In the pharmaceutical plants , some technics processes refer to storage and preparation . Such as , storage of purified water comes to storage tank , WFI comes to WFI storage tank etc.  
 Learning about this system , Gzcsci  supplies design ,manufacture , instillation , measure and validation supporting sevice for customers . 
 To reach special requirements of biological engineering equipment , technics vessel must have good structure complying with requirements of pharmaceutical and sanitation . 
Machining as the pressure vessel quality assurance system . 
  Chemical stability of material ---undissolved , innoxious , stainless steel 304, 316L.
  Surface treatment ---- mechanical and electro-polishing for the contact surface with media  onnection mode ---- argon protection welding.
Structure ---- aseptic and sanitation.  
Seal ---- a good seal system , should regarde to the seal level , working pressure , working temperature , anti-cavitation , sterilization ,clean , passivation . 
Slope : solution drain by itself gravity . 
Diameter and length ratio of nozzle and dead leg of pipeline ----if the length and diameter ratio is big , matters tend to remain , microorganisms are prone to grow up .

Easy connection --- CIP and SIP connection easily .
