?Wuxi Duorunde Steel Pipe Co., Ltd. (my answer); 20# seamless steel pipe and 20# precision steel pipe are two common steel pipe products. They have certain differences in material characteristics and scope of application. the difference. The differences between these two steel pipes will be introduced in detail below.
20# seamless steel pipe is a seamless steel pipe made of 20# steel as raw material. It has good mechanical properties and corrosion resistance. Its manufacturing process mainly includes perforation, rolling, straightening, cutting, pickling, phosphating, saponification, coating and other processes to ensure the quality and performance of the product. 20# seamless steel pipe is widely used in various mechanical parts manufacturing fields, such as automobiles, petroleum, chemical industry, etc., especially in high pressure, high temperature and other environments with good performance.
20# precision steel pipe is a precision steel pipe made of 20# steel as raw material. Its manufacturing process has gone through multiple processes and has high precision, high strength and high corrosion resistance. sexual characteristics. Compared with 20# seamless steel pipe, the manufacturing process of 20# precision steel pipe is more complex, the precision requirements are higher, and the price is relatively high. 20# precision steel pipe is suitable for various high-precision and high-demand mechanical parts manufacturing fields, such as aviation, aerospace, automobiles, etc. ?

In addition to the differences in material characteristics and scope of application, there are also differences in accuracy between 20# seamless steel pipes and 20# precision steel pipes . 20# precision steel pipe has higher precision. Its inner and outer surfaces have been processed and processed through multiple processes, with high smoothness and parallelism. It is suitable for occasions that require high-precision fit. The precision of 20# seamless steel pipe is relatively low and is mainly used for general mechanical parts manufacturing.
When selecting and using steel pipe products, the appropriate type and specifications should be selected based on actual needs and usage occasions. For the manufacturing of mechanical parts that need to withstand high pressure, high temperature and other environments, you can choose 20# seamless steel pipe; for the manufacturing of mechanical parts that require high-precision fit, you can choose 20# precision steel pipe. At the same time, attention should be paid to selecting manufacturers of steel pipe materials and manufacturing processes with good mechanical properties and reliable quality to ensure product quality and reliability.
In short, there are certain differences in material characteristics and application scope between 20# seamless steel pipe and 20# precision steel pipe. 20# seamless steel pipe is suitable for general mechanical parts manufacturing, while 20# precision steel pipe is suitable for high-precision and high-demand mechanical parts manufacturing fields. When selecting and using steel pipe products, you should pay attention to distinguishing different materials and specifications, and choose the appropriate type and specifications according to actual needs and usage occasions. At the same time, attention should be paid to selecting manufacturers of steel pipe materials and manufacturing processes with good mechanical properties and reliable quality to ensure product quality and reliability.
