Quick Detail:

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.

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

Specifications:
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...

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.
