Design and manufacture various specifications and models of 316L stainless steel welded pipe molds-rolls and special-shaped rolls, thus forming a series of products and enjoying a high reputation in the industry. As a manufacturer of stainless steel welded pipes, our company has sufficient knowledge of stainless steel pipes and other materials. The following stainless steel welded pipe manufacturers teach you how to increase the service life of 316L stainless steel welded pipes:

Coating the steel substrate is a commonly used method, and it is also one of the better methods. Galvanizing greatly increases the corrosion resistance of steel, and also makes the sales of hot-dip galvanized square pipes, hot-dip galvanized angle steel and other products increase.

Since the process temperature of hot-dip galvanizing is relatively high, it is easy to anneal during the galvanizing process for materials with a lower tempering temperature, thereby reducing the hardness. In addition, the use of hot-dip galvanizing for mating parts must also consider the influence of the thickness of the coating on the mating tolerance.

Hot-dip galvanizing is to immerse the derusted steel member in a molten zinc melt at a high temperature of about 600 ° C to attach a zinc layer to the surface of the steel member. The thickness of the zinc layer should not be less than 65μm for thin plates under 5mm and not less than 86μm for thick plates. So as to prevent corrosion. In recent years, there have been a large number of light-weight steel structure systems such as profiled steel plates. Hot-dip galvanizing is also used to prevent corrosion. The first process of hot dip galvanizing is pickling to remove rust, then cleaning. Both of these two processes are incomplete and will leave hidden dangers to anti-corrosion, so they must be dealt with thoroughly.
