Lap Joint Flange FeaturesLap Joint Flange SizesLap Joint Flange Materials
Lap joint flanges fit over a pipe with a flared or stub end. This allows the flanges to swivel freely to easily align bolt holes. These are ideal for systems whose design / layout may change or are frequently disassembled. The biggest advantage of lap joint flanges is that the flanges are not welded in place however its an overall much weaker connection than other flanges styles.

Socket Weld Flange FeaturesSocket Weld Flange SizesSocket Weld Flange Materials
Socket weld flanges have an internal stop to support pipes when welding. By inserting a pipe into the socket, this stop prevents the pipe from sliding all the way through and then the flange is fillet welded to secure the connection. Socket weld flanges are similar to slip on flanges but offer a high strength connection.

Weld Neck Flange FeaturesWeld Neck Flange SizesWeld Neck Flange Materials
Weld neck flanges are welded directly to the pipe at the neck of the flange. The flange neck has a beveled end that, when connected to a pipe, creates a trough for a strong weld. This flange is desirable for high pressure applications. These flanges are also knows as Butt Weld Flanges.
