Developed cross-linked acrylic coating support brackets with superior heat resistance temperature of 90°C (momentarily 95°C) compared to soft PVC (polyvinyl chloride) coated support brackets.
Traditionally, the heat resistance temperature of commonly used soft PVC-coated U-bolts is up to 60°C. This is because the heat resistance temperature of soft PVC itself is considered to be around 60°C. However, with recent changes in hot water systems (the spread of eco-cute and cogeneration systems), fluid temperatures have been increasing. Additionally, stainless steel thin-walled pipes (Morko pipes, SU pipes) are used in the piping, so support brackets must use products with insulated coatings to prevent electrolysis. Therefore, our company has developed a cross-linked AC-coated U-bolt that can withstand high temperatures. The heat resistance temperature of this product is 90°C at room temperature and 95°C for short periods, making it suitable for piping with hot water.
Non-welding metal crack repair! We will repair cracks without any thermal impact. This is a collection of repair achievements related to press equipment.
The "MS Method (Mechanical Stitch)" is a groundbreaking repair technique (Mechanical Stitch Method) that addresses metal cracks using mechanical methods. Since no heat is applied at all, there is no "thermal distortion." Residual stress in other areas does not occur, preventing secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In general welding repair methods, the base material around the crack changes 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 with jigs, etc. → Accumulation of know-how, experience, and achievements ■ Completion of construction in a short period → No significant reduction in equipment operating rates ■ Advantages in safety and environmental aspects → No use of fire, so there is no impact on the operating rates of other equipment or the environment For more details, please contact us.

Why doesn't HEICO-LOCK® loosen?
Reliable, safe, and easy-to-use HEICO-LOCK(R) locking device An explanation of the principles supporting this locking device. 1. Hardness difference: H (HEICO) > H (material) The surface hardness of the washer is harder than that of the general fastening material and nut/bolt, and it firmly spikes into the surfaces of the fastening material and bolt/nut. 2. Friction difference: μ (a) > μ (i) Friction coefficient of the wedge-shaped cam surface on the inside of the washer: μ (i) Friction coefficient of the radial tooth surface on the outside of the washer: μ (a) 3. Angle difference: α > β Angle of the cam surface on the inside of HEICO-LOCK(R): α Lead angle of the screw: β 4. Axial force (preload) difference: F (dyn) > F (stat) Dynamic axial force (dyn) occurring in an environment where a load in the loosening direction is present Static axial force (stat) during tightening The locking effect of the HEICO-LOCK(R) series has been demonstrated through vibration tests in accordance with international standards. - German Industrial Standards (DIN 65151, DIN 25201-4) - U.S. Aerospace Standards (NASM 1312-7)
