The steel mesh skeleton plastic composite pipe is a new and improved steel skeleton plastic composite pipe. This type of pipe is also known as SRTP pipe. This new type of pipe is made of high-strength over-plasticized steel mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. It uses high-density polyethylene (HDPE) as the matrix and uses high-performance HDPE modified bonding resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, giving it an excellent composite effect. Because the high-strength steel wire reinforcement is coated in continuous thermoplastic, this composite pipe overcomes the respective shortcomings of steel pipes and plastic pipes, while maintaining the respective advantages of steel pipes and plastic pipes.

Steel mesh skeleton plastic composite pipe adopts high-quality materials and advanced production technology to make it have higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline systems. The pipe fittings used in steel mesh skeleton polyethylene composite pipes are polyethylene electrofusion pipe fittings. When connecting, the heating element inside the pipe fitting is used to melt the outer plastic layer of the pipe and the inner plastic layer of the pipe fitting to reliably connect the pipe and pipe fitting together.

• Steel wire reinforced composite structure, ultra-high pressure-bearing performance

  The high-strength steel wire mesh frame is reinforced with winding, can withstand pressure up to PN1.6–PN10.0MPa, resists water hammer impact, and will not burst the pipe under high-pressure conditions;

  Comply with CJ/T 189

• Double-layer SSPE coating, excellent anti-corrosion and anti-penetration performance

  The inner and outer layers are made of special high-density polyethylene, which is resistant to acid, alkali, salt, groundwater, and soil corrosion, and does not scale or leak;

• Steel-plastic balance of rigidity and toughness, resistance to deformation and settlement

  The rigidity is better than pure PE solid wall pipe, the flexibility is better than steel pipe, it resists foundation settlement, geological displacement, ground rolling, and is not brittle in low temperature environment;

• Anti-creep, anti-fatigue, stable for long-term high-pressure operation
  

  Resistant to slow crack growth, resistant to alternating hydraulic pressure impacts, long-term pressure bearing without relaxation, suitable for long-distance pressure transmission pipeline networks;

• The inner wall is smooth and low resistance, high conveying efficiency and low energy consumption
  

  The inner wall roughness is ≤0.007mm, the water flow resistance is small, and impurities are not easily deposited, which reduces the energy consumption of the water pump and is suitable for water supply, fire protection, and chemical media transportation;

• Special electrofusion connection, high-voltage component connection, tight sealing and zero leakage
  

  It is equipped with special electrofusion pipe fittings, Kangyu's unique high-voltage component connection, and the steel-plastic interface is melted and sealed in one piece. The interface has high strength and is suitable for high pressure, negative pressure, and long-distance pipe networks;

• Light weight, convenient and efficient construction and installation
  

  The dead weight is much lower than that of steel pipes of the same specification, which is convenient for transportation, hoisting, underground and field laying. Coils with diameters of 50mm-225mm can be customized to reduce joints;

• Insulation and anti-static, outstanding safety performance
  

  Non-metallic insulating material, which can be anti-statically modified to avoid stray current corrosion and spark hazards. It is suitable for factories, mines, and chemical industrial parks;

• Weather-resistant and anti-aging, strong environmental adaptability

  Applicable to a wide temperature range of ‑40°C to 60°C, resistant to sunlight, freeze-thaw, and salt spray erosion, and can be laid underground, in the open air, or in pipe galleries;

• Long service life and low comprehensive operation and maintenance costs
  

  The service life under normal pressure conveying conditions is ≥50 years, no need for anti-corrosion and rust prevention, and simple maintenance. It is widely used in municipal, industrial and mining, water conservancy, and fire-fighting systems.
