Real Data You Can See
This thing works from -70℃ to 230℃. It handles pressures from PN6 to PN16. Each PTFE lined expansion joint gets a water test at 1.5 times the design pressure. We also do an air tightness test. It takes in axial, lateral, angular, and combined moves. The inside wall is very smooth. It does not stick, build up, or let anything through. It has no metal touching the media. So there is no galvanic corrosion or metal ion pollution. Our factory is 10,000 square meters with 50 workers. We give a 24-month warranty.
