In addition to being used for oil exploration, the emergence of oil casing can also be used as a pipeline for transporting raw materials. To enhance the quality of oil casing, every link in the production process is particularly important, especially the temperature control during the period, whic

The first may be due to the stress of the spiral seam submerged arc welded steel pipe. That is, the residual stress and welding stress after the steel pipe is formed. Secondly due to the presence of hydrogen. If the flux is not dried enough, the preheating temperature is not sufficient or the prehea

There are many reasons for the leakage of oil and gas pipelines, which can be mainly divided into three categories: corrosion perforation, fatigue rupture, and external force damage.Although taking corrosion control measures can significantly slow corrosion, it does not prevent corrosion.
