    摘要： A method of forming a pipe joint between a pipe section and a pipe fitting includes inserting an end of the pipe section into a socket of the pipe fitting, and attaching a removable clamp to the pipe section and pipe fitting. The socket includes a centering device and a pipe stop that is configured to receive the end of the pipe section. The clamp includes a plurality of arcuate segments and a tightening mechanism, and each arcuate member has a removable/replaceable sealing member. The arcuate members are radially compressed via the tightening mechanism to cause the respective sealing members to seal an open end of the gap. A bonding agent is then injected into the gap via a port that extends through the pipe fitting. Once the bonding agent has been injected, the clamp is removed and can be reused.

    摘要： A coupling for pipe-in-pipe pipeline tubing formed of an assembly of sections each incorporating an inner pipe and an outer pipe butt welded to the inner pipe, two successive sections being joined together by the welding of respective inner pipes delimiting a segment of inner pipe, wherein it is formed by a sleeve arranged perpendicularly to the segment and a filler material constituted by a quick-set mortar based on aluminous cement and sand, said filler material being arranged in the free space delimited by the sleeve, said segment and the outer pipes of two successive sections.

    摘要： Techniques for implementing a pipeline system including a pipe segment and a potted pipe fitting. The pipe segment includes tubing having an internal pressure sheath layer, a reinforcement strip, and an outer sheath layer. The potted pipe fitting includes an outer fitting body disposed around a portion of the reinforcement strip, an inner fitting body disposed between the portion of the reinforcement strip and the internal pressure sheath layer, in which the inner fitting body directly abuts the internal pressure sheath layer at least up to a point where the reinforcement strip begins to flare away from the internal pressure sheath layer and a potting cavity of the potted pipe fitting is defined at least between an inner surface of the outer fitting body and an outer surface of the inner fitting body, and cured potting material implemented around the portion of the reinforcement strip in the potting cavity.

    摘要： A sprinkler assembly includes a sprinkler body and a tubular connection fitting. The tubular connection fitting includes a first end for connection to a fluid supply pipe and a second end with the sprinkler body inserted therein, the tubular member including an outer surface and an inner surface defining an internal conduit extending along a longitudinal axis, the inner surface of the tubular member includes a first stop surface spaced from the first end to define an insertion depth for the fluid supply pipe and a second stop surface to limit insertion of the sprinkler body into the second end. The first stop surface defines an annular channel for housing an end of the fluid supply pipe.

    摘要： 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.

    摘要： A flexible pipe fitting for joining a first length of pipe to a second length of pipe at an arbitrary angle is provided. The apparatus includes a primary fitting having a substantially circular opening at a first end thereof for receiving an end of a first length of pipe, and an enlarged opening at a second end thereof for receiving a first flexible coupling member. The first flexible coupling member includes an outer wall having an outer surface engaging an inner surface of the enlarged opening, and an inner wall having a lower end connected to a lower end of the outer wall. The inner wall further includes a substantially circular opening therein for receiving a second, rigid member. The inner surface of the second, rigid member is configured to receive an end of the second length of pipe. The enlarged opening in the primary fitting is preferably fish-mouth shaped, or alternatively, cone shaped. Adhesive, such as PVC cement may be used to bond the various fittings, and lengths of pipe together to form a sealed joint.
