During the processing of stainless steel special-shaped pipes, there may be slight deviations in the spacing on the surface, and there may be unevenness on the surface of the pipe. This unevenness is difficult to detect with the naked eye. Many irregular manufacturers do not pay attention to their work due to negligence. quality control. When the finished product is produced in the later stage, it will cause a series of problems and cause serious consequences. What effect will the rough surface of the stainless steel special-shaped pipe have on the finished product?
1. Product stability
For a clearance fit, the rougher the surface, the easier it is to wear, causing the clearance to gradually increase during the production of the finished product.
2. Corrosion resistance of finished products
The rough surface makes it easy for corrosive gases or liquids to penetrate into the inner layer through the micro valleys on the surface, causing corrosion.
3. The sealing of the finished product
Rough surfaces do not allow a tight fit, and gas or liquid can leak through the gaps between the contact surfaces.
4. Tthe measurement accuracy of the finished product
The surface roughness of the measured surface of the part and the surface measured by the measuring tool will directly affect the measurement accuracy, especially in precision measurement. In addition, the surface roughness of the stainless steel profiled tube will have different effects on the coating of the part surface, thermal conductivity and contact resistance, reflectivity and radiation properties, resistance to liquid and gas flow, and current flow.
5. Wear resistance of parts
The rougher the surface, the smaller the effective contact area between the mating surfaces, the greater the pressure and the faster the wear.
Therefore, the surface roughness control of stainless steel special-shaped pipe must be very strict, otherwise the consequences will be disastrous. When we are looking for a manufacturer, we must choose a manufacturer with a professional quality control system, so that the product quality is more guaranteed.
