For ERW steel pipe, like carbon steel pipe, if you need to do some hot coil for it during the process of steel strip, you need to pay high attention to the hot coil inspection during the production process.

There are five aspects we need to notice during the production.

First of all, supplier name, contract number, grade of steel pipe, heat situation, coil number, and specification should be on the inspection list for us.

Then, for the store question, we should store them with the same specification and heat number.

Of course, inspecting the workmanship would be an important step for us, like the surface checking, defects finding and so on.

What’s more, hot coil’s chemical composition and mechanical properties checking would take an important role during the whole production process.

Finally, quality check after the hot coil.
