  Wall hung boilers have become the third largest gas product after gas water heaters and gas stoves, and wall-hung boilers are used most often in household heating. Wall-hung boilers can not only provide users with domestic hot water, but also heat the home. Wall-hung boilers can be divided into single-heating and dual-purpose boilers in terms of function, and they can be divided into instant heating and volumetric heating methods. The instant heating models are divided into casing machines and plate changers. What is the difference between a wall-hung boiler casing machine and a plate changer? How much do you really know? Did you choose the right one? The  heat exchanger  can be described as the core component of the gas wall-hung boiler, which is responsible for heat exchange between the flue gas generated after the combustion of the gas and the water in the system. From the perspective of the heat exchange structure of the heating and hot water functions of the ordina...

What  is fin tube heat exchanger Fin tube heat exchanger   is a kind of heat exchange equipment used in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube. The   fin tube heat exchanger  is one of the earliest and most successful discoveries in the process of improving tube heat transfer. This method is still the most widely used method among all tube heat transfer surface enhancement methods.  It is not only suitable for single-fin tube heat exchangers, which are widely used in power, chemical, petrochemical, air-conditioning engineering and refrigeration engineering. Structure of   fin tube heat exchanger The basic heat transfer element of the  fin tube heat exchanger  is a finned tube, a finned tube mountain base tube and a fin combination. The base tube is usually a round tube, but there are also oval tubes and flat tubes. The surface structure of the fins ...

In the petrochemical industry, the application of Murphy heat exchangers are indispensable. High-efficiency #plateheatexchangers : can better deal with higher pressure and temperature. Specifically, the welded plate heat exchanger has strong convenience, small size, light weight, good heat transfer performance and low price. Therefore, it has been better used in the petroleum production process. The high-efficiency plate heat exchanger can cool mechanical lubricating oil and fresh water, can cool oil field related intermediate products, and can also heat crude oil. #Spiralheatexchanger: This is a modern and efficient heat exchanger equipment, widely used in many countries and the petrochemical industry in the region. Compared with traditional heat exchangers, spiral plate heat exchangers have many advantages, mainly including: high heat transfer coefficient, self-washing and anti-deposition, etc. Spiral baffle heat exchangers have achieved very good application effects in the petrochem...

Copper extruded finned tube has excellent heat conduction characteristics. The fins increase the heat exchange area, improve the heat conduction performance, increase the heat exchange rate, and save energy and material. Murphy copper fin tubes are widely used in various types of heaters, heat exchangers, refrigeration equipment, chemical engineering, power station auxiliary machinery, ship auxiliary machinery cooling machine.

Laser welding finned tube Laser welding spiral finned tube is processed by laser welding machine. Stainless steel laser welded spiral finned tube In traditional spiral finned tubes, high frequency welding, resistance welding and other techniques are used to attach stainless steel fins to the steel tube. Laser welding finned tube, the welding process has its shortcomings that cannot be overcome. The laser welding spiral finned tube has a fully automatic welding process, which saves labor costs; secondly, the laser welding fins are firm and strong, and the high tensile strength test is qualified; laser welding has higher efficiency advantages. Laser welding machine is the most advanced spiral finned tube laser welding equipment.
