The Processing of Making ERW Tube in Mill
Steel tube begins as flat steel strip that has been opening to the right width for the end tube measure. It is then gone through a progression of rolls that frame it into a round tube.

This warmth is the thing that welds the two steel edges together. Utilizing this strategy will create a solid weld that is similarly as solid as or more grounded than the first steel. ERW Tube
