Best impact force resistant and work reliability boiler economizer spiral fin tubes

Specification:

Best impact force resistant and work reliability boiler economizer spiral fin tube is the most widely used of the spiral finned tube, widely used in electric power, metallurgy, cement industry preheating collection and petrochemical industries. Boiler economizer spiral fin tube is welded steel strip coil pipe at the same time, using high-frequency currents of the skin effect and proximity effect of steel tube, and surface heat until melted in the plastic state or steel strip coil, the complete welding under certain pressure. This kind of high frequency welding as a solidphase welding. It with Mosaic, brazing (or whole galvanized) method, whether in product quality (fin of weld rate is high, of 95%), or the productivity and automation degree, are more advanced.

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

Introduction:

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 economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.

3. With straight channel to gain the best ash-blowing effect.

4. The compact structure to reduce the weight and reduce the manufacturing cost.
