SGS Welded Seamless Longitudinal H Fin Tube non ferrous alloys

SGS Welded Seamless Longitudinal H Fin Tube non ferrous alloys

Product Introduce

The fin tube can be divided into two basic types: longitudinal type and radial type. Other types are the development and deformation of these two types. For example, the shape of large helix angle fin tube is close to the longitudinal type, and the shape of small helix angle fin tube is close to the radial fin tube has circular, rectangular and needle shape. In addition, the fins can be arranged outside the tube, which is called the outer fin tube, or inside the tube, which is called the inner fin tube or both. H-type tube, has a high rate of fusion welds and weld tensile strength. There is little contact resistance, and heat transfer performance and scalability are additional advantages. The H-fin tube is assembled with the H economizer, which has high efficiency, low resistance, and light weight. Compared to the traditional fin tube or spiral tube the H-fin tube can greatly expand the heating surface. When the extent of the effect of heat transfer is the same. The H-fin tube economizer takes up less space. In addition to the H economizer, H superheater, H air heater, and many other products. The H-fin tube has been included in the “Chinese high-tech product catalog”

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.

Advantages

1.Anti - corrosion

2.Anti-wear

3.Low contact resistance

4.High Stability

5.Ability to prevent accumulation of dust

Structure

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.
