Flange Specification
- ANSI B16.5 (also ASME B16.5) Class 150# and 300#
- *DIN PN10/16/40 up to 2" size, PN10/16 from 2 1/2" up to 6" size
- JIS 10K
- Other Pressure Ratings and Flange Specifications are also available.
*The dimensions for flanges to the different pressure ratings are identical, so they are inter-changeable.
Maximum Pressure Ratings for Flange Fittings
- ANSI 150# = 16 Bar (230 psi), ANSI 300# = 32 Bar (460 psi)
- DIN PN10 = 10 Bar (145 psi), DIN PN16 = 16 Bar (230 psi), DIN PN40 = 40 Bar (580 psi)
End Fitting Materials
- Flanges in Grade 304 SS
- Flange Retainers in Grade 316L SS
- Ferrules, most in Grade 304 SS, some sizes in Grade 316 SS
Alternative Options for Flange Component only:
- Zinc Plated Carbon Steel
- Blue Epoxy Coated Carbon Steel
