Why Should 304 Stainless Steel Pipe Be Polished?

304 stainless steel pipes are often used in sanitary ware, kitchen utensils, food production, etc., and are used in large amounts. Some users require not only dimensional accuracy, but also surface accuracy. However, in the process of processing, there may be a slight deviation in the surface spacing, and the surface of the pipe is not smooth, which is difficult to detect with the naked eye. This is because many informal manufacturers are negligent, do not pay attention to work, and do not strictly control the products. When the finished product is produced in the later stage, a series of problems and serious consequences are caused. Therefore, it is necessary to polish the 304 stainless steel pipe at this time.

The polishing process is the process of cutting the surface of the stainless steel welded pipe. Using light equipment, the light material makes it rubs against the steel pipe surface to achieve the polishing treatment of the surface. The light is also divided into inside and outside. The existing outside light is to use different thicknesses of gauze or linen to carry out the polishing process in turn, and the inner light is to use a plastic grinding head to reciprocate or select the movement inside the 304 stainless steel pipe to cut the inside of the steel pipe.

The polished pipe will be very smooth in appearance, easier to clean and maintain, and an invisible protective film will be formed on the surface of the polished steel pipe, which can prevent the surface of the pipe from being corroded, not easy to scale, and can be used as a whole The service life will be longer than that of the unpolished 304 tubes. After polishing, the product has good stability, while the product without polishing will be rougher and easier to wear.

In addition, 304 stainless steel tubes that have not been polished are more likely to penetrate the inner layer for corrosive gases or liquids, resulting in shortened service life and poor sealing. Due to the uneven surface during measurement, the accuracy of the product during measurement There are large errors.

And the roughness of the surface of the stainless steel 304 tube has different degrees of influence on its thermal conductivity, reflection ability, etc., and the smaller the effective contact area between the mating surfaces, the greater the pressure, and the faster the wear will be. Therefore, the surface roughness of stainless steel pipes must be strictly controlled, otherwise, the consequences will be disastrous.

Why should 304 stainless steel pipe be polished? Polishing is not only to improve the appearance of the surface but also to improve its performance, such as durability, corrosion resistance, etc.
