Abstract:
A pair of adjacent components from a containment system for fluids at pressures in excess of 15,000 psi, providing a seal between the adjacent components without the need for an insert therebetween, the adjacent components being aligned along a coupling axis, the pair of adjacent components comprising:a tapered female mouth integrally formed on one of the adjacent components, the tapered female mouth having a female mating portion; and a tapered male mouth integrally formed on the other of the adjacent components, the tapered male mouth having a male mating portion sized to contact the female mating portion; wherein: one of the male and female mating portions has a substantially linear cross-sectional profile, the linear cross-sectional profile being angled between 40 and 68 degrees from the coupling axis; and the other of the male and female mating portions has a convex, curved cross-sectional profile, the curved cross-sectional profile contacting the linear cross-sectional profile in a substantially circular seal, the contact engagement of the male and female portions substantially reducing relative motion between the portions during system operation.
