A permanent seal is formed between metals! With elastic load applied, the durability of the connection is improved.
Introducing the technology of "Elastic Strain Preload (ESP)." During installation, the axial movement of the LOKRING driver on the joint body compresses the body against the pipe surface, initially elastically and then plastically compressing the pipe wall. As resistance to the compressive force on the pipe wall occurs, significant compressive loads develop at the contact area between the narrow sealing section inside the joint body and the pipe surface. 【Features】 - The pipe wall is initially compressed elastically and then plastically. - Significant compressive loads occur at the contact area between the narrow sealing section and the pipe surface. - Plastic deformation occurs on the pipe surface beneath multiple sealing sections. - A permanent seal of metal is formed between the pipe and the joint body along a 360° circumference. - The durability of the connection is enhanced. *For more details, please refer to the PDF document or feel free to contact us.

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.
