E-Piping Company Profile

By using the non-flammable, welding-equivalent mechanical joint 'LOKRING joint', all issues related to welding construction of piping can be resolved!

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. You can view actual on-site installation footage at the following URL: https://youtu.be/OmKg2Z5Fc7o Please feel free to contact us if you have any inquiries.

Method for installing a new welded end valve to piping using Lokring fittings without the use of open flames.

  • PRODUCT

When installing new valves or equipment in the middle of piping, do you have situations where you want to use welding but cannot use 'open flames' or prefer not to? The 'Lokring fittings', which can be installed easily and quickly without using open flames, solve that problem. Since 2012, Lokring fittings have been widely used in major domestic oil refineries, chemical plants, and power plants, so you can adopt them with confidence without the need for verification. For specific details, please feel free to contact our representative.
