0.3mm A334 Gr6 Threaded 26FPI Carbon Steel Seamless Tube
26FPI / 1024 FPM / 0.976mm , A334 Gr 1 / 3 / 6 Carbon Steel Threaded Fin Tubes
ASTM A334 / A334M: Seamless and Welded Carbon and Alloy-Steel Tubes for Low-Temperature Service
Introduction:
The fin is rolled out from the outer wall of the smooth tube with a pass roller. The tube and fin are in the same tube. We call it the "n" fin. It has many uses such as heating systems, Ventilation systems, Refrigeration and climate control systems, Mechanical engineering, Automotive manufacturing and Chemicals and pertrochemical and power plant technology
All the tubes has assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications. And 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. Besides, the desiccants are put into the each package for continental transportation.
Acceptance Certification:
WOLVERINE / HPT / GEWA-K & GEWA-KS

Data sheet of Low Fin Tubes
Competitive Advantage:
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 others dimension.
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 conditions.
High chemical-, thermal- and mechanical resistance, suitable for rough operation conditions.
