Internal Rib Condenser Seamless DIN1629 Low Carbon Steel Tube
CuNi70/30 , CuNi90/10 , 26FPI With Internal Rib Condenser Low Fin Tubes
Introduction:
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. All integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications. The acceptance certification include WOLVERINE / HPT / GEWA-K & GEWA-KS
Delivery:
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. 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:
