General Low Fin Tubes Production Capacity | Specifications of Low Fin Tubes('N' Fins) |
Finning Facility: 10 finning machines; Daily capacity up to 3000 meters; | Tube OD: 12.7 mm~25.4mm Tube Length: 18 meters max. Fin Height: 1.2 mm ~2.77mm Fin Thickness: appr. 0.3mm Fin Pitch: 30 FPI /28 FPI/ 26 FPI/ 36 FPI /43 FPI |
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 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.
