With the continuous development of our country's economy, the state has been developing the pressure blasting machine industry. Long oil and gas pipelines are an important way to ensure power. During the anticorrosion construction of oil pipelines, the disposal of the appearance of spiral steel pipe pressure blasting machines is a decision on pipeline anticorrosion. One of the key elements of using longevity.
In order to achieve the desired rust removal effect when selecting a pressure type sand blasting machine, the abrasive should be selected according to the external hardness of the spiral steel pipe, the original degree of rust, the required surface roughness, and the type of coating. About single-layer epoxy, two-layer, With three layers of polyethylene coating, a mixed abrasive of steel grit and steel shot is more easily used to achieve the desired rust removal effect.
Pressure sand blasting machine is a condition for the strong connection between the anti-corrosion layer and the steel pipe. The life of the anti-corrosion layer depends on factors such as coating type, coating quality and construction environment. About 50 percent.
Therefore, the requirements for the appearance of steel pipes in accordance with the standards for anticorrosive coatings should be strictly followed, and continuous exploration and conclusions should be made to continuously improve the disposal methods for the appearance of steel pipes.
