Product Description

Product Description

 

The steel reinforced polyethylene plastic pipe is a composite structure pipeline continuously produced in a production line. It is concretely produced through uniformly compounding a wound and weld-molded steel wire mesh and polyethylene or other thermoplastics, with the weld-molded steel wire mesh as a reinforcement frame and the polyethylene or other thermoplastics as a matrix. The raw material for producing the steel reinforced polyethylene plastic pipe are high-density polyethylene(HDPE) resin or medium-density polyethylene (MDPE) resin (for fuel gas conveyance), and low-carbon steel wires. It is mainly used for conveyance or mixed convey- ance of petroleum, natural gas industry oil, gas and sewage, and can also be used for conveyance of water or other corrosive liquids. The applied temperature of steel reinforced polyethylene plastic pipe is-40 ºC

Product Features

Note: When ND ≥ 250 and PN ≥ 2.0, due to the increase in PN, the wall thickness increases inward, allowing the minimum average inner diameter to fluctuate downward by no more than 1.5mm compared to the values in the table.
The main body of a pipe refers to the part of the pipe body that bears all internal pressure.
