API 605 Class 300 Blind flanges are used to seal the end of a piping system or pressure vessel openings to prevent flow.API 605 Class 300 Blind flanges are mainly used for pressure testing the flow of liquid or gas through a pipe or vessel. These API 605 flanges also allow easy access to the pipe in the event that work must be done inside the line. Tesco Steel & Engineering manufacture a wide range of high quality API Blind Flanges in India. We offer these API 605 Class 300 flanges in ASME/ANSI/DIN standards.
