Hole net steel belt polyethylene composite pipe is a composite material that uses cold-rolled steel strip-welded hole net pipe as the reinforcing skeleton, combined with thermoplastic plastic. Below is a detailed introduction to it:

Structure and Principle

The steel frame of the steel-belted polyethylene composite pipe on Kongwang is formed by rolling and welding after punching the steel strip. The reinforced frame is integrated with the plastic, making the inner and outer plastic layers almost non-detachable. There is no adhesive in the composite layer, combining the advantages of steel and plastic pipes.

Performance Features

High strength and pressure resistance: With a steel strip reinforced frame, the pipe material's pressure resistance is significantly enhanced, capable of withstanding greater pressure and external loads.

Corrosion and abrasion resistance: The plastic layer on both inner and outer walls provides excellent corrosion resistance, effectively resisting erosion from acids, alkalis, salts, etc., and boasts good abrasion resistance, about four times that of steel pipes.

Excellent impact resistance: High ring stiffness and impact resistance allow it to adapt to complex construction and usage environments.

Low linear expansion coefficient and thermal conductivity: Possesses the characteristic of low linear expansion coefficient of steel pipes, with a low thermal conductivity, offering good thermal insulation properties.

Excellent hygiene: Smooth interior wall, no scale buildup, 30% lower head loss than steel pipes, and meets relevant hygiene standards; suitable for drinking water transportation.

Long lifespan: Up to 50 years under normal conditions.
