ASTM A269 TP317L Bright Annealed Tube supplier
Whether you are dealing with acidic flue gases, paper mill liquors, or pharmaceutical processing, our TP317L stainless steel tubes provide the superior durability your project demands. We specialize in supplying ASTM A269 TP317L cold rolled bright annealed (BA) stainless steel tubes, specifically engineered for industries with high risks of pitting and crevice corrosion.
GNEE provides ASTM A269 TP317L instrumentation tubing that meets global standards and specific customer requirements, making us a trusted partner for your most demanding projects. Standard tubes often fail prematurely in high-chloride or acidic media. Our TP317L seamless tubes feature an enhanced Molybdenum content (3.0% to 4.0%), offering significantly higher resistance to localized corrosion-making them the ideal choice for chemical plants, marine equipment, and flue gas treatment systems.
Our A269 TP317L bright annealed tubes are manufactured using advanced cold rolling and Bright Annealing (BA) technology. Processed in a hydrogen-protected atmosphere to eliminate the need for pickling, these tubes achieve an ultra-smooth internal surface with a roughness of Ra ≤ 0.4μm. This ensures maximum flow efficiency and solves the "clogging and cleaning" challenges common in high-purity systems. To meet your exact specifications, we offer customized lengths and high-precision tolerances of up to ±0.05mm, ensuring a perfect fit for every application.

Pharmaceutical & Biotech: Used in process piping and equipment requiring high cleanliness, hygiene, and corrosion resistance.
Chemical & Petrochemical Processing: Ideal for transporting corrosive fluids, acids, and high-temperature service due to superior molybdenum content.
Food & Beverage Industry: Suitable for sanitary, high-purity transfer lines.
Instrumentation & Control Systems: Used in precision instruments requiring high corrosion resistance.
GNEE offers TP317L cold-rolled, bright-annealed instrument tubing conforming to ASTM A269. All tubing is precision cold-rolled and bright-annealed to a surface roughness of Ra ≤ 0.2μm. Outside diameter tolerances are ±0.05mm, and wall thickness tolerances are ±0.03mm.
We offer comprehensive quality assurance, including a factory test certificate with complete chemical and mechanical property data, a third-party inspection report, and surface quality verification to meet the stringent requirements of instrumentation and analytical equipment applications.
inspection
Non-destructive testing (NDT): 100% eddy current testing or hydrostatic testing to ensure the pipe wall is free of any microscopic cracks or leaks.
Chemical analysis: Using particle spectroscopy (PMI) to verify that the molybdenum (Mo) content is within the range of 3.0%-4.0%.
Mechanical testing: Including tensile strength, yield strength, elongation, and flaring and flattening tests.
ASTM A269 TP317L seamless stainless steel Tube Factory
Annual Capacity: Our professional stainless steel instrument tubing production capacity exceeds 5,000 tons annually.
Advanced Equipment: We possess multiple multi-roll precision cold rolling mills and a 60-meter-long continuous hydrogen-protected bright annealing furnace, ensuring the straightness and surface consistency of our tubing.
Stock Program: We maintain ample stock of TP317L raw materials and semi-finished billets for commonly used sizes such as 1/4", 3/8", and 1/2", shortening lead time to 7-15 days.
high quality packaging
Individual Protection: Each tube is individually wrapped in a PE plastic bag or protective sleeve to prevent metal-to-metal friction.
End Protection: Both ends are equipped with high-strength plastic caps to prevent dust, moisture, and impurities from entering the tube.
Outer Packaging: Packed in export-grade fumigated wooden crates or steel frame structures. The wooden crates are lined with waterproof fabric and secured with reinforcing straps to ensure safe ocean shipping.
Marking: The tube body is clearly printed with: standard, material, specifications, heat number, and batch number, ensuring 100% traceability.
