Products Description
Our advantages
1. Corrosion Resistance
Our 316 Welded Stainless Steel Pipe is made of premium 316 stainless steel, with chromium providing excellent corrosion resistance. It has passed salt spray testing and exhibits superior durability in chloride-rich environments, making it suitable for acidic and seawater environments.
2. Surface Quality
Our pipes undergo pickling and polishing, resulting in a smooth surface without weld discoloration. Mirror polishing, brushing, and other surface treatments are available upon request to reduce bacterial growth and corrosion.
3. High Strength and Durability
Our 316 Welded Stainless Steel Pipe possesses excellent mechanical strength and has been mechanically tested to ensure it does not deform under load, vibration, or thermal cycling, making it ideal for industrial, marine, and high-pressure piping systems.
4. Customization Services
We offer flexible customization services to meet your specific project needs. Pipe length, wall thickness, diameter, and tolerances can all be customized. Furthermore, we provide precision cutting, bending, and end-finishing services, enabling easy integration into complex piping systems or assembly components.
5. Quality Assurance
Our raw materials undergo rigorous quality control, including chemical composition testing, mechanical property testing, dimensional inspection, and weld evaluation. Each batch of pipes is traceable, ensuring compliance with international standards such as ASTM, ASME, and ISO 9001.

Steel Grade
- 316: Standard molybdenum-bearing grade, widely used in chemical and marine service
- 316L: Low-carbon version, excellent resistance to intergranular corrosion after welding
- 316H: High-carbon version, improved strength at elevated temperatures
Possible Alternative Grades
- 317L: higher molybdenum content for stronger resistance in aggressive media
- 2205 Duplex Stainless Steel: higher strength and superior resistance to stress corrosion cracking
- 904L: excellent resistance to strong acids and seawater corrosion
- Nickel alloys (Inconel, Hastelloy): for extreme temperature and highly corrosive environments
