Double H Boiler Fin Tube For Boiler Spare Parts , Heat Exchanger Boiler Water Tube

Advantages of H-type finned tube:

一．耐磨损

Wear resistance

1)耐磨损,可提高磨损寿命3-4倍.

1) Wear resistance, can increase wear life 3-4 times.

实验发现,顺列布置螺旋翅片管磨损有如下规律:

It is found that the wear of spiral finned tubes arranged in line has the following rules:

(1)磨损发生在螺旋前进方向一侧；

(1) Wear occurs on the forward side of the screw;

(2)磨损严重部位发生在螺旋前进方向一侧, 靠近翅片皱折处管子根部附近区域

(2) Severe wear occurred on the forward side of the helix, near the root of the tube at the fin fold

这是由于螺旋翅片的旋转,螺旋翅片旋转形成的翅片表面是一个空间曲面,肋片加工过程中形成的皱折所造成的.

This is caused by the rotation of the spiral fins, the surface of the fins formed by the rotation of the spiral fins is a space surface, and the wrinkles formed during the processing of the fins

而H型鳍片管鳍片笔直,即不旋转,表面平行气流和加工不形成皱折,故可以克服螺旋翅片管的磨损严重问题；H型鳍片将空间分成若干小的区域,对气流有均流的作用,在其他条件相同的情况下,磨损寿命高3-4倍.

However, the h-fin tube is straight, that is, it does not rotate, the surface is parallel to the air flow and the processing does not form wrinkles, so it can overcome the serious problem of the wear of the spiral fin tube; the h-fin divides the space into several small areas, which has the effect of current sharing on the air flow, and the wear life is 3-4 times higher under the same other conditions.

Product Description

H-fin Tubes have two steel discs,with fluorescent tubes symmetrically welded together to form fins(fins of butterfly piece)creating a shape that looks somewhat like the letter"H",creating an efficient energy saving, extension heating surface.

H-fin Tubes also have a high rate of fusion welds and weld tensile strength.H-fin Tube is assembled with the H economizer, which has high efficiency,little resistance,less wear and light weight.

Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
 

Specifications

1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.
