheel cutter-

The type of cutting; wheel used for cast iron pipes is not suitable for ductile iron pipe. Special wheels, as used for cutting steel pipes, shall be used and; cut ends are trimmed with a file.

By pipe cutting machine-

Machines with cutter heads or abrasive wheels shall be used. Cutter head should have a front rake angle of 7 …. As used for steel pipes.


180

The flame cutting of pipes by means of an oxyacetylene torch shall not be allowed.

Permissible Deflection at Socket and Spigot Joints: -

When necessary to deflect pipes from a straight line to avoid obstructions or where long radius curves are permitted, deflections at joint shall not exceed following.

Rubber JointsFor nominal Bore – 80 mm to 300 mm 5 DegreeFor nominal Bore – 350 mm to 450 mm 4 DegreeFor nominal Bore – 450 mm to 750 mm 3 Degree

End preparation of cut pipes for jointing – The barrel left after cutting should be trimmed off by light grinding or by filling.

Wrapping-

when ductile iron pipes are to be laid in aggressive soils; the pipes should be wrapped externally with protective coatings. , such as bitumen or coal tar sheathing protective tapes or by loose polythene slaving, or in certain; circumstances, concrete before laying. At joints, bends and valves, precautions should be taken to provide sufficient overlap of the wrapping sleeve so that no pipe line is exposed to the aggressive soil.

Pipe line markers-

Distinctive markers should be erected at all roads, railways, river and canal crossings, and elsewhere as required to identify the pipe line and to indicate its position. Markers should be placed at field boundaries, preferably; in such a way that they are not obscured by vegetation. At all valve installations, plates should be provided to give the same information as on the makers. Markers should not be treated with any substance likely to be harmful to live stock.

Pipe line Anchorage-

All pipe lines having, unanchored flexible joints require anchorage at changes of direction and at dead ends to resist the static thrusts developed by internal pressure. Dynamic thrusts caused by flowing water act in the same direction as static thrusts. This thrust is of sufficient magnitude at high; velocities; to warrant safety consideration.

Anchorage’s to resist the thrust should be designed taking into account the maximum pressure the main is to carry in service or on test, and the safe bearing pressure of the surrounding soil.

Where possible concrete anchor blocks should be of such a shape as to allow sufficient space for the remaking of the joints.


Laying Procedure: -

Laying of DI pipes shall be done as per I.S. 12288/1987 and as amended from time to time. Rubber gaskets (SBR rings) are to be provided. SBR gasket shall conform to IS 12820/1989 or latest edition.

The jointing operations of mechanical joint shall be done as per instructions given in the literature of the firm manufacturing the mechanical joint. This operation shall be done as per instruction of the Engineer-in-charge of the work.

Energy socket (inner side) should be cleaned before fixing of SBR Gaskets. The gaskets shall be fixed in the grove provided in socket. The spigot end of every pipe should be marked by paint, at a distance 1 cm more than the grove length available at socket end to insure that the proper length of pipes (spigot end) must be gone at socket end at the time of pushing the pipe.

Item No. 4 Lowering, laying and jointing C.I. S&S and D.I. K-9 pipes –----- etc. complete.

The contractor shall clear the site by removing all greases, shrubs etc. before the start of work. The working longitudinal section of pipeline has to prepare by the contractor in consultation with departmental site Engineer. The Engineer – In – Charge may make modifications in the alignment and or level at his desecration, depending on the site conditions. The contractor shall have to fix the alignment and levels shall be done by the contractor at his cost. Laying underground pipes should be lowered into the trench with tackle suitable for the weight of pipes. For smaller sizes, up to 250-mm nominal bore, the pipe may be lowered by the use of ropes but for heavier pipes, either a well designed set of shear legs or mobile crane should be used. When lifting gear is used, the positioning of the sling to ensure a proper balance should be checked when the pipe is just clear of the ground. If sheathed pipes are being laid, suitable wide slings or scissors dogs should be used.

All construction debris should be cleared from the inside of the pipe either before or just after a joint is made. Passing a pull-through in the pipe, or by hand, depending on the size of the pipe does this. When laying is not in progress, a temporary and closure should be securely fitted to the open end of the pipe line. This may make the pipe buoyant in the event of the trench becoming flooded, in which case the pipes should be held down either by partial re-filling of the trench or by temporary strutting. All persons should vacant any section of trench into which the pipe is being lowered.

