The anchor flange is a crucial fixed component used in pipeline systems, primarily serving as a rigid anchoring point to prevent displacement caused by temperature variations, pressure fluctuations, or external loads such as earthquakes and soil movement. It is typically welded onto the pipeline and connected to a concrete foundation or other fixed structures via bolts, ensuring the pipeline’s stability at a designated position while distributing stress to protect the pipeline system from damage.

Available material options include carbon steels such as 10# and 20#, alloy steels like 16MnR and 12Cr1MoV, as well as stainless steels including ASTM A403 and 1Cr18Ni9Ti. Pressure ratings range from 150LB, 300LB, 400LB, 600LB, 900LB, 1500LB to 2500LB, with standard sizes from NPS 1/2 to NPS 24.

As the "anchor point" of pipeline systems, the anchor flange plays an irreplaceable role in ensuring pipeline safety through rigid fixation and stress distribution. Its high-strength structure, corrosion resistance, and broad applicability make it a key component in industries such as petroleum, chemical processing, and municipal engineering.
