Finned-tube coils are found in many heat exchange processes that exchange gas to liquid. Finned-tube coils have two important parts that convey heat transfer. The first is the coil tubes, which also are called the "primary surface." The second is the finned outside surface, which also is known as the "secondary surface". The fins on a coil accomplish two major functions. First, they straighten the air out as it comes in contact with the entering-air side of the tube coil surf

The tubes we manufacture and deliver for heat exchange and other cooling application systems are noted for their quality and low lifecycle costs for the following reasons: We control every step in the tube production process, ensuring the best quality in our product. We have well equipped testing labs, and for the control of the production procedures on different material, that result in a product that offers high corrosion resistance. High surface smoothness and close dimens

Seamless steel pipe manufacturing process starts with a solid, round steel billet. This billet is then heated to great temperatures, pulled over a form until it takes the shape of a hollow tube. As other steel manufacturers will tell you, there are great advantages to making a pipe this way. Increased Pressure Rating The best advantage of seamless steel pipes is their increased ability to withstand pressure. The weakest point in a welded steel pipe is the welded seams. But be

To provide the same amount of heat transfer as a straight tube heat exchanger for smaller spaces, engineers replace the straight inner pipe with a helical tube coil. This allows for more heat transfer in a smaller length shell, but increases the pressure drop across the heat exchanger. Helical coil heat exchangers have a more complex flow patterns due to the geometrical configuration of helical coils, which also imparts centrifugal force on the inner coil flow while increasin

Heat exchangers are tools that facilitate the exchange of heat between two fluids that are at different temperatures while keeping them from interfering with one another. Heat transfer in a heat exchangers usually involves convection in each fluid and conduction through the wall separating the two liquids. The rate of heat transfer between the two liquids at a location in a heat exchanger depends on the magnitude of the temperature difference at that location, which varies al

Stainless steel is a cheap and benificial material to use for pipes or tube coils. One reason stainless steel provides a better heat exchange is the fact that many types of stainless steel are resistant to corrosion and oxidation. Stainless steel maintains this resistance in virtually all cooling waters and many chemical environments. Stainless steel has the ability to be fabricated for customized production. The ability to be welded and formed, gives stainless steel yet anot

Less corrosion: Stainless steel is a very anti-corrosive material. The metal will retain its rust-free appearance for years, even when water constantly flows inside the tubing. The metal is unlikely to leach into the water. Contamination rate for stainless steel is nearly nonexistent. Aesthetics: Stainless steel pipes are attractive, the sleek and modern look make this material appealing. It is possible to leave stainless steel pipes exposed inside a building and have that ad

The ferritic structure of grade UNS S44660 stainless steel provides a high strength/low work hardening material with good ductility. Ferritic properties allow high stress limits with good fabrication characteristics, because nickel addition to the ferritic steel it holds a lower ductile-to-brittle transition temperature. Similar ferritic steel without nickel additions do not compete with this grade. Significantly higher elastic modulus allows the use of a lighter wall with le

Copper is a great conductor of heat. This means that if you heat one end of copper, the other end will reach the same temperature quickly. Most metals are good conductors of heat; however, apart from silver, copper is one the best. It is used in many heating applications because it doesn't corrode and has to reach high temperatures to melt. Apart from copper, the only other material that has similar resistance to corrosion is stainless steel. However, its thermal conductivity
