Expansion Joint Limit Rods

Single Metallic Expansion Joint
Limit Rods

It is sometimes desirable to limit the axial expansion or compression of the pipe expansion joint. Limit rods, shown above, provide freedom of movement over a range determined by the location of nut stops along the rods. In the event of the main anchor failure, limit rods are designed to prevent bellows over-extension while restraining the full pressure thrust of the system.
