Three types of pipes are used for the evaluation! Burst tests and bending fatigue tests are conducted.
Lokring Corporation has been asked to evaluate the performance of the joint line of the MAS-3000 product installed on Japanese Industrial Standards (JIS) carbon steel pipes. Therefore, burst tests and bending fatigue tests were conducted on Lokring MAS-3000 carbon steel products installed on JIS G 3454 STPG 370, G 3455 STS 370, and G 3456 STPT 370 carbon steel pipes.

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.
