Large plant and long-distance piping: PTFE flexible pipe for large displacements.
100mm and 200mm eccentric compatibility. PTFE flexible material capable of absorbing large displacements. It combines flexibility, pressure resistance, and cleanliness, making it suitable for various fluids.
The 【RY21】 series is a flexible joint made of full-contact PTFE (fluororesin) designed for flange piping. 【RY21M】 for 100mm eccentricity 【RY21L】 for 200mm eccentricity The exterior uses SUS blades to ensure pressure resistance, and many technologies have been integrated into the tube structure and components used. It is compatible with various fluids such as ultra-pure water, pure chemicals, chemical wastewater, and high-temperature water. 【Features】 ■ Uses Teflon (PTFE) convoluted hose ■ Chemical resistance + flexibility + durability ■ Calculated pressure resistance performance with SUS blades ■ Flare processing that consolidates high technical capabilities ■ Maximum effective length secured between each face ■ Conductive tubes are also available (RY41) 【Main Usage Locations】 ■ Long-distance piping, connecting piping, culverts, and building intake piping. ■ Earthquake resistance, earthquake measures, seismic countermeasures, BCP countermeasure construction 【Points】 ■ Cleanliness The contact material is made entirely of PTFE (Teflon, fluororesin), minimizing the leaching of impurities to the utmost limit. ■ Flexibility High flexibility is achieved through spiral PTFE and specially developed component structures.
