Shengyang’s perforated steel strip heat-resistant polyethylene composite pipe

The perforated steel strip polyethylene composite pipe is a perforated pipe welded by cold-rolled steel strip as the reinforced frame, and the composite pipe of composite thermoplastic plastics. Due to the introduction of the reinforced frame, the compressive strength of the pipe is significantly improved. Different types and grades of thermoplastics are used. Can produce composite pipes for different purposes The perforated steel strip plastic pipes produced by the company are divided into several uses: water supply, buried gas, hot water, chemical industry and special use.
Water supply
The perforated steel belt plastic composite piping system for water supply is made of imported PE80 or PE100 grade materials, manufactured in accordance with corporate standards, and has good weldability, environmental stress cracking resistance and rapid cracking resistance, and its performance indicators exceed pure PE water supply The performance index of the tube.
·Long service life, up to 50 years under normal conditions.
·Good sanitation, solved the problem of secondary pollution of drinking water, standard code: GB/T37263- 2018
·The inner wall is smooth, the water flow resistance is small, and the head loss is 30% lower than that of the steel pipe.
·Light weight and easy to carry.
·Convenient construction, simple welding process, and low overall project cost. The color of the pipe is white, black or the color agreed upon by both parties.
The perforated steel belt plastic composite piping system for gas uses imported PE80 or PE100 materials, manufactured in accordance with corporate standards, with good weldability, environmental stress cracking resistance and rapid cracking resistance, and its applicable performance indicators exceed pure PE Gas pipe.

Shengyang’s perforated steel strip heat-resistant polyethylene composite pipe
The perforated steel belt heat-resistant polyethylene prefabricated insulation pipe is a new type of heating pipeline, which is composed of a working pipe (including pipe fittings), a polyurethane rigid foam plastic insulation layer, and a polyethylene protective shell. Because the three become one body and are directly buried in the soil, the thermal expansion stress caused by the temperature change of the inner tube is transferred to the outer protective tube through the polyurethane insulation layer, and the soil friction force received by the outer protective tube is also transferred to the working tube through the polyurethane insulation layer. Use the friction of the soil to limit the thermal elongation of the pipe. This requires polyurethane to have a certain degree of compressive and shear strength in addition to its thermal insulation function.
