"MS Method" Metal crack repair without heat! A new method that does not generate thermal distortion.

No secondary cracking thermal distortion occurs! Cast iron crack repair! Metal crack repair!

The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitching Method) that uses mechanical methods to address cracks in metal. Since no heat is applied at all, there is no "thermal distortion." There is no residual stress in other areas, preventing secondary damage such as new cracks. Cracks in metal are one of the concerns in equipment maintenance. Conventional welding repair methods change the base material around the crack due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." 【Features】 ■ No hardening or residual stress due to heat ■ Elimination of secondary damage ■ Maintenance of stable quality 　→ Integrated system repairs using jigs, etc. 　→ Accumulation of know-how, experience, and achievements ■ Completion of construction in a short period 　→ No significant decrease in the operating rate of equipment ■ Advantages in safety and environmental aspects 　→ No use of fire, so there is no impact on the operating rate of other equipment or the environment.

basic information

The MS method for repairing metal cracks demonstrates outstanding effectiveness in terms of precision, durability, and cost compared to conventional methods. This technology physically repairs cracks using our special bolts and reinforcement plates, allowing for on-site construction, which leads to reduced delivery times and lower costs. We have experience in a wide range of fields, including cast iron cracks, marine equipment, power generation facilities, and cement equipment. Please feel free to contact us if you have any questions. 【Product Lineup】 ■ S Bolt → Ensures airtightness and crack removal → Thoughtfully designed screw structure achieves tensile strength of the base material ■ T Bolt → Prevents MS reinforcement plate from pulling out and patch repairs → Unique tapered section enhances airtightness and prevents loosening ■ MS Reinforcement Plate → Reinforces and restores the repair area → Suppresses the force that causes cracks to spread and strongly reinforces the base material ■ MS Bolt Hole Repair Insert → Female screw part for reinforcing damaged bolt holes ・ HS Type Insert: For cases where there are no cracks around the bolt hole ・ HF Type Insert: For cases where there are cracks around the bolt hole
