What is a Finned Tube ，Durable Finned Tube
Finned Tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving heat exchange efficiency. Such a heat exchange tube.
the Laser Welded Stainless Steel Finned Tube radiator for boilers is a device that adds fins to the base tube. The Finned Tube Heat Exchanger adopts convective heat dissipation, and the medium is generally water, steam, and heat transfer oil. The finned tube Heat Exchanger uses seamless steel pipes for welding.Durable Finned Tubes .The medium of high-frequency Welded Finned Tube radiators is generally water, steam, and heat transfer oil, but poor water or industrial wastewater will reduce the service life of the radiator, so we should choose water with better water quality as the heat transfer medium of the radiator On the one hand, it improves the heat dissipation efficiency of the radiator,Durable Finned Tubeand on the other hand, it can also prolong the service life of the radiator. If the user takes good care of the laser welded Stainless steel finned tubes, the life of the radiator can reach 30-50 years. Finned tube radiators can be processed according to people's different needs, and can be divided into hundreds of models according to tube length and tube diameter. Among them, the tube diameter can reach 6 inches, and the Tube length can be processed according to people's needs.Durable Finned Tubes.The connection method of connection or screw connection, the connection method is reliable and will not leak easily.
The carbon steel laser-welded spiral Fin Tube adopts a fully automatic welding process, which not only saves labor costs, but also passes the test of the firmness and tensile strength of the Laser Welded Fin. Laser welding has the advantage of higher efficiency. Laser Welded Finned Tubes have a longer service life and the welding process is fully automated. Carbon steel laser welded finned tubes are welded from carbon steel. Because the traditional welding process has its insurmountable shortcomings. The technological content and quality of laser-welded spiral finned tubes are superior to traditional cooling tubes.Durable Finned Tubes.
Advantages of Laser Welded Finned Tubes
a. Laser welding finned tube (Finned Tube) fin machine has a high degree of automation, and the welding of fins and tubes is synchronized with the winding of tubes
b. 100% welding rate, laser welding of finned tubes and fins is strong, and the welding strength exceeds 600MPa.
c. The accuracy of the laser welding tube finishing machine can reach 0.5mm
d, 0 contact resistance, high-efficiency heat transfer of spiral finned tubes is realized by laser welding.
e. Save production cost. The fin spacing of laser welded finned tubes (finned tubes) is small, less than 2.5mm. Compared with high frequency welded spiral (helical) finned tubes, the heat transfer area is increased by about 50%, which makes the material cost lower and the volume of the heat exchanger smaller.
f. The thinnest base pipe wall thickness that can be used by laser welding process is 1.0mm, and the thinnest fin is 0.4mm.
Finned tube radiator is a new type of heating equipment in recent years, mostly used for heat dissipation in large heating places. Finned tube radiators are divided into steel finned tube radiators, aluminum finned tube radiators, etc. according to different materials; tube radiators, etc. There are many models and types of finned tube radiators, how should we choose?
First of all, we need to know what the working environment of our place is, whether it is high temperature and high pressure, strong corrosiveness, or dusty. After determining the use environment, we need to know the area, height, width and other large dimensions of the place of use and the heating temperature we need to achieve.
Secondly, after we understand our specific needs, we can better choose finned tube radiators. For example, in a dusty environment, we need to choose a finned tube with a larger spacing, generally around 10m. In some places with less dust, we can choose a finned tube with a smaller spacing, generally 8mm. When we choose finned tubes, we can also consult professionals to choose a reasonable radiator according to our own needs.

What is a composite Laser Welded Finned Tube?
Finned tubes are slender flat tubes made of aluminum clad carbon steel with brazed aluminum fins. These tubes are used in series for the heat exchanger. Their advantage over normal tubes is that the fins have greater contact with the external liquid. This accelerates the heat exchange between the liquid inside the tube and the liquid outside the tube. With normal tubes, the rate of heat transfer will be much slower.
There are different shapes of Finned Tubes.
What is the use of Laser Welded Finned Tubes?
Finned tubes are particularly useful in the case of air heat exchangers. In an air heat exchanger, heat transfer occurs between a liquid and a gas. Finned Tubes are useful due to the lower thermal coefficient on the air side. Finned tubes increase surface area, which facilitates faster heat transfer between components.
Advantages of using Finned Tubes
Finned tubes have the following advantages:
Improve heat transfer rate
The fins in the Finned Tube increase the contact surface area. This enables it to speed up heat transfer.
Improve heat transfer coefficient
Classification of Finned Tubes
Durable Finned Tubes
There are many types of finned tubes, and new varieties are constantly emerging. In general, it can be classified according to the following aspects:
1. Classified by processing technology
1), extruded fin tube (extruded fin tube);
2), welded finned tubes (High Frequency Welded Finned Tubes, submerged arc welded finned tubes);
3) Roll forming finned tubes;
4), suit forming finned tube;
5), cast finned tube;
6), tension wound Finned Tube;
7), insert Tube.
Classified by fin shape
1) Square finned tube;
2), circular finned tube;
3) Spiral Finned Tube;
4. What is fin welding?
In finned tube welding, a rolled steel strip is continuously welded in a helical pattern on the outside diameter of the tube. The welds produced in this process are true forged, blacksmith welds. This type of weld consists of fusion between two parts of the parent metal without the introduction of filler material.
