A member joining method includes: a placement process of arranging a first member and a second member inserted into the first member so that a gap surrounding the second member is provided between the first member and the second member; a filling process of filling a molten resin into the gap and applying pressure to the resin so as to cause at least one member of the first member or the second member to undergo elastic deformation; and a pressure maintaining process of maintaining the pressure until the resin that has been filled into the gap has cured.

An apparatus for an airship, including: a spacer ring adapted to couple to a joint opening of a joint, the spacer ring having multiple internal protruding portions adapted to form a gap between the spacer ring and a connector inserted into the joint; an injecting clamp adapted to clamp around a first portion of the spacer ring, the injecting clamp having an injecting hole for receiving an adhesive and an outlet for injecting the adhesive to fill a space formed between the joint and a portion of the connector inserted into the joint; and a heating clamp adapted to clamp around a portion of the joint that surrounds the portion of the connector inserted into the joint, the heating clamp including a heat source adapted to heat the adhesive in the space formed between the joint and the portion of the connector during a curing process.

One aspect is an apparatus including a first node including a first bonding surface and a second node including a second bonding surface. The apparatus includes a feature configured to accept an adhesive and an adhesive channel coupled to the feature configured to accept the adhesive. The apparatus includes a shear joint coupling the first node and the second node, the shear joint configured to receive the adhesive in an adhesive region formed by the first bonding surface and the second bonding surface, the adhesive for coupling the first bonding surface to the second bonding surface through the feature configured to accept the adhesive.

Described herein are gasketed pipe joints. In some embodiments, a joined pipe assembly is provided that includes: a first pipe having a first end portion with a first outer diameter and a first inner diameter; a second pipe having a second end portion with a second inner diameter and a second outer diameter, wherein the second end portion nests within the first end portion; wherein the first end portion includes a circumferential recess, and wherein an inner surface of the recess is located radially outward of the first inner diameter to form a pocket; and an adhesive gasket positioned in the pocket and adhered to the inner surface of the recess and the second outer diameter.

A pipe coupling is provided for securing end portions of a pair of thermoplastic pipe elements together. The pipe coupling comprises a first half-shell and a second half-shell for receiving the pair of thermoplastic pipe elements, each one of the half-shells comprising a pair of contact surfaces facing the central space; a pivot attachment pivotally connecting the half-shells to one another at the pivoting ends and enabling the half-shells to pivot with respect to one another between a closed state and an open state; a first connector positioned at the connecting end of the first half-shell; and a second connector positioned at the connecting end of the second half-shell, the first connector and the second connector being complimentary to one another and connectable to each other when the half-shells are in the closed state to enable the welding solvent to sealably weld the contact surfaces and the pipe elements together.

A method of borehole pipe installation begins with unfinished stick pipes brought to the installation site and then machined or cut to form male and female ends. The pipe ends are then locked together to form a flush joint. The lock can be provided via a groove cut into one of the ends for receipt of a lock gasket, which secures and seals the joint when the pipes are pushed together, and prevents the pipes from being pulled apart. Alternatively, to the groove and lock gasket, the ends can be glued and screwed together, with the screws allowing the joined pipes to be pulled through the borehole before the glue is dry. The pipe joint has flush exterior and interior surfaces to minimize borehole clearance and maximize fluid flow through the pipe assembly.

A liquid junction assembly for providing a flow connection between two tubular conduits. The assembly includes respective bodies configured to define elongated passages of respective first and second cross sections to receive and locate the respective tubular conduits, a plate with at least one hole therethrough of a third cross section smaller than the first and second cross sections, and a seat for the plate, defined in a face of one or both of the bodies. The bodies and the plate are assembled with the plate in the seat and the elongated passages and the hole aligned along a common axis.

An apparatus for an airship, including: a spacer ring adapted to couple to a joint opening of a joint, the spacer ring having multiple internal protruding portions adapted to form a gap between the spacer ring and a connector inserted into the joint; an injecting clamp adapted to clamp around a first portion of the spacer ring, the injecting clamp having an injecting hole for receiving an adhesive and an outlet for injecting the adhesive to fill a space formed between the joint and a portion of the connector inserted into the joint; and a heating clamp adapted to clamp around a portion of the joint that surrounds the portion of the connector inserted into the joint, the heating clamp including a heat source adapted to heat the adhesive in the space formed between the joint and the portion of the connector during a curing process.

A pipe coupling assembly for joining two sections of polymer pipe, the pipe coupling assembly comprising: an insert configured for positioning within an end region of a first section of polymer pipe and an end region of a second section of polymer pipe, such that an annular gap is formed between the insert and the end regions of polymer pipe; an adhesive configured for sealing the annular gap between the insert and the end regions; and an external coupler for positioning over the end regions and joining the first and second sections of polymer pipe.
