Because the pipeline internal corrosion caused by gas leaks, explosions occupies a large proportion of the pipeline after doing inner coating can effectively suppress the occurrence of internal corrosion, thereby improving pipeline safety. The other hand, the level of efficiency of gas pipeline transmission and distribution projects in the pipeline is a measure put into operation one of the main symbol of good and bad, and pipeline efficiency and pipe wall roughness to some extent.
The organic coated steel pipes for the surface- coating with excellent corrosion resistance, chemical stability and good molding properties. Steel substrate with high mechanical strength, impact resistance, resistance to bending. The combination of organic coatings and steel focused on the advantages of both. Applications in the oil industry drill drilling organic coatings, containing hydrogen sulfide, salt, a very high temperature and pressure operating under poor working conditions, the actual use of the drill pipe is subsequently proved that organic coatings with good corrosion resistance, its service life than the non- coated with organic coatings increased by 2 to 3 times. Organic coating steel pipes are used than non- coated with organic coatings life of the pipeline increased by 3 to 4 times. When the organic coated steel pipes for laying in the ground, due to the presence of the coating, forms a good insulating layer, weakening the stray current corrosion. Organic coating smooth surface smooth, easy to breed bacteria and mold, wax effectively prevent corrosion, fouling, avoid bacterial corrosion, corrosion under the scale of production.
