Cold Drawn Seamless Steel Tubes can withstand high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., so they are mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. It uses seamless tubes.
