Abstract
A rotary joint for a decoking tool. The rotary joint includes a seal assembly that has one or more primary seals and one or more secondary seals. The secondary seals become operative upon the presence of a leak in the primary seals such that the rotary joint can continue to be used until a scheduled maintenance outage. A selective vent is used to route leaking fluid so that one or the other of the primary and secondary seals can be activated.
