1. Material Composition & Key Properties

1.1 Chemical Composition (per ASTM/ASME Standards)

1.2 Mechanical & Thermal Properties

2. Seamless vs. Welded 316Ti Stainless Steel Pipes

3. Specifications & Standards

3.1 Common Dimensions

• Outer Diameter (OD): 6 mm – 2,000 mm (varies by seamless/welded).
• Wall Thickness (Schedule): SCH 5S, SCH 10S, SCH 20S, SCH 40S, SCH 80S, SCH 160, XS (Extra Strong), XXS (Double Extra Strong).
• Length:
  • Seamless: 3 m – 12 m (fixed lengths) or custom cut-to-length.
  • Welded: Up to 18 m (continuous lengths) or custom lengths.

4. Applications

4.1 Chemical & Petrochemical Industry

• Piping for transporting acidic/basic chemicals (e.g., sulfuric acid, nitric acid).
• Reactor tubes, heat exchanger tubes, and distillation columns (resistant to high temps and chemical attack).

4.2 Oil & Gas Industry

• Seamless pipes for offshore platforms (resistant to seawater corrosion) and onshore high-pressure gas pipelines.

4.3 Power Generation

• Boiler tubes and steam pipes in thermal power plants (withstands continuous exposure to 600–800°C).

4.4 Food & Pharmaceutical Industry

• Welded pipes for hygienic processing lines (e.g., dairy, beverage, pharmaceutical manufacturing) – polished surfaces prevent bacterial growth.

4.5 Water Treatment & Desalination

• Pipes for reverse osmosis (RO) systems and seawater desalination plants (resists pitting from saltwater).

4.6 Architectural & Construction

• Welded pipes for decorative structures (e.g., handrails, facades) and HVAC systems (corrosion-resistant in urban environments).

5. Other 316Ti Stainless Steel Products

• 316Ti Stainless Steel Tubes: Smaller-diameter (≤ 15 mm OD) than pipes; used in instrumentation, medical devices, and heat exchangers (per ASTM A213).
• 316Ti Plates & Sheets: Thick plates (6 mm – 200 mm) for pressure vessels, tank bottoms, and structural components; thin sheets (0.3 mm – 6 mm) for cladding or decorative panels (per ASTM A240).
• 316Ti Bars & Rods: Solid round/square bars (6 mm – 300 mm diameter) for machining parts (e.g., valves, fasteners, shafts) (per ASTM A479).
• 316Ti Fittings: Elbows, tees, reducers, flanges, and couplings – matched to 316Ti pipes for leak-free piping systems (per ASTM A403).
• 316Ti Forgings: Custom-machined forgings (e.g., valve bodies, pump casings) for high-stress, high-temperature applications (per ASTM A182).

6. Key Advantages Over Other Stainless Steels

• Superior Corrosion Resistance vs. 316/316L: Titanium stabilizes 316Ti, eliminating intergranular corrosion after welding – a critical flaw in 316/316L when exposed to high temps.
• Higher Heat Resistance vs. 304/304L: Withstands 800°C continuous service (vs. 650°C for 304), making it ideal for power and petrochemical applications.
• Better Strength vs. 316L: Higher carbon content (≤ 0.08% vs. ≤ 0.03% for 316L) gives 316Ti greater tensile strength, suitable for high-pressure systems.
