Carbon Steel Boiler Spiral Fin Tube with U Bends in GB Standard for Various Boilers Appllication
Product Description
Hua Dong Boiler is dedicated to the production of boiler fine tubes, which are part of an economizer. Our fin tube is an ideal method for increasing the heating surface of boilers, and improving boiler heat transfer efficiency.
We provide custom boiler fin tubes for industrial boiler manufacturers and boiler accessories suppliers. Corresponding processing services like welding and assembling are also available.
General introduction
Spiral finned tubes are widely used in heat recovery of boiler economizer, air preheater, and waste heat boiler, as well as heat exchange equipment in chemical industry, pressure vessel and other fields. The capacity of units used in boilers has also increased from small to large, and their applications are increasing day by day. At present, many professional manufacturers in China can produce high frequency resistance welding, brazing spiral finned tubes, and the production equipment and technology of finned tubes have been developed, designed and manufactured from importation, digestion and absorption to self-development. The quality has reached the requirements of advanced foreign standards.
Advantages of using finned tubes:
1. the heat transfer area is increased in the effective space to improve the heat transfer effect.
2. Reduce the occupancy space of heat transfer surface and reduce its volume, especially for fast-loading boilers.
3. Reduce the equipment cost and improve the safety of equipment.
4. Due to the decrease of water side pressure drop, the operation cost is reduced.
5. The stiffness of finned tubes are increased, and the seismic resistance of the tube is improved.
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. |
