: I'm putting together some training that includes steam distribution issues. Can someone tell me what the drain on a slip-type expansion joint is for? I haven't worked with these. My experience has been only with bellows expansion joints.
: Thanks much.
I think that it is for a grease fitting to help lube the piping and also seal the packing a little better
