What does ASME B16.36 cover?
Covers orifice flanges — weld neck, slip-on and threaded flanges with pressure tapings for flow measurement across an orifice plate.
Does ASME B16.36 specify the material?
No. ASME B16.36 sets dimensions; the material comes from a separate specification such as ASTM A182, A105 or B564 for flanges, or A403 and B366 for fittings. A complete order names both.
Do you supply certificates to this standard?
Yes. Material is supplied with mill test certificates to EN 10204 3.1 showing the standard, grade and heat number; 3.2 with third-party inspection on request.
