Product Details

The pre-insulated steel pipe is composed of carrier steel pipe, HDPE Casing pipe 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 pre-insulated 90°/45° elbow is a type of fiberglass jacketed, spray applied polyurethane foam insulated piping system for below ground 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.
