Coiled Copper Fin Tube

Copper fin coils are also special coils that Grand provide. These coils don’t have a bi-metallic bond usually found on standard coils and have a copper wavy fin pattern bonded to the copper tubes.

These coils are very reliable heat exchangers as they are required and can operate for air conditioners in harsh coastal areas and other highly corrosive surroundings because the coils have higher coastal corrosion durability. The coils match this type of environment because the bi-metallic construction is not present, and copper has a natural protective film and a mono-metal bond attaching the tube and fin. They have superb thermal conductivity, resistance and strength compared to aluminium.

What’s good about using copper for these special coils is that it can reduce energy consumption due to its biofouling resistance, rintangan kakisan, antimicrobial properties, ease of fabricating and joining, and less need for maintenance for cleaning coils.

If the copper fins are uncoated, they are no longer suitable for industrial applications. It is because copper can be very vulnerable to contaminants and will not have a long coil life.

Tembaga adalah unsur logam, dan tembaga tulen adalah logam lembut. Permukaannya berwarna oren kemerahan dengan kilauan logam apabila ia hanya dipotong terbuka, dan bahan mudahnya adalah ungu-merah. Kemuluran yang baik, Kekonduksian terma yang tinggi dan kekonduksian elektrik, jadi ia adalah bahan yang paling biasa digunakan dalam kabel dan komponen elektrik dan elektronik.

Ia juga boleh digunakan sebagai bahan binaan dan boleh terdiri daripada banyak aloi. Aloi tembaga mempunyai sifat mekanikal yang sangat baik dan rintangan elektrik yang rendah. Yang paling penting ialah gangsa dan tembaga. Selain itu, Tembaga juga merupakan logam tahan lama yang boleh dikitar semula beberapa kali tanpa menjejaskan sifat mekanikalnya.

Copper pipes (also known as red copper pipes) are commonly used in tap water pipes, heating and cooling pipes, and can be used in different environments. Copper pipes combine the advantages of metal and non-metal pipes in cold and hot water systems. Copper pipes are resistant to high temperatures and can be used in a variety of environments. Compared with this, the shortcomings of many other pipe materials are obvious.

Sebagai contoh, the galvanized steel pipes used in residential buildings in the past are very easy to rust. If they are not used for a long time, the tap water will turn yellow and the water flow will become small. Selain itu, the strength of some materials will decrease rapidly at high temperatures, which may cause unsafe risks when used in hot water pipes. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is negligible for copper pipes.

China Copper Pipe is the best one and is the best connecting pipe. The copper pipe is fire-resistant and heat-resistant, and can maintain its shape and strength under high temperature without aging.

The pressure resistance of copper pipes is several times or even dozens of times that of plastic pipes and aluminum-plastic pipes. It can withstand the highest water pressure in today’s buildings. In the hot water environment, with the extension of service life, the pressure capacity of plastic pipes significantly decreases, and the mechanical properties of copper pipes remain unchanged in all thermal temperature ranges, so their pressure resistance will not decrease, nor there will be aging.

Copper finned tubes manufacturing process

Pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging. The cold machining process of fins provides excellent mechanical resistance , fins are strong and have strong resistance to atmospheric corrosion, Dll. The pressure required to extrude the fin from the aluminum sleeve creates an excellent “pressure bond” between the two materials. Selain itu, the aluminum finned material completely surrounds the metal of the tube, so there is no risk of electrical corrosion at the fin root (between the tube and the fin). All of these advantages ensure the most stable performance over time of all other fin types.

Copper finned tube applications

Copper finned tubes products are widely used in petrochemical, power plant and power plant renovation, air conditioning and refrigeration, boilers, finned tube economizers and air preheaters.
