A pipe connection fitting includes a gasket holder ring, a flap ring and a grip ring operably coupled together. A terminal housing is configured to engage with the gasket holder, flap ring and grip ring to form the pipe connection fitting adjacent an end of a pipe. The flap ring includes a plurality of tabs extending therefrom to provide an abutment for controlling a relative position of the grip ring.

A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange is of generally annular disc shape with an inner surface, an opposing outer surface, an inner edge, and a radially-spaced outer edge. Each pipe flange includes an annular outer recess formed on the outer surface adjacent to the inner edge. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. Each liner flange may be positioned within the outer recess of a successive one of the pipe flanges.

An embodiment includes a spool that may expand and contract to ease removal and addition of components to an oilfield manifold.

Flange for a hose (2), which flange comprises: an annular flange body (4) having a central hose opening (5); an annular locking element (9) for locking the annular flange body (4) in a circumferential groove (3) of a hose (2), which annular locking element (9) is composed out of at least two generally arc shaped locking element parts (9), wherein the annular locking element (9) is concentrically arranged in the central hose opening (5) of the annular flange body (4); and couplings (7, 8) for each of the at least two generally arc shaped locking element parts (9), wherein each coupling (7, 8) has a first coupling part (7) arranged on the annular flange body (4) and a second coupling part (8) arranged on the respective arc shaped locking element part (9), which first coupling part (7) couples to the second coupling part (8).

A telescoping fluid coupling (10,110) is provided for use with a fluid flow device (12) and includes a coupling body (14,114) having a fluid port (16,116) extending along a longitudinal axis (18,118). A retainer (20,120) is fixed to the body (14,114) and includes a retaining shoulder (26,126). A flange (22,122) is mounted to the fluid port (16,116) and includes a radially inwardly facing guide surface (36,136) that surrounds a mount surface (24,124) and extends longitudinally along the axis (18,118) to provide guided, sliding translation of the guide surface (36,136) relative to the mount surface (24,124) along the axis (18,118). The flange (22,122) further includes a stop shoulder (38,138) to engage the retaining shoulder (26,126) to limit the translation of the flange (22,122) along the axis (18,128).

A pipe connection device according to the present invention includes: a connection member including a projection in which an insertion space is formed in the projection and a pipe is inserted through one side and which is bent in a circumferential direction at the other side and a separation preventing unit which is spaced apart from the projection and protrudes in the circumferential direction; and a flange member coupled to the circumference of the connection member between the projection and the separation preventing unit so as to contact the projection and having a joining hole penetrated by a joining member.

An irrigation pipe and method of fabrication that utilizes a pipe that is made of a durable material, e.g., stainless steel or aluminum. During fabrication, the pipe is equipped with a plurality of components, i.e., a flange assembly, a truss mount, and an outlet, without drilling, welding, or the like. In this manner, a method of fabrication is provided that enables a plurality of components to be assembled to the pipe without compromising the integrity of the pipe material or treated surface so that galvanizing or painting is not required after the plurality of components have been fitted to the pipe.

A separation preventive pipe joint having an adjustable angle of deflection. A lock ring storage groove accommodates a metallic lock ring that can be engaged with a spigot protrusion and a cushioning material that comes into contact with a bottom of the lock ring storage groove and a side wall on a socket opening side. The cushioning material is made of a material softer than the lock ring.

An articulating coupling assembly for coupling a pipe end to a support structure, the assembly including: a pipe end fitting configured for fitting onto a free end of a pipe; a spherical bearing which is part of said pipe end fitting, the spherical bearing having a maximum diameter not greater than that of the pipe end fitting; a flanged collar configured to receive the pipe end fitting in a snug fit; a radially outer wall of the spherical bearing having one or more slots extending along the bearing in a direction parallel to the axial direction of said pipe; and a radially inner wall of the flanged collar having one or more radially inwardly protruding dogs proportioned to be received snugly in the one or more slots of the radially outer wall of the spherical bearing.

The invention includes a connector for coupling to a composite pipe, and methods for forming the same. The connector has a seal carrier forming a fluid passage that is made of a first material and that includes a seal receiving portion configured to receive at least one seal and a first coupling surface on an outer seal carrier surface. The connector also has an interconnect with a passage configured to receive the seal carrier that is made of a second material and includes a second coupling surface on an inner interconnect surface configured for coupling with the first coupling surface to connect the seal carrier and the interconnect and a third coupling surface on an outer interconnect surface.
