Straight seam steel pipe production temperature:In the process of producing straight seam steel pipes, it is necessary to strictly control the temperature, so as to ensure the reliability of welding. If the temperature is too low, the welding position may not reach the temperature required for weldi

A. The appearance of the storage and delivery of anti-corrosion steel pipes needs to be checked as follows:①Check root by root to ensure that the surface of the polyethylene layer is flat and smooth, without dark bubbles, pits, wrinkles, and cracks, and the overall color needs to be more uniform. Th

Pretreatment of straight seam steel pipe:The non-destructive testing inside the weld is because the pipeline is an extra-large steel pipe in the water supply project, especially the steel pipe with a thickness of t=30mm is used as a pipe bridge. bending moment, so the requirements for welding are pa

In the construction sequence of steel pipe piles, we should first master all aspects of the project for comprehensive consideration and analysis, such as construction machinery, construction period, design requirements, landform environment, engineering quantity, layout, specifications, and characte
