The reason for the wrong side of the spiral steel pipe
In production practice, the steel pipe is often degraded by the wrong side and out of tolerance. Therefore, it is necessary to analyze the reasons for the misalignment of the spiral steel pipe and its preventive measures. The camber bend of the steel strip is the most importan...Read more -
The problem of uneven thickness of the anti-corrosion coating of the spiral steel pipe and the treatment method
Spiral steel pipes are mainly used as fluid pipes and piling pipes. After the steel pipes are made, if they are used for running water, they will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3pe anti-corrosion, epo...Read more -
