DOM Welded Carbon Steel Pipe EN10305-2 for Hydraulic Steel Tubing E155, E195, E235 E275, E355
Size range: O.D.:6-420mm W.T.:1-50mm L:max12000mm
Applications: for Auto Industry/ Machinery Use/ Oil Cylinder Tube/ Motorcycle Shock Absorber/
Auto Shock Absorber/ Inner Cylinder/ Telescopic Cylinders/ Jack Lifting System/ Hydraulic Cylinders
Appearance:
The internal and external surface finish of the tubes is smooth, while the Weld Seam is somehow not visible or tangible.
The ID surface with roughness Ra≤4μm, the best ID smoothness we could reach Ra≤0.8μm
The inner surface can be measured and reported if this is requested by the purchaser before PO.
Supplying Steel Grade:
E155, E195, E235 E275, E355
Delivery Condition:
