Carbon Steel Titanium Spiral Finned Tube Coil For Boiler Economizer
Product Introduction
Compared to the traditioanal fin tubes or spiral tubes the H-fin tube can greatly expand the heating surface. When the extent of the effect of heat transfer is the same .
The H-fin tube economizer takes up less space. In addition to the Heconomizer, Hsuperheater ,H air heater, and many of other products, The H fin tubes has been included in the “Chinese high-tech product catalog”.
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.

Product Description 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. Details 1.Our products can be modified according to our customers' needs and the situation. 2.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems. 3.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space. Technical parameter
Features 1. The equipment body can be designed into many modules to ensure the long term and stable running; 2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage 3. Improve the heat transfer efficiency 4. Structure arrangement: In line or staggered arrangement | |||||||||||

Test
| 1 | Latest type of 'U' bending machine is used for precision cold bending of tubes. |
| 2 | Bending is done for all kind of heat exchanger, condenser, economizer, boiler tubes in Stainless Steel Seamless as well as welded. |
| 3 | Subsequent to 'U' bending tubes are hydro tested & stress relieved if asked for. |
| 4 | Also mock-up pieces are prepared for determining thickness reduction on the bend portion. |
| 5 | Dye penetrant testing on the bend portion is done ro detect cracks, flaws or any type of defect. |
| 6 | Special packing is provided to prevent any damages during transit. |
