The steel wire mesh skeleton polyethylene composite pipe has the common characteristics of anti-corrosion, non scaling, smooth and low resistance, insulation without wax deposition, wear resistance, and lightweight plastic pipes. Its unique structure also creates the following features:

Steel wire mesh skeleton polyethylene composite pipe(1) Good creep resistance and high long-lasting mechanical strength

Due to the creep of plastics at room temperature and under stress, and brittle fracture under high persistent stress, the allowable stress and pressure bearing capacity of pure plastic pipes are very low (generally within 1.0Mpa). The mechanical strength of steel is about 10 times that of thermoplastic, and it is very stable and does not creep within the temperature range of plastic use. After compounding the mesh steel wire skeleton with plastic, the steel wire mesh skeleton can effectively restrain the creep of plastic, greatly improving the durability strength of the plastic itself. Therefore, the allowable stress of steel wire mesh skeleton polyethylene composite pipes is twice that of plastic pipes.

Steel wire mesh skeleton polyethylene composite pipe(2) Good temperature resistance performance

The strength of plastic pipes generally decreases with increasing temperature within its operating temperature range, and for every 10 ℃ increase in temperature, the strength decreases by more than 10%. Due to the fact that about 2/3 of the strength of the steel wire mesh skeleton polyethylene composite pipe is borne by the steel wire mesh skeleton, the degree to which its strength decreases with increasing use temperature is lower than that of any pure plastic pipe. The experimental results show that for every 10 ℃ increase, the strength of the steel wire mesh skeleton polyethylene composite pipe decreases by less than 5%.

Steel wire mesh skeleton polyethylene composite pipe(3) Rigid, good impact resistance, good dimensional stability, and moderate flexibility, combining rigidity and flexibility

The elastic modulus of steel is usually about 200 times that of high-density polyethylene. Due to the strengthening effect of the steel wire mesh skeleton, the rigidity, impact resistance, and dimensional stability of the steel wire mesh skeleton polyethylene composite pipe are superior to any pure plastic pipe. At the same time, due to the fact that the mesh steel skeleton itself is a flexible structure, the composite pipe also has a certain degree of flexibility in the axial direction. Therefore, this pipe material has the characteristics of combining rigidity and flexibility, and exhibits excellent adaptability in loading, unloading, transportation, installation, and reliability in operation. Installation on the ground can save the number of supports and reduce costs; Underground installation can effectively withstand sudden impact loads caused by settlement, slippage, vehicles, etc. Small caliber pipes can be bent appropriately and arranged in a serpentine or undulating manner according to the terrain, saving pipe fittings.
