Abstract:
This disclosure includes flow spool riser segment assemblies that are suitable for managed pressure drilling (MPD) and that can be lowered (e.g., when connected to other riser segment assemblies) through a rotary of a drilling rig. Some embodiments are configured to have portions of the flow spool connected (e.g., without welding) below the rotary.

Claim (Index 16):
The assembly of  claim 5 , where the fitting and the collar are configured to form a substantially gapless connection comprising:\n a female flange having an inward-facing conically tapered sealing surface; a male flange having an outward-facing conically tapered sealing surface; and a seal ring having an outward-facing conically tapered surface complementary to the sealing surface of the female flange and an inward-facing conically tapered surface complementary to the sealing surface of the male flange; where the seal ring is positioned between the male and female flanges with the conically tapered surfaces of the seal ring in contact with the complementary sealing surfaces of the male and female flanges and the male and female flanges are coupled together to form a connection between the primary lumen of the main tube and the fitting lumen of the fitting; where one of the collar and the fitting defines the female flange, and the other of the collar and the first defines the male flange and where an interface between male flange and the female flange is substantially free of gaps.