On gradients of 1:15 or steeper, precautions should be taken to ensure that the spigot of the pipe being laid does not move into or out of the socket of the laid pipe during the jointing operations. As soon as the joint; assembly has been completed, the pipe should be held firmly in position while the trench is backfilled over the barrel of the pipe. The backfill should be well compacted.Supporting Popes above Ground: -

The following recommendations assume that no additional bending moments above those due to the self weight of the pipe and its contents are present.

With spigot and socket pipes-

It is recommended that above ground installations of spigot and socket pipes are provided with one support per pipe, the supports being positioned being the socket of each pipe.

This results in normal distance between supports of 4 m. Pipes should be fixed to the supports with; mild steel straps so that axial moments due to expansion or contraction resulting from temperature fluctuation, is taken up at individual joints in the pipe line in addition, joints should be assembled with the


194

spigot end withdrawn 5 to 10 mm from the bottom of the socket to accommodate these thermal movements.

Pipes supported in this way are capable of free deflection and axial movement at the joints which accommodate small movements of the pipe supports.

Construction of thrust blocks and anchor blocks shall be done in two stages viz, firstly the position below invert of the pipeline shall be casted and then the portion above pipe be casted. Design of individual thrust block and fixity blocks shall be given by the Engineer-in-charge. The distance between two successive fixity blocks shall generally not exceed 500 m.

Where a pipeline crosses water course, the design and method of construction should take into account the characteristics of the watercourse. The concerned authorities may be consulted to ascertain the nature of bed, scour levels, maximum velocities, high flood level, seasonal variation, etc. which affect the design and laying of the pipe line. Early consultation with river authorities; will assist in evaluating the effect of river characteristics (for example, nature of bed, scour levels, maximum velocities, high flood levels, seasonal variations, etc.) on design and construction.

If necessary, unsupported spans between 4 and 6 m may; be obtained be positioning the pipe supports relative to the pipe joints.

With flanged pipes-The recommended maximum unsupported span is 8 m. The supports shall be located at the center of every second pipe.

The recommended maximum unsupported span at watercourse is 8m. The relative positions of pipe joints and pipe supports should be stable.

The supports of all flanged pipe work spans should be stable and; unyielding; due to movements in the pipeline.

The straps should prevent any lateral movement or lifting of the pipe lines but now restrict expansions and constructions caused by temperature fluctuations.

Cutting of pipe-

The cutting of pipe for inserting valves, fittings, etc. shall be done in a neat and workman like manner without damage to the pipe or lining so as to leave a smooth; end at right angles to the axis of the pipe. As far as possible at the time of pipe laying, valves & specials should be laid. Due to non availability of valves, specials if the laid pipes should be cut. That case no payment will be given for the work of the pipe cutting and chamfering of pipes to the contractor. Also the cost of cut piece of pipes shall be recovered from contractor. Methods of cutting ductile iron pipes are given in

By Hacksaw-


Hand or power operated hacksaw should be used with blades having teeth at a pitch of 1 mm.

By manually operated wheel cutter-

The type of cutting; wheel used for cast iron pipes is not suitable for ductile iron pipe. Special wheels, as used for cutting steel pipes, shall be used and; cut ends are trimmed with a file.

By pipe cutting machine-

Machines with cutter heads or abrasive wheels shall be used. Cutter head should have a front rake angle of 7 …. As used for steel pipes.

The flame cutting of pipes by means of an oxyacetylene torch shall not be allowed.

Permissible Deflection at Socket and Spigot Joints: -

When necessary to deflect pipes from a straight line to avoid obstructions or where long radius curves are permitted, deflections at joint shall not exceed following

Rubber JointsFor nominal Bore – 80 mm to 300 mm 5 DegreeFor nominal Bore – 350 mm to 450 mm 4 DegreeFor nominal Bore – 450 mm to 750 mm 3 Degree

End preparation of cut pipes for jointing – The barrel left after cutting should be trimmed off by light grinding or by filling.

Wrapping-

when ductile iron pipes are to be laid in aggressive soils; the pipes should be wrapped externally with protective coatings. , such as bitumen or coal tar sheathing protective tapes or by loose polythene slaving, or in certain; circumstances, concrete before laying. At joints, bends and valves, precautions should be taken to provide sufficient overlap of the wrapping sleeve so that no pipe line is exposed to the aggressive soil.

Pipe line markers-

Distinctive markers should be erected at all roads, railways, river and canal crossings, and elsewhere as required to identify the pipe line and to indicate its position. Markers should be placed at field boundaries, preferably; in such a way that they are not obscured by vegetation. At all valve installations, plates should be provided to give the same information as on the makers. Markers should not be treated with any substance likely to be harmful to live stock.


