Two rows of parallel fin tubes are arranged at the front side of the plug header. The rear end of fin tube is set in the reserved hole in front of the plug header box. The rear side of the pipe box is arranged with two rows of parallel plugs holes in the fin tube. The plug and gasket are located at opposite side of each tube, then allows operators to do inspection , cleaning and maintenance for individual tubes.
If any leakage of tube was found, then new spare plugs and gaskets will be needed to replace the original ones during routine maintenance.
As a professional fin tube manufacturer, we can not only supply fin tubes, but we can also supply spare parts for the fin fan cooler, such as header, transition nozzles, plugs and gaskets. So we are a one-stop supplier in the fin fan cooler industry.
Usually the plug material is soft Iron SA105 and gasket material is A366. But according to different operation situation of air fin fan cooler, other material of plugs and gaskets will be used, such as stainless steel, brass, titanium, nickel alloy, etc.
After plugs and gasket formed to required size, the surface is usually with zinc coated, whether being white zinc or being with colorful zinc. (when plug material is SA105).
When plug material is SA-182 F316L, then gasket material is SS316L.
When plug material is SB-654 UNS N08825, then gasket material is SB-162 UNS N02201.
The material for plugs and gasket is usually determined by the fin tubes material, fin tube material and fin type then decided by the working environment of whole fin fan cooler.
