What is seamless precision tube
Seamless precision tubes are a type of high-precision steel tube material obtained by cold drawing or hot rolling. The inner and outer walls of the tubes have no oxide layer, can withstand high pressure without leakage, and have the remarkable characteristics of high precision, high finish, no deformation during cold bending, and no cracks during expansion and flattening. This type of steel tube has a light weight when the bending and torsional strengths are the same. It is an economical cross-section steel and is widely used in many industrial fields.
The production process of seamless precision tubes usually includes cold rolling or hot rolling. The specific process may involve multiple links such as round steel perforation, pickling, cold rolling, sawing, bundling, etc. These processes ensure the high precision and high finish of the steel tubes and meet the needs of precision manufacturing.
Seamless precision tubes are made of a variety of materials, including 10#, 20#, 35#, 45#, etc. These materials have different chemical compositions and mechanical properties and can be selected according to specific usage requirements.
The application range of seamless precision tubes is very wide. In the fields of hydraulic systems, injection molding machines, hydraulic presses, shipbuilding, EVA foaming hydraulic machinery, etc., seamless precision tubes have become the preferred material due to their high precision, high strength and good corrosion resistance. Especially in the automobile manufacturing industry, seamless precision tubes are widely used in key parts such as engine components, chassis systems, fuel systems, etc., ensuring the safety and stability of automobiles. In addition, seamless precision tubes also play an important role in military industry, diesel engines, internal combustion engines, air compressors, construction machinery, agricultural and forestry machinery and other industries.
