[National Coverage] A new technology for crack repair without welding: LNS method. Unlike conventional welding repairs, it does not apply heat that damages the base material of the equipment.
Cracks have occurred in your company's important equipment. "Is it okay to weld? I don't want to weld... I'm anxious." "First, let's try grinding the crack! ... No good." "If it's a stop hole... No good." After consideration, welding is implemented... Again, it has broken! Welding is the only way to connect it! Just need it to last for a while! However, have you ever had an experience where the results were not as expected? With Locknstitch (LNS method), we can meet your expectations! There are things that can only be done with mechanical joining that does not use heat. It is compatible with all metals. Unlike conventional welding repairs, it does not add heat that damages the base material of the equipment. By not adding that heat, secondary cracks do not occur, and heat treatment and machining are also unnecessary. As a result, repairs can be completed in a short period, leading to extended equipment life with precision, durability, and low cost.

basic information
<Merits> ■Repair Time Repairs can be completed quickly using air-operated tools that do not require complex methods such as preheating. ■Ease of Installation The head of the screw (PIN) has a groove cut into the top, allowing it to be removed with a consistent torque. The straight shape of the main body enables uniform quality work regardless of the installer. ■Clean Finish LNS pins have the shoulder of the screw inserted inside the surface, preventing exposure during installation. This allows for a clean surface finish after installation due to metal-to-metal contact. ■Maintaining Airtightness LNS pins are installed evenly without uneven stress during installation, allowing for airtight maintenance without the need for epoxy or adhesives from other similar products, ensuring high-pressure airtightness. ■Holding Power LNS pins and locks are installed at all crack locations, providing strong holding power. ■Wide Range of Applications LNS products can be applied in various situations and conditions due to the diverse sizes of screws and locks, making them suitable for corners and rounded corners, among other areas. ■On-Site Work In most cases, repairs can be performed on-site.

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.
