Production

The steel bar is pierced or drilled to create a hollow center.

Tube cold drawn process is a metalworking process to size the tube by drawing the tube through a die to required length by controlling the extensibility step by step.

Cold rolling process reduces the tube sizes across three dimensions: outside diameter, internal diameter and wall thickness.

The SRB (Skiving and Roller Burnishing) process is a precision machining method used to improve the surface finish and dimensional accuracy of hydraulic cylinder tubes.

Customized services for seamless steel tubes typically involve tailoring the manufacturing process, dimensions, materials, surface finishes, and additional treatments to meet the specific requirements of customers.
