Advantages of Precision Galvanized Steel Tubes:
- Galvanized Hydraulic Tube: Improves corrosion protection and extends the service life of seamless steel pipes. The galvanized layer will not be affected when the pipe is bent.
- Phosphated Hydraulic Tube: Phosphated steel pipe can improve coating adhesion and facilitate painting. At the same time, it can prevent the pipe surface from rusting due to oxidation or contact with corrosive media.
Why Seamless Hydraulic Tubes is Cold Drawn or Cold Rolled?
The main purpose of cold drawing or cold rolling is to further improve the precision, strength and surface quality of seamless precision carbon steel hydraulic tubes through plastic deformation process.
Therefore, seamless galvanized steel tubes have higher dimensional accuracy, surface quality and mechanical properties.
Solid seamless precision steel tubes can be better used in hydraulic and pneumatic systems. As well as precision machinery and engineering machinery and other fields.
