Extruded Embedded Type Longitudinal Spiral Square Heat Exchanger Coil Aluminium Copper Fin Tube

H-economizer two rectangular fin, similar to a square, its edge length for the fluorescent tubes of 2-fold, an expansion of the heating surface. H-economizer flash resistance welding processes used, the welding seam after the high rate of fusion, weld tensile strength, and has good thermal conductivity. H-economizer can also manufacture dual tube "double H" type fin tubes, its rigid structure, and can be applied to a longer tube row occasion.

The advantage of the square fin tube:

• Increase tube outside surface and improve heat transfer efficiency.
• Reduce the number of tubes arranged for the heat exchanger equipments than bare tube.
• Reduce the flue gas velocity and reduce the wear rate and prolong the life-span for the equipment
• H type fins have the best soot blowing effect due to the formation of straight passages on both sides
• Can offer larger surface area than spiral finned tubes

Tube ends are cut with free burrs, internally dried and air-blown clean, externally coated with varnish Jinbes has two production lines for the H type finned tube and HH type finned tube. We also have three sets of cutting machines to cut the finned tubes into different length according to customers’ requirements. If you have any futher design requirements, welcome send us your technical drawings, we can provide our solution for your reference and will try our best to support you.

Description: 

 
Acceptance Criteria

Specifications:
 

 
Competitive Advantage:

1. We have more than 10,000 square meters workshop, including 6 H-FIN TYPE finning machines, daily extrusion capacity up to 20 tons.
2. The Square or Rectangular Fins H-Finned Tubes are the preferred tube choice for high pressure boilers. 
3. Fins can be manufactured by stamping process in almost any shape and size.
4. In-line fin and tube spacing allows for cleaning with excellent choice in sooting or fouling atmospheres.
5. Fin height and spacing are limited only by heat transfer considerations.
6. Fins and tubing can be similar or dissimilar metals.
