How should the stainless steel welded pipe 304 be used correctly for a long time? If it is used correctly, it will extend the service life of the stainless steel welded pipe 304. Coating the stainless steel welded pipe substrate is the most commonly used method, and it is also one of the better methods. Galvanizing greatly increases the corrosion resistance of stainless steel welded pipes, and also makes the sales of hot galvanized square pipes, hot galvanized angle steel and other products increase.

The stainless steel welded pipe manufacturer introduced that because the process temperature of hot-dip galvanizing is relatively high, the information on the lower tempering temperature is very simple so that it is annealed during the galvanizing process, and then the hardness decreases. In addition, the use of hot-dip galvanizing for cooperative parts must also consider the effect of the thickness of the coating on the cooperative public service.

Hot dip galvanizing is to immerse the derusted steel component in a zinc solution that melts at a high temperature of about 600 ° C to make the steel component adhere to the zinc layer. 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. Then play the role of anti-corrosion. In recent years, there has 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. The incompleteness of these two processes will leave the stainless steel welded pipe 304 with a risk of corrosion prevention, so it is necessary to deal with it completely.
