The Processing of Seamless Steel Pipe (2)

 Seamless steel pipe plastic coating treatment: After polishing, use oxygen and C2H2 to heat the pipe mouth on the outside of the pipe until the internal plastic layer is melted, and then the skilled worker will evenly apply the prepared plastic powder to the pipe

mouth. Note that it must be applied in place, and the flange shall be painted above the water stop line. In this process, the heating temperature should be strictly controlled. If the temperature is too high, bubbles will be generated during the plastic coating process. If the temperature is too low, the plastic powder will not melt completely during the plastic coating process. The above conditions will produce plastic after the pipeline is put into use. The phenomenon of layer shedding will eventually corrode and damage the seamless steel pipe part of the pipeline.
