Carbon Steel Pipe Precision Tube manufacturer

Precision steel pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of the precision steel pipe have no oxide layer, withstand high pressure without leakage, high precision, high finish, no deformation after cold bending, flaring, Flattened without cracks, etc., so it is mainly used to produce products for pneumatic or hydraulic components, such as air cylinders or oil cylinders.
Manufacturer of Carbon Steel Pipe Precision Tube
The precision stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipe and the successful development of new reliable, simple and convenient connection methods make it have more irreplaceable advantages of other pipes, and the application in engineering will become more and more. In many cases, stainless steel pipes are more advantageous, especially thin-walled stainless steel pipes with a wall thickness of only 0.6 to 1.2 mm are used in high-quality drinking water systems, hot water systems and water supply systems that put safety and hygiene first. It has the characteristics of safety, reliability, sanitation and environmental protection, and economical application. It has been proved by engineering practice at home and abroad that it is one of the best, new, energy-saving and environmentally friendly pipes in the water supply system. It is also a very competitive water supply pipe. comparable effect.
