ASME B16.5 Socket-Weld Flanges has a master groove mounted on the pipe. The fillet weld is carried out outside the pipe. The counterbore is larger than the pipe diameter to match, so the pipe should be inserted flange and flange slip. The socket welding flange is similar to a slip-on flange, except for a hole and a hole size.
ASME/ANSI B16.5 Class 150 Socket-Weld Flanges is a primary pressure level in this range of products. Other higher pressure grade products of ASME B16.5 Socket-Weld Flanges, the optional internal weld can be applied to high stress applications.
