Prior to 1998, API RP 5C5(1) was used to qualify connections. Since 1998, SEPCo has been qualifying connections consistent with ISO 13679:2002(2).These connections have been qualified by testing, by product line qualification, or through extrapolation/interpolation from fully tested connections. In light of the potential for corrosion on metallic surfaces or handling damage, SEPCo requires that the connections for wells above 8,000 psi have two different types of sealing mechanisms: a metal seal and an independent resilient seal. Qualification and usage of tested connections with two proven seals has resulted in only four connection issues in wells (all attributed to incorrect rig make-up) over the last 20 years.The actual connection test data are the property of the thread design company. For details of any of the test protocols and results, the appropriate thread design company should be contacted.Qualification MethodAppendix A lists connections which SPECo uses for well service above 8,000 psi differential pressure. In many cases these connections are rated to much higher pressures; some are rated to 15,000 psi and 18,000 psi. Similarly, all of these connections have maximum pressure ratings (above 8,000 psi), and the load-pressure usage envelopes are different for the respective connections. Details of these ratings are available from the thread design companies.ISO 13679:2002, an industry test protocol to qualify connections, is used by SEPCo to qualify connections. ISO 13679 testing requirements include internal and external pressure, tensile and compressive loading, bending and elevated temperature tests.
