Table E Flanges
What are Table E Flanges?
Table E Flanges are medium-pressure flanges defined under the AS 2129 standard, used extensively in waterworks, air systems, and low- to medium-pressure pipelines. Designed for applications up to 1400 kPa (Class PN20), they offer a reliable flange connection ideal for both above-ground and underground piping.
Asiad Steel Industries is a leading manufacturer and exporter of high-quality Table E Flanges designed to meet demanding performance requirements across utility, industrial, and agricultural sectors.
