Heat treatment is one of the important processes in the manufacture of mechanical parts and moulds. Generally speaking, it can guarantee and cold-rolled precision bright steel pipe a variety of properties, such as wear resistance, corrosion resistance. The microstructure and stress state of the billet can also be used for various cold and hot working processes. Precision cold drawn steel tube edited precision cold drawn steel pipe is a seamless steel tube product, adopting cold drawing technology.

我国钢管表观消费量806.9万，比上年增长42.62万，比上年增长5.62%，比上年增长15.45%下降9.83个百分点，钢管表观消费增长速度更高。产量超过0.18个百分点，表明整体产销处于相对稳定的态势。坚定不移地走自己的路。中国人不怕，也能应付各种各样的挑战

Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管（GB/T8162-2008）是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管（GB/T8163-2008）是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度，尺寸精度高，越来越受到客户的青睐。
