ASTM A213 TP316L Stainless Steel Seamless Tube

Material Composition

Key Properties

• Corrosion Resistance: Excellent resistance to acids, chlorides, and saline environments. Ideal for chemical processing, marine, and pharmaceutical applications.
• High-Temperature Performance: Retains strength and oxidation resistance up to ~870°C (intermittent) and ~815°C (continuous).
• Mechanical Properties: Tensile Strength: ≥485 MPa, Yield Strength: ≥170 MPa, Elongation: ≥40%
• Seamless Construction: No welded seams ensure uniformity, higher pressure tolerance, and reliability in critical applications.

Here’s the table summarizing A213 TP316L Stainless Steel Seamless Tube applications and advantages:

1. Power Generation

• Boiler Tubes & Superheaters: Withstand high-pressure steam (up to 815°C continuous) in coal-fired, nuclear, or combined-cycle power plants. Resist oxidation and scaling in aggressive flue gas environments.
• Heat Exchangers/Condensers: Transfer heat efficiently in cooling systems while resisting chloride-induced pitting (common in coastal or brackish water).

2. Oil & Gas (Onshore/Offshore)

• Downhole Tubing: Used in sour gas wells (H₂S/CO₂ environments) due to resistance to sulfide stress cracking.
• Process Piping: Transport corrosive hydrocarbons, acids, or seawater in refineries and offshore platforms. Mo content (2–3%) prevents pitting in chloride-rich offshore conditions.

3. Chemical & Petrochemical Processing

• Reactor Coils & Transfer Lines: Handle aggressive acids (e.g., sulfuric, acetic) and caustic solutions at elevated temperatures.
• Catalytic Cracker Units: Resist carburization and thermal cycling in high-temperature hydrocarbon processing.

4. Pharmaceuticals & Biotechnology

• Sanitary Process Systems: Smooth, crevice-free seamless interior meets FDA/3-A hygiene standards for sterile fluid transfer. Resists CIP (clean-in-place) chemicals and biofouling.
• Autoclaves & Fermenters: Withstand steam sterilization (high heat/pressure) without corrosion.

5. Food & Beverage

• Brewery & Dairy Equipment: Used in pasteurizers, heat exchangers, and CIP systems due to non-reactive surface and ease of cleaning.
• Saltwater Processing: Ideal for desalination plants (resists saltwater corrosion).

6. Marine & Coastal Environments

• Shipbuilding: Seawater cooling systems, ballast piping, and exhaust scrubbers (resists saltwater pitting).
• Desalination Plants: High-pressure RO (reverse osmosis) tubes for brine handling.

7. High-Temperature Furnaces

• Radiant Tubes & Heat Treatment Equipment:
• Operate in carburizing or oxidizing atmospheres up to 870°C (intermittent).
