Pipeline Coatings | WPC

Product description

WPC field-joint coating.

  • Construction: two-layer system:
  • First layer: Visco-elastic low preheat sealant adhesive.
  • Second layer: Thick-walled, radiation cross-linked, high density polyethylene with PCI(Permanent Change Indicator).

WPC is a wraparound heat-shrinkable, ready-to-fit assembly for the corrosion protection of field girth weld joints in distribution and transmission systems.WPC is compatible with standard pipe coatings.

WPC can also be used for coating bare, replacement pipe sections and large radius bends. The system is designed to be applied with minimum preheating and is ideal for large diameter water pipe.

The installation is carried out directly on the cleaned and dried (pre-heated) pipe surface without any primer being required. During installation, the heat shrinkable sleeve is wrapped and shrunk to form a tight fit around the joint.

During recovery, the adhesive softens and flows to form a perfect bond with the pipe surface providing protection against corrosion. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.
