Description
Application:
- Oil and gas refineries
- Petroleum, chemical and petrochemical industries
- Natural gas treatment
- Steel making industry
- Power plants
- Air conditioning
- Compressor coolers
Advantages:
- High fin stability, excellent heat transfer, high operating temperature.
- The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.
- The fin is set throughout its length and consequently does not unwind even when partially uprooted.
- This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.
Weakness:
- The fin is not so strong to resist mechanical damage when external forces applied on fin area
- Handling shall be done with care to avoid any damage.
- Finned tubes may be damaged while using either steam or high-pressure water for cleaning
- As the fins are helically wrapped in grouves, un-finned area is not covered which can be exposed to corrosive media and galvanic corrosion at the base of the fins can be accrued
- Tube shall be straight with smooth out side area to make a good finned tube
- It is hard to use core tube again when finning is failed.
- Fins should be fixed at both ends avoiding un-wrapping
