AND THE USE OF TIN COATED COUPLINGS TO MAKE A
VIRTUALLY LEAK PROOF CONNECTION. IMPROVED THREAD TOLERANCES REDUCE
THREAD-TO-THREAD CLEARANCES. THREAD FEATURES ARE:
(C)
RUGGED, FIELD-PROVEN
BUTTRESS-TYPE THREAD PROVIDES DURABILITY AND HIGH TENSION STRENGTH.
(D)
RESTRICTED, FAVORABLE TOLERANCES
ENSURE SEALING AT END OF PIN.
(E)
DUCTILE PLATING ON COUPLING TO
IMPROVE SEALING, REDUCE TORQUE AND INHIBIT GALLING.
(F)
COMPATIBILITY WITH API
BUTTRESS THREADS AND RUNNING EQUIPMENT.
(G)
JOINT STRENGTHS AND INTERNAL
YIELD RATINGS EQUAL THOSE OF THE CORRESPONDING SIZE AND GRADE API BUTTRESS
CONNECTION.
(H)
COUPLING EXTENSION TO STIFFEN
AND REDUCE HOOP STRESS.
18.5
STAR SEAL -HW (HEAVY WALL) FOR THICK-WALL
HIGH-PRESSURE CASING HIGH-PRESSURE HIGH-TEMPERATURE (HP-HT) WELLS.
(PREMIUM)
(A)
SS-HW HAS BEEN RUN SUCCESSFULLY
IN STRINGS TO SET TO OVER 24,000 FT (7,300 M). SS-HW USES A NEAR PERFECT
BUTTRESS THREAD DESIGNED FOR WELLS WHERE MODERATE TO HIGH INTERNAL PRESSURE AND
HIGH-TENSION LOADS ARE CONCERNS.
SS-HW IS AVAILABLE IN OUTSIDE DIAMETERS FROM
5-1/2 THROUGH 14 INCHES IN WALLS FROM .500 TO .800 INCHES.
(B)
JOINT STRENGTH AND BURST RATING
ARE EQUAL TO 100 % OF PIPE BODY.
STAR SEAL-HW TAKES ADVANTAGE OF ITS SUPERIOR
SEALING ABILITY MADE POSSIBLE BY THE REDUCED CLEARANCES BETWEEN THREADS AND THE
USE OF TIN COATED COUPLINGS TO MAKE A VIRTUALLY LEAK PROOF CONNECTION.

OTHER IMPORTANT LONE STAR OILFIELD PRODUCT
APPLICATION SOLUTIONS DEVELOPED FROM FIELD WORK WITH CUSTOMERS AND TECHNICAL
EXPERTISE AND KNOW HOW FOR SEVERAL NICHE PRODUCTS INCLUDE:
19.1
SUBSEA PIPELINES - A SUBSET OF PIPELINES FOR
OFFSHORE USE USUALLY MADE TO CUSTOMER PROPRIETARY SPECIFICATIONS INSTEAD OF API
STANDARDS.
19.2
RISER WEAR SLEEVES - SACRIFICIAL WEAR RESISTANT
STEEL TUBE INSERTS TO PROTECT FOR OFFSHORE WELL DRILLING RISERS.
19.3
DRILLING TEMPLATES - PIPE FOR FABRICATED FRAMES
ANCHORED TO THE SEAFLOOR TO WHICH AN OFFSHORE PLATFORM MAY BE ATTACHED.
19.4
LINER HANGER TUBE - TUBE FROM WHICH TO CONSTRUCT A
MECHANICAL DEVICE TO ANCHOR A "LINER".
A LINER IS A CASING STRING THAT DOES NOT
EXTEND TO THE TOP OF THE WELLBORE, BUT INSTEAD IS ANCHORED OR SUSPENDED FROM
INSIDE THE BOTTOM OF THE PREVIOUS CASING STRING.
19.5
SAND SCREENS TUBES - TUBES UPON WHICH TO ASSEMBLE
SAND SCREENS.
SAND SCREENS ARE A METAL FILTER ASSEMBLIES USED TO SUPPORT AND
RETAIN WELLBORE FORMATION SAND OR THE SAND PLACED DURING GRAVEL PACK OPERATIONS.
19.6
JACK-UP LEG CHORDS - HIGH-STRENGTH STRUCTURAL PIPE
FOR STRUCTURAL MEMBERS FOR "JACK-UP RIG" LEGS.
A JACK-UP RIG IS A
SELF-CONTAINED COMBINATION DRILLING RIG AND FLOATING BARGE, FITTED WITH LONG
SUPPORT LEGS THAT CAN BE RAISED OR LOWERED INDEPENDENTLY OF EACH OTHER.
19.7
RIG MAST CHORD - MILD STEEL STRUCTURAL PIPE FOR THE
MAIN STRUCTURAL MEMBERS FOR DRILLING RIG "MASTS" - THE STRUCTURE USED TO SUPPORT
THE CROWN BLOCKS AND THE DRILLSTRING.
A LAND RIG MAST MUST HAVE VERY GOOD
STIFFNESS, BECAUSE IT WILL BE LAID DOWN WHEN THE RIG IS MOVED.
19.8
RIG MAST LACING - MILD STEEL STRUCTURAL PIPE FOR
THE STRUCTURAL MEMBERS FOR DRILLING RIG "MASTS" - THE STRUCTURE USED TO SUPPORT
THE CROWN BLOCKS AND THE DRILL STRING.
