General InformationPSI Plastic Insulators System

Polypropylen insulators are universallyapplicable in the installation of pipelineswhen the carrier pipe runs inside acasing.

Plastic insulators provide variousadvantages:– easy installation of the carrier pipesince the plastic material reducesthe friction coefficient to a minimum

– minimised friction prevents damageto the protective coating andinsulation of the pipes

– a wide range of skid heights ensuresconcentricity of the carrier pipe inthe casing if required

– excellent insulating properties ofthe plastic material ensures: allrequirements of cathodicprotection are met.

Plastic insulators are suitable for all pipediameters from 25 mm upwards andmany skid heights are available to suitspecific requirements.

125

Technical DataPSI Plastic Insulators System

Polyolefines have a good friction coefficient due to steel wax like surface.The sliding friction coefficient is 0,2 – 0,3 as for steel has a coefficient of 1,0.Therefore the abrasion is reduced to a minimum.The material is strong and yet flexible and is therefore resistant to stresscracking.Flexibility of the body, stability of the skid form and excellent dielectricinsulation are some of the good characteristics of this material.

Plastic insulator rings are normally installed with the following spacingbetween the rings:

- pipe dia up to 300 mm at a spacing of 2,5 m- pipe dia 400 – 600 mm at a spacing of 2,0 m- pipe dia > 600 mm at a spacing of 1,5 m

Please contact us if you want to use larger spacing between rings.

General InformationPSI Plastic Insulator Ring Type PA/PE System

Type PA/PE insulator rings are available for a pipe O.D. from 25 to 336 mm.They consist of two halfshell-segments. The nuts and bolts required forassembly are included.

The type code indicates the carrier pipe O.D. in inch and the skid heightin mm (e.g. PA/PE 4-38 = carrier pipe 4", skid height 38 mm).

The skid height is calculated from the difference in diameter of the carrierpipe and the casing. It is important to consider the actual dimensions,including coatings, rather than the nominal sizes.

Example: - PE- coated carrier pipe ND 100- O.D. (117.9 x 5.2 mm)- Steel casing ND 200 (219.1 x 6.3)- I.D. 206.5 mm- Carrier pipe O.D. 117.9 mm = 88.6- 88,6 : 2 = 44.3 mm skid height- Suitable type: PA/PE 4-38

After determining the skid height, the next lower height is selected fromthe table (e.g. 44.3 mm, ideal skid height = 38 mm).

The segments can be assembled with the corrosion protected steel boltsDIN 912 and nuts DIN 562 included.On request we supply plastic bolts (similar to DIN 84) and nuts (DIN 555).

Up to type PA/PE 4 the insulator rings have 4 skids; from type PA/PE 6up to 6 skids are provided. The following table gives the technical detailson available sizes, skid heights of the various types and carrier pipediameters.

General InformationPSI Plastic Insulator Segments Type AZ/AC System

AZ/AC insulator rings are used for a pipe O.D. from 98 to 385 mm andconsist of several segments. The number of segments depends on thecarrier pipe's O.D.. The nuts and bolts required for assembly are included.

The universal applicability of type AZ/AC provides two special advantages:– variable ring diameter, which is especially important for thick-walledpipes whose O.D. substantially deviates from the nominal size(e.g. AZ/AC pressure pipe ND 16 - vitrified clay pipes);

– only two segment sizes are required to assemble ND 100 to ND 350insulator rings - a decisive edge in stock-keeping.

The skid height is calculated from the difference in diameter of the carrierpipe and the casing. It is important to consider the actual dimensions,including coatings, rather than the nominal sizes.For an example calculation refer to type PA/PE.

The following table gives the technical details on available sizes, skidheights of the various types and carrier pipe diameters.

Installation InstructionPSI Plastic Insulator Type GKO-gl and GKO-gs System

Put out spacerelements andwedges accordingto selection table.Connect elements asa spacer band (for positionof the wedges per spacerelement see selection table on thebackside), put the mounting linkwith grid into the entry of next element,be aware of parallelism. Push wedgesinto the lateral fixing slot until top can beseen on the other side of the spacer. Mindthe direction of the arrows.

