Applications of Ansi B16.5 Lap Joint Flanges
Piping Systems with Rotational Freedom:
They are used in piping systems where rotational freedom and easy alignment are required during installation,such as in offshore platforms,shipbuilding,and large-scaleindustrial facilities.
High-Temperature Applications:
LJ Flanges are employed in high-temperature piping systems where thermal expansion and contraction may occur,allowing for flexibility and stress reliefat the joint.
Temporary Connections:
They are used as temporary connections or test flanges in piping systems for bypass piping,pressure testing,
corrosive Environments:
Lap Joint Flanges are suitable for corrosive environments where the flange material may need to be different from the pipe material, as the stub end can be made of a different material than the flange.
