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.
