Fujifarmanite was established in 1978 as a specialized company for leak repair through a joint venture between Fuji Electric Construction Co., Ltd. (now Fuji Electric E&C Co., Ltd.) and the British company Farmanite. The "Leak Seal" provided by Farmanite addresses leaks of various fluids (steam, air, oil, gas, etc.) in heat sources, power sources, and product manufacturing processes, and is widely used across various industrial sectors. From the perspective of plant maintenance, we have also launched new services such as "Composite Repair," aimed at restoring the strength of thinned pipes, and "Farmaise," which opens stuck valves due to vibration. Our excellent technicians provide high-quality services using the unique technology of the British company Farmanite.
