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

environmental contamination.
