Customized Carbon Steel Spiral Boiler Spare Parts Fin Tube for Industry

Product Introduction

Spiral fin tube is a kind of high efficiency heat transfer element with spiral fin.
Its heat transfer area is several times to dozens of times of the light tube, can strengthen heat transfer, reduce flow resistance, reduce metal consumption, thus improving the economy of heat exchange equipment and operating reliability.
At present, spiral fin tube has been widely used in various boilers.
Spiral finned tube can be manufactured by various methods. At present, there are mainly the following manufacturing methods for the finned tube used in heat exchange equipment such as boilers and pressure vessels: high-frequency resistance welding spiral finned tube, brazing spiral finned tube and integral spiral finned tube.
The manufacturing method, performance evaluation index, application and advantages of integral spiral fin tube are introduced in detail.

Features

1) The heat transfer area is increased in the effective space to improve the heat transfer effect.
2) Reduce the occupied space of heat transfer surface to reduce its volume, especially suitable for quick loading boilers.
3) Reduce equipment cost and improve equipment safety.
4) The operation cost is reduced due to the reduction of water side pressure drop.
5) Increased fin tube stiffness, improve the seismic resistance of the pipe.

Advantages

The spiral finned steel tubes used now are mostly spiral finned steel tubes of winding type, high frequency welding type and brazing type.
The integral spiral finned steel tube, with its long service life, stable heat transfer performance and obvious energy saving effect, has become the replacement product of the above three forms of spiral finned steel tube. Its advantages are shown in the following aspects:
1. Long service life, which is more than 3 times of the wound and welded finned steel pipe.
2. The finned root and the pipe are arc-cut, and the finned surface is smooth, completely eliminating the phenomenon of ash accumulation, blockage, and slag formation caused by the unfoldable finned root of other finned pipes.
3, the use of hot rolling rolling process, improve the metal structure of the density, yield strength, tensile strength and wear resistance.
4. As the fin and the pipe are integrated and distributed in spiral bands, the overall bearing capacity of the spiral finned steel pipe is more than 3 times that of the seamless steel pipe with the same wall thickness and inner diameter.
5, wear resistance, to solve the coal-fired boiler convection heating surface due to high wind speed, ash concentration wear serious problems.
(especially circulating fluidized bed boilers)
6, fin and tube as one structure, completely eliminate the other forms of fin steel pipe fin and tube as a two-body structure can not overcome the contact thermal resistance, and fin longitudinal section of the trapezoidal structure, so as to maximize the fin heat transfer efficiency.
7. The integral spiral fin extended surface heat transfer is adopted. Under the same working condition, the heat transfer coefficient of the tube bundle is 3.5-5.5 times of the seamless steel tube of the same wall thickness and inner diameter, and 2 times of the welded spiral fin steel tube of the same specification.
8, the fin and the pipe as a whole structure, so used for high temperature, bad environment of the work place, will not occur in other forms of fin steel pipe due to fin relaxation, falling off caused by unstable heat transfer performance phenomenon.
