"Composite Repair" is a preventive maintenance measure for reduced-thickness piping that complies with the international standard ISO 24817. Through strength calculations, the optimal repair range and number of layers are determined based on the required service life and purpose. High-quality materials with a maximum design life of 20 years are used, and construction is carried out under thorough management. By repairing with composite "before penetration," the service life can be predicted, thereby avoiding the risk of unexpected equipment shutdowns due to pipe breaks caused by external corrosion. This not only reduces production losses from leaks at penetration points but also facilitates long-term equipment renewal planning after repairs. 【Strengths of Composite Repair】 ■ Design can be tailored to purposes such as strength restoration, leak prevention, and corrosion protection (strength calculations) ■ Preventive maintenance measure for reduced-thickness piping with predictable service life ■ Strength restoration and leak prevention possible with a maximum design life of 20 years ■ Design and construction compliant with ISO 24817 ■ Quality that has passed performance tests by third-party organizations *You can view case studies of construction in thermal power plants and oil refining plants, as well as proposal materials tailored to the purpose of repairs, from the "PDF Download" section.

The composite repair service provided by Fujifilm Pharma Night allows for the repair of reduced-thickness piping through the lamination and repair of composite materials made from carbon fiber and epoxy resin, enabling corrosion prevention, strength restoration, and leak sealing. Strength calculation in composite repair refers to the process of calculating the necessary thickness of composite layers required for repair, taking into account the purpose and conditions of the repair. Based on information from customers and on-site surveys, our company selects appropriate formulas tailored to the damage shape and calculates the "necessary composite thickness." 【What is strength calculation?】 ■ Calculating the thickness of composite layers required for repair, considering the purpose and conditions of the repair (design life, pipe diameter, pressure, temperature, fluid, etc.) ■ When performing strength calculations for the thickness of composite layers that exhibit leak-sealing effects, selecting the appropriate formula from multiple patterns. *For more details, please refer to the PDF document or feel free to contact us.

Corrosion occurred on the 8B piping laid on the upper part of the tank in the oil refining plant, and according to the RT results, it was found that the minimum wall thickness of the 3/4B boss section is 0.6mm. In the event of a problem with the piping, there is a risk of leakage of the internal fluid (butane), and to update the piping, the entire plant must be stopped, making corrosion prevention measures essential before any leakage occurs. Therefore, as a corrosion prevention measure centered around the boss section, a composite was laminated in two layers over a range of 300mm to the left and right of the 8B main pipe. The high environmental barrier effect of the composite layer completely prevents the progression of external corrosion and reduces the risk of leakage compared to measures taken with just anti-corrosion paint. [Effects] ■ The high environmental barrier effect of the composite layer completely prevents the progression of external corrosion. ■ The risk of leakage is reduced compared to measures taken with just anti-corrosion paint. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study from a petroleum refining plant. Rainwater entered the 2B dummy pipe support welded to the 3B elbow inside the petroleum refining plant, leading to corrosion over time and noticeable wall thinning. Therefore, we designed it under the condition of "being usable for 10 years without replacing the target piping" and decided to laminate a composite four-layer structure. The composite layers prevent the progression of permanent corrosion and also consider the future leak-stopping effect in case the thinned areas penetrate within the design lifespan (10 years). 【Strengths of Composite Repair】 ■ Design can be tailored to purposes such as strength restoration, leak stopping, and corrosion prevention (strength calculations) ■ Preventive maintenance measures for thinned piping with predictable service life ■ Strength restoration and leak stopping with a maximum design life of 20 years are possible ■ Design and construction in accordance 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. *We also encourage you to check out the case study materials.

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.

We examined the leak prevention effect when applying primer to stainless steel piping. A pressure test was conducted under the same conditions to compare the leak prevention effects of carbon steel piping and stainless steel piping. It was found that applying primer to stainless steel piping, which cannot undergo surface treatment with electric tools (Bristol Blaster), can demonstrate leak prevention effects. 【Test Piece Details】 ■ Shape: Connecting 1B piping only with a composite layer (PE sheet used for shaping) ■ Number of Layers: 2 layers ■ Surface Treatment ・ Carbon Steel Piping: Electric tools ・ Stainless Steel Piping: Primer *For more details, please download the PDF or feel free to contact us.

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.
