Precision steel pipe is a high-precision steel pipe material that has been processed by cold drawing or hot rolling. Because the inner and outer walls of the precision bright pipe have no oxide layer, withstand high pressure without leakage, high precision and high finish, cold bending without deformation and flaring, flattening without cracks. and other advantages, so it is mainly used in the field of automobile manufacturing.
Here is a brief introduction for you:
One: What is seamless steel pipe? Seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The specification of the seamless steel pipe is expressed by the nominal diameter. The nominal diameter is different from the actual one. According to the steel quality, it is divided into ordinary and high-quality carbon structural steel (q195, q215a~40), alloy structural steel (q345, 20cr, 40cr, 20crmo, 30-35crmo) ), heat-resistant steel (460, 490, 510s, 655-1, 65mn), stainless steel (1cr18ni9, 0crl8ni9ti).Seamless steel pipes have hollow sections and are used in large numbers as pipes for transporting fluids. The representative material is 20 and so on.
Two: What is precision light control?
In layman’s terms, a thin-walled steel pipe with a smooth inner hole and a uniform wall thickness is called a precision bright pipe fitting.
Three: What are the uses and characteristics of seamless square and rectangular tubes.
1. The seamless square tube is used as a fluid transmission pipeline such as water and gas pipes;
2. The boiler is used as the exhaust pipe of the steam tube heating furnace;
3. Conduit for petroleum geological drilling;
4. Cracking tubing for petrochemical industry, etc.
