Copper Finned Tube For Heat Exchanger

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of copper finned tube for heat exchanger in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount copper finned tube for heat exchanger for sale here from our factory. Customized orders are welcome.

 

When your shell and tube heat exchanger needs higher heat transfer density, a copper finned tube is the most efficient solution. By adding fins to the outside surface, you can achieve 2 to 10 times the heat transfer area compared to a bare tube, using the same shell diameter.

 

We manufacture copper finned tube for heat exchanger applications including heat exchanger hvac units, heat exchanger air coolers, heat exchanger condenser systems, and shell tube evaporator assemblies. Our finned tubes are produced as integral low fin tubes, high fin tubes, and extruded fin tubes depending on your duty requirements.

 

Available in ASTM B111, ASME SB111, EN 12451, and JIS H3300 copper alloys including C12200, C70600, and C71500. Each copper finned tube comes with full mill test certificates and 100% eddy current testing of the base tube before finning.

All three types are available in C12200 for clean water and refrigerant service, and C70600 or C71500 for seawater or corrosive shell-side fluids.

Submit Your Custom Requirements

The base tube material for your copper finned tube for heat exchanger must resist corrosion on both the tube side and shell side. We offer the same ASTM B111 alloys used for bare tubes, with additional formability requirements for fin rolling.

Alloy	Common Name	Best Application	Corrosion Resistance	Fin Rollability
ASTM B111 C12200	Phosphorus Deoxidized Copper	heat exchanger hvac, refrigerant, clean water	Good for clean water and air	Excellent (most ductile)
ASTM B111 C70600	Copper Nickel 90/10	Marine heat exchanger condenser, shell tube evaporator with seawater shell side	Excellent for seawater	Good
ASTM B111 C71500	Copper Nickel 70/30	Severe corrosion service, sour gas, high-temperature seawater	Maximum for copper alloys	Fair (requires specialized equipment)
ASTM B111 C44300	Admiralty Brass	Brackish water, moderate dissolved solids	Good for brackish water	Fair
ASTM B111 C68700	Aluminum Brass	High-velocity seawater (above 1.5 m/s)	Good for erosion resistance	Fair

Alloy selection for a copper finned tube for heat exchanger also affects copper heat exchanger tube corrosion resistance. Contact our engineering team for a recommendation based on your shell-side and tube-side fluids.

What is a copper finned tube for heat exchanger?

A copper finned tube for heat exchanger is a tube with extended surface area (fins) on the outside diameter. The fins increase heat transfer between the tube wall and the shell-side fluid, especially when that fluid is a gas or air with low heat transfer coefficient.

 

How does a finned tube compare to a bare tube?

When comparing copper heat exchanger tube vs stainless steel or bare tube, the finned version provides 2 to 10 times the surface area per linear meter. For heat exchanger hvac and heat exchanger air duties, this means a much smaller shell and tube heat exchanger.

 

Where can I buy copper finned tubes for heat exchanger condenser units?

We are a direct copper heat exchanger tube factory serving copper heat exchanger tube USA, Europe, Germany, UAE, Saudi Arabia, and India. We ship finned tubes as straight lengths or pre-assembled into u tube bundle heat exchanger configurations.

 

What is the copper finned tube price compared to bare tube?

Copper finned tube price is higher per meter than bare tube because of the additional rolling or extrusion process. However, the cost per unit of heat transfer is usually lower because fewer finned tubes are required. For a copper heat exchanger tube cost per meter comparison, send us your bare tube and finned tube specifications.

 

Can I get a quote for copper finned tube for a shell tube evaporator?

Yes. Send us your tube sheet layout, bundle diameter, shell side fluid, and duty requirement. We will provide a firm get a quote for copper heat exchanger tube response within 24 hours including fin type, alloy, and pricing.

 

What standards do your finned tubes meet?

Our finned tubes start with ASTM B111 or ASME SB111 base tubes. The finning process follows industry standards including EN 12451 and JIS H3300. We provide ASTM B111 pdf and ASME SB111 pdf upon request.

 

How to weld or attach copper finned tubes to a tube sheet?

How to weld copper heat exchanger tube with fins is not recommended near the finned section. For heat exchanger tube expansion or tube rolling, only the bare ends of the tube (typically 50mm to 100mm) should be inserted into the tube sheet. We supply finned tubes with bare ends specifically for this purpose.

 

What is the difference between integral fins and extruded fins?

Integral fins are rolled from the base tube wall – no separate material added. Extruded fins are formed from a copper sleeve over the base tube. For copper finned tube for heat exchanger in clean service, integral fins are preferred because there is no bond line to fail.
