A riser system with a primary conduit extends between a surface vessel and a subsea location and an auxiliary conduit that extends adjacent the primary conduit. In one example a composite jumper conduit extends from the surface vessel and is fluidly connected to the auxiliary conduit. The jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. In one example a subsea composite jumper conduit extends from subsea infrastructure and is fluidly connected to the auxiliary conduit. The subsea jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix.

A metallic-composite joint fitting is provided. The fitting may comprise a frustoconical internal bearing having a bore, a conical sleeve configured to be disposed about the frustoconical internal bearing, a composite structure configured to couple between the frustoconical internal bearing and the conical sleeve, a metallic end fitting configured to be disposed within the bore and couple to the frustoconical internal bearing, and an external nut configured to couple to the metallic end fitting and the conical sleeve, wherein at least one of the frustoconical internal bearing or the conical sleeve comprises a flanged portion mutually configured to couple the conical sleeve to the frustoconical internal bearing via a locking ring.

The invention relates to a plug assembly (1) comprising a tube (3) and a plug connector (4), which comprises a connector body (5), wherein the connector body (5) has an annulus (18) located between a first casing section (9) and a second casing section (12) of the plug connector (4), wherein the tube (3) is inserted into the annulus (18) of the connector body (5), characterized in that a tube compensating element is arranged between the tube (3) and the second casing section (12), wherein the first casing section (9) of the connector body (5) is deformed such that an interlocking connection is established between a forming region (25) of the first casing section (9) of the connector body (5) and the tube (3), wherein the tube compensating element is clamped between the tube (3) and the second casing section (12).

An isolation valve unit with a fusion outlet including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port from which the fusion outlet extends. In one embodiment, the thermoplastic end is composed of a PP-RCT material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to couple to a larger polymeric pipe and to control the flow of fluids in a plumbing system via actuation of the ball valve.

The connector assembly includes a housing with an open bore which extends along an axis from an open first end to an open second end. The housing further includes a plurality of fingers that are spaced circumferentially from one another and are deflectable in a radial direction. At least one of the fingers has a plurality of teeth that are spaced axially from one another and extend into the open bore of the housing for biting into the first tube to resist pull out of the first tube from the open bore. Each of the teeth also extends by a height to a leading edge of an engagement surface which also includes an angled portion that extends at an angle relative to the axis. The axially spaced teeth have at least one of differing heights and differing angles of the angled portions.

A connecting joint includes a connecting tube and a first compression sleeve. The connecting tube includes a first tube connecting section for connecting a first tube and a second tube connecting section for connecting a second tube. The first tube connecting section and the second tube connecting section are communicated and an annular connecting plate is arranged therebetween. The first compression sleeve is sleeved on the second tube connecting section. A first insertion hole is formed between an inner wall of the first compression sleeve and an outer wall of the second tube connecting section. A first annular groove is formed in an outer surface of one end of the second tube connecting section. An end portion of one end of the first compression sleeve close to the annular connecting plate is bent toward the second tube connecting section and inserted into the first annular groove.
