LIFTING AND GRIPPING
Lift the pipe above the slips and stop when the connection to be
broken out is at a comfortable height which will not induce bending
during breakout. Unlatch and remove the slip type elevators and
latch the single joint pick-up elevators to the joint that is to
be backed- out. Maintain vertical alignment of the pipe during breakout
with the help of the person on the stabbing board in the derrick.
BREAK-OUT
To minimize the chance of galling the connection, it is recommended
that the initial torque be applied slowly and then increased during
the initial break-out. Torque will be required for at least one
full turn after initial break-out of the connection. NSCT Premium
Connections are basically free-running after approximately one to
two full turns and the connections should be able to be backed out
with out torque interference after initial breakout. Back-out of
High Alloy connections should be carried out with the use of a strap
wrench or chain tong in basically the same manner as during the
make-up operation. The chain tong/strap wrench should be applied
after the connection has initially been broken out using the power
tongs as described above.
LAYING DOWN OF TUBULARS
If pipe is to be laid down, the joint should be carefully lowered
through the vee door, with a clean box and pin protector properly
installed on the tubular.
STORAGE OF TUBULARS
Connections that have been made-up and broken out or connections
that were cleaned and not used during running operations should
have either thread compound or a storage compound applied to the
threaded area of the connections. These compounds should cover the
entire seal, shoulder and the threaded area of the connection. Care
should be taken to assure that excessive amounts of moisture or
fluid are not inside of the pipe when it is placed in storage.
