The microelectronics industry (semiconductor production, PCB production, etc.) and the life sciences industry (pharmaceuticals, bio-technology, etc.) need related piping system to transport ultra pure media (UPW, HPW, PW, WFI), highly aggressive chemicals (H2SO4, HCI, HF, NaOH, HNO3, etc.), aggressive exhaust air and contaminated process air. In this demanding field of application, stringent requirements are placed on purity, chemical resistance and safety.
