How to reduce carbon steel welding flange wear?

December 25, 2018


How to reduce the wear of carbon steel flat welded flange, we should first understand what the reasons for carbon steel flat welding flange wear? The tube rotates in the barrel, and the friction between the material and the two causes the wear surface of the tube and the barrel to gradually wear out: the diameter of the tube gradually decreases, and the diameter of the inner hole of the barrel gradually increases. In this way, the fitting diameter gap between the tube and the barrel increases slightly with the gradual wear of the two. This phenomenon in turn increases the residence time of the material in the barrel, causing the material to decompose. In the case of polyvinyl chloride, the hydrogen chloride gas generated by the decomposition enhances the corrosion of the pipe and the barrel. If calcium carbonate and glass fiber fillers are present in the material, the wear of the pipe and the barrel can be accelerated. Because the material is not plasticized uniformly, or there is metal foreign matter mixed into the material, so that the tube torque torque suddenly increased, this torque exceeds the limit of the strength of the pipe, so that the pipe is broken. This is an example of unconventional accident damage that can affect wear.
1, the twisted pipe fittings should be considered according to the actual inner diameter of the barrel, according to the normal gap with the barrel gives the deviation of the diameter of the new pipe to manufacture.
2. After the thread surface with reduced diameter of worn pipe is treated, it is thermally sprayed with a wear-resistant tungsten carbide alloy and then ground to size.
3. Wear-resistant tungsten carbide alloy is welded on the threaded part of the wear pipe. According to the degree of wear of the pipe is 1~2mm thick, then the pipe is ground to size. This wear-resistant tungsten carbide alloy consists of C, Cr, Vi, Co, W, and B, which increases the resistance to wear and corrosion of the pipe.
4, repair the bottom diameter of the pipe as hard chromium plating treatment method, chromium is also wear-resistant and anti-corrosion metal, but the hard chromium layer is relatively easy to fall off.
