📘 Standard Overview: Australian Water Standard AS 4087
The AS 4087 Standard specifies metallic flanges for the Australian water supply industry. Unlike general-purpose standards, AS 4087 introduces unique pressure ratings (PN21 and PN35) alongside the common PN16, which are optimized for water and wastewater pipelines and equipment. This standard ensures dimensional interchangeability for various water applications and is often specified by municipal authorities throughout Australia and New Zealand.
Standard Flange Types
- Slip-On Flanges: For pipework that allows for easy alignment before welding (most common).
- Blind Flanges: For sealing the ends of pipes, valves, or equipment openings. (Blind Flange Category)
- Also covers Mechanical Joints and Flange Adapters.
Size & Material Focus
- Nominal Size (DN): DN50 up to DN1200 (2 inches to 48 inches).
- Carbon Steel: Typically to AS 2074 Gr. 250 / ASTM A105 equivalent.
- Stainless Steel: Grades 304L / 316L for corrosive environments.
- Ductile Iron: Used widely for water industry valves and fittings.
