Product Specification

Spiral Square Longitudinal ERW Fin Tubings Fintubes Fin Pipes Finned Pipes

The high frequency fin tube produced by our company can be applied to boiler economizer, air preheater, chemical crystallizer, etc. The main products: high-frequency spiral resistance welding fin tube, stainless steel fin tube, double metal steel aluminum compound pipe, copper aluminum compound tube, cold and hot coil heat exchanger. Products are widely used in petrochemical, electric power, metallurgy, building materials, coating, boiler, heat carrier air conditioning, refrigeration heat conduction oil furnace, pressure vessel, dryer, intelligent greenhouse, livestock farming, fin tube economizer and air preheater, etc.

Manufactured in the same way as the L fin-type expect that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments

H fin tube known as square fin tube, There are two type of H fin tubes, one type with single tube, normal called square fin tube, the other with Double tube, normal called rectangular fin tubes. and also manufactured as per customers requirements. Due to rectangular shapes, which can offer large surface area compared to the Spiral Finned tubes. Due to larger surface area available, these finned tubes are used mostly in Air Heating application to reduce the overall size of the equipment.

H fin tube is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shap much like letter "H", so called H-fin tube. H-economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.

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.
