Sealing surface (standard RF/FF/MFM) is machined to Ra1.6-Ra3.2 standard roughness, dimensional tolerance controlled within ±0.05mm, fitting tightly with standard gaskets to achieve absolute sealing of pipeline shutoff;
Bolt holes are evenly distributed and accurately positioned, matching high-strength bolts, ensuring uniform pre-tightening force and no loose connection after installation;
Hub and flange body are seamlessly forged, with smooth transition and no stress concentration points. |
