A connection apparatus suitable for mounting on a structural element and connection to a port of a system or component in which the connection apparatus comprises a connector, a flange and a compressible biasing means is provided. The connector forms a longitudinally extending conduit having an axis (A) extending along the centre of the conduit, a port end adapted to be engaged with the port of a system or component, and a second end. The connector comprises a shoulder extending around the perimeter of the connector, and the shoulder extends around the perimeter of the connector in a direction substantially perpendicular to the portion of the conduit axis (as) around which the shoulder extends. The biasing means is adapted to at least partially extend around a portion of the connector adjacent to the shoulder.

A fracturing manifold system includes a first manifold assembly in a side-by-side arrangement with a second manifold assembly. The first manifold assembly includes a plurality of first junctions, each having multiple inlet ports facing a first side of the fracturing manifold system. The second manifold assembly includes a plurality of second junction, each having multiple inlet ports facing a second side of the fracturing manifold assembly. Inlet ports on a single junction may be angled relative to each. The inlet ports may also be angled relative to a manifold flow path.

A method of manufacturing a joint flange using a thickness-increased, machined pipe is provided. The method includes a pipe cutting operation in which a pipe is cut to a predetermined length, a flange forming operation in which a flange having a mounting hole for installing the pipe is formed by die casting, a bump-forming operation in which a thickness-increased part, which is formed by increasing a thickness of one end of the pipe, is bumped to form a first bead locked to the flange, a machining operation in which a circumference of the thickness-increased part is machined to form a sealing groove having an O-ring installed, and a fixing operation in which the pipe is inserted in the mounting hole of the flange and the other end of the pipe is pressed to form a second bead so that the pipe is pressed to a lower end of the flange.

A clamp includes a first clamp body portion arranged for removable coupling about a generally cylindrical support structure to a second clamp body portion. The first clamp body portion includes a first clamp structure containing a first generally semi-spherical floating bushing, the first generally semi-spherical floating bushing coupled to the first clamp structure. The second clamp body portion includes a second clamp structure containing a second generally semi-spherical floating bushing, the second generally semi-spherical floating bushing coupled to the second clamp structure.

A piping system for oil and gas in very deep water includes two opposing flanges and a seal ring between the flanges. Each flange has an annular ridge between concentric grooves. The seal ring has a radial web that connects longitudinal inner and outer sealing portions, which are received in the concentric grooves with the annular ridge received sealingly between the inner and outer sealing portions. The inner sealing portion of the seal ring is longer than the outer sealing portion. The web is as thick as or thicker than the inner and outer sealing portions. The seal ring comprises inner and outer concentric hollow cylinders having a non-uniform wall thickness and an annular rib that connects the hollow cylinders together, where one cylinder is longer than the other and where the rib has a longitudinal thickness that is as great as the radial thickness of the walls of the hollow cylinders.

A unitary steel bracket has an arced portion and a hanger appendage extending perpendicularly from a convex perimeter of the arced portion. The arced portion has two opposed planar surfaces with parallel mount holes through each end. The hanger appendage has two opposed planar surfaces coplanar with the arced portion planar surfaces. A portion of the hanger appendage is bent at a 90-degree angle and has a support mount hole perpendicular to the parallel mount holes. the bracket is prefabricated to a predetermined bracket size corresponding to a predetermined pipe flange size. A method of hanging joined flanged includes providing the bracket; aligning the parallel mount holes with holes on a pipe flange; inserting connection bolts through the holes; threading nuts onto the bolts to a predetermined torque; and attaching the support mount hole to a building structure.

An adapter includes several connecting nozzles. Free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels. Moreover, the adapter includes a projection, which extends from the nozzle end with a length to a free projection end remote therefrom. A fluid line system formed by means of the adapter comprises, furthermore, a fluid line with, enveloped by a wall, a lumen. The fluid line can be connected with its line end to the connecting nozzle of the adapter in such a manner that the projection protrudes inwardly into the lumen of the fluid line to form two tubular chambers of the fluid line mutually separated by the projection and adapted for guiding through flowing fluid.
