Quick Detail

Description:

Manufacturing process: The longitudinal I/L or U shape fins are welded onto the core plain tubes by resistance welding or welding with filler matal (Spot welded).

? 1. U bends tubes with longitudinal fins and fintube coils are avaiable for requesting.

? 2. Longitudinal fins types: one-piece shape, standard U bent shape, cut & twist, perforated type etc…

? 3. The fin channels are welded to the tubes in opposite pairs. Fin height, number of fins and fin thickness can be specified.

? 4. Fins can be applied to either OD tube or NB pipe.

Applications:

The longitudinal finned tubes are wildely used in following fields.

1.??? Chemical- ,petrochemical-,oil-, and power indudtry

2.??? Heat exchanges

3.??? Fired heaters

4.??? Gas coolers and heaters

5.??? Tank heaters.

Specifications:

Competitive Advantage:

1.??? Longer working life than others ordinary welding helical fin tubes.

2.??? Much safer and energy
