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
