[Composite Repair Case Study] Fire Hydrant Reduced Thickness Pipe Penetration and Leak Repair
Composite materials made of carbon fiber and epoxy resin to avoid the risk of pipe bursts and unexpected shutdowns at power plants! *Examples of construction at thermal power plants are introduced with photos.
Here is an introduction to a construction case study at a thermal power plant. Galvanic corrosion occurred due to the welding of dissimilar metals in the fire hydrant piping. Thinning progressed near the weld line, resulting in a state of penetration and leakage. Our company designed under the condition that "the target piping can be used for 20 years without replacement." When calculating the strength assuming that thinning progresses and the entire circumference of the weld line breaks, it was found that a composite of 15 layers is necessary to suppress leakage. Due to the composite layers, the fracture mechanism changes, which reduces the risk of pipe rupture and helps avoid human casualties and unexpected shutdowns of the power plant. **Strengths of Composite Repair** - Design can be tailored to purposes such as strength restoration, leak prevention, and corrosion protection (strength calculations). - Preventive maintenance measures for thinning piping with predictable service life. - Strength restoration and leak prevention with a maximum design life of 20 years are possible. - Design and construction comply with ISO 24817. - Quality that has passed performance tests by third-party organizations. *For more details on this method, "Composite Repair Service," please refer to the PDF materials or feel free to contact us.
