(A)
LSS CASING VI IS PROPOSED NEW
PROGRAM.
IT IS NOT INTENDED FOR LICENSE OR SALE.
ALTHOUGH CASING VI WILL
INCORPORATE ALL OF THE CAPABILITIES OF LSS CASING II-IV, IT WILL ADD LOAD
RESISTANCES FACTOR DESIGN (LRFD) METHODOLOGY
BASED ON ISO TR-10400.
(B)
LRFD II WOULD COMBINE ISO
TR-10400 CONSTITUTIVE EQUATIONS AND OTHER PROPRIETARY LIMIT STATE FUNCTIONS WITH
PERFORMANCE PARAMETERS TO QUANTIFY THE RESISTANCE.
STATISTICAL ANALYSIS AND
MANUFACTURING PROCESS KNOWLEDGE ARE THEN APPLIED TO DETERMINING THE STOCHASTIC
PERFORMANCE OF THE POPULATION.
LOT PERFORMANCE WOULD EVALUATED STATISTICALLY
AND IS UNDERSTOOD BY CONSIDERING THE MANUFACTURING PROCESS.

Improved threading of API Connections
17.1
API SR22
Users and manufacturers can meet API requirements for connection tolerances and
still potentially have connections with very limited leak resistance.
This
deficiency and API 8-Round connections is now addressed by API SR22 to provide a
reliable performance-based connection that is fit for purpose.
Gauging methods
are changed, leak resistance ratings incorporate the effect of tension, makeup
criteria include both torque and position aspects, and connection tolerances are
improved.
17.2
SR22 SPECIFICATIONS ADDRESS DIMENSIONS, GAUGING,
COUPLING SURFACE TREATMENT, THREAD FORM, MAKEUP, AND OPTIONAL ID BORE

THE KEY API LTC PERFORMANCE PARAMETERS ARE:
(A)
TURNS MAKEUP,
(B)
THREAD TAPER,
(C)
COUPLING OD AND
(D)
THREAD FORM.
17.3
THE NUMBER OF TURNS OF MAKEUP REQUIRED VARIES
DEPENDING ON DIAMETER AND GRADE.
IMPORTANT MAKEUP PARAMETERS ARE:
(A)
THREAD COMPOUND AND
(B)
SURFACE FINISH TO AVOID GALLING
(TIN PLATING OR PHOSPHATING, FOR EXAMPLE)
(C)
AND SEAL CLEARANCES IN THE
THREAD FORM.
17.4
TIN PLATING IS REQUIRED ON C90 AND HIGHER GRADES
FOR IMPROVED LEAK RESISTANCE.
17.5
ADVANTAGES OF SR22 INCLUDE:
(A)
QUANTIFIABLE PERFORMANCE-BASED
RATING;
(B)
ROOT CAUSE FAILURE ANALYSIS;
(C)
IMPROVED ACCURACY AND
REPEATABILITY OF PITCH DIAMETER (PD) MEASUREMENT.
