Long-term extension of meat reduction piping with 'Composite Repair' *Presentation of construction case materials
Repairs are made according to the necessary durability years and purpose (strength restoration, leak prevention, corrosion protection). It allows for predicting maintenance timing and is suitable for permanent plant maintenance!
"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.

basic information
For repairs of areas with reduced thickness, measures such as repainting, FRP wrapping, and iron cement are often used. However, with simple measures, it is difficult to predict the service life, and many may be anxious about when a leak might occur. If a leak occurs from a reduced thickness area, not only will production stop, but it will also incur costs and time for recovery. Therefore, preventive maintenance is crucial for areas that are prone to thinning. Please consider 'Composite Repair,' which allows for a clear understanding of service life and optimization of long-term plant maintenance. *For more details, please refer to the PDF materials.

Detailed information
-
We use a composite material made of lightweight carbon fiber with excellent tensile strength that does not corrode, and epoxy resin with superior adhesion and low permeability to oxygen and hydrogen.
-
[Repair Case 1] Before Construction: Corrosion occurred in the fire hydrant piping within the thermal power plant.
-
[Repair Case 1] After construction: Designed under the condition of "usable for 20 years." Although the design conditions differed from expectations, we responded flexibly on-site.
-
[Repair Case 2] Before construction: Corrosion of piping inside the petroleum refining plant due to rainwater intrusion.
-
[Repair Case 2] After construction: Designed under the condition of "usable for 10 years." Measures for future leak prevention are also implemented in case of penetration at reduced thickness areas within the design lifespan.

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.
