Hole steel belt polyethylene composite pipe is a composite material that uses cold-rolled steel strip welded into a perforated pipe as the reinforcing skeleton, and is compounded with thermoplastic plastics. 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 pressure resistance of the pipe material is significantly enhanced, capable of withstanding greater pressure and external loads.

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

Excellent impact resistance: High ring stiffness and impact resistance, capable of adapting to complex construction and usage environments.

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

Good hygiene: Smooth inner wall, no scaling, 30% lower water head loss than steel pipes, and meets relevant hygiene standards, suitable for drinking water transportation.

Long service life: Up to 50 years under normal conditions.
