High-Precision Seamless Pipes for Hydraulic and Pneumatic Systems

Date:2025-03-08

Seamless steel pipes are essential in high-pressure hydraulic and pneumatic systems, where uniformity and precision are critical.

ID & OD Tolerances: Cold-drawn seamless (CDS) tubes achieve ±0.02 mm tolerance, ensuring leak-free performance.

Surface Roughness Control: Honed and skived roller-burnished pipes improve fluid dynamics and extend seal life in hydraulic cylinders.

High Yield Strength Steels: E355, ST52, and 4140 grades provide superior pressure resistance without excessive wall thickness.
