Before applying the layup on this area, insure all solvent has pletely evaporated. Never allow spilled chemical on the pipe surface.

Receiving, Handling and Storing of PipeDetails see attachment B: Installation and Handling Instructions For Rigid Joint Pipe Page 2 to 4.Inspecting Pipe● All pipes receiving at site shall be inspected according to Specification for Piping Material. ● Broken pipe bundles, crushed fittings boxes should be checked carefully, scratched and gouged and pipe with crushed or split ends are not allowed to use, damage claims procedures must be initiated prior to accepting the shipment.● Do not dispose of any damaged items. If any imperfection or damage is found, immediately segregate the affected pipes and contact Dealim. Do not use pipe that appears damaged or defective.Handling Pipe● Pipes, fittings and prefabricated parts (spools) have to be transported by suitable trucks. These trucks must have flat floors. Check and remove any projections or nails etc. before each load. Materials must be secured for example by using wedges and wooden supports. These supports must have a minimum width of 10 cm, avoiding sharp edges. The support distances must not exceed m.● Do not lift the pipe by passing a rope through the section end to end.● Any part of the truck has to be protected by wood or rubber wherever in contact with the products. If pipes are handled by a forklifter, the forks must be covered with rubber or plastic.● For work on the pipe, such as cutting, preparing ends, or cleaning, twopoint support is remended for 20foot lengths, and threepoint support for 40foot lengths. Support wood should be ensured no nails.● The best way for fittings to be transported is in crates or onto pallets. Direct contact between products during transport must be avoided.Pipe Storage● Do not lay the pipes directly on the ground, rails or concrete floors.● Ensure suitable supports are used for example wooden beams, measuring 10 x 5 cm.

The machined ends must be protected for example by polyethylene covered straw mats or polyethylene netting.● If the product is stacked too high for long storage periods (612 months).
