Fire hazard evaluation item No. 20! Effective for piping where axis shapes such as steam, hot water, and oil delivery pipes cannot be used.
We handle "Universal Bellows Type Expansion Joint" at our company. The universal type restrains internal pressure thrust by connecting two bellows with tie rod bolts, allowing it to absorb lateral (perpendicular to the axis) displacement. The pressure ratings are up to 1.0 MPa for certified products and between 0.2 MPa and 2.0 MPa for general products. It is effective for countermeasures against uneven settlement of tanks, earthquake measures, and in piping where axial alignment cannot be used, such as steam, hot water, and oil transfer pipes. 【Features】 ■ Certified product No. 20 for fire safety ■ By connecting two bellows with tie rod bolts, it restrains internal pressure thrust and absorbs lateral (perpendicular to the axis) displacement. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Technoflex's flagship product, the flexible hose, is widely used in various applications such as piping for city gas and LP gas, water supply and drainage pipes in water purification plants and dams, as well as in general construction and fire protection piping, due to its excellent heat and pressure resistance and minimal issues arising from aging. Additionally, the bellows-type expansion joint is utilized in large-scale industrial facilities such as petrochemicals, power generation, LNG, and steelmaking, and has a significant track record of deliveries. The manufacturing bases include five domestic locations that have obtained ISO9001 certification at all sites, as well as three overseas locations in Tianjin, Shanghai, and Vietnam. We have established a system that can broadly accommodate various fields, ranging from low-cost, readily available stock items to products requiring advanced quality control for nuclear power plants.
