Information
Lap Joint Flange 4'' Class 150 316L ASME B16.5 is designed for use with stub ends (lap joint ends) in piping systems requiring frequent dismantling, inspection, or cleaning. The loose flange rotates freely around the pipe, making bolt hole alignment quick and easy during installation.

- Easy alignment of bolt holes due to free rotation
- The flange is not in direct contact with the process medium
- Can be reused when replacing the stub end or piping
- Ideal for systems requiring frequent maintenance
