Abstract
A flowline connection assembly connects first and second tubular members to each other. Each tubular member has an external flange on its end. A recess is formed in the bore at the end of each of the tubular members. A seal ring extends into each of the conical recesses. A clamp with two halves, each with cam surfaces that engage the flanges and pull the tubular members axially toward each other. Bolts extend from one clamp half into the other. A retainer ring on each bolt retains the bolts with one of the clamp halves.
