Restrained Mechanical Joint vs. Regular Mechanical Joint
Restrained Mechanical Joint vs. Regular Mechanical Joint
(OP)
I am new to the water world. Is the only difference between a restrained mechanical joint and a regular mechanical joint the addition of a grip ring such as a mega lug that has set screws that screw down onto the pipe. Also does a concrete kicker make a regular mechanical joint a restrained mechanical joint.
Any information would be helpful. thanks, Civil G

manner similar to thrust blocks, insofar as the reaction of the entire restrained unit of piping with soil balances the thrust force.
The mechanical joint uses the basic principle of the stuffing box and gland developed nearly 100 years ago and does not provide longitudinal restraint.

I have seen many instances where a thrust block was installed that wasn't big enough or where a restrained joint was used, but none of the joints on either side were restrained. In all the cases the joint failed either at the joint itself or at an adjacent joint in the pipe. It is very important to consider all factors when using either of these systems.
