ANSI 150 RF Threaded Flange

Threaded flange is a flange of the inner hole machining into pipe thread, and implementation and threaded pipe connections, is a kind of welding flange.It peace or butt welding flange compared to flange, threaded flange has the characteristics of convenient installation, maintenance, can be used on some site doesn't allow the welding line.Alloy steel flange has enough strength, but not easy to welding, or bad welding performance, can also choose threaded flange.But in the pipe temperature changes or sharply temperature higher than 260 ℃ below - 45 ℃ under the condition of threaded flanges are not recommended, so as to avoid leakage.
