RE: Leaking



Which or where are the damage in the rotary, is at the bearing or in the packing? in our units the leak coming from packing, change the packing use to take 4 or 5 hours, if the damage are the bearing, (if I remember are 4 for flowserve system) you can take a look for the way of the operator is cutting the coke, too fast the tool hit the coke and this can produce that the bearing  get damage. We had this problem few years ago, and we talk with they in order to cutting the pilot (hole) with a velocity of 2 3 feet for minute. this reduce this fail in almost 99 %
