For those struggling with piping welding construction, here is a solution introduction.

Solve issues such as "technology inheritance," "difficulty in securing veteran engineers," and "fire risk"! Enables anyone to easily and quickly carry out construction, improving safety.

The "LOKRING fitting" is a joint that can be installed without the use of fire, eliminating any costs associated with welding. In general assembly on-site, the installation time can be significantly reduced compared to pipe welding, allowing for substantial cost savings in total expenses, including labor costs. For those inquiring, we will introduce it with videos as well. Please feel free to contact us first. 【Benefits of Introduction】 ■ No use of fire: No need for protective measures, eliminating the risk of fire or explosion ■ Installation time is about 1/10 of welding: Shortened 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 equipment, facilities, or procedures required for welding ■ No need for piping purging or cleaning ■ U-shaped dedicated tool: Allows for piping installation even in tight spaces *For more details, please download the PDF or contact us.

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.*

Utilized in major oil refineries, chemical plants, and (thermal/nuclear) power plants! Construction time is less than 1/10, allowing for shortened construction periods and cost reductions.

Generally, pipe welding in a plant requires welding permit applications, draining of piping, flushing and drying, installation of leak detectors, securing and scheduling of welders, and other tasks that can be 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 can provide case photos and videos for your reference.

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.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
