We would like to introduce our "Stainless Steel Flexible Tubes." These tubes are made by forming thin-walled electric welded pipes (0.2mm to 0.6mm) into a continuous pleated shape, and then braiding stainless steel wire (blade) around the outside. Finally, fittings are attached to both ends to complete the product. In addition to flexibility and bendability, they also serve to absorb micro-vibrations. 【Features】 ■ Standard material: SUS304 ■ SUS316L is also available for applications requiring higher heat resistance and corrosion resistance. ■ Heat resistance temperature: - SUS304: -194℃ to 400℃ - SUS316L: -194℃ to 600℃ ■ Pressure resistance: 1.0MPa ■ It is also possible to double the outer blades or use high-pressure fittings to achieve 2.0MPa. *For more details, please refer to the related links or feel free to contact us.
