The antiseptic steel pipe for oil and natural gas transportation is hundreds of kilometers long and thousands of kilometers long in engineering application.182 through different types of soil rivers and lakes due to the heterogeneity of the soil.Freezing and thawing in winter and summer.Penetration of the coating by the underground water level change, plant roots, microbial stray current complex buried conditions, such as to cause pipeline corrosion ring complex organic sulfide minerals, salt, formation water, oxygen, so buried oil gas transmission pipe pipeline anticorrosion form usually 3278 pipe corrosion, pipeline corrosion, pipeline cathodic protection, pipeline corrosion protection on the ground.Anti - corrosion coating requirements: with good soil, water, mold corrosion and construction performance.Good electrical insulation.When used in combination with cathodic protection, the anticorrosive coating should have a certain resistance to cathodic stripping strength.It has enough mechanical strength.To ensure that the coating in the handling and soil pressure under the action of no damage.It is one of the most basic methods to evenly and compactly apply the coating on the surface of the corrosion-resistant steel tube after derusting to isolate it from various corrosive media.
