API Spec 16R (R2010) PDF
Covers the design, rating, manufacturing, and testing of marine driller riser couplings. Coupling capacity ratings are established to enable the grouping of coupling models according to their maximum stresses developed under specific levels of loading, regardless of manufacturer or method of make-up. This specification relates directly to API 16Q, which covers the design, selection, and operation of the marine drilling riser system as a whole.
