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

We have received positive feedback that, due to the ability to carry out construction in bad weather and any situation, we can prevent delays in the project and reduce the waiting time for workers.

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.*

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 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 seismic sensor device "HK-2" detects strong tremors equivalent to a seismic intensity of 5 or higher, transmits a signal to the control room, and emergency stops the facility equipment. 【Installation Location】 Automotive parts factory 【Challenges】 Due to the maintenance and replacement of the factory equipment control devices, we considered updating the existing seismic sensors as well, but since production had already ended, we were looking for alternatives. 【Effects After Installation】 The HK-2 has the function to emergency stop equipment during an earthquake, and since its functionality is the same as the existing device, it was introduced as a replacement. Its compact size also allowed it to fit within the existing control panel being used. ★See more examples of the seismic sensor device "HK-2" https://www.hotron.co.jp/recommend/HK-2_lp.html#anchor_a04 ◎For more details, please download the materials or contact us.

An article about our resident business has been published in the Daily Timber News (Housing Edition). In light of the enforcement of last year's amendments to the Energy Conservation Law for Buildings and the Building Standards Act, as well as the heightened interest in earthquake countermeasures for the Nankai Trough, the "wallstat verification," which is effective for visualizing seismic performance in line with current conditions, is introduced. Our company supports housing businesses nationwide through our construction business support service "Ken-Sapo," including wallstat, so we hope you will take a look.
