CI to DO connection
CI to DO connection
(OP)
HI
We have a sewer forcemain retrofit situation in which we are trying to connect ex. 24" CI pipe to new 24" DI pipe (force main with 50 psi pressure). We are using solid sleeve to connect the CI to DI pipe but want to restrain the whole assembly. I am aware that it is not possible to restrain CI pipe completely but is there some what restrain system (coupling) avaibale than not having restrain at all.
Any thoughts would be greatlt appreciated.

CI pipe can certainly be restrained. Bell clamps and tie rods work for both DIP and CIP. I guess you're suggesting using MJ restraint glands (mega lugs if you will) for the side with new DIP but don't want to use them on the older CIP. That might be a good choice, but the material manufacturers of the MJ gland restraints have products that work on CIP. Use tie rods if you're worried ... but maybe the older CIP is in bad enough shape that even these would be a problem?
