What is the difference between TP317 and TP317L in coiled tubing applications?
- Carbon Content: TP317L has a lower carbon content (≤0.03%) compared to TP317, which minimizes the risk of carbide precipitation during welding.
- Corrosion Resistance: The reduced carbon in TP317L enhances resistance to intergranular corrosion, making it ideal for high-chloride and welded applications.
- Mechanical Strength: TP317 provides slightly higher tensile and yield strength than TP317L, making it suitable for applications where higher mechanical properties are required.
- Applications: TP317L is commonly used in heat exchangers, condensers, and chemical process piping where welding is frequent, whereas TP317 may be chosen for general corrosion-resistant tubing with moderate mechanical requirements.
What testing is performed on ASTM A269 TP317/317L coiled tubes?
- Eddy Current Testing: Ensures the tube surface is free from cracks, laps, or internal defects.
- Hydrostatic Testing: Confirms the tube can withstand internal pressure without deformation or leakage.
- Intergranular Corrosion Testing: Verifies the material’s resistance to sensitization and corrosion along grain boundaries.
- Flattening Test: Checks the tube’s ductility and confirms it can withstand bending or shaping without cracking.
- Dimensional Inspection: Validates precise outside diameter, wall thickness, coil length, and uniformity to meet ASTM A269 specifications.
Are custom coil sizes available for TP317/317L stainless steel tubing?
- Diameter & Wall Thickness: Coils can be manufactured in a wide range of diameters and wall thicknesses to match process requirements.
- Coil Lengths: Custom lengths can be provided for specific equipment layouts or project specifications.
- Surface Finishes: Available in bright annealed, pickled & passivated, or other finishes for corrosion protection and improved surface quality.
- Application Specifics: Tailored for heat exchangers, condensers, instrumentation lines, and other industrial applications where precision tubing is required.
