Table D Flanges
What are Table D Flanges?
Table D Flanges are a type of pipe flange standardized under the Australian Standard AS 2129, designed for low-pressure applications in water, gas, and air systems. Manufactured typically from mild steel or stainless steel, these flanges offer a simple and effective method for joining pipes and valves. Their robust design ensures reliable sealing and easy assembly, especially in non-critical environments.
Asiad Steel Industries is a trusted supplier of Table D Flanges, offering precision-manufactured solutions that comply with international quality and dimensional tolerances.
