The HSC® Premium Connection threaded and coupled system was developed to meet the needs of the Oil and Gas Industry.
The design phase of HSC® Premium Thread Connection System employs various computer-oriented tools. Software images are created and subjected to Finite Element Analysis validated by the production of prototypes submitted to a programme of stringent mechanical testing (developed from APIRP5C5).
These tools, in addition to classical design methodology, are used to optimize crucial features of the joint (such as thread & seal interference and geometry) prior to “cutting metal”.
This highly successful premium connection is manufactured using the most modern machine-tool technology and gauging system.
Maximization of product control and the accompanying close tolerancing ensure ultimate joint performance through consistency in make-up, elimination of snagging and improved running times. Verification of results of multiple made-up joints through in-field monitoring (using specialized torque-monitoring computer equipment) demonstrates excellent correlation with analysis predictions.
HSC® was quickly established as a consistent, reliable, and cost-effective threaded and coupled Premium Connection system,
What are the main characteristics of the HSC® Premium connection system?
Close Tolerances
HSC® uses state-of-the-art CNC machine tools and proven manufacturing systems to produce a high quality and close tolerance product, minimizing field problems.
Smooth Running, Consistency in manufacturing of HSC® products ensures repeatable make-up readings, both in thread and seal torque, resulting in improved running times and less snagging.
Inside the Joint
The 6 degree machined taper of the pin profile mates with the closely controlled bore of the HSC® coupling to allow very smooth product flow and no hang-ups of down-hole tooling.
Gas Tight Seals
Both HSC® tubing and casing metal to metal seal and torque shoulders ensure stored energy within the connection.
Testing
The HSC® tubing and casing performance and its interchangeability with other premium connections with similar thread profiles are fully proven by a stringent mechanical testing programme using helium-based pressure testing with multiple make and break checks (developed from API RP5C5). The tests have been supported by a series of rigorous field trials.
The Pin Thread
The HSC® pin has the classic Buttress profile, 3° load flank and 3/4″ per foot taper with full thread “run-out”.
The Coupling
The HSC® coupling is available in outside diameters to meet the following specifications:
ES Equal Strength
R Regular
SC Special Clearance
SB Special Bevel
The long coupling design ensures that the pin “run-out” thread on the pipe is always contained within the coupling thus ensuring that the tensile strength of the HSC® joint is at least equal to the pipe body. The long J-Section allows greater distribution of stress.
Anti-Galling Treatment
A high specification HSC® anti-galling surface treatment is applied to both pin and coupling. Extensive testing has proven that the occurrence of galling is reduced to an absolute minimum for assemblies of components using this preparation.
Gas Tight Seals
Both HSC® tubing and casing metal to metal seal and torque shoulders ensure stored energy within the connection.
