Precautions for steel pipe production

    R&D center and production center would have discussion for the precautions measures during the steel pipe’s production, so that they would supply high quality steel pipe from seamless steel pipe to welded steel pipe like ERW steel pipe for customers.

    First of all, suppliers should pay high attention to joint. In order to make no wrong side or less than a range like the general error is less than or equal to 8%, we should make strategies before production.

    What’s more, rightful penetration depth is another parameter for manufacturers. It is important to make insure there is no cracking, no burning phenomenon after welding.

    Additionally, for final external welding quality, we should get the continuous weld and good shape.
