ASTM B1111 Carbon Steel Boiler Spiral GB Standard Boiler Fin Tube With U Bends

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.
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.

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.
