LOKRING fitting

In coastal areas with many chemical plants and power stations affected by salt damage, we have numerous achievements as an alternative to flange joints! Technical documents using salt spray testing are also available!

In chemical plants and power stations, many "flanged joints" are used outdoors. Flanged joints are essential for connections with valves and equipment. However, there are many pipes carrying flammable fluids in the surrounding area, and hot work such as welding poses risks, necessitating fire protection measures. Additionally, there is a possibility of rainwater entering the gasket area, leading to corrosion and causing fluid leaks, which can be time-consuming and labor-intensive to inspect. This issue is particularly exacerbated in petrochemical plants and power stations located along the coast, where salt damage further complicates the problem. The 'Lokring joint' provided by E-Piping features a sealing structure (inboard seal and outboard seal) that isolates the main seal from external environments and internal fluids, thereby reducing the likelihood of leaks. (Refer to the PDF for more details) **Features of Lokring Joints** - Reduces the possibility of leaks! - Can be installed easily and quickly without using fire! - Contributes to improved safety, reduced labor, and lower overall installation costs! - Suitable for installation in hazardous areas with risks of ignition or explosion, as well as underwater. *For more details, please download the PDF or contact us directly.*

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. 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.
