[Example] I want to improve the effects of weather, the welder's skill level, and the welding space, among others.
Due to the ability to carry out construction in any weather conditions, we have received positive feedback that it prevents delays in construction and reduces the waiting time for workers.
The "LOKRING fitting" is a fitting that can be installed in any weather and under any circumstances, preventing construction delays and reducing workers' waiting time, which has received positive feedback. Since it is installed using a dedicated hydraulic tool without the use of open flames, it is not affected by rain or wind. There are even cases where it has been used underwater. When piping is adjacent to walls, ceilings, or floors, the dedicated tool for the "LOKRING fitting" is U-shaped, allowing easy access from any direction without moving the pipes, even in tight spaces. This is particularly effective when dealing with steam trace piping that is in contact with the main pipe. Installation can be performed even when fluid is flowing. For example, when repairing downstream piping, the upstream stop valve is closed, but sometimes debris on the valve seat can cause a seat leak, resulting in a small amount of fluid flow. The "LOKRING fitting" can be installed even if there is some leakage from the fitting or piping, as long as it can be secured to the piping. *For more details, please download the PDF or contact us.*

Company information
We handle the 'LOKRING' fittings, which provide easy and reliable pipe connections with a level of reliability equivalent to welding. The 'LOKRING' fittings were developed by NASA in 1987 and are used worldwide as a mechanical joint that serves as a non-welding alternative compliant with ASME B31. Because they can be installed easily and quickly without the use of flames, they not only enhance safety but also significantly reduce total construction costs through shortened installation times and lower labor costs. Since 2012, they have been used in many petrochemical plants, thermal and nuclear power plants in Japan, making them a reliable choice.
