With years of excellent experiences on LSAW Pipe and Pipe fittings, Hebei Canghai Nuclear Equipment Technology Co.Ltd. has became the reliable supplier and partner to our clients in pass decades.PE insulation pipe is also known as PE outer protection pipe,jacket pipe, sleeve pipe. The outer protective layer of the directly buried polyurethane insulation pipe is HDPE insulation pipe, and the middle is filled with polyurethane rigid foam as the insulation material layer, and the inner layer is steel pipe. Polyurethane directly buried thermal insulation pipe has good mechanical properties and thermal insulation properties with good impact resistance. Under normal circumstances can withstand the high temperature of 120-180°C, suitable for all kinds of cold and hot water high and low temperature pipeline insulation engineering. It is usually used in indoor and outdoor pipelines, central heating pipes, central air conditioning pipes, chemical and pharmaceutical industrial pipelines of insulation, cold engineering, oil pipeline engineering, etc. Insulation pipe production line adopts special PE insulation pipe mold design, extrusion pressure is stable, thin wall pipe thickness uniform. The extrusion speed is fast, the blow molding output is greatly improved, the surface is brighter, and the operation is highly automatic.
