Not welding! A new method for repairing metal cracks! Prevents damage and recurrence of cracks without adding heat - permanent solution for metal fractures.
Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

basic information
The MS method for repairing metal cracks demonstrates outstanding effectiveness in terms of precision, durability, and cost compared to conventional methods. It is a technique that physically repairs cracks using our special bolts and reinforcement plates. Since it can be implemented on-site, it allows for reduced lead times and cost savings. We have extensive experience in various 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 removes cracks → 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 thread 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

Detailed information
-
Mechanical Stitching Method (Crack Repair) The mechanical stitching method is an innovative crack repair technique that does not apply heat, preventing hardening and residual stress, and also preventing secondary damage.
-
MS Insert Kit (Bolt Hole Repair) The MS Insert is a female thread part used to repair damaged bolt holes. Due to its specially designed external thread structure, it is difficult to pull out and does not put stress on the base material.
