The purified water(PW) and injection water (WFI) storage tanks produced are divided into two types: vertical and horizontal. The injection water storage tank is designed and manufactured completely in accordance with pressure vessel standards. Both the interlayer and the tank can withstand steam heating of 0.3MPa and pure steam disinfection and sterilization. Pure water storage tanks are divided into two structural forms: single-layer and insulation layer. Both tanks can withstand the disinfection and sterilization conditions of pasteurization and superheated water processes.
