1.Visual inspection. Before processing, generally to do visual analysis for 3PE Anti-corrosion Steel Pipe by skilled workers. Check if the steel pipe has serious mechanical damage, heavy leather, cracks, and check the thread.
2.Pipe rust. To do heat treatment of fire inflammation for the steel pipe to remove the moisture, grease, impurities on the surface of the steel pipe.
3.After grinding, the outer surface of the steel pipe was treated two times with the micro dust treatment device.
4.Steel pipe preheating before the epoxy powder coating. According to the steel pipe diameter and feeding speed, select the appropriate temperature, but can not exceed 275 degrees.
5.Adhesive coated with polyethylene winding.
6.In the production of 3LPE Coated Steel Pipe should be fixed after cooling molding, the cooling treatment of anti-corrosion layer is carried out by circulating water pouring room.
7.Cut the retaining head, and deal with the end of the pipe with steel brush.
