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 compressing the pipe wall elastically, followed by plastic compression. As resistance to the compressive force on the pipe wall occurs, significant compressive loads develop at the contact points between the narrow sealing area within the joint body and the pipe surface. 【Features】 - The pipe wall is initially compressed elastically, followed by plastic compression. - Significant compressive loads occur at the contact points between the narrow sealing area and the pipe surface. - Plastic deformation occurs on the pipe surface beneath multiple sealing areas. - A permanent seal of metal is formed between the pipe and the joint body along a 360° circumference. - Durability of the connection is increased. *For more details, please refer to the PDF document or feel free to contact us.

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.
