PurposeThis method statement is to guide butt joint wrap lamination work of U/G GRP piping system in the Arabian Chlor Vinyl Project.2. ScopeThis Method Statement covers the field lamination joints installation method of underground GRP piping. This procedure is applicable to all U/G GRP pipe diameters.Related data of U/G piping GRP part is as following:System descriptionMaterial classDiameter rangeConnection MethodW WDGAANA4”,6”,8”,10”,12”,20Butt amp。 Wrap Joint Procedure Page 12 and attachment B: Installation and Handling Instructions For Rigid Joint Pipe Page 7.11. Quality Requirements1. The joint specification should be verified as per the AMIANTIT process.2. Visual inspection of the laminated joints for external layup.3. Checking the lamination thickness using the measuring tapes also the lamination width.4. Barcol hardness to check the lamination hardness should not be less than 30HBa.5. Full water test is used for gravity flow pipe when it’s pleted. During test for filling with water, the piping shall be full of water, it will be accepted if the water level not lowering.6. Before buried, the coordinates and elevation of the pipe should be checked as per posite drawing.7. All quality inspection work should be according to ITP from DEALIM.12. Safety PrecautionForbidden under loading/hoisting the pipe by passing a rope through the section end to end.Don’t use unsafety machine when cutting and grinding, antidust coveralls clothes, full face shield and dust mask should be used for grinding.Chemical splash goggles is remended for chemicals operating。3 After the filling of the gap, the putty shall polymerize, without moving and bumping the pieces. 4 Once pleted the hardening of the putty, grind the outside of the pipe joint and clean with air blow and clean duster cloth.Note : The gap should not exceed the 5 mm or as per remended by Pipe manufacturer at any case.
