1.Overview of Precision Steel Pipe

    Precision steel pipe is a high-precision, high-brightness seamless steel pipe produced by cold drawing or hot rolling. There is no oxide layer on the inner and outer walls of the precision steel pipe, and it has the advantages of being able to withstand high pressure without leakage, cold bending without deformation, and flattening without cracks. Precision steel pipes are widely used in the production of products for pneumatic or hydraulic components, as well as in the manufacture of precision mechanical parts. Main production grades: St35.8, St42, St45, St52.

3.Characteristics of precision steel pipes

1.The outer diameter is smaller.

    Due to its light weight, precision steel pipes can be easily transported and constructed, and the cost can be manipulated. Due to its excellent corrosion resistance and industrial equipment performance, thin-walled stainless steel pipe can only be about one-third of the thickness of galvanized steel pipe. Therefore, the net weight of precision steel pipes is greatly reduced, and the cost is also reduced, making transportation easier and installation more convenient and fast. 

2. High precision and high brightness.

3. The cold drawn finished product has high precision and good surface quality.

    Because the surface of precision steel pipe will cause a thin protective film, which is very firm. Even if it is damaged, if there is CO2 around, it can be reshaped immediately to prevent rust. If you master the characteristics of stainless steel plate and use it properly

4. The performance of the steel pipe is better and the metal is denser.

    Precision steel pipes are used in specifications with less erosion such as tap water pipes or boiling water up to 100 ℃. Most of them do not need to worry about rust, or the reduction of inner diameter or friction expansion caused by extensive "rusty small meat spots" in galvanized steel pipes, so as to obtain water flow that is not easy to be blocked.

5. Cold bending is not deformed, flattened without cracks.

4.Application field of precision steel pipe

    Precision steel pipes are mainly used in chemical, petroleum, aerospace, food, energy, medicine, electric power, environmental protection, boiler heat exchange and other fields.
