This is a type of repair and reinforcement joint that utilizes existing flexible joints and pipe fittings as they are, covering the target object from the outside. It employs wedge-shaped rubber in the airtight section, allowing for flexible adaptation to expansion, bending, twisting, and eccentric displacement after installation, ensuring high water-tightness. Additionally, the use of wedge-shaped rubber in the airtight section allows for a structure that can accommodate the flattening of pipes, making it ideal for permanent repairs of aging large-diameter pipes and flange areas. It requires no water stoppage and can be installed in a short time, with numerous applications in the maintenance and renovation of aging piping in power plants and plant facilities. *For more details, please download the PDF or feel free to contact us.*

This product allows for repairs and reinforcements from the inside of large-diameter piping, such as seawater supply pipes and cooling water lines. It features a slim design that minimizes the impact on fluid flow and pressure loss within the piping after installation. Additionally, it can be custom-made to flexibly accommodate expansion, eccentricity, vibration, and slight pipe displacement, making it ideal for extending the lifespan of aging equipment and streamlining piping maintenance. It has a proven track record as an internal repair joint that enables quick installation and permanent repairs in power plants and plant maintenance sites. *For more details, please download the PDF or feel free to contact us.*

This is an internal repair and reinforcement joint designed for large-diameter piping such as seawater supply pipes and cooling water piping. It can be applied from the inside to address corrosion, leakage, and aging deterioration of the piping. Once installed, it can be used permanently and flexibly adapts to deformations of the piping such as expansion, bending, twisting, and eccentric displacement. It is widely adopted as a measure for updating aging piping in power plants and plant facilities, reducing maintenance costs, and extending lifespan. *For more details, please download the PDF or feel free to contact us.*

The RJF type developed by our company enables permanent repairs for piping leaks and flange leaks without the need for equipment shutdown or water supply interruption, even while in operation. It is not a temporary repair; it can also accommodate high-pressure piping, seawater piping, and SUS piping in high-pressure and aging plant facilities. Additionally, it contributes to short construction times and cost reduction, and is widely adopted for piping maintenance in power plants and for the renewal of aging piping. *For more details, please download the PDF or feel free to contact us.*

Install a split-type band on the existing closure joint and secure it with a centering bolt. By using it mainly on existing closure joints for the upper part of the water pipe bridge, the amount of expansion absorption of the joint is doubled, fulfilling its role as a seismic isolation joint. *For more details, please download the PDF or feel free to contact us.

When an earthquake or ground subsidence occurs, displacement occurs in the piping. If the displacement progresses, there is a possibility that the piping will be damaged, leading to leaks. To absorb the displacement, it is necessary to install flexible pipes. In such cases, it is required to cut and remove part of the piping and connect the flexible pipes by welding, which takes a lot of time. This product does not require welding, allowing for quick installation. It absorbs expansion, eccentricity, and twisting, and provides permanent water-stopping performance. *For more details, please download the PDF or feel free to contact us.*

Typically, when a mechanical joint experiences water leakage, the common method is to shut off the water supply and replace the joint. However, our developed RJ allows for leak repairs without the need for a water shutdown, which was previously essential. The installation is simple and does not require any special techniques. After the repair, it absorbs expansion, bending, and twisting, demonstrating high durability. *For more details, please download the PDF or feel free to contact us.*
