Temperature Rating :
Pressure Ratings are calculated in
accordance with ANSI code of pressure
piping ANSI B-31, for Stainless Steel Fittings.
All working pressures are at 4:1 safety factor.
Pressure Rating :
Precision cleaning is done by Ultra Sonic cleaning process with D.I. water after the passivation.
Cleaning :
Each finished component is double bagged in a clean room to ensure cleanliness and protect it from
