USUI CO., LTD. List of Products and Services

The high-corrugated tube is a special electric-welded steel pipe formed by continuously welding the ends of coils that have been pre-treated with one-sided plating. It boasts excellent mechanical properties and pressure resistance, and is highly reliable for bending processes and end processing, making it suitable for various applications such as automotive fuel/oil pipes, piping for heat exchangers, and piping for hydraulic equipment. 【Features】 ○ Special electric-welded steel pipe formed by continuously welding the ends of coils that have been pre-treated with one-sided plating ○ Excellent mechanical properties and pressure resistance ○ High reliability for bending processes and end processing For more details, please contact us or download the catalog.

Double-wound steel pipes are pressure-resistant piping steel pipes obtained by continuously and doubly winding steel strips that have been pre-treated with copper plating on both sides, and then brazing in a special furnace. In addition to pressure resistance, they also have high vibration fatigue strength, and excel in solderability, brazability, bendability, and end processing. As a pressure-resistant piping material that combines high reliability and workability, they are applied in various uses such as automotive brake tubes and power steering tubes. 【Features】 ○ High pressure resistance and vibration fatigue strength ○ Excellent solderability, brazability, bendability, and end processing ○ A pressure-resistant piping material that combines high reliability and workability For more details, please contact us or download the catalog.
