ISO / ASME Standard Spare Part Double H Type Boiler Fin Tube Heat
Exchange
Product Description
The finned tube is a heat exchanger.Is to improve the heat exchange
efficiency, usually in the heat exchange pipe surface by adding
fins, increase the heat exchange pipe surface area (or internal
surface area), so as to improve the heat exchange efficiency, such
a heat exchange pipe.
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.
Technical parameter
| Medium | air, flue gas, thermal oil, water, brine, refrigerant, etc. |
| Temperature | standard heat exchanger to 560 ° C by special materials can be higher |
| Pipe materials | carbon steel, stainless steel, alloy or special materials |
| Ribs materials | carbon steel, stainless steel, non-ferrous metal, alloy or special materials |

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
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.
Quality Control
| 1 | Impact test and Strength calculation report with applied materials information. |
| 2 | 100%NDT(non-destructive inspection) report of steel plate, tube and electrode. |
| 3 | X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler. |
| 4 | Hydraulic test report: ensure the standard working pressure and
safety. |
