Product Description

Alloy Steel H fin tubes/ boiler economizer for water heating /energy saving

 

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.
 

Technical parameters	The high degree of fin 0-16mm(or outside diameter of fin φ25-φ75); Pitch of fins 2.0-5.0mm; Length of finning tube 0.5~ 14m.
Single metal rolling finning tube	Pure aluminum 1060 or aluminum alloy 6063,6061. Outside diameter Shall be less than 40mm
Double metal rolling finning tube	Tube-based protection from the outer layer of aluminum tubes,corrosion-resistant,Tube-based can be made of carbon steel pipe,in addition to,stainless steel tube and copper tube can also be used, as well as titanium alloy tube
Package	The aluminum finned tubes are well packed in plastic film in the inner and steel fram in the outer

 

Manufacture

 

High frequency and high frequency welding spiral finned pipe is one of the most widely used spiral finned pipe at HDB.It is widely used in power, metallurgy, cement industry waste heat recovery and petrochemical industry.High frequency welding spiral finned pipe is in the steel belt winding steel pipe at the same time

, using the skin effect and proximity effect of high frequency current, the steel belt and the outer surface of the steel pipe are heated until the plastic state or melting, and the welding is completed under certain pressure of the wound steel belt.This high frequency welding is actually a solid phase welding.Compared with Mosaic, brazing (or overall hot dip galvanizing) and other methods, it is more advanced in product quality (fin bonding rate is high, up to 95%), productivity and automation.

 

 

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.
