China supplier QSTE700TM welded square pipe round cold bending carbon steel tube

Quality control of QSTE700TM welded square pipe

1. Material selection: Select suitable materials, such as low alloy steel, stainless steel, etc., to ensure good tolerance and toughness in low temperature environment.

2. Heat treatment: Through the heat treatment process, such as normalizing, quenching and tempering, the pipe is tempering treatment, improve its structure and performance, and improve the resistance to low temperature.

3. Material alloying: Through the addition and allocation of alloying elements, adjust the composition of the material to obtain better low temperature performance. For example, adding appropriate alloying elements to carbon steel, such as chromium, nickel, etc., can improve its low temperature resistance and corrosion resistance.

Specification:

Technical advantage:
