FLANGE SPECIFICATION
- ANSI B16.5 (also ASME B16.5) Class 150# and 300#
- *DIN PN10, PN16 and PN40
- JIS 10K
- Other Pressure Ratings and Flange Specifications are also available.
*DIN PN10, PN16 and PN40 Flanges all have the same dimensions, and so are fully interchangeable.
END FITTING MATERIALS
- Flanges in Grade 304 SS
- Flange Retainers in Grade 316L SS
- Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS
PRESSURE RATINGS
- ANSI 150# = 230 psi (16 Bar), ANSI 300# = 460 psi (32 Bar).
- DN PN10 =145 psi (10 Bar), DN PN16 = 230 psi (16 Bar), DN PN40 = 580 psi (40 Bar).