196

Pipe line Anchorage-

All pipe lines having, unanchored flexible joints require anchorage at changes of direction and at dead ends to resist the static thrusts developed by internal pressure. Dynamic thrusts caused by flowing water act in the same direction as static thrusts. This thrust is of sufficient magnitude at high; velocities; to warrant safety consideration.

Anchorage’s to resist the thrust should be designed taking into account the maximum pressure the main is to carry in service or on test, and the safe bearing pressure of the surrounding soil.

Where possible concrete anchor blocks should be of such a shape as to allow sufficient space for the remaking of the joints.

Laying Procedure: -

Laying of DI pipes shall be done as per I.S. 12288/1987 and as amended from time to time. Rubber gaskets (SBR rings) are to be provided. SBR gasket shall conform to IS 12820/1989 or latest edition. Lowering, Laying and jointing of pipes shall be carried out as per standard specifications no. Bd-V-1.4 page 548 and as per standard specifications No. Bd-V-1.4 page 549 and as per standard practice in MJP Organization and as directed by the Engineer-in-charge. DI pipes shall be jointed with the CI specials with the help of CI mechanical joint. The jointing operations of mechanical joint shall be done as per instructions given in the literature of the firm manufacturing the mechanical joint. This operation shall be done as per instruction of the Engineer-in-charge of the work.

Energy socket (inner side) should be cleaned before fixing of SBR Gaskets. The gaskets shall be fixed in the grove provided in socket. The spigot end of every pipe should be marked by paint, at a distance 1 cm more than the grove length available at socket end to insure that the proper length of pipes (spigot end) must be gone at socket end at the time of pushing the pipe.

HYDRAULIC TESTING

1) After laying and jointing, the pipe lines shall be tested under pressure by hydraulic test pumps to ensure that pipes and joints are strong enough to withstand the maximum pressure likely to be developed under the working conditions.2) The field test pressure to be imposed shall not be less than the greatest of the following.

i) 1.5 times the maximum sustained operating pressure.


ii) 1.5 times the maximum pipe line static pressure.iii) Sum of the maximum sustained operating pressure or the maximum pipe surge pressure.

Subject to a maximum equal to the work pressure for any pipes

Any fittings incorporated to the pipe line.The field test pressure should wherever possible be not less

than two third of the working pressure, test pressure appropriate to the class of pipes and shall be applied and maintained at least 4 hours.

Where the field test pressure is less than 2/3 the test pressure, the period of test shall be increased to at least 24 hours. The test pressure shall be gradually raised at the rate of nearly 1 Kg/ min.In the case of spun iron pipes, the hydrostatic test pressure after installation is to be adopted instead of works hydrostatic test pressure which is 50 Kg/ Sq. cm. uniformly for all classes of pipe. If pressure measurement is not made at the lowest point of the section, an allowance shall be made for static head between the lowest point and the point of measurement to ensure that the maximum pressure is not exceeded at the lowest point. If 10m. Drop in pressure occurs the quantity of water added to re-establish the test pressure shall be carefully measured. This shall not exceed 0.11 liters per minute of pipe dia per km. of pipe line per day or each 30m. Head of pressure supplied.

METHOD OF PRESSURE TESTING.

The pipe line shall be tested for soundness in portions as laying is in progress. The procedure for the test as adopted generally is as under.

1) At a time one section of the pipe line between two sluice valves, is taken up for testing. The section usually taken in about 300 to 500mts. Long.2) One of the valves is closed that water is admitted into the pipe line through the other end by means of the hand operated pump by releasing the air suitably, through the cocks provided and fixed for the this purpose. The necessary power pump with small capacity may also be installed to fill the pipe line and raise the pressure. However hand pump can be tried as a supplementary arrangement.3) After filling, the section of the pipe line, the sluice valve is to be closed and the pipe section is isolated. 4) Pressure gauge will be fitted at suitable interval on the crown into the holes meant for the purpose.


198

5) The pipe section is then connected to the delivery side of a pump through a small valve.6) The pump is then worked fill the pressure inside reaches the designed value which can be read from the pressure gauge already fixed.7) After the required pressure has been applied, the valve shall be closed and the pump be disconnected.8) The pipe shall then kept under the desired pressure for at least two hours during inspection for any defect i.e. leakage’s of joint etc. The pipe line shall be than emptied through scour valves and defects observed in the test shall be rectified.

The hydraulic testing of the pipe line should be invariably carried out before back filling is done. A log book should be maintained by the J.E. on site showing details as below.
