Product Description

Longitudinal Finned Tubes ASTM A312 TP316L Welded Tubes With Stainless Steel Fins

Details of ASTM A312 Base Tubes

ASTM A312 This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.

Manufacture: Welded (WLD) pipe shall be made using an automatic welding process with no addition of filler metal during the welding process.

Heat treatment: All pipe shall be furnished in the heat-treated condition in accordance with the requirements 1900°F [1040°C].

Surface Condition: The pipe shall be free of scale and contaminating exogenous iron particles. Pickling, blasting, or surface finishing is not mandatory when pipe is bright annealed. The purchaser is permitted to require that a passivating treatment be applied to the finished pipe.

Tests: Transverse or Longitudinal Tension Test, Flattening Test, Grain Size, Flaring Test, Flange Test, Hardness Test, Hydrostatic Test or Nondestructive Electric Test

Chemical Composition (%)

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 walls or both, where many drawing passes are required, a carbon maximum of 0.040% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500 in. [12.7 mm] in outside diameter and light wall tubes as those less than 0.049 in. [1.20 mm] in average wall thickness (0.044 in. [1.10 mm] in minimum wall thickness).

TP316L	70ksi (485 MPa)	25ksi (170 MPa)	35%

Definition

Longitudinal finned tubes are produced by resistance welding fins along the long direction of the tube. The fins first form a U-shaped channel so that each leg of the U-shape forms a fin.

Regular base pipe/tube material: carbon / alloy steel (A106, A333, A179, A335 P5, P22, P9, etc.), stainless steel TP304, TP316L,TP321, etc., copper alloy CuNi 70/30, CuNi 90/10, etc and other material.

Advantages

Reduce the installation space of the required heat transfer surface and at the same time, it has high reliability
Improve the heat transfer efficiency in the effective space
Heat transfer is strengthened to reduce flow resistance and metal consumption, etc.

Application

Generally applicable to power stations or large high-temperature old equipment in the oil industry:

Industrial Furnace
Distillation Tower System
Air Cooled Heat Exchanger
Refining Unit
Petrochemical Separation Equipment
Evaporative Condenser
Closed Circuit Cooling Tower
Waste Heat Boiler
High Temperature Furnace Cooling System
Nuclear Power Plant Heat Exchange System, etc.
