Product Description
High Frequency Resistance Welding HF Finned Tube with Zinc or Aluminum Metallized Ends
high-efficiency heat transfer element with spiral fins. The extended surfaces (fins) can be solid or serrated and have up to tens
of times more heat transfer area than a bare tube.
HF Finned Tube is a spiral winding of steel fins, which is continuously welded on the steel pipe by high frequency resistance
welding (HFERW). A high-frequency current is introduced into the workpiece, the welding contact surface is melted or semi-melted
by resistance heat, and then appropriate pressure is applied to the welding contact surface to complete the welding of the finned
tube. This produces a uniform, clean and continuous finned tube combined with no additional welding material for very efficient
heat flow and corrosion resistance.
High-frequency welded spiral finned tube is one of the most widely used spiral finned tubes.

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.

Superheated Saturated Steam Upper Drum Boiler ASME 2017 Edition
ASME Standard 100mm Thickness Produce Superheated And Saturated Steam Boiler Drum Product Description A steam drum is a standard feature of a water-tube boiler. It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam
