Product Description

EN10305-4 E215 E235 E355 Hydraulic and Pneumatic Seamless Cold Drawn Tubes


Standard: EN10305-4      Seamless Cold Drawn Tubes for  Hydraulic and Pneumatic Systems                            
Steel tubes for precision applications.Technical delivery conditions     

Applications:   for hydraulic and pneumatic power systems              

Size range: O.D.:6-80mm     W.T.:0.5-12.5mm      L:  max12000mm                  


Manufacturing Process:

Steelmaking process:

The steelmaking process is at the discretion of the manufacturer

Steels are fully killed.


Tube manufacturing and delivery conditions:

The tubes are manufactured from hot finished seamless tubes by cold working.

Cold working is also applicable when actual production is needed.

Tubes are delivered in the delivery condition +N , means that after the final cold drawing operation, the tubes are normalized in a controlled atmosphere.


Tube apperance:

Both internal and external surface finish of the tubes smooth after cold forming as well as after Normalized Heat treatment,  Surface quality would be without ridges, dents or shallow grooves.

The tube have smooth outer and inner surfaces with a roughness Ra≤ 4μm

Areduced roughness of Ra ≤2μm is workable for inner surface, the best ID roughness we could reach 0.4-0.8 μm only by cold drawing.
