Finned tube as a heat exchange element exhibits excellent performance indicators

-

Finned tube is a kind of heat exchange element, which is often used in high temperature and flue gas space. In daily life, such as boilers, finned tubes need to be used for heat exchange execution. In such a harsh environment During daily operations, the finned tube itself is required to have corrosion resistance and stability. The finned tube is a typical heat exchange element, in order to improve the heat exchange efficiency, usually by adding fins on the surface of the heat exchange tube to increase the outer surface area of ​​the heat exchange tube, so as to improve the heat exchange For the purpose of efficiency, such a heat exchange tube. Finned tubes work under high-temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in corrosive atmosphere, which requires finned tubes to have high performance indicators. For example, excellent corrosion resistance. Many tim...

  What is G type fin tube Finned tube  is a kind of heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the external surface area (or internal surface area) of the heat exchange tube to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube. The outer surface of the fin tube is covered with small fins. The role of these fins is to act as a transfer process and filter. Heat transfer is usually from the inside to the outside and then in the reverse direction.  G type fin tube, also known as  embedded finned tube , where g means slotted. It is formed by screwing fin strips made of copper or aluminum into machined grooves and backfilling to secure the lock. Fill the base tube material. Compared with other finned tubes,  G type fin tubes are firmer. Therefore, it is widely used in places where high-temperature heat transfer is requir...

Brass tube basic instruction

Brass is an alloy of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. Brass is often used to make valves, water pipes, connecting pipes of air conditioners and radiators. Brass tubes are generally used to make heating coil tubes for condensers and coolers and tubes for general purposes. Brass 68 and 70 for condensers and 62 for general purpose cold drawn tubes from 3 to 100 cm OD. Its length is 1-6 meters. Tubes for condensing cooler and other heat exchange equipment shall be subject to water pressure test with pressure up to 50 kg / cm2, and the test time shall not be less than 10 seconds. Compared with the shell and tube heat exchanger, the brass tube has the following advantages: 1. High heat transfer coefficient, which is due to high velocity, turbulence and complete countercurrent; 1. The weight of equipment required for unit heat transfer is small; 1. The compensation of temperature deformation is good. What are the charact...
