Information
Jiangsu Nanyang Machinery Manufacturing Co., Ltd. specializes in designing and manufacturing various types of high-frequency welded pipe units, stainless steel precision welded pipe units, high-precision steel-plastic and stainless steel composite welded pipe units; designing and manufacturing various types of welded pipe molds – rolls and shaped rolls, thus The product has been serialized and has a good reputation in the industry. As a manufacturer of high-frequency welded pipe units in Yangzhou, Nanyang Machinery has sufficient understanding of materials such as steel pipes. Today, we teach you how to increase the service life of steel pipes:
Coating the steel substrate is the most common method and one of the best in various methods. Galvanizing greatly increases the corrosion resistance of steel, and also increases sales of hot-dip galvanized square tubes and hot-dip galvanized angle steel.
Since the process temperature of hot-dip galvanizing is relatively high, the material having a lower tempering temperature is easily annealed during the galvanizing process, so that the hardness is lowered. In addition, the use of hot-dip galvanizing of the fittings also takes into account the influence of the thickness of the coating on the tolerances.
Hot-dip galvanizing is to immerse the rust-removed steel member in a zinc solution melted at a high temperature of about 600 ° C to adhere the zinc layer to the surface of the steel member. The thickness of the zinc layer is not less than 65 μm for a sheet of 5 mm or less and not less than 86 μm for a thick plate. Thereby playing the role of corrosion protection. In recent years, a large number of profiled steel sheets in light steel structural systems have appeared. More hot-dip galvanizing is also used. The first process of hot-dip galvanizing is pickling and rust removal, followed by cleaning. These two processes are not completely harmful to the corrosion, so it must be handled thoroughly.
