Nanyang Machinery, as a manufacturer of high-frequency welded pipe units in Yangzhou, has sufficient understanding of steel pipes and other materials. Today, I will teach you how to increase the service life of steel pipes:
The coating of steel substrate is the most commonly used method, and it is also one of the best methods. Galvanizing greatly increases the corrosion resistance of steel, and also increases the sales of hot-dip galvanized square tubes, hot-dip galvanized angle steel and other products.
Because the process temperature of hot galvanizing is relatively high, the material with lower tempering temperature is easy to be annealed in the process of galvanizing, so that the hardness is reduced. In addition, the use of hot-dip galvanizing for mating parts should also consider the effect of the thickness of the coating on the mating tolerance.
Hot galvanizing is to immerse the derusted steel member into molten zinc melted at a high temperature of about 600 ℃ to attach a zinc layer to the surface of the steel member. The thickness of the zinc layer shall not be less than 65μm for thin plates below 5mm and 86μm for thick plates. So as to play the purpose of anti-corrosion. In recent years, a large number of light steel structure system in the profiled steel plate. Also more use of hot galvanizing anti-corrosion. The first process of hot galvanizing is pickling and derusting, followed by cleaning. These two processes are not complete will leave hidden dangers to anti-corrosion, so must be dealt with thoroughly.
