Coal Mine
Stainless steel reinforced spiral welded pipes for gas drainage solve the problem of anti-static electricity and satisfy the requirements of the flame retardant performance of the coal mine gas pipeline; light weight and easy to carry is convenient for coal mine transportation and installation; corrosion resistance, no rust, don’t need anticorrosive processing, greatly prolonging the service life of the coal mine gas pipeline. The adoption of reinforcement of stainless steel spiral pipes enhances the pipe’s ring stiffness and reduces the cost so as to serve the gas drainage system at a lower price.