On smooth pipe surface which are in contact with the spacers (e.g. PE, PVC,steel/cast on PE-coated or stoneware) wrap a shear-secure-tape to guarantee anoptimum security against slipping.

Put pre-mounted elements around the medium pipe and close last joint. Shift thespacer ring together by hand.

Shift spacer elements together with a screw clamp as far that one or morewedges can be put in the next fixing slot.

Drive in all wedges with hammer strokes parallel to the pipe. The wedges don’thave to be in fully.

Attention:The lashes of the smaller pipe diameters (DN 400 – 600) have to be slightly bentdownwards for an easier insertion.

When mounting more spacer rings please be aware that the skids of the singlemounted rings align together.

General InformationPSI Plastic Insulator Segment Type MA System

Starting with a pipe O.D. of 402 mm, MA insulator rings consisting of twosegment sizes (MA and MA2) and various skid heights are used to suit therespective pipe O.D.

The special advantage of these insulators is their universal applicability.The following rule is used to determine the composition of suitable insulatorrings:– for every 100 mm of pipe O.D. = 1 MA segment– for every 50 mm of pipe O.D. = 1 MA 2 segmentExample: Carrier pipe O.D. 559 = 5 MA segments + 1 MA 2 segment.

The segment's skid height is calculated from the difference in diameter of thecarrier pipe and the casing.For an example calculation refer to type PA/PE.

The nuts and bolts required for assembly are included.

The following table gives the technical details on available sizes, skid heightsof the various types and carrier pipe diameters.

RGV insulator rings are used from a pipe O.D. of 500 mm. They differ fromMA types in having two reinforced load-carrying centre solid skids persegment. The fastening skids (36 mm high) are for connection only. Toobtain the required pipe O.D., RGV segments are combined with RGV 2segments.

Special advantages of these insulator rings are their high static load-carrying capacity and their versatility. The following rule is used todetermine the composition of suitable insulator rings:– for every 100 mm of pipe O.D. = 1 RGV segment– for every 50 mm of pipe O.D. = 1 RGV 2 segmentExample: Carrier pipe O.D. 559 = 5 RGV segments RGV +1 RGV 2 segment

The segment's skid height is calculated from the difference in diameter ofthe carrier pipe and the casing.For an example calculation refer to type PA/PE.

The nuts and bolts required for assembly are included.

The following table gives the technical details on available sizes, skidheights of the various types and carrier pipe diameters.

Installation InstructionsPSI Spacers Type RGV

Put out elements of spacers andscrews according to selection table.Connect elements as a spacer bandand fix the nuts on the screws withjust a few rotations.

On smooth pipe surfaces (e.g. PE, PVC,steel/cast on PE-coated or stoneware)wrap a shear-secure-tape to guaranteean optimum security against slipping.

Put pre-mounted elements around themedium pipe and close last joint.

Draw the screws equally tight toreceive equal pitches between thespacer elements.

Square nuts have to fit into thedesigned cavity of the spacersegment.

Tighten screws with a torque momentof max. 8 Nm to fix the spacer ringirremovable on the pipe.Screws don’t have to be necessarilycompletely contracted.

PSI-warranty is limited on the substitute of faulty material. The suitability of theproduct has to be tested for the special use by the user self dependent.

AccessoriesPSI Plastic Insulator System

Some insulators can be supplied with a plastic support for cable pipes. Theyare fastened by means of straps. For this purpose the support is equippedwith a groove. On request we can supply stainless steel straps and clamps.

The piggyback is welded to the insulator by hot riveting.

Also available for PVC and PE pipes as well as for PE-coated steel pipes.This lining remarkably increases the adhesion of the insulators to the smoothpipe surface.

A screw clamp is required to form the ring if the distance between thetwo end segments is too large.

Butyl rubber tapes for very smooth pipe surfaces, rolls with 15 mm,width 50 and 100 mm.
