ISO7005-1 Certified Stainless Steel Backing Flange for Durable Connections

Product Description

ISO7005-1 Certified Stainless Steel Backing Flange for Durable Connections
ISO 7005 (which AS4331 is a reproduction of) also includes European DIN flanges PN6/10/16/25/40 which were previously DIN 2501-1 and BS4504. These flanges are the same as EN1092 but EN1092 also includes higher rated DIN based flanges. Consequently in Australia most users simply just reference to original ASME B16.5 standards as this is already in use in Australia for the Oil, Gas and Mining industries and in fact in pressures above table E it has been the predominant standard in use for the last 30 years. However, piping engineers must refer to the new AS standard AS4331 for interpretations and specification requirements. Note in the case of AS4331.1/ISO 7005-1 ANSI equivalents they are not absolutely identical to ANSI but "deemed to comply and are designed to be interchangeable".
Piping Class Ratings based on ASME B16.5 and corresponding PN rating:

Flange Class	150	300	400	600	900	1500	2500
Flange Pressure Nominal, PN	20	50	68	100	150	250	420

AS/NZS 4331 is identical with and has been reproduced from ISO 7005.
