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.
Manufacturing method
Spiral finned tubes can be manufactured by various ways. At present, there are several main manufacturing methods for finned tubes used in heat exchangers such as boilers and pressure vessels.
High frequency resistance welding spiral finned tube
High frequency resistance welding spiral finned tube is kind of high frequency current imported into the welded parts. By using the resistance heat generated by the current through the contact surface of the welded joints and adjacent areas, the welded contact surface can reach the plastic state of melting or semi-melting, then appropriate pressure is applied to the welded contact surface, to complete welding work of finned tubes.
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. |
