Bovengrondse voorgeïsoleerde stalen buizen

De voorgeïsoleerde stalen buis bestaat uit een stalen buis, HDPE Omhullingsbuis and jacketed foaming, which is used for insulation and cooling of indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical industry, medicine and long-distance transportation pipelines of petroleum. The above-ground steel pipe is a type of fiberglass jacketed, spray-applied polyurethane foam insulated piping system for above ground for centralized district heating or distribution of liquids from -320°F to 250°F.  The polyurethane system with foaming provides maximum thermal efficiency to optimum performance of cryogenic and very low heat conductivity coefficient.

 

HDPE Casing

Outside casing pipe is manufactured from high-density Polyurethane with added antioxidants, UV stabilizers and carbon black. The internal surface of PE pipes is processed with Corona treatment in order to achieve better adhesion with PUR foam.
