20mm To 1600mm Polyethylene Composite Pipe Perforated PE Pipe For Water Supply

Perforated Steel Strip Reinforced PE Pipe is an advanced, high-strength composite piping system engineered to bridge the gap between traditional steel pipes and conventional plastic pipes. It is specifically designed to handle high-pressure fluid transportation in harsh municipal, industrial, and mining environments.

The pipe features a unique multi-layer composite structure. The core reinforcement layer is made of a high-strength steel strip that is precision-perforated and welded helically into a mesh skeleton. Through a continuous, one-step extrusion process, this steel core is seamlessly fused and encapsulated with inner and outer layers of High-Density Polyethylene (HDPE) or Heat-Resistant Polyethylene (PE-RT).

Applications 

Apart from standard civil applications—such as municipal and building water supply & drainage, potable water, heat network return water, natural gas, and gas transmission pipelines—this product offers the following unique applications that other plastic composite pipes cannot achieve:

Municipal Utility Tunnels : Ideal for water supply, drainage, and electrical conduits within urban utility tunnels, offering vast market prospects.

Urban Construction : Perfectly suited for vertical riser pipes in high-rise buildings for both water supply and drainage systems.

Above-ground / Aerial Installation : Excellent for areas where excavation and underground burying are impractical, allowing for direct above-ground installation.

District Heating : Manufactured using Heat-Resistant Polyethylene (PE-RT), these pipes are highly effective for urban heating networks.

Thermal Power Engineering : Widely used for the transportation of process water, industrial slag, and waste residues.

Product Advantages

• High Rigidity & Excellent Creep Resistance : The pipe features robust rigidity and superior resistance to deformation, making it highly suitable for above-ground/aerial installation.

• Delamination-Free & Seamless Integration : The reinforcement skeleton and plastic layers are integrated seamlessly into a single entity. The inner and outer plastic layers are virtually inseparable without the use of chemical adhesives. By utilizing hot-melt sealing rings and electrofusion fittings, the connection process is identical to standard plastic pipes, eliminating any risk of delamination between the plastic and the steel skeleton.

• Outstanding Corrosion & Creep Resistance : It combines the low linear expansion coefficient and strong creep resistance of steel pipes with the excellent corrosion, heat, and static resistance of plastic pipes. It boasts a service life of up to 50 years.

• One-Step Extrusion & Smooth Inner Wall : Manufactured via a continuous one-step extrusion and composite molding process, ensuring highly uniform wall thickness and an ultra-smooth inner surface that optimizes fluid flow.

• Flexible Wall Thickness & Exceptional Cost Efficiency : The wall thickness is not constrained by the steel skeleton, allowing for flexible modifications. Compared to pure PE pipes of the same specifications and pressure ratings, it can reduce material costs by 30% to 60%.
