TP317L stainless steel seamless pipe is a premium austenitic stainless steel product known for its excellent corrosion resistance, high-temperature performance, and mechanical strength. It is widely used in industries requiring resistance to harsh environments, making it a reliable choice for critical applications.
Key Parameters of 317L Stainless Steel Pipes
- Material Grade: TP317L (low-carbon version of 317, with carbon content ≤0.03%)
- Chemical Composition (typical, %):
- Chromium (Cr): 18.00-20.00
- Nickel (Ni): 11.00-15.00
- Molybdenum (Mo): 3.00-4.00
- Manganese (Mn): ≤2.00
- Silicon (Si): ≤0.75
- Phosphorus (P): ≤0.045
- Sulfur (S): ≤0.030
- Carbon (C): ≤0.03
- Pipe Type: Seamless (no welding seams, ensuring uniform strength)
- Schedule: SCH40S, SCH80S (standard wall thicknesses per ASME B36.19)
- Manufacturing Process: Hot-rolled (enhances mechanical properties and dimensional stability)
- Size Range: Typically available in outer diameters (OD) from 1/8" to 24", with wall thicknesses (WT) corresponding to SCH40S/SCH80S standards.
- Length: Common lengths include 6m, 12m, or customized lengths as per requirements.
- Surface Finish: Annealed and pickled (AP), polished, or as specified.
Standards Compliance of 317L Stainless Steel Pipes
TP317L seamless pipes are primarily manufactured in accordance with ASTM A312, a widely recognized standard for seamless and welded austenitic stainless steel pipes for high-temperature and general corrosion service. Additional standards may include:
- ASME B36.19 (for dimensions and schedules of stainless steel pipes)
- EN 10216-5 (European standard for seamless stainless steel pipes)
Performance Characteristics of 317L Stainless Steel Pipes
- Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and general corrosion, especially in chloride-rich environments (superior to 304/316 due to higher molybdenum content).
- High-Temperature Resistance: Maintains strength and oxidation resistance at elevated temperatures (up to 800°C), suitable for high-heat applications.
- Mechanical Properties (typical, annealed condition):
- Tensile Strength: ≥485 MPa
- Yield Strength: ≥170 MPa
- Elongation: ≥40%
- Formability & Weldability: Good weldability using common methods (TIG, MIG); low carbon content minimizes carbide precipitation during welding, reducing intergranular corrosion risk.
Similar Grades of 317L Stainless Steel
TP317L is part of the austenitic stainless steel family, with (similar grades) including:
- 317L (generic designation, equivalent to TP317L in pipe forms)
- EN 1.4438 (European equivalent)
- JIS SUS317L (Japanese equivalent)
- Note: 317L offers higher molybdenum than 316L, providing better corrosion resistance in aggressive environments.
Packaging of 317L Stainless Steel Pipes
To ensure protection during transportation and storage, TP317L seamless pipes are packaged as follows:
- Bundled with steel straps (for small diameters)
- Wooden crates or pallets (for larger diameters or customized lengths)
- Ends capped with plastic or metal protectors to prevent damage and contamination
- Each bundle/crate is labeled with grade, size, standard, heat number, and manufacturer information.
Applications of 317L Stainless Steel Pipes
Due to its superior properties, TP317L seamless pipes are used in various demanding industries:
- Chemical Processing: For handling acids, alkalis, and corrosive chemicals.
- Oil & Gas: Offshore and onshore pipelines, refineries, and petrochemical plants (resistant to sour gas and saltwater).
- Pharmaceuticals & Food Processing: Sanitary piping systems requiring high purity and corrosion resistance.
- Power Generation: Boiler tubes, heat exchangers, and piping in coal-fired or nuclear power plants.
- Marine Engineering: Saltwater-resistant components in shipbuilding and offshore structures.
