standards and acceptance. All the tests carried out under the Work Order will be witnessed by Department Representative.

4.2 WELDING PROCEDURE AND WELDER PERFORMANCE

All the welding shall be carried out by qualified welder(s). Welding procedure & welder performance qualification tests shall be carried out

in accordance with section IX of ASME. At least six welders shall be qualified for the work.

Department will supply only the pipes and the remaining materials

required for the test shall be brought by the contractor. The size of tubes/ pipes range from 8 mm to 300 mm and thickness of the pipes

range from 1 mm to 14 mm. Test procedure, specimen preparation, NDT testing, tensile test, bend test etc shall be done as per sec IX of

ASME and any other requirement specified by the Department at the time of execution of the work. The welder qualification and weld procedure qualification test shall be

carried out under the inspection of System Reliability Group (SRG) of Department. If the welder is already qualified, then the certificate shall

be submitted to Department for review & approval.

4.3 INSPECTION

Inspection of welding works will be carried out generally in the following manner:

� Preliminary check � Checking of welding procedure

� Checking of the quality of weld joints

Preliminary checks

� Checking whether qualified welder is being engaged for the work. Also checking of the qualification or other allied

operating personnel.

� Checking the state of the appliances, instruments and devices used for welding and inspection.

� Checking the quality of welding materials, their correspondence with the certificates and their storage conditions.

� Checking the quality of preparation of the weld joint. Measuring the weld geometry and checking the fit-up assembly for conformance to the required norms.

17

Checking of Welding Procedure

� Checking whether qualified procedure is being adopted.

� Monitoring and Recording all the essential parameters for each weld.

Checking the quality of the weld joints

� External inspection of the weld joint. � Dye penetrate test (DPT).

� Radiography examination.

4. 4 NORMS OF QUALITY CONTROL

- All weld joints shall be subjected to external examination to

detect weld defects. - The quality norms with acceptance limits for external

examination of piping are as per ASME. - Radiography examination of the weld joints shall be done only

after elimination of defects detected by the external inspection.

- There are three categories of weld joints as given below;

� Weld category - I � Weld category – II

� Weld category - III

- The weld joints of category-I are to meet stringent quality

standard because these joints are subjected to high operating pressure, flammable & explosive fluid media, high dynamic

loads etc. All butt weld joints of category-I shall be subjected to 100% radiography.

- The weld joints of category- II are subjected to low operating

pressure, vacuum, etc. All butt weld joints of category-II shall be subjected to 10% radiography examination and such weld

joints will be identified for test by the inspection personnel of the Department.

- The weld joints not included in the aforesaid two categories

are related to the III category. Generally welding of supports,

structural welding is falling in the III category.

4.5 ELIMINATION OF WELD DEFECTS

- Elimination of weld defects shall be carried out in the presence

or with the concurrence of the inspection personnel of

Department.

18

- The weld joints which are found to be defective in X-ray

examination or strength test or leak test or vacuum leak proof ness test shall be subjected to the same type of check/testing

repeatedly after rectification work until all the checks / tests are passed successfully.

- Length of the defective segment is to be determined before

preparation of the edges for re-welding and the width of the edge preparation is determined by the nature of the defect.

- Width of the weld after re-welding shall not exceed double the

width of the weld existed earlier.

- Weld sagging, under cuts and hollows between beads shall be eliminated by welding again over the defective place after

polishing such spots to get bright metallic surface.

- For repairing joints with incomplete fusion, inclusions, cracks

etc. (internal weld defects) the material shall be removed till the defects are completely eliminated from the job and then re-welding shall be done.

- The repair of weld joints by re-welding at the same place is allowed only up to 2 times.

- After elimination of defects, the pipeline shall be purged with

GN2.

- During repair works in the defective joints, ensure chips, dust and other contaminations do not enter into the pipelines.

- Subject the repaired welds to repeated checks as well as tests

for strength, leak proof ness etc.

the tee is to be added to the overall length.

d. Insulated reducers connecting two different diameters of pipes

shall be reckoned as equivalent piping of larger diameter for purpose of measurement of insulation.
