Corrosion properties of welded steel pipe
Mar 28, 2018

T-containing welded steel pipes contain corrosion in the acidic environment when Ni is contained. In the environment containing sulfuric acid or hydrochloric acid, the higher the Ni content in the T-shaped welded steel pipe, the stronger the corrosion resistance. Under normal circumstances, corrosion can be prevented by simply adding Cr to the T-welded steel pipe. Poor condition of the strip edge is another important cause of misalignment. The effects of mass flow, heat flux, and structural parameters (the ratio of the diameter of the spiral curvature and the diameter of the T-welded steel tube diameter Dc/D) on the saturated bubble boiling heat transfer coefficient in the vertical spiral tube.

In the production of T-welded welded steel pipe, the wrong side occurs from time to time, and there are many factors that affect it. In the production practice, the steel pipe is often degraded from the wrong side. Therefore, it is necessary to analyze the causes of the wrong side of the spiral steel pipe and the preventive measures.
