Boiler Spiral Fin Tube Solid With Curved Arrows For Serpentine Economizer ASME Standard

Boiler Spiral Fin Tube Solid With Curved Arrows For Serpentine Economizer ASME Standard

Product Description

High finned tubes are also called extruded tubes. The finning is achieved by extruding the fin from the tube.

Extruded tubes can be either from one piece or from 2 different materials (bimetallic).
 

The inner tube material is usually anticorrosion one, but tubes made from carbon steel, alloy steel, stainless steel or copper or titanium alloys can be used as well.

Extruded tubes made from one piece are manufactured by cold rolling of base tube usually from copper or aluminium alloys. Tubes can also be manufactured from carbon and stainless steel.

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.
 

1.Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.

2.Fins are used to increase the effective surface area of heat exchanger tubing.

3.Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas,vapor to a gas ,such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.

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.
