Alloy steel pipe 2




Fine seamless steel tube classification
Fine seamless steel pipes are divided into ordinary and hydraulic. Generally speaking, hydraulic is more durable than ordinary, and it is more convenient to use. Let's take a look at the relevant types and clarifications of these two types of fine seamless steel pipes today. :
Ordinary fine seamless steel pipes are generally used in machines or systems that have no special requirements for precision and pressure resistance of fine seamless steel pipes. Hydraulic fine seamless steel pipes are generally required to use seamless fine seamless steel pipes with high accuracy and high pressure resistance.
At present, the fine seamless steel pipes used in hydraulic systems are mainly stainless steel seamless pipes, ordinary seamless fine seamless steel pipes, DIN2391 high-precision hydraulic fine seamless steel pipes. Although stainless steel seamless pipes have superior mechanical properties, they are expensive The accuracy is low and it has not been widely used. The ordinary seamless fine seamless steel pipe is widely used, but its mechanical properties are poor and the accuracy is low. Before use, it usually goes through a series of welding, test installation, pickling, alkaline washing, water washing, long-term oil stringing, testing Leakage, complicated procedures, time-consuming, unreliable materials, and has not been able to completely remove the residue in the pipe, which has become a major hidden danger of the entire hydraulic system at any time. According to statistics, 70% of the faults in the hydraulic system are caused by this reason.
