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.

Generally, pipe welding within a plant requires welding permit applications, draining of pipes, flushing and drying, installation of leak detectors, securing and scheduling of welding personnel, and other tasks that are time-consuming and costly. Additionally, the installation and dismantling of scaffolding, installation of ventilation equipment, fireproofing, and installation of fire extinguishing equipment are necessary, which can make rapid repairs difficult. The "LOKRING fitting" does not use fire, requires no preparation or procedures before and after installation, and can be easily and quickly installed by anyone after just a few hours of training, allowing for significant reductions in construction time and overall installation costs. For inquiries, we will introduce case photos and videos. Please feel free to contact us. 【Benefits of Introduction】 ■ No use of fire: No need for fireproofing, eliminating the risk of fire and explosion ■ Installation time is about 1/10 of welding: Shortened construction period ■ Usable for repairs of existing corroded pipes ■ Simple and quick installation: Minimizes equipment downtime ■ Permanent connection: No maintenance or repairs needed after installation ■ No equipment, facilities, or procedures required for welding ■ No need for purging or cleaning of pipes ■ U-shaped dedicated tool: Allows for pipe installation in narrow spaces

The "LOKRING joint" is a fitting that can be installed in any weather and under any circumstances, preventing construction delays and reducing worker waiting time, which has received positive feedback. Since it is installed using a dedicated hydraulic tool without the use of open flames, it is not affected by rain or wind. There are even cases of it being used underwater. When piping is adjacent to walls, ceilings, or floors, the dedicated tool for the "LOKRING joint" is U-shaped, allowing easy access from any direction without moving the pipes, even in tight spaces. This is particularly effective when it is in contact with the main pipe, such as in steam tracing piping. Installation can be done even when fluid is flowing. For example, when repairing downstream piping, the upstream stop valve is closed, but sometimes debris on the valve seat can cause a seat leak, resulting in a small amount of fluid flow. The "LOKRING joint" can be installed even if there is some leakage from the joint or piping, as long as it can be secured to the piping. *For more details, please download the PDF or contact us.*

The "LOKRING fitting" does not require welding technology for installation, and with a short training session, anyone can perform the installation, making it easy to secure workers. As a result, skilled welders are freed from small-diameter pipe welding and can focus on large-diameter pipes and critical welding tasks. Additionally, the work time can be reduced to one-tenth compared to welding, ultimately helping to address labor shortages. This is expected to be beneficial for companies facing difficulties in securing technicians due to the decrease in experienced engineers with extensive knowledge and experience in welding and piping installation. For inquiries, we can provide case photos and videos as well. Please feel free to contact us. 【Benefits of Introduction】 ■ No equipment, facilities, or procedures required for welding ■ Installation time is about 1/10 of welding: reduced construction period ■ Can also be used for repairs of existing corroded piping ■ Simple and quick installation: minimizes equipment downtime ■ Permanent connection: no maintenance or repairs needed after installation ■ No need for piping purging or cleaning ■ U-shaped dedicated tool: allows piping installation in narrow spaces ■ No use of fire: no need for protective measures, eliminating the risk of fire or explosion

We will introduce the installation procedure for the 'MAS-3000 Series' that we handle. First, cut the pipe at a right angle and use 120-grit sandpaper to polish the sealing surface in a circular manner, cleaning the surface to remove any scratches. Next, use a Multi-Purpose Gauge (MPG) to confirm that the outer diameter of the pipe is the appropriate size and mark the pipe. If the surface condition of the pipe is poor, apply a thin layer of PST sealant (liquid TFE) as an aid for sealing. Then, select the necessary LOKRING tools for installation, inspect the tools to ensure they operate correctly, set the fitting at the location marked "INSTALL," and securely install it while operating the tool. Finally, visually confirm that the installation has been performed correctly. *For more details, please refer to the PDF materials or feel free to contact us.
