Seamless steel pipes continue to develop during the entire development trend, and the total number of manufacturers and commodities continues to increase. Due to the large number of seamless steel pipe factories and the relatively large total output in the sales market, many problems have appeared during the entire development trend, among which quality problems and many drawbacks are more typical. In addition, the overproduction of seamless steel pipes is serious, and the development trend of the intermediate field is relatively limited, and the future will also face huge challenges. In the process of the whole development trend, the following problems are mainly encountered:

Seamless steel pipe thread connection process1. The production process of seamless steel pipes can be divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled seamless steel pipes is generally more complicated than that of hot-rolled. The tube billet must first underg
