Production Status Of Welded Fin Tube For Boiler
Split bricks have a soft color and are used as decorative materials in villas, buildings, residences and gardens. The split bricks are mainly made of shale, and the surface of the split bricks is not glazed, and then it is fired at a high temperature. It is also easy to fade under long-term ultraviolet radiation, and users who use it can also experience its comfort. Split bricks have moisture absorption and dehumidification functions. The voids inside the bricks can absorb and drain external moisture. During
Classification Of Extruded Fin Tubes
With a trapezoidal fin section, the product quality is good. According to different media and application requirements, the extruded integral finned tube can be divided into: bimetallic finned tube and monometallic finned tube. The bimetallic finned tube is made by composite rolling of two different materials of metal tubes. The base tube types are: copper, copper alloy, stainless steel, carbon steel, etc. The fin material is pure aluminum, which composes two kinds of bimetallic fins. Tube: Copper-aluminum c

The thickest tube we ever finned
High frequency welded spiral finned tubes, 219.1*21.06*10,000, 25*1.3*5.1, TP347H-06Cr13. The thickest tube we ever finned. Bare Tubes are from ZhongXing energy equipment Co., LTD (include: NanTong s
Heat Transfer Effect Of Various Finned Tubes
Finned tubes are divided into integral finned tubes, welded finned tubes, high-frequency welded finned tubes and mechanically connected finned tubes. The whole finned tube is made of casting, machining or rolling, and the fin is integrated with the pipe, such as the economizer of the low pressure boiler is the finned tube which is made by the whole casting. This type of finned tube has no contact thermal resistance, high strength, heat shock and
Application Of Integral Spiral Finned Tube In Boiler Economizer
As early as the middle of the 60, the Soviet Union had studied the KO of the fin, and the economizer of several furnaces had been reformed, and because of the structural characteristics of the fin economizer, not only had the total song M of the coal saving been reduced by 3%, but also the raw materials had been saved, and the wear problem of the economizer had been solved. In Japan, there are also a group of 300-700MW units of the boiler using spiral fin tube economizer. The purpose of using finned tube Economizer in Japa
How To Determine The Heat Dissipation Of Finned Tube
Finned tube heat dissipation of how much is a virtual amount, is not visible to touch, if not measured, calculated or installed improper location, it is easy to affect the heating. So we can take some measures, such as increasing the number of fin tubes of the radiator, because the water flow flowing through the radiator unit time is constant, then in the outer wall of the radiator with finned tube auxiliary, you ca
The More Fins In The Finned Tube, The Better?
Many people have the idea that the more fins the finned tube, the better, but is it really like this? Professionals answer of course not, not that the more fins of the finned tube the better, or that the higher the fins of the fin tube, the better, then, why? Here's the professionals to share with you. First of all, the professionals here introduced, in life, if you can greatly increase the height of the fins of the finned tube, then, then, you can significantly reduce the efficiency of the fin tube, this is
H-finned tube, also known as H-fin tube, H-type rib tube, also known as butterfly tube, it is the two in the middle of the arc of the steel sheet symmetrically welded together with the light tube to form a fin (rib or butterfly), the front shape is quite like the capital letter "H", so called H-type finned tube (H-fin tube). The two fins of the H-finned tube are rectangular, approximately square, and their edges are about twice times longer than those of the light tube. It belongs to the extended heating sur
The finned tubes of air cooler are mainly: L-type winding finned tube, mosaic finned tube, whole rolling finned tube, composite finned tube (bimetallic finned tube). How to choose the fin material of air cooler bundle fin Tube 1. In the refining and petrochemical industry, the finned material is mostly aluminum. The outer tube of bimetallic generally uses aluminum alloy tube containing silicon manganese, which is helpful to improve the hardness of rolled out fins. 2. In the power industry and other industrie
The Difference Between Single Metal Finned Tube And Bimetallic Finned Tube
Both single-metal finned tubes and bimetallic finned tubes are finned tube types, which are distinguished below. Finned tubes, also known as heat dissipation tubes, are divided into single-metal finned tubes and bimetallic finned tubes. Single metal finned tube is rolled from aluminum tube as a whole, called aluminum rolled finned tube, no contact thermal resistance, high strength, heat and mechanical vibration, goo
Analysis On The Unique Structure Of H-finned Tube
H-type finned tube is divided into single H and double H type, and is widely used as an enhanced heat transfer element in the flue gas waste heat recovery system of power plant boilers, industrial boilers, kilns, ship devices, etc. So why are H-finned tubes so widely used? Because of its unique structure, the construction stability is not easy to deform, high heat transfer efficiency!
Three-roll Oblique Rolling Integral Spiral Finned Tube
The production principle of the three-roll oblique rolling integral spiral finned tube is as: lining a core rod in the light tube, driven by the rotation of the roll blade, the seamless steel pipe through the pore cavity composed of the rolling groove and the core head on the outer surface of the processing of fins. The finned tube produced by this method is an organic whole because of the base tube and the outer fin, so
Development of new type of radiator equipment
Development of new type of radiator equipment The new radiator meeting discussed the development direction, structure, material, system requirements, process and design requirements of the radiator.
The processing of brazing spiral finned tubes is carried out in two steps. First, the steel strip plane is perpendicular to the pipe axis according to the spiral way winding on the outside surface of the pipe, and the steel strip at both ends of the welded pipe fixed, and then in order to eliminate the gap between the steel strip and the pipe contact, the steel strip and steel pipe are welded together by brazing met
