Installation Guidelines for Carbon Steel LOKRING Fittings

Installation Guidelines for Carbon Steel LOKRING Fittings

Set the fitting at the INSTALL mark! Here are the installation instructions for the carbon steel LOKRING fitting.

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 ensure that the outer diameter of the pipe is the correct 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 done correctly. *For more details, please refer to the PDF materials or feel free to contact us.

[Example] I want to improve the effects of weather, the welder's skill level, and the welding space, among others.

Due to the ability to carry out construction in any weather conditions, we have received positive feedback that it prevents delays in construction and reduces the waiting time for workers.

The "LOKRING fitting" is a fitting that can be installed in any weather and under any circumstances, preventing construction delays and reducing workers' 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 where it has been used underwater. When piping is adjacent to walls, ceilings, or floors, the dedicated tool for the "LOKRING fitting" is U-shaped, allowing easy access from any direction without moving the pipes, even in tight spaces. This is particularly effective when dealing with steam trace piping that is in contact with the main pipe. Installation can be performed 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 fitting" can be installed even if there is some leakage from the fitting or piping, as long as it can be secured to the piping. *For more details, please download the PDF or contact us.*

[Case Study] For those struggling to secure personnel for welding and piping construction.

[Case Study] For those struggling to secure personnel for welding and piping construction.

In recent times, with the shortage of manpower in welding and piping construction being a concern, it has become easier to secure personnel since special skills are not required, and we have received many positive responses.

The "LOKRING fitting" does not require welding technology for installation, and anyone can perform the installation after receiving a short training session, making it easier to secure workers. As a result, welders can be freed from welding small-diameter pipes and can focus on larger 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: shortened construction period ■ Can also be used for repairing existing corroded pipes ■ Simple and quick installation: minimizes equipment downtime ■ Permanent connection: no maintenance or repairs needed after installation ■ No need for pipe 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

[Case] I want to improve the decline in quality caused by difficulties in inheriting technology.

Anyone can easily and quickly perform reliable construction equivalent to welding, contributing to quality improvement and maintenance.

The "LOKRING fitting" is a joint that allows anyone to easily and quickly perform installations at a level equivalent to welding. Therefore, it can solve the problem of "the lack of successors in an era where the inheritance of technology is not progressing as hoped, leading to a decline in technical skills (quality)." Since it does not require heating work, it is also expected to reduce the accident rate related to OSHA. For those who inquire, we will introduce it with videos as well. Please feel free to contact us first. 【Benefits of Implementation】 ■ No equipment, facilities, or procedures required for welding ■ Installation time is about 1/10 of welding: shortened construction period ■ Can also be used for repairing existing corroded pipes ■ Simple and quick installation: minimizes equipment downtime ■ Permanent connection: no maintenance or repairs needed after installation ■ No need for pipe purging or cleaning ■ U-shaped dedicated tool: allows pipe installation even in narrow spaces ■ No use of open flames: no need for protective measures, eliminating the risk of fire or explosion *For more details, please download the PDF or contact us.

Welding uses fire, so safety is a concern. We provide peace of mind and address such worries.

The "LOKRING fitting" is a fitting that reduces fire risk and enhances safety because it does not use open flames. Since there is no heating work involved, it leads to a decrease in the accident rate related to the Occupational Safety and Health Administration (OSHA). We have also received positive feedback regarding the fact that there are no costs associated with welding. For those who inquire, we will introduce it with videos as well.

Technology of elastic strain preload

Technology of elastic strain preload

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.
