New Stock Arrival Leak Proof UV Stabilized PE Plastic Water Pipe for Tunnel Auxiliary Cabling

The flange must be smooth, full, and uniform without bulges, cracks, or blackening. The transition to the pipe wall must be natural without gaps. Non-compliance includes significant width variation, blistering, or suspended flanges.

The cross-section must show dense fusion with no cracks, porosity, or layering. The PE base material and fusion zone must be seamlessly integrated with no distinct boundary. Defects like layered cracking, pores, carbonized particles, or single-sided fusion require rework.

PE is an electrical insulator that does not decay, rust, or undergo electrochemical corrosion. It resists a wide range of chemical substances in soil and does not promote algae or bacteria growth.

Pipes containing 2-2.5% uniformly distributed carbon black can be stored or used outdoors for up to 50 years without damage from ultraviolet radiation.

Edge trimming must use a dedicated hot-melt edge-trimming tool for uniform circular cutting. Rough removal with chisels is prohibited. Photographs must be taken for record-keeping after trimming.
