The use environment of stainless steel seamless pipes has relatively high requirements on steel. With the continuous improvement of production technology, new processes or new materials are now used to produce high-quality products for users.
As a manufacturer, it is imperative to control the quality of stainless steel seamless pipes, otherwise, the quality of the products will not be uniform, and the sales and use will not be well developed. Reasonable control of every detail in the production process. Details determine success or failure, pay attention to production details, and comprehensively reflect the quality of stainless steel seamless tubings. Plan the quality control of the product, so that the production becomes regular. The products that should not be produced are divided into more than a dozen grades. A lot of products that are good and not bad are not allowed to exist, and production must produce high-quality products.
The roughness of the stainless steel seamless tubing has different effects on the coating of parts, heat transfer and circuit resistance, reflecting surface working ability and radiation source characteristics, frictional resistance of liquid and steam, and commodity circulation of conductor surface current. The roughness of the stainless steel seamless pipes affects the wear resistance of parts. The less smooth the surface, the smaller the total area of reasonable contact between the mating surfaces, the higher the air pressure and the faster the wear. Roughness affects the reliability of the mutual matching characteristics. For overfitting, the less smooth the surface, the more likely it is to wear, so that the gap will gradually widen over the course of the work.
The roughness of the stainless steel seamless tubing affects the fatigue limit of the part. The surface of non-smooth parts has large valleys, which are as sensitive to stress as groove gaps and cracks, thus affecting the fatigue limit of parts. Roughness affects the corrosion resistance of a part. According to the external economic trough of the surface layer, the non-smooth surface is easy to allow corrosive gas or liquid to penetrate into the inner layer of the metal material, causing surface corrosion.
The roughness of the stainless steel seamless pipe affects the tightness of the part. The middle of the non-smooth surface cannot be in close contact, and the steam or liquid leaks according to the gap between the surfaces. Roughness affects the contact bending stiffness of a part. The contact bending stiffness is the working ability of the fusion surface of the part to resist contact deformation under the action of external force. The bending stiffness of the device is largely determined by the contact bending stiffness between the parts.
Affect the measurement accuracy of stainless steel seamless pipe parts. The measured surface of the part and the roughness accurately measured by the measuring instrument will directly affect the accuracy of the precise measurement, especially in the precision measurement. Stainless steel sanitary pipes and stainless steel welded pipes also need to be paid attention to in the process of use.
