Characteristics of plastic-coated composite steel pipes for mining
Mining plastic-coated composite steel pipes have the following characteristics:
(1) Flame retardant and antistatic
The product uses polyethylene coating for mining. Its antistatic and flame-retardant components are evenly distributed on the surface and inner layer of the pipe. It meets the requirements of MT181 and is suitable for specific flammable and explosive places underground in mines.
(2) Extremely strong adhesion
After the inner and outer surfaces of the plastic-coated steel pipe are coated, bonded, and solidified, the adhesion force is 230N/10mm. It can be impacted and torn by a falling weight without damage.
(3) Corrosion resistance, not easy to scale, low fluid resistance
The pipe has strong acid and alkali resistance and corrosion resistance and is suitable for high-sulfur water in coal mines and water containing calcium, magnesium, and other ions. Due to its high surface finish and small fluid resistance, it will not adhere to scale and can reduce secondary pollution.
(4) High pressure bearing
Polyethylene powder coating has good toughness, high mechanical strength of steel pipe, and a strong ability to withstand external influences such as impact and bending.
