Stainless 304 Economizer Spiral Fin Tube For Hot Water Boiler , Energy Efficient

Stainless 304 Economizer Spiral Fin Tube For Hot Water Boiler , Energy Efficient

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.

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.

Technical Parameter

Quality Control:

1. Strength calculation report with applied materials information;

2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;

3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;

4. Hydraulic test report: ensure the standard working pressure and safety
