Non-Lined

Flange Specifications

  • 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 normally in Grade 304 SS, or Grade 316 SS if required
  • 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

Surface Finish

  • All surface finishes are to ASME BPE-SF-O (No finish required).
  • If a specified finish on a particular surface is required, please state on the enquiry and order.

Maximum Pressure Ratings

  • ANSI 150# = 16 Bar (230 psi), 
  • ANSI 300# = 41.4 Bar (600 psi)
  • DIN PN10 = 10 Bar (145 psi),
  • DIN PN16 = 16 Bar (230 psi)
  • DIN PN40 = 40 Bar (580 psi)
