AS2129 Table J flange is a weld neck flange complying with Australian standard AS2129, designed for high-pressure and high-temperature service. It has a long tapered hub for butt-welding to pipes, effectively reducing stress and improving fatigue resistance. Our Table J flanges are widely used in oil, gas, water transmission, petrochemical and power plant pipelines.
Production Details
Each AS2129 Table J flange is manufactured under full-process quality control:
Raw material inspection with mill certificates and spectral analysis
