low Finned tube

Metallic integral helical low finned tube, Fin pitch 19FPI/26FPI/28FPI/30FPI/36FPI/43FPI

FOREWORDS

The heat exchange is a very important factor in the process of treatment of hydrocarbons; it allows obtaining the operating conditions in the various stages of treatment of gas, so as to obtain an optimal production yield.

Description: 
Manufacturing process: The fins are rolled out of outer wall of the plain tubes by a pass roller. Tubes and fins are in same piece tube. We call it “N” fin type.
 
Delivery of Low Fin Tubes
We can provide the integral low fin tubes with un-finned section gaps( 5mm Min.) in the middle of core tube, or bent with designed Bend Radius.
 
Quality Test:
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications.

 Acceptance ceritia: 
 WOLVERINE  /  HPT  / GEWA-K & GEWA-KS 
 
Delivery condition:
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish.
The desiccants are put into the each package for continental transportation.
 
 
Applications: 
​The Integral Low Finned Tubes find the preference in the following industrial sectors:

1. Heating systems
2. Ventilation systems
3. Refrigeration and climate control systems
4. Mechanical engineering
5. Automotive manufacturing
6. Chemicals and pertrochemical and power plant technology
