45# precision tube manufacturer

Precision steel pipe is a high-precision steel pipe material that is processed by cold drawing or hot rolling. r3 Precision steel pipes are mainly used to produce pneumatic or hydraulic components because they have no oxide layer on the inner and outer walls, can withstand high pressures without leakage, are highly precise, and have high smoothness.
r3 has the advantages of no deformation during cold bending, no cracks in flaring or flattening, etc.
r3 products, such as cylinders or oil cylinders, can be seamless pipes or welded pipes. The chemical composition of precision steel pipe
r3 includes carbon, silicon, manganese, sulfur, phosphorus and chromium.

r3 precision steel pipes have no oxide layer on the inner and outer walls, can withstand high pressure, no leakage, and high Precision, high smoothness, no deformation in cold bending, no cracks in expansion and flattening, surface anti-rust treatment, widely used in precision steel pipes for hydraulic systems, precision steel pipes for injection molding machines, precision steel pipes for hydraulic presses, steel pipes for shipbuilding, and foaming Hydraulic machinery, seamless steel pipes for precision hydraulic cutting machines, shoemaking machinery, hydraulic equipment, high-pressure oil pipes, hydraulic oil pipes, ferrule joints, steel pipe joints, rubber machinery, forging machinery, die-casting machinery, engineering machinery, concrete pump trucks High-pressure steel pipes are used in sanitation vehicles, automobile industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, air compressors, construction machinery, agricultural and forestry machinery, etc. It can completely replace imported precision steel pipes of the same standard
r3 automobile, Mechanical accessories and other machinery that have high requirements on the precision and smoothness of steel pipes. Currentusers not only have high requirements for precision, but also have high requirements for smoothness. Because precision and brighthave high precision and can maintain tolerances within wires, many machining processes In order to save the loss of labor, materials and time, the materials used by users will be slowly transformed from or round steel to precision bright seamless steel pipes
