Thorough verification of leak prevention performance under harsh construction conditions using composite repair.
We offer services that can be expected to restore the strength of reduced meat piping, stop leaks, and improve textile effects!
The state of the 3B piping is broken, which is considered a missing part. We will consider repairs under the condition that the required durability of the equipment is 1 year, and we created two patterns of test specimens, conducting pressure tests on each. The required number of layers based on the design for a durability of 1 year is as follows: if we can achieve 7 layers with a 50mm overlap and 5 layers with a 150mm overlap, we demonstrated sufficient leak-stopping effect even under harsh construction conditions. [Verification Results] ■ Overlap 50mm - Number of layers: 7 - Result (MPa): 3.0 (leakage occurred at 3.0MPa during pressurization) ■ Overlap 150mm - Number of layers: 5 - Result (MPa): 5.0 (no leakage at 5.0MPa) * Testing was concluded at 5.0MPa due to the risk of piping breakage. * For more details, please download the PDF or feel free to contact us.

Company information
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.
