Stuart,
 
The Petrozuata Upgrader (Venezuela) had that same problem. A few months after the installation of Delta Valves and bolted transition spools with side entry, the joint between the transition spool and the coke drum began to leak.
 
Last year the gasket was replaced with one manufactured by Chesterton, with good results, so far.
