A179 seamless carbon steel corrugated slot heat exchangers tube
The fins are rolled out of outer wall of the plain tubes by a pass
roller. Tubes and fins are in same piece tube.
Popular Tube Materials:
ASTM A106 / 106M : Seamless Carbon Steel Pipe for High-Temperature Service
ASTM A179 / A179M : Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser
ASTM A192 / A192M : Seamless Carbon Steel Boiler Tubes for
ASTM A210 / A210M : Seamless Medium-Carbon Steel Boiler and Superheater Tubes
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.

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
The Integral Low Finned Tubes find the preference in the following
- Heating systems
- Ventilation systems
- Refrigeration and climate control systems

- We have more than 10,000 square meters workshop, including 10
finning machines, daily extrusion capacity up to 3,000 meters.
- The finning machines of Integral Low Fin Tubes are designed and
assembled by ourselves and we can offer you finning machines and
all accessories etc...
- The Integral Low Fins are rolled out of the tube surface to
increase the tubes external surface area, without affecting any
- Low Fins are very useful for tight condensers and exhibits high
efficiency of heat transfer.
- Economical solutions of heat exchange problems of media with
different heat conduction abilities or different current
- High chemical-, thermal- and mechanical resistance, suitable for
rough operation conditions.
