Application of bimetal rolled finned tube

Heat exchangers are primarily made up of finned tubes. They are a series of tubes with fins on the outside to increase contact area with the outside fluid, exchange heat, and exchange fluid between the fluid inside the tube and the fluid outside the tube. Finned tubes are carbon steel flat tubes that have been clad in aluminum and have brazed aluminum fins.

Finned tubes come in a variety of shapes and sizes, including round tubes, oval tubes, and flat tubes. Flat tubes, so-called SRC, are the state-of-the-art for power plant air cooled condensers. They are made of aluminum clad carbon steel tubes with aluminum brazed fins.

The fining ratio of the bimetal rolled fin tube/steel-aluminum composite fin tube is between 13.5-22.7, which can meet the needs of various process conditions. The bonding rate is more than 90%, and the temperature inside the tube is less than 210 degrees for a long time. There is no attenuation of the heat exchange power in the working environment for a long time. The companys products are divided into two categories, industrial and civil. Various types of finned tubes, heat pipe heat exchange elements and air heaters, coolers, various boiler economizers, heat pipes and finned tube waste heat recovery equipment, iron and steel professional sintering waste heat boilers, lime kiln air, gas preheating Air heaters, blast furnace hot blast stoves, separated and overall heat pipe air, gas preheaters, power plant heaters, household radiators and other drying and heating equipment and other products.

The most commonly used finned tube for heat exchange with air is the Bimetal composite Extruded finned tube. First, a certain thickness of aluminum tube is tightly set on the base tube, and then the aluminum tube is rolled by rolling machine to remove the spiral fins, forming a tightly structured bimetal composite rolled finned tube.

The benefits of the Bimetal composite Extruded finned tube include: low contact heat resistance, long life, smooth fin surface, complete isolation of the base tube from the heat exchange medium, not easy to scale, easy to clean, and the ability to maintain good heat transfer performance for an extended period of time. Carbon steel, stainless steel, titanium, purple copper, and other materials can be used for the base tube.

Bimetal composite extruded finned tubes are widely used in air conditioning, air cooling, power plants, petroleum, chemical industry, and other heat exchange equipment.
