What are the differences between precision pipes and seamless steel pipes?

The following are the main differences between precision tubes and seamless tubes:Different manufacturing processes: Precision tubes are a type of medium to high precision cold drawn seamless tube. They are made by continuously deforming round steel billets in a cold state, and then undergoing several precision reduction, fine shaping, and high annealing treatments to produce the tube material. Seamless pipes, on the other hand, are made by accurately perforating steel billets in a hot state and then subjecting them to multiple hot rolling or cold drawing processes.

Different production standards: There are also differences in production standards between precision tubes and seamless tubes. Generally speaking, the production of precision tubes is managed according to the GB/T3639-2009 standard, while seamless tubes are produced according to the GB8162-2008 standard.

Different application scenarios: Precision tubes and seamless tubes also have differences in application scenarios. The application fields of precision tubes are more extensive, and they are usually used to manufacture high-precision mechanical parts, instruments, electrical equipment, railway vehicles, and other fields. Seamless pipes are commonly used in fields such as petroleum, chemical, aviation, aerospace, nuclear industry, and food processing.

Physical performance differences: From a physical performance perspective, precision tubes and seamless tubes also have certain differences. Compared to seamless pipes, precision pipes have higher dimensional accuracy and smoothness, while also having relatively higher strength. Due to its more refined production process, the surface quality and internal composition of precision tubes are more stable than seamless tubes. Seamless pipes are relatively more convenient and have lower costs.
