Understanding the condition of buried pipes requires a significant amount of time and cost for excavation. This has become a major challenge during disasters, where rapid situational awareness is essential. The Vixensor (displacement measurement device for joints) allows for immediate assessment of the condition of buried pipes without incurring such time and costs. It is currently widely used in airports, water supply systems, and agricultural water. 【Purpose of Installation】 - In the event of disasters such as earthquakes, accurately knowing the expansion and eccentricity of flexible joints enables prompt and precise countermeasures. - By accurately understanding the current state of the expansion and eccentricity of flexible joints, as well as the current situation of ground subsidence and uplift, it can be utilized as fundamental data for promoting seismic resistance. - Based on the displacement measurement results, establish the priority of reinforcement plans in the medium to long term. *For more details, please download the PDF or feel free to contact us.

Due to the effects of ground subsidence, earthquakes, temperature expansion and contraction, various stresses are applied to the piping, which can lead to water leaks and pipe disconnections. Closure joints are most suitable for alleviating such stresses and absorbing displacements. Because the structural reaction force is small, the impact on the piping and structures is extremely minimal. With long-lasting and stable airtightness, as well as significant performance in absorbing expansion, eccentricity, and twisting, they are widely used, particularly in the fields of water supply, electricity, and plants. ● Absorption of displacements after piping - Uneven subsidence - Bending - Twisting - Temperature expansion and contraction - Piping vibration *For more details, please download the PDF or feel free to contact us.

The flexible expansion joint for large diameters (φ2400 and above) had economic issues due to the structure of its airtight mechanism. Therefore, the Multi-Def was developed for large diameters. We succeeded in changing the structure of the automatic rubber ring, allowing for the economical and reliable absorption of expansion and eccentricity in large diameter piping. It is used in water supply pipes for drinking water and cooling water pipes for power plants. *For more details, please download the PDF or feel free to contact us.*

This product is an "adjustable expansion joint" that allows for manual fine-tuning of pipe lengths. It makes it easy to adjust the position of the main pipe when attaching or detaching equipment such as valves, pumps, valve bodies, and flow meters, significantly reducing the burden of pipe renewal and maintenance work around machine rooms and equipment rooms. After installation, it is also expected to improve the pipe's ability to absorb expansion and enhance seismic performance, making it ideal for the maintenance of piping in power plants and facilities where earthquake resistance and thermal expansion measures are required. It also contributes to reducing water outage times, improving work efficiency, and lowering maintenance costs. *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.*

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.

• Pipe Fittings

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.*

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.*
