RE: Unheading Valves


Claus Graf

The addition of a FW TUD in older cokers will:
1.- Improve the ergonomic position when removing the top head bolts.
2.- Eliminate a trip hazard, as sometimes the top flange is less than a foot above the top deck.
3.- Allow the operator to remotely open the top head (after removing the bolts).
4.- Additional drill stem guide & cover with automatic locking device can be incorporated to keep the cutting tool inside the drum.
Anything that can be done to keep the operators away while doing these activities will improve safety.
