A method of manufacturing a composite connector for a fluid transfer conduit is provided which comprises applying continuous fibre reinforcement, oriented at least partially circumferentially and pre-impregnated with a thermoplastic polymer to a tubular mould portion which extends substantially parallel to a central axis C; applying at least one further mould portion to form a complete mould in which the continuous fibre reinforcement is enclosed and injecting a thermoplastic polymer into the mould to form a connector with a tubular hub portion and a flange portion which extends from the hub portion at an angle to the central axis C. The tubular hub portion comprises a tubular seal section with an inner layer and an outer wherein the inner layer comprises the continuous fibre reinforcement and the outer layer comprises the injected thermoplastic polymer.

The present embodiments relate to a novel clamping assembly. More specifically, present embodiments relate to a clamping assembly for blind flange installation which provides an air tight seal for piping applications including, but not limited to, low pressure high-density polyethylene (HDPE) piping applications.

A fitting is attached to a composite pipe by inserting a tubular root portion of the fitting into an end of the pipe and then tensioning longitudinally-extending tensile elements distributed around the fitting. This moves an outer wedge component of the fitting longitudinally relative to the pipe to force an opposed inner wedge formation radially inwardly toward the roof portion, clamping the fitting to the pipe. The fitting may be an end fitting to enable the pipe to be joined to another pipe or conduit, or may be an in-line fitting used to join two lengths of pipe end-to-end.

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.

Flange connection for connecting two pipeline ends made of plastics material and method for assembly, containing two mutually opposing pipe ends (2) made of plastics material, wherein the pipe ends each have a prewelding neck, two loose type flanges, wherein a loose type flange is arranged at each pipe end, wherein the loose type flanges have holes for mutual clamping, clamping means, wherein the clamping means are arranged in the holes and serve to mutually pull together the loose type flanges and the pipeline ends, and a sealing element, wherein the sealing element comprises a conductive plastics material and exclusively one material.

An apparatus, system, and method for tapping and reinforcing a valve of a liner lined host pipe with a fitting device assembly that includes a service sleeve having a flange, a cylindrical body, and an engaging end and a reinforcing sleeve having a flange, a cylindrical body, an engaging end having at least one annular ratchets configured to engage with the engaging end of the service sleeve in order to secure the service sleeve and the reinforcing sleeve together, and a plurality of cutouts in the cylindrical body. A cork assembly that includes the service sleeve and a cork having at least one radial appendage is inserted into the valve, then the host pipe is lined with a liner. The cork assembly is the located, and the cork is removed from the cork assembly. The reinforcing sleeve is then installed into the service sleeve in the valve.
