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:
It is used for boiler and boiler flue tubes. Including safe end, vault and supporting tube and super heater min wall thickness seamless medium--carbon steel tube
