The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.
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。
