HDPE lined steel pipe

HDPE lined steel pipe slightly larger than the outer diameter of tube technology is the main channel diameter HDPE liner, after necking, making cross-section smaller than the cross-sectional area of the main channel, in the role of traction quickly insert the main channel. Rely on their memory characteristics HDPE liner or with pressure and temperature to rebound swelling HDPE liner diameter, HDPE liner attached to the outer wall of the main channel interference inner wall of the tube to form a solid tube.

HDPE is a high crystallinity, non-polar thermoplastic resin. Original state of HDPE milky white appearance, thin cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of living and industrial chemicals. Certain types of chemicals will undergo chemical corrosion, such as corrosive oxidizer (nitric acid), aromatics (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good water vapor permeability, can be used for packaging purposes. HDPE has good electrical properties, especially the best edge high dielectric strength, making it suitable for wire and cable. The high molecular weight grade with excellent impact resistance even at low temperatures are-40F so at room temperature.

HDPE carbon pipe is the high-density polyethylene pipe, which has a high strength, high toughness, corrosion resistance, high temperature, high insulation resistance, flame retardant, light weight, long life, a variety of advantages, such as easy deformation, the carbon bellows has been widely used in underground engineering city street line, electrified railway power, communication cables laid underground engineering, highway electricity, communications facilities construction and renovation project, the construction of residential quarters and large entertainment venues and parks buried cable project, is currently the best underground cable jacket pipe.
