Delivery Range 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.
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications.
WOLVERINE / HPT / GEWA-K & GEWA-KS
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.
The Integral Low Finned Tubes find the preference in the following industrial sectors:
Tube and fins consist of same tube and materials as carbon steel , low-alloy steels , stainless steel , brass , copper , cooper-nickel alloys , aluminum bronze , nickel alloys , titanium etc...
