[Example] I want to reduce welding preparation time, shorten the construction period, and keep costs down.
Utilized in major oil refineries, chemical plants, and (thermal/nuclear) power plants! Construction time is less than 1/10, allowing for shortened construction periods and cost reductions.
Generally, pipe welding within a plant requires welding permit applications, draining of pipes, flushing and drying, installation of leak detectors, securing and scheduling of welding personnel, and other tasks that are time-consuming and costly. Additionally, the installation and dismantling of scaffolding, installation of ventilation equipment, fireproofing, and installation of fire extinguishing equipment are necessary, which can make rapid repairs difficult. The "LOKRING fitting" does not use fire, requires no preparation or procedures before and after installation, and can be easily and quickly installed by anyone after just a few hours of training, allowing for significant reductions in construction time and overall installation costs. For inquiries, we will introduce case photos and videos. Please feel free to contact us. 【Benefits of Introduction】 ■ No use of fire: No need for fireproofing, eliminating the risk of fire and explosion ■ Installation time is about 1/10 of welding: Shortened construction period ■ Usable for repairs of existing corroded pipes ■ Simple and quick installation: Minimizes equipment downtime ■ Permanent connection: No maintenance or repairs needed after installation ■ No equipment, facilities, or procedures required for welding ■ No need for purging or cleaning of pipes ■ U-shaped dedicated tool: Allows for pipe installation in narrow spaces

Company information
We handle the 'LOKRING fittings', which allow for 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 open flames, they not only enhance safety but also significantly reduce overall construction costs through shorter 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.
