Have you ever experienced trouble with a valve leaking at the seat? We will solve that problem!
When repairing aging pipes, it is common to close the upstream valve. However, have you ever experienced a situation where the valve has a seat leak just when you need to do this? Especially in welding cases, if there is a fluid leak, construction cannot proceed. The 'Lokring fitting', which can be installed easily and quickly without using fire, solves that problem. I believe you will find it easier to understand by watching the video at the (related link). Since Lokring fittings have a proven track record in major domestic oil refineries, chemical plants, and power plants since 2012, you can adopt them with confidence.

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.
