PT-Flonex is a PTFE expansion joint reinforced by steel rings. Working temperatures are 70C to 200C. Maximum working pressures shall vary by number of bellows, sizes, and operating temperatures. PT-Flonex is available in 2, 3, and 5 bellows in 25mm to 300mm diameters. PT-Flonex has superior chemical resistance to most chemicals, so suitable for various acids, alkaline, and solvents. PTFE contains no carbon element, no electrolysis shall be generated. With this property, it is especially recommended for use with portable water and demineralized water. PT- Flonex is widely used in chemical processing industries, paper mills, and water treatment plant.
