Hot-rolled seamless steel pipe
Hot-rolled seamless steel pipe: hot rolled is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling, and hot rolled is carried out at above the recrystallization temperature of the rolling. The process of hot-rolled seamless steel pipe: Hot-rolled ...Read more -
Seamless steel pipe detection
A seamless steel pipe is a pipe that does not have any welding seam. The seamless steel pipe will ideally be a solid metal tube with each end connected to another tube without having any welding joint. These pipes have threads either at one end or at both ends and can be threaded to the end of an...Read more -
What is cold drawn seamless steel?
Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. What is the difference between cold rolled and cold drawn? Cold drawn steel, like cold ro...Read more -
About Lead glass
Lead glass is a new type of glass, which can effectively resist radiation entering the room. Lead glass not only has the effect of anti radiation, but also has many other advantages, such as non-toxic, tasteless and anti oxidation. The luminescence of lead glass is ≥ 85%, and the lead content in ...Read more -
Classification of seamless steel pipes
Seamless steel pipe is perforated by the whole round steel, and the steel pipe without weld on the surface is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold drawn seamles...Read more -
Application of seamless steel pipe

Precision tube: a brief introduction of precision tube
If ordinary steel pipe is selected, there will be a big error between the ordered steel pipe and the received steel pipe. Even in different parts of the steel pipe, the inner diameter or wall thickness will vary greatly. But precision tubes are different. This kind of steel pipe has very strict r...Read more -
