LAND RIG MAST MUST HAVE VERY GOOD
STIFFNESS, BECAUSE IT WILL BE LAID DOWN WHEN THE RIG IS MOVED.
19.9
BLAST JOINTS - THICK-WALLED AND/OR CARBIDE-COVERED
TUBES WHICH ARE RUN WITH OCTG TUBING STRINGS OPPOSITE PERFORATIONS IN DUAL
COMPLETIONS OR DIRECTLY BELOW THE TUBING HANGER IN SAND FRAC SITUATIONS, TO
MINIMIZE THE EFFECT OF EXTERNAL EROSIVE ACTION.

DH PUMP BARRELS - TUBES FOR DOWNHOLE (DH) PUMP BARRELS.
DH PUMPS ARE PART OF AN ARTIFICIAL-LIFT SYSTEM THAT USES ELECTRICALLY DRIVEN
SUBMERSIBLE CENTRIFUGAL PUMP SPECIFICALLY CONFIGURED TO SUIT THE PRODUCTION AND
WELLBORE CHARACTERISTICS OF A GIVEN APPLICATION.
19.11
DH PUMP PARTS - TUBES FOR DOWNHOLE (DH) PUMP PARTS.
DH
PUMPS ARE PART OF AN ARTIFICIAL-LIFT SYSTEM THAT USES ELECTRICALLY DRIVEN
SUBMERSIBLE CENTRIFUGAL PUMP SPECIFICALLY CONFIGURED TO SUIT THE PRODUCTION AND
WELLBORE CHARACTERISTICS OF A GIVEN APPLICATION.
19.12
MUD PUMP PARTS - TUBES FOR PARTS FOR OIL AND GAS WELL
DRILLING FLUID (MUD) PUMPS.
19.13
TOP DRIVE COMPONENTS - TUBES FOR A TOPDRIVE, THE DEVICE
THAT TURNS THE DRILLSTRING. TOPDRIVES CONSIST OF ONE OR MORE MOTORS (ELECTRIC OR
HYDRAULIC) CONNECTED WITH APPROPRIATE GEARING TO A SHORT SECTION OF PIPE CALLED
A QUILL, THAT IN TURN MAY BE SCREWED INTO A SAVER SUB OR THE DRILLSTRING ITSELF.
THE TOPDRIVE IS SUSPENDED FROM THE HOOK, SO THE ROTARY MECHANISM IS FREE TO
TRAVEL UP AND DOWN THE DERRICK. THIS IS RADICALLY DIFFERENT FROM THE MORE
CONVENTIONAL ROTARY TABLE AND KELLY METHOD OF TURNING THE DRILLSTRING BECAUSE IT
ENABLES DRILLING TO BE DONE WITH THREE JOINT STANDS
INSTEAD OF SINGLE JOINTS OF PIPE. MODERN TOPDRIVES ARE A MAJOR IMPROVEMENT TO
DRILLING RIG TECHNOLOGY AND ARE A LARGE CONTRIBUTOR TO THE ABILITY TO DRILL MORE
DIFFICULT EXTENDED-REACH WELLBORES.

NOTE THAT THE ABOVE PRODUCTS DESCRIBED INCLUDE TUBES
MADE THE BY THE DRAWN OVER MANDREL (DOM) PROCESS AND PIPE.
ALSO, THAT MPM'S
EQUIPMENT LIMITATIONS MAY EXCLUDE CERTAIN OF THESE PRODUCTS.

MECHANICAL TUBING PRODUCTS AND PROCESSES
20.1
DRAWN OVER MANDREL (DOM) PRODUCTION TECHNOLOGIES.
(A)
COLD DRAWN OVER MANDREL (DOM) -
TUBING IS PULLED BOTH THROUGH A DIE AND OVER A MANDREL TO ACCURATELY AND
PRECISELY SIZE THE TUBE'S OD, WALL AND/OR ID DIMENSIONS. TUBES PRODUCED BY THE
DOM PROCESS RESULTS IN CLOSER TOLERANCES, SMOOTHER SURFACES, AND GREATER
STRENGTH. IN ADDITION TO ROUND TUBES, SHAPES SUCH AS SQUARES, HEXAGONS, OVALS,
AND RECTANGLES CAN BE PRODUCED.
(B)
QDOM - QUENCHED AND TEMPERED
HIGH-STRENGTH DOM TUBING FOR APPLICATIONS
THAT REQUIRE VERY HIGH STRENGTH AND
HIGH TOUGHNESS (CVN).
20.2
PUSHBENCH AND OTHER METHODS OF DRAWING SMALL
DIAMETER TUBING.
(A)
A "PUSHBENCH", FOR THE PURPOSES
OF VALIN MPM, IS A COMPACT REPLICATABLE DRAW SHOP FOR THE COLD FINISHING SHORT
AND MEDIUM LENGTH 10 FT (3M) TUBES.
(B)
THE PUSHBENCH FUNCTIONS SIMILAR
TO A MACHINING CELL.
(C)
BEYOND GENERAL MANUFACTURING
PUSHBENCHS MAY OFFER PARTICULAR ADVANTAGE
FOR FINISHING AUTOMOTIVE TUBULARS FOR
SUSPENSION, TRANSMISSION AND STEER APPLICATIONS AND POSSIBLY DOOR INTRUSION
BEAMS.
(D)
DOM NICHE PRODUCTS INCLUDE:
(E)
PERFORATING GUN TUBES - TUBES
FOR A DEVICE USED TO PERFORATE OIL AND GAS WELLS IN
