Steel Wire Mesh Skeleton Reinforced Hdpe Pressure Pipe For Fire

Product Overview

Baishunxing Pipe Industry HDPE Steel Wire Mesh Skeleton Composite Pipe is a new type of composite pipe reinforced by a high-strength steel wire mesh skeleton (wound helically in both left and right directions) and integrated with high-density polyethylene (HDPE) as the matrix. It is continuously manufactured on a production line using high-performance adhesive resin. It overcomes the corrosion vulnerability of steel pipes and solves the creep issues of pure plastic pipes under high pressure.

Key Features

High Strength & Pressure Resistance: The steel wire mesh skeleton acts as the core reinforcement, giving the pipe rigidity similar to steel and extremely high pressure-bearing capacity, with pressure ratings up to 2.5 MPa .

Excellent Creep Resistance:Due to the steel wire skeleton, the pipe exhibits excellent dimensional stability under long-term pressure, effectively preventing the creep deformation common in plastic materials.

Low Thermal Expansion Coefficient: The steel wire mesh restricts the thermal expansion and contraction of the HDPE, resulting in a linear expansion coefficient much lower than that of pure plastic pipes, making it suitable for environments with large temperature fluctuations.

Double-sided Corrosion Resistance & Traceability:Both the inner and outer walls are made of HDPE, providing superior corrosion resistance. Additionally, the metal skeleton allows the pipe to be easily located with magnetic equipment, facilitating future maintenance.

Major Advantages

The connection of HDPE steel wire mesh skeleton composite pipes produced by Baishunxing Pipe Industry is highly reliable:Primarily joined by electrofusion, where the heating coils inside the fitting fuse seamlessly with the pipe surface, ensuring joint strength higher than the pipe itself for a permanent seal.

Wear Resistance & Smooth Inner Wall:The smooth inner wall offers minimal fluid resistance. Furthermore, the wear resistance of HDPE is several times that of steel, making it ideal for transporting sand and slurries.

Strong Construction Adaptability:The pipe possesses a degree of flexibility, allowing it to adapt to complex terrain changes and ground settlement. Compared to steel pipes, it is lighter and easier to install.

High Cost-Effectiveness:While the unit price is slightly higher than pure plastic pipes, its extra-long service life (over 50 years) and minimal maintenance frequency significantly reduce the lifecycle cost of the project.

Typical Applications

Municipal Water & Firefighting:Urban high-pressure water supply networks and underground fire-fighting water systems.

Industrial Process Piping:Transport of various acid, alkali, and salt solutions in chemical, metallurgical, paper, and pharmaceutical industries.

Mining & Tailings Transport:Mine drainage, ventilation, and long-distance transport of high-concentration tailings slurry.

Oil & Gas Industry:Oilfield water injection, crude oil collection, and low-to-medium pressure natural gas transport pipelines.

FAQ

1. What is Steel Wire Mesh Skeleton Reinforced HDPE Pressure Pipe for Fire Protection Systems?

Steel Wire Mesh Skeleton Reinforced HDPE Pressure Pipe for Fire Protection is a high-performance composite pressure pipe that combines a reinforced steel wire mesh skeleton with high-density polyethylene (HDPE) layers.
