PIPE &
THREADING CO.
FLUSH
JOINT CASING
Tight
clearance downhole requires a connection strong enough to do the job without a
coupling. Inter-Mountain Pipe Co. has sixteen years of experience in
helping our customers solve a variety of such problems in some very hostile
downhole environments. Whatever thread you choose, we'll make the
necessary crossovers and lift subs and we will provide it in the lengths
you need.
Inter-Mountain
Tapered Flush (IMTF) was designed so that the torque required to make the
connection would resist back-off during core drilling.
Inter-Mountain
Speed Casing (IMSC) features less taper (and thus less torque). As the
name implies, fewer threads per inch allow faster make-up. Also, Diamond
Core Drill Manufacturers Association (DCDMA) "W" series threads are
available.
Other customer-driven original designs
include Inter-Mountain Modified Sonic (IMMS), a coarse drill pipe thread
form which has been used for dry coring as well as casing, and
Inter-Mountain
Rope Thread (IMRT), developed for use with casing driver/advance systems and
usually ordered in a left-hand version. Both provide greater load-bearing
surface area and are particularly suited to heavy wall alloy steels and the
applications which call for their strength.
