Australian Standard AS 4087 PN 21 Blind pipe flanges are used to seal the end of a piping system or pressure vessel openings to prevent flow. Australian Standard Blind flanges are mainly used for pressure testing the flow of liquid or gas through a pipe or vessel. These Australian Standard AS 4087 PN 21 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 Australian Blind Flanges in India. We offer these Australian Standard AS 4087 PN 21 flanges in ASME/ANSI/DIN standards.
