AS 2129 and AS 4087 are widely used Australian flange standards designed for industrial piping, water supply, and infrastructure systems. AS 2129 flanges follow a traditional table system (Table D, E, F, H), while AS 4087 adopts the PN pressure rating system, such as PN16, PN21, and PN35, which is commonly used in modern water and wastewater projects.
AS 2129 flanges are widely applied in general industrial pipelines, mining projects, and low to medium pressure systems. They provide stable sealing performance and are available in slip-on, weld neck, blind, and threaded types. On the other hand, AS 4087 flanges are mainly used in municipal water systems, pump stations, and pipeline networks where PN-rated pressure control is required.
