This report describes a series of experiments which were undertaken to determine the reduction in noise power radiated from heating radiators when flexible couplings are inserted in the feed pipes.

Quick replacement of broken GRP pipes is provided using pre-assembles STRAUB pipe couplings. Absorbing a gap of more then 30mm between pipe ends, STRAUB-FLEX 3 couplings make it easy-to-nstall spool ...

all the new couplings. Most drain systems use rigid pipes fairly large in diameter. You can't flex them enough to slide on that last fitting and get it to seat fully. Rather than struggle with ...
