Spiral fin tube economizer is squeezing by high frequency welding method and the technology of steel strip according to certain structure automatically, continuous spiral welding outside the light tube wall, and then the other reserved part light tube bending, combination according to the requirement. As a result, the diameter and length under the same conditions, it has larger heat transfer area.
Integral Spiral Finned Tube economizer is mainly used as heat exchange element
Due to the expanded heat transfer area, economizer tube row number decreases, thus reducing the possibility of the welding work and solder joint leakage, improve the safety and reliability of the pressure parts Heat transfer condition in the same conditions, its weight is lighter, about 70% of the light tube economizer, the materials about 45% of the light tube economizer;
3) L ower contact resistance
4) Higher Stability
5) Anti- dust
Testing and acceptance standard:
JB/T6512 "boiler with a high-frequency resistance welding spiral fin tube manufacturing technology conditions";
HG/T3181 "high-frequency resistance welding spiral fin tube";
JB/T6511 "spiral finned tube box assembly conditions";
JB/T1612 "boiler pressure test technical conditions."
JB1611 "boiler tube manufacturing conditions."
JB16I3 "boiler pressure parts welding conditions.
For quality control, Integral Spiral Finned Tube manufactured by the Company has been examined, approved, and certified by several national authorities. The company quality management was also ISO9001 certified.
We design and manufacture as per national standard and company standard, or International standard such as ASME, and also as per customer specific requirements.
