Stainless Steel Precision Rolled Tube

Stainless Steel Tubing

Stainless Steel Precision Rolled Tube / Stainless Steel Hollow Rod

Accurate inner and outer diameter control is essential for hollow rod applications used in pneumatic, hydraulic, electric, and servo-driven systems. Compass Power Tech manufactures stainless steel precision rolled tubes, also used as stainless steel hollow rods, for cylinders, electric actuators, hydraulic actuators, servo electric cylinders, and components used in medical and food equipment.

This process helps keep inner and outer tolerances consistent, reduce diameter deviation, and improve concentricity for downstream machining and assembly. After production, every finished stainless steel precision rolled tube is inspected for appearance, dimensional accuracy, physical properties, and chemical performance to ensure reliable delivery quality.

Note: The outer surface of the stainless steel precision rolled tube can be chrome plated to improve wear resistance and service life. The standard chrome layer thickness is usually 15 µm, and the plating thickness can also be customized according to customer requirements. After chrome plating, the outer surface roughness can reach Ra≤0.2 µm.

Additional Custom Services

Cut-to-length service: Tubes can be cut according to the customer’s required working length or assembly length.
Machining service: Stainless steel precision rolled tubes can be machined according to customer drawings to reduce downstream processing work.
Outer surface chrome plating: Chrome plating can be applied to the outer surface to improve OD wear resistance and extend the service life of the tube.

Packaging and Storage

To protect stainless steel precision rolled tubes during sea freight and storage, Compass Power Tech uses anti-rust paper tube packaging. Before wrapping, anti-rust oil is applied evenly to the tube surface, and anti-rust wax is applied inside the paper tube. This protective process helps reduce corrosion risk during transportation and ensures customers receive high-quality tubes in stable, ready-to-use condition.
