What is the pipes made for delivery made from and how are they connected? The problem I have is that the honey line was a food grade plastic line with reinforced mesh in the plastic. When the honey in the line was much colder than the honey in the tank where it was being pumped from (which can happen first thing in the morning if the pipe is on a cold floor) it put very much pressure (because its a gear pump) on the plastic pipe where it was connected. It blew the hose off a few times. Now it is on with three hose clamps. But also it has exploded the pipe several times. We have to be very careful when we turn it on under conditions when the pipes have gotten cold (and now they are off the floor). We just give it a few seconds on and then stop. Then a few more...... Until the honey is moving and warm in the pipes. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
