From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. standard of 09CuPTiRE-B, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

The main applications of normalizing are as follows:① For low carbon steel, standard of 09CuPTiRE-B. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

According to the economic development trend in Asia and the economic development of China, India, Japan and ASEAN, it is estimated that the steel consumption in Asia will be 1228 million tons in 2019, with a year-on-year growth of 6.6%; the standard of 09CuPTiRE-B steel demand in Asia in 2020 is predicted to be 1.241 billion tons, with a year-on-year growth of 1.1%. According to the standard of 09CuPTiRE-B economic development of Europe, it is estimated that the steel consumption in Europe will be 202 million tons in 2019, with a year-on-year decrease of 3.3%; the steel demand in Europe in 2020 is predicted to be 205 million tons, with a year-on-year growth of 1.5%.
