Ventilation System Carbon Steel A334 Gr3 Low Fin 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
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 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.
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:
Heating systems
Ventilation systems
Refrigeration and climate control systems
Mechanical engineering
Automotive manufacturing
Chemicals and pertrochemical and power plant technology
