What exactly is a puddle flange?
(OP)
I am examining an application where a pipe running through an underground pit has a puddle flange joining the pipes within the pit wall. My understanding is that the puddle flange will prevent the passage of liquid from one side of the wall to the other (external to the pipe). However a colleague of mine has suggested that depending on the welding of parts of the flange, it's purpose is to prevent wall cracking in the event of pipe movement. I'd appreciate if somebody could give me a definition, or tell me if a puddle flange serves more than one purpose.
Thanks in advance

I feel the puddle flanges will add to wall cracking in case of pipe movement.

Thanks a lot for those replies, they cleared things up for me here.

Check out a product called "Linkseal" for another way of sealing the joint.

Care must be taken as the tape can swell and burst the concrete locally. ie the concrete has to be sufficiently thick.
Concrete does shrink away from the stainless steel or ductile iron puddle flange. The puddle flange must be able to withstand the sustained and occassional loads applied to the flange.
