If your project requires large-diameter titanium flanges, ASME B16.47 Titanium Flanges are your ideal choice. Unlike ASME B16.5 Titanium Flanges, which cover sizes up to 24 inches, ASME B16.47 flanges range from 26 to 60 inches and are specifically designed for large pipelines and offshore applications.
At Baoji Zecheng Metal Materials Co., Ltd., we provide ASME B16.47 Flanges in Gr.2, Gr.5, Gr.7, and Gr.12, offering excellent strength, moderate density, and high deformability to suit your engineering needs. Our flanges are widely used in oil & gas, chemical, power, desalination, and marine industries. With ISO9001 and AS9100 certification, we ensure stable and reliable quality for every order.
