Product Introduction

Advantages of stainless steel seamless pipe include:

1. Corrosion resistance: Stainless steel has strong corrosion resistance, so seamless steel pipe can be used in the environment containing acid, alkali, salt and other highly corrosive substances, and has a long service life.

2. High strength: The strength of stainless steel seamless pipe is higher than that of ordinary steel pipe, so it can withstand greater pressure and gravity load.

3. Good welding effect: seamless steel pipe is generally forged directly with its raw materials, its defect rate is low, easier to weld, easy to polish and clean after welding, so it is not easy to leak and leak when in use.

4. Smooth surface: seamless steel pipe surface smooth, no burrs, with good internal surface roughness, to ensure the flow of fluid in the pipeline and transmission efficiency.
