Carbon Steel/Stainless Steel/Alloy Boiler Fin Tube for Heat Exchange Efficiency
Product Description
The spiral finned tube is a highly efficient heat transfer element with spiral-shaped fins. Its heat transfer area is several times to dozens of times that of the plain tube, which can strengthen heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operation reliability of heat exchange equipment. Spiral finned tubes have been widely used in various boilers. Spiral finned tubes can be manufactured by a variety of methods, and the finned tubes used in boilers, pressure vessels and other heat exchange equipment mainly have the following manufacturing methods: high-frequency resistance welding spiral finned tubes, brazed spiral finned tubes and integral spiral finned tubes.
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 |
| Thermal insulation &Surface treatment | according to customers specification |
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.
Advantages
1.Anti - corrosion
2.Anti-wear
3.Lower contact resistance
4.High Stability
5.Ability to prevent ash accumulation
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.
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. |
