Causes and Cutting Methods of Slag Inclusions in Straight Seam Steel Pipes
Slag inclusions in welded steel pipes are residual slag inside the weld. Theoretically, the main causes of slag inclusions in submerged arc welded steel pipes are as follows: ① Excessive inclusions in the raw materials (including base metal, welding wire, and flux); ② Inadequate interlayer cleani...Read more -
Temperature and Lubrication Control in the Production of Straight Seam Steel Pipes
Strict temperature control is crucial during the production of straight seam steel pipes to ensure reliable welds. If the temperature is too low, the weld area may not reach the required temperature, making it difficult for the metal ends to interpenetrate and bond when most of the metal remains ...Read more -

Developed Western countries emp...Read more -
Why do precision steel pipes need pickling
1. Pickling removes oxide scale (iron oxide scale) from precision steel pipes. During hot rolling or annealing, a hard oxide scale (FeO, Fe₂O₃, Fe₃O₄) forms on the surface of precision steel pipes. This scale is very difficult to remove mechanically and affects the surface quality of the precisio...Read more
