ASTM A312 TP316L welded longitudinal finned tubes with stainless steel fins are designed for high-temperature and corrosive service applications. These tubes feature seamless, straight-seam welded construction with automatic welding process and no filler metal addition.
All pipes are heat-treated at 1900°F [1040°C] and are free of scale and contaminating exogenous iron particles. Surface finishing options include pickling, blasting, or bright annealing with optional passivating treatment.
Each tube undergoes rigorous testing including: Transverse/Longitudinal Tension Test, Flattening Test, Grain Size Analysis, Flaring Test, Flange Test, Hardness Test, and Hydrostatic/Nondestructive Electric Test.
| Grade | C | Mn | P | S | Si | Cr | Ni | Mo |
|---|---|---|---|---|---|---|---|---|
| TP316L S31603 | 0.035 | 2.00 | 0.045 | 0.030 | 1.00 | 16.0-18.0 | 10.0-14.0 | 2.00-3.00 |
For small diameter or thin wall tubes (less than 0.500 in. [12.7 mm] in outside diameter and less than 0.049 in. [1.20 mm] in wall thickness), a carbon maximum of 0.040% is required.
| Grade | Tensile Strength (min) | Yield Strength (0.2% Offset, min) | Elongation (min) |
|---|---|---|---|
| TP316L | 70ksi (485 MPa) | 25ksi (170 MPa) | 35% |
Longitudinal finned tubes are produced by resistance welding fins along the tube's length. The fins form a U-shaped channel where each leg creates a fin. Available in various materials including carbon/alloy steel, stainless steel (TP304, TP316L, TP321), and copper alloys (CuNi 70/30, CuNi 90/10).
Ideal for power stations and high-temperature equipment in oil industry applications including:
