The PFP and PSP series flanges were created to adapt to standard pipes with sizes ranging between DN10 and DN150, and guarantee tightness coupling also in case of frequent disassembly/reassembly. Each flange has a Rp1/8” (UNI EN 10226) threaded hole in which it is possible to mount a pressure tap allowing for quick and easy pressure check. The use of flanges makes the installation of auxiliary equipment easier and guarantees quick maintenance and replacement, without needing to make modifications on the pipeline.
