Currently, large diameter stainless steel seamless pipe manufactured in our country are mainly hot-rolling large diameter stainless steel seamless pipe and thermal expansion large diameter stainless steel seamless pipe. Thermal expansion stainless steel seamless pipe includes non-national standard large diameter stainless steel seamless pipe sizes. There are different large diameter stainless steel seamless pipe sizes even the types of pipes are the same. However, the different sizes of large diameter stainless steel seamless pipes have the same feature that the density is low but the contraction is strong. Cross-rolling method, along with drawing method is used to expand pipe diameter of the seamless pipe.
Another type of large diameter stainless steel seamless pipe, hot-rolling large diameter stainless steel seamless pipe is made by hot rolling. The process of large diameter stainless steel seamless pipe manufacturing is not complex. After inspection and simple cleaning on the surface of the steel material, solid tube will be cut into the desired length. Center on the perforation end of the tube and then the tube can be sent to the furnace to heat. Punch the tube and at the same time the tube rotates and moves forward continuously. Gradually cavity capillary is formed. Then the stainless steel tube should be sent to plug for continuing rolling. Finally, thickness of the wall can be sized by the sizing device.
Large diameter stainless steel seamless pipe sizes are different and all sizes of pipes need to be cleaned when put into use. In the process of manufacturing, storage, transportation and installation, rust, welding slag and oil rust inhibitor coating on the pipeline for the anti-corrosion purpose will be produced. Dust, sand, cement and insulation materials on the large diameter stainless steel seamless pipe will greatly affect the working performance of the pipe. That is why cleaning is important. After cleaning, the clean metal surface is going to form a dense layer of chemical passivation membrane. Passivation membrane can effectively prevent dirt again and can effectively protect equipment. The life of the large diameter stainless steel seamless pipes can be ensured by cleaning pipes.
