In recent times, with the shortage of manpower in welding and piping construction being a concern, it has become easier to secure personnel since special skills are not required, and we have received many positive responses.
The "LOKRING fitting" does not require welding technology for installation, and with a short training session, anyone can perform the installation, making it easy to secure workers. As a result, skilled welders are freed from small-diameter pipe welding and can focus on large-diameter pipes and critical welding tasks. Additionally, the work time can be reduced to one-tenth compared to welding, ultimately helping to address labor shortages. This is expected to be beneficial for companies facing difficulties in securing technicians due to the decrease in experienced engineers with extensive knowledge and experience in welding and piping installation. For inquiries, we can provide case photos and videos as well. Please feel free to contact us. 【Benefits of Introduction】 ■ No equipment, facilities, or procedures required for welding ■ Installation time is about 1/10 of welding: reduced construction period ■ Can also be used for repairs of existing corroded piping ■ Simple and quick installation: minimizes equipment downtime ■ Permanent connection: no maintenance or repairs needed after installation ■ No need for piping purging or cleaning ■ U-shaped dedicated tool: allows piping installation in narrow spaces ■ No use of fire: no need for protective measures, eliminating the risk of fire or explosion

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.
