basic information
**Advantages of LNS Repair** *Comparison of LNS technology with welding and existing similar products* ○ Repair Time Repairs can be completed quickly using air-operated tools that do not require complex methods such as preheating. ○ Ease of Installation The upper part of the PIN is grooved to allow the head of the screw (PIN) to be removed with a consistent torque, enabling uniform quality work regardless of the installer, thanks to the straight shape of the main body. ○ Surface Treatment LNS pins have the shoulder of the screw inserted inside the surface, preventing exposure during installation, allowing for a clean surface treatment after installation due to metal-to-metal contact. ○ Air Tightness Maintenance LNS pins are installed evenly without uneven stress during installation, maintaining air tightness without the need for epoxy or adhesives used in other similar products, enabling high-pressure air tightness. ○ Pulling Force LNS pins and locks are installed at all crack locations, providing strong pulling force. ○ Versatile Application LNS products can be applied in various ways depending on the repair situation and conditions, especially applicable in corners and rounded corners. ○ On-Site Work In most cases, repairs can be performed on-site. ● For more details, please download the catalog or contact us.

Company information
<We provide nationwide support> LNS JAPAN Co., Ltd. is an engineering company that performs maintenance and repairs on cracks and damages in equipment and metal structures across various industries (such as petroleum, chemicals, power generation facilities, ships, heavy equipment, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a tough situation regarding new capital investment due to the global economic downturn. In Japan's industries, welding technology, which is widely used for metal repairs, has recently led to significant damage to many pieces of equipment and critical assets due to a shortage of skilled craftsmen and inexperienced welding repairs, with many cases worsening. Our company is the only certified company in Japan and is committed to continuous technological development in collaboration with our parent company, LOCK-N-STITCH INC, which continues to leap and grow as a global enterprise. We promise to ensure that our repairs do not cause deformation or secondary cracks due to heat, which have been issues with traditional welding repairs, while also shortening construction periods and reducing costs, thereby extending the life of equipment and ensuring high quality and prompt maintenance. For repairs where fire is not desired or where time is limited, please contact LNS JAPAN.
