Abstract: A component used for drilling and operating hydrocarbon wells which is substantially tubular in form, and including a first end configured to be connected to a second end of another component also used for drilling and operating hydrocarbon wells. The first end includes a terminal portion including a first abutment surface configured to cooperate by interference with a corresponding abutment surface on the second end, and including a sealing surface configured to cooperate by interference with a corresponding sealing surface on the second end, the terminal portion being preceded by a threaded zone configured to be made up into a corresponding threaded zone of the second end. A compressible volume is provided in the thickness of the first terminal portion and partially beneath the sealing surface, to reduce radial stiffness of the terminal portion by at least 20%, while conserving at least 60% of axial stiffness.

Abstract: A directional hopper tee has a fluted interior vertical pipe that merges into a horizontal pipe. The horizontal pipe has an inlet that may receive bulk material, and subject to pressurized air that conveys the bulk material through the hopper tee. Bulk material may be discharged from a hopper through the vertical pipe, for conveyance for discharge from the horizontal pipe of the tee. A closure gate or door is provided through the bottom of the tee, generally in alignment with the vertical pipe, to allow for discharge or dropping of the granular material directly downwardly through and from the tee. The arcuate door is hinged on one side, and is locked by a cam lock on the opposite side, when located into closure against the bottom of the tee, but can be forced opened, through its cam mechanism, to provide for opening of the arcuate door and allow a direct downward discharge of the granular bulk material, from any hopper, and through the drop opening of the tee, as required.

The other clamp member has a pair of prongs defining a slot for receiving the shaft of the locking device, the locking element being engageable with the prongs to lock the clamp members to one another at ends thereof opposite the hinge-forming ends. The prongs each have at least one projection on a side facing away from the one clamp member. Each of the projections is disposed proximate the free end of the respective prong.

Abstract: A swivel misalignment coupling for connecting pipe sections in a high-pressure conduit. In one embodiment, the coupling is a three-bolt coupling having a female coupling member, a male coupling member, and a swiveling collar member. The male and female coupling members have contact surfaces that are spherical to enable sealing contact between them. A seal ring may be positioned between the contact surfaces to ensure a good seal. The collar swivels around the male coupling member to facilitate fastening of the collar to the female coupling member, which holds the male and female coupling members in sealing engagement. Recesses may be positioned radially inward from the attachment points (e.g., bolt holes) of the female coupling member to reduce stress and potential deformation of the contact surface.
