Key Features & Advantages:
- Enhanced Corrosion Resistance: The 316L grade contains molybdenum, providing superior resistance to chlorides, acids, and pitting compared to standard 304 stainless steel.
- 2B Surface Finish: A bright, smooth finish that reduces friction, improves cleanability, and is ideal for sanitary and food-grade applications.
- Precise Dimensional Tolerance: Our pipes are manufactured with tight tolerances to ensure seamless integration with fittings and flanges, reducing installation time and costs.
- Standard Compliance: Each pipe undergoes rigorous testing (hydrostatic, eddy current, or ultrasonic) to meet ASTM and other international standards, ensuring reliability and safety.
- Customizable Options: Wall thickness, length, and end finishing (plain, beveled) can be tailored to your specific project requirements.
- Long Service Life: The low carbon content (0.03% max) minimizes carbide precipitation during welding, extending the lifespan in high-temperature environments.
Our 316L welded tubes are widely used in:
- Chemical and petrochemical piping systems
- Oil and gas gathering lines
- Food and beverage processing equipment
- Pharmaceutical and biotech facilities
- Water treatment and desalination plants

Frequently Asked Questions
-
Q: What is the difference between 316L and 316 stainless steel?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%), which reduces the risk of carbide precipitation during welding, making 316L more suitable for welded applications where corrosion resistance is critical. -
Q: Can this pipe be used for high-pressure applications?
A: Yes, depending on the wall thickness. Our pipes are available in various schedules (SCH10, SCH40, etc.) and are tested to withstand specified pressure ratings. Please consult our technical team for specific pressure requirements. -
Q: Is the 2B surface finish suitable for food contact?
A: Yes, the 2B finish is smooth and non-porous, making it easy to clean and ideal for food processing and pharmaceutical applications where hygiene is paramount. -
Q: Do you offer custom lengths or cut-to-size services?
A: Absolutely. We can provide pipes in custom lengths according to your drawings or specifications. Minimum order quantities may apply for non-standard lengths. -
Q: What quality certifications do you hold?
A: Our company is ISO9001 certified, ensuring a comprehensive quality management system. We also perform third-party inspections upon request. -
Q: What is the typical lead time for an order?
A: Lead time depends on quantity and specifications. For standard sizes and finishes, it is usually 15–25 working days. Custom orders may require additional time. -
Q: Can you provide a mill test certificate (MTC) with each shipment?
A: Yes, we provide MTCs traceable to the heat number, including chemical composition and mechanical properties, as per ASTM standards. -
Q: What packaging methods do you use for export?
A: We use seaworthy packing: each pipe is wrapped with plastic, bundled with steel strips, and protected with wooden crates or pallets as needed to prevent damage during transit.
