  • Cold Drawn Seamless Steel TubesOur cold drawn seamless steel tubes, sometimes abbreviated as CDS tubes, meet all the requirements of DIN and EN standards, and they are manufactured from high quality carbon steel through cold drawing and bright heat treatment (NBK). This product is further divided ...
  • Cold Rolled Seamless Steel TubesThe cold rolled seamless steel tube is a precision steel tube, and it is made from cold rolled steel. This mechanical steel tubing is able to withstand high pressure without generating leakage problem, and there is no oxide layer on inner and outer surfaces.
  • High Pressure Steel Tube for Fuel InjectionThanks to the surface strengthening technique which is applied to the inner surface of tube, our fuel injection steel tubing has a high working pressure, usually over 300 bars.
    The high pressure steel tube stands out from numerous competitors because of its superior dimensional accuracy.
  • Seamless Steel Tubes for Hydraulic and Pneumatic SystemOur hydraulic tube and pneumatic tube receive bright heat treatment in a controlled atmosphere that doesn’t contain oxygen to realize the delivery condition of NBK, and the inner surface is washed by high pressure spray gun and other specialized device.

Precision Steel Tubes

As a professional China-based steel tube manufacturer, we could provide worldwide customers with various precision steel tubes including seamless precision steel tube and welded precision steel tube, and these products are fabricated through cold drawing or hot rolling process. In this regard, they are also known as cold drawn precision steel pipe or cold rolled precision steel pipe.

Feature and Application
Our product possesses good dimensional accuracy, high surface smoothness as well as excellent resistance to high pressure, and there is no oxide layer on its inner or outer surface. Moreover, cold bending, expanding and flattening treatments won’t lead to deformation and cracks.

Based on these properties, the precision steel tube is widely used to make hydraulic and pneumatic components, such as air cylinder, oil cylinder, etc.
