ASTM B111 UNS C70600 O61 Copper Nickel Alloy Low Fin Tube For Heat Exchangers

ASTM B111 UNS C70600 O61 Copper Nickel Alloy Low Fin Tube For Heat Exchangers

ASTM B111 UNS C70600(Cu-Ni 90/10) O61 is a specification for copper nickel alloy low fin tubes. These tubes are commonly used in heat exchangers and other industrial applications where corrosion resistance and thermal conductivity are important. Copper nickel alloy tubes are known for their excellent resistance to corrosion in seawater and other harsh environments. They also have good thermal conductivity, making them suitable for use in heat transfer applications. The low fin design of these tubes increases the surface area available for heat transfer, improving overall efficiency. This makes them a popular choice for use in condensers, evaporators, and other heat exchangers where maximizing heat transfer is important. ASTM B111 UNS C70600 O61 copper nickel alloy low fin tubes are a reliable and durable option for demanding industrial applications where corrosion resistance and thermal conductivity are key considerations. Our major material grades include UNS C70600 / C71500 / C12200 / C12100 / C68700 / C44300 etc.

Quick Detail:

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:

• 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.
