CBIES harnesses the cutting-edge technology of three work station drawing machines to enhance production efficiency and minimize material wastage. Our precision steel tubes, crafted through this process, boast an array of superior attributes: impeccable dimensional accuracy, exceptional tensile strength, outstanding inner surface smoothness, and remarkable straightness.

The interior surface roughness is meticulously controlled within Ra≤0.4μm, ensuring a pristine finish. The outer diameter tolerance is maintained at ±0.03mm for precise specifications, while the internal surface roughness consistently remains under Ra < 0.4μm. Additionally, the tube straightness is guaranteed to be no more than 0.5 mm/meter, reflecting our commitment to unparalleled quality standards in every aspect of our product's performance.

The production standard conforms to EN,DIN,ASTM,JIS,GB. The outer diameter is 8-127mm.
