Stainless steel seamless pipe is a long strip of steel with a hollow section and no joints around it. It is a kind of steel pipe that is resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt.However, in long-term use, stainless steel seamless pipe is prone to scale.

In order to improve the product quality of seamless pipes and eliminate spots, surface degreasing and cleaning processes are required. The components and properties of lubricants are very important for surface degreasing and cleaning.

Now due to the development of science and technology, the ordinary quenching technology of cold drawn seamless tubing has been upgraded to high-frequency quenching technology. At present, high-frequency quenching technology has been widely used.

In the whole process of welding production, 35crmo welded pipe can easily show many situations such as missing welding and misalignment. But in this case, it is more difficult to grasp the trachoma at the butt weld of the 35crmo welded pipe.

The quality of the erw steel pipe in the production determines its quality in use.In the production process of erw steel pipe, each processing is carried out at high temperature, so the heating operation is a very important process to determine the quality of the product.

The temperature specified in the quenching process of black steel seamless pipe should not be too high. Quenching at an excessively high temperature will cause various damages. In most cases, cracks will occur in the black steel seamless pipe. Therefore, black steel has no The quenching temperature of the seam tube should not be too high.
