This is similar to a slip-on Flange in outline, but the bore is counter- bored to accept the pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Flange is attached to the pipe by a fillet weld around the hub of the Flange. An optional internal weld may be applied in high stress applications. Its biggest use is in high-pressure systems such as hydraulic and steam lines.
