According to customer's requirements.   C.     What is U-Tube heat exchanger? U-shaped tube heat exchanger is a kind of shell and tube heat exchanger, which is composed of tube sheet, shell, tube bundle and other part. Under the same diameter, the heat exchange area of U-tube heat exchanger is the largest. The main structure of the U-tube heat exchanger includes the header, cylinder, head, heat exchange tube, nozzle, baffle, impact plate and draft tube, anti short circuit structure, support and other accessories on the tube and shell side   D.     U-Tube heat exchanger Pros and Cons Pros: The U-tube heat exchanger has only one tubesheet. Both ends of the tube are fixed on the same tubesheet. The tube can expand and contract freely without thermal stress and has good thermal compensation performance; Double tube pass is adopted for the tube pass, with long process, high flow rate, good heat transfer performance and strong pressure bearing capacity. The tube bundle can be extracted from the shell, which is convenient for maintenance and cleaning, simple structure and low cost. Cons: Due to the limitation of the curvature radius of the elbow, the heat exchange tubes with limited tube arranged methods, the innermost tube spacing of the tube bundle is larger, the utilization rate of the tube sheet is lower, and the shell side fluid is easy to form a short circuit, which is adverse to heat transfer. When the tube leaks and is damaged, only the U-shaped tube at the outer of the tube bundle can be easily replaced. If the inner heat exchange tube is damaged, it cannot be replaced. It can only be blocked. Moreover, a damaged U-shaped tube is equivalent to two damaged tubes, with a high scrap rate.   E.      Finned tube coils application and parameter Applications: HVAC / Air Handling Units Heat Pumps  Boiler Economisers Process Drying  Agricultural Drying  Space heating  De-humidification  Process cooling  Heat recovery Air cooling in food manufacture Air heating using steam / thermal oil   Materials: Tubes in copper, steel or stainless steel  Fins in aluminium, copper, steel or stainless steel Frames in galvanised steel, stainless steel, aluzinc or copper Connections in brass, steel or stainless steel We also supply various coatings to protect against corrosive environments   F.         What is Stainless steel coil? Finned tube coils are a type of heat exchanger that is commonly used for transferring heat between two fluids or gases. The coils consist of a series of tubes that are arranged in a circular or rectangular pattern, and these tubes are typically made of copper, aluminum, or stainless steel.   The outer surface of these tubes is coated with thin metal fins that extend outward from the tube surface. These fins increase the surface area of the tube, which in turn increases the efficiency of heat transfer between the fluids or gases flowing through the tubes.   Finned tube coils are used in a wide range of applications, including heating, ventilation, and air conditioning (HVAC) systems, refrigeration systems, and industrial processes that require precise temperature control. They are also used in the production of steam and in power generation applications.   Overall, finned tube coils are a reliable and efficient means of transferring heat between two fluids or gases and are an important component of many industrial and commercial system.   G.     Stainless steel coils Applications: Metals used in chemical industry, machinery, electronics, electric power, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields Stainless steel coil, in English, is generally a coil or mosquito coil with a diameter of 0.5cm to 20mm and a thickness of 0.1cm to 2.0mm; It is widely used in chemical industry, machinery, electronics, power, textile, rubber, food, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields. Stainless steel industrial tubes, ultra long coils, U-tubes, pressure tubes, heat exchange tubes, fluid tubes, spiral coils Product features: high-temperature steam resistance, impact corrosion resistance, ammonia corrosion resistance; It is resistant to scaling, contamination and corrosion; Long service life, reduce maintenance time and save costs; Good pipe installation process, direct pipe replacement, safe and reliable; The pipe wall is uniform, the wall thickness is only 50-70% of that of copper pipe, and the overall thermal conductivity is better than that of copper pipe; It is an ideal heat exchange product for the transformation of old units and the manufacture of new equipment. It can be widely used in petrochemical, electric power, nuclear industry, medicine, food and other industries.
