The pre-insulated steel pipe is composed of carrier steel pipe, HDPE Casing pipe and jacketed foaming, which is used for widely used to protect steel pipe used in pipeline construction, concrete reinforcing bars and on a wide variety of piping connections, valves and long-distance transportation pipelines of petroleum from corrosion. .The pre-insulated pipe fitting is used for the connection of a pre-insulated coated pipe.

The carbon steel pipe elbows insulation are generally 90° and 45°. It 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.


Carrier pipe (Inner pipe) can be:

API 5L Gr. B X42 X46 X52 X56 X60.

ASTM A106/53 Gr. A /Gr. B / Gr. C

APL 5CT:J55, K55, N80, L80, C90, T95, P110

The excellent adhesion of PE to steel can make sure the superior long term corrosion resistance and protection for pipelines. And it can reduce the total cost of cathodic protection during the operation of the pipeline. As one of the leading suppliers and manufacturers of coating carbon steel pipe in China, WLD steel supply the high-density Polyethylene jacket steel pipe and PE coated pipe fittings according to AWWA standard for applications in buried or submerged applications. With the partnership of the major steel mills in China, comprehensive advanced coating measures are provided for your pipe needs.
