Step three-inspecting the workmanship of the hot coil for a steel pipe

We’ve discussed the main steps for the inspections of hot coil for a kind of ERW steel pipe. And here we would talk the step three step by step. Under this situation, you would figure the process more clearly.

Details for workmanship of the hot coil:

Surface of the steel pipe would be an important point. We need to keep the surface clean and well condition.

Defects checking would be the step two for workmanship text. From cracks, fold, scar, blister and inclusion, we should check them out before delivery.

Chemical components’ text would be necessary. Is it the steel sheet containing the dents, gouge, score or other factors would affect the quality of steel pipe.
