Causes of wear of stainless steel flat welded flange

Stainless steel flat welded flange damage will occur for some reason, usually in the inner rotation of the cylinder, the friction between the material and the flange, the working surface of the flange and the cylinder gradually friction, the diameter of the tube continues to become smaller, the diameter of the cylinder gradually increases, and gradually enters a vicious cycle, the flange and the assembly gap of the cylinder gradually increase with the expansion of friction between them.

In addition, the retention time of the material in the barrel will also increase, causing the material to dissolve, if it is polyvinyl chloride, then dissolve the chlorinated gas to enhance the corrosion of the stainless steel flat welded flange and the barrel, such as calcium carbonate and glass fiber materials, can speed up the damage of the flange and its barrel.

When the stainless steel flat welded flange manufacturer welds the flange, the material is not plasticized evenly, or there is a metal foreign body mixed with the material, and the rotating torque force of the flange suddenly expands, and the torque exceeds the strength of the pipe, making the flange twist.

Solutions to wear and tear

The wear of stainless steel flat welded flange needs to be solved with different countermeasures. After operating the surface of the damaged flange diameter reduction line, a wear-resistant tungsten carbide alloy is sprayed with a thermoplastic and then ground to a conventional size. The wear-resistant tungsten carbide alloy can also be fixed on the threaded part of the damaged flange

According to the wear on the flange, the thickness is 1-2mm, and then the conventional size. Damaged flanges can be repaired by electroplating hard chromium. The above method is a very effective treatment method for stainless steel flat welded flanges.

Stainless steel flat welded flange is corroded

When the stainless steel flat welded flange is corroded, the traditional welder maintenance, obviously for many manufacturers do not have this standard, especially the original corrosion parts, there are also some highly corrosive liquids, mostly corrosive liquid damage, if the operator is not particularly professional, it is not easy to try.

If there is high corrosion, it is still proposed to replace the parts, because the price of the general flange is not particularly expensive, and there is not a lot of money to buy one. Even if the quick repair operation is done, the effect after repair is still unknown, and finally change new parts.

In addition, another carbon nanotube polymer production flange, flange has good corrosion resistance, especially strong impact resistance, repair procedure is simple

If the internal flange used in the enterprise is often corroded, it may also change the production of industrial carbon nanopolymer flanges.
