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.

The assembly according to claim 1, wherein while one of the bolts is in the inner position and fully in threaded engagement with one of the threaded bores, the other of the bolts may be moved to the outer position, fully disengaged from the other of the threaded bores. 3. The assembly according to claim 1, wherein each of the holes in the first clamp half has an enlarged counterbore that joins the restricted diameter portion, defining a shoulder facing inward. 4. The assembly according to claim 3, wherein the restricted diameter portion in each of the holes in the first clamp half comprises an inward-facing shoulder that is located closer to an outer end of the hole than an inner end of the hole. 5. The assembly according to claim 1, a distance from the inner position to the outer position is at least equal to a depth of the threaded bore. 6. The assembly according to claim 1, further comprising: a chamfer formed at an intersection of each of the end faces with each of the flanges of each of the tubular members; a rib formed in an inner side of each of the clamp halves parallel to and equidistant between the cam surfaces, the rib having inclined flanks that extend to a crest; and when the tubular members are fully made up to each other, a clearance exists between each of the flanks and one of the chamfers, the clearance being substantially constant through the axial length of each of the flanks. 7. The assembly according to claim 1, further comprising: a chamfer formed at an intersection of each of the end faces with each of the flanges of each of the tubular members; a circumferentially extending rib formed in an inner side of each of the clamp halves equidistant between the cam surfaces, the rib having converging flanks; and wherein an included angle between the flanks is substantially equal to an included angle between the chamfers when the tubular members are connected to each other. 8. The assembly according to claim 1, further comprising: a rib formed in an inner side of each of the clamp halves parallel to and equidistant between each of the cam surface, the rib having flanks on opposite sides that converge toward each other and terminate in a crest; a pair of concave recesses in each of the clamp halves, each of the recesses being located between one of the cam surfaces and one of the flanks of the rib; and wherein the recesses of the clamp halves define a maximum inner diameter that is 10 to 20 percent greater than an inner diameter defined by the ribs of the clamp halves when the tubular members are connected. 9. The assembly according to claim 1, wherein an outer diameter of each of the flanges divided by an axial length of each of the flanges is in the range from about 3.00 to about 7.10. 10. The assembly according to claim 1, further comprising: a passage extending through each of the tubular members, each of the passages having a counterbore at a junction with the end face; a seal ring extending into each of the counterbores for sealing the passages between the two tubular members; and wherein an outer diameter of each of the flanges divided by an inner diameter of the seal ring is in the range from about 1.5 to about 2.10. 11. A flowline assembly comprising: first and second tubular members having a common longitudinal axis when connected; an end portion on each the tubular members having a flow passage terminating in a flat end face; an external annular flange on each of the end portions, each of the flanges having a tapered surface axially spaced from the end face; a counterbore formed in the passage of each end portion and extending axially from the end face; a seal ring extending into each other counterbores when the tubular members are connected; a pair of clamp halves, each having axially spaced apart internal cam surfaces that engage the tapered surfaces of the flanges on the end portions; a fastener for securing the clamp halves to each other; wherein when the tubular members are connected together, each of the flanges has an outer diameter divided by an axial length that is in the range from about 3.00 to about 7.10; and the outer diameter of the flanges divided by an inner diameter of the seal ring is about 1.50 to about 2.10. 12. The assembly according to claim 11, further comprising: a chamfer formed at an intersection of each of the end faces with each of the flanges of each of the tubular members; a circumferentially extending rib formed in an inner side of each of the clamp halves equidistant between the cam surfaces, the rib having converging flat flanks; and wherein an included angle between the converging flanks is substantially equal to an included angle between the chamfers when the tubular members are connected to each other. 13. The assembly according to claim 11, further comprising: a flat chamfer formed at an intersection of each of the end faces with each of the flanges of each of the tubular members; a circumferentially extending rib formed in an inner side of each of the clamp halves equidistant between the cam surfaces, the rib having converging flat flanks; and wherein each of the chamfers has substantially the same axial length as each of the flanks. 14. The assembly according to claim 11, further comprising: a circumferentially extending rib formed in an inner side of each of the clamp halves equidistant between each of the cam surface, the rib having flanks on opposite sides that converge toward each other and terminate in a crest; a pair of concave recesses in each of the clamp halves, each of the recesses being located between one of the cam surfaces and one of the flanks of the rib; and wherein the recesses of the clamp halves define a maximum inner diameter that is 10 to 20 percent greater than an inner diameter defined by the ribs of the clamp halves when the tubular members are connected. 15.
