A pipe element includes a pipe made of fiber-reinforced plastic and at least one metal connector, which is connected to the pipe in such a way that the connection can transmit torques and axial forces. The metal connector has a thread, in particular a conical thread, or a flange, by way of which thread or flange the metal connector can be screwed to another metal connector of an additional pipe element in order to connect two pipe elements. The metal connector surrounds the pipe on the outside by way of a connection region. A counter sleeve is present, which has contact with the inside of the pipe by way of a connection region. The metal connector and the counter sleeve each have a cylindrical thread, by way of which the metal connector and the counter sleeve are screwed to each other.

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 may comprise: a metal pipe portion extending from a first end to a first transition end and defining a first radially outer surface and a first radially inner surface, the first transition end comprising a first tooth element and a second tooth element disposed circumferentially adjacent to the first tooth element; and a polymeric pipe portion having a second transition end and defining a second radially outer surface and a second radially inner surface, the second transition end having a complimentary shape to the first transition end, the second transition end coupled to the first transition end.

A support assembly (20) is disclosed. The support assembly (20) comprises a mounting bracket (22) and a coupling component (24). The mounting bracket (22) comprises a first material and has an engagement surface (26) defining a void (28) along a first axis (30). The coupling component (24) comprises a second material, which is different than the first material. The coupling component (24) has a first end (32), a second end (34), and an intermediate portion (36). The intermediate portion (36) extends through, and partially fills, the void (28) defined by the mounting bracket (22). The intermediate portion (36) defines a fluid passageway (38) about the first axis (30) within the void (28) and also presents a locking surface (40). The locking surface (40) abuts the engagement surface (26) to prevent rotation of the coupling component (24) with respect to the mounting bracket (22).

A combination includes a plurality of segments attached to one another end to end around a central space. A channel is disposed between the sides of the segments. A sealing ring is positioned in the channels. A tube has a first end disposed within the central space. A first protrusion extends radially outwardly from the tube and limits the extent to which the tube can extend into the central space. The combination is configured such that an end of a pipe element may be axially inserted into the central space and fasteners can be tightened to draw the segments toward one another.

A coupling for joining a flanged pipe element to a non-flanged pipe element has segments that are connected end to end and surround a central space. Flange portions extend from one side of the segments. Each segment defines two channels, one of which receives a split ring for gripping the non-flanged pipe; the other channel receives a seal. A flanged tube is also positioned between the segments. The flange of the tube is positioned adjacent to the flange portions of the segments. The seal engages the tube and the non-flanged pipe element. The flange portions of the segments are bolted to the flange of the flanged pipe element and the flange of the tube is captured between the flanged portions of the segments and the flange of the flanged pipe element.
