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.

The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange includes an inner surface and an opposing outer surface with a plurality of circumferentially spaced plateaus positioned thereon. Each plateau has a height above the outer surface. 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. The first and second pipe flanges may couple to one another such that each plateau on the first pipe flange contacts a corresponding plateau on the second pipe flange.

A method of joining a tubular member and a pipeline configured to convey corrosive products comprises preparing a tubular member with an inner seat; inserting the end of a pipeline inside the inner seat; inserting a sleeve of corrosion-resistant material inside the end of the pipeline; inserting an expandable mandrel inside the sleeve; and expanding the expandable mandrel to join the end of the pipeline and the tubular member, and seal the sleeve and the pipeline to protect parts of the pipeline, sensitive to corrosive products, via the sleeve.

A flange tab system includes a first member having a first-member-first-portion and a first-member-second-portion, a second member having a second-member-first portion and a second-member-second-portion, a third member, and a ring-like member. The flange tab system provides an electrical fitting for electrical current flow between pipelines or other structures. The flange tab system is configured to secure a wire to a pipeline for cathodic protection and various other applications.

An arrangement for fluid-tight connecting of lines including a first and second connection element. The connection elements are aligned with each other and are connected by fastening means. The arrangement includes an intermediate element between the connection elements and a holding element and a second sealing element. A first sealing element is arranged in the holding element between the sealing surfaces of the connection elements. The holding element has a hollow wall with a first and second edge. The second sealing element is connected to the holding element on the second edge. The intermediate element includes an indentation extending from a first end formed on an outer side of the second sealing element to a second end formed near the first sealing element. The first end has a conical shape, wherein oppositely arranged side walls of the indentation rest on one another on the outer side of the sealing element.

A full-face flare joint for a lined piping system having a connector portion of a metal piping being flared radially outwardly at a predetermined angle to form a pipe lap with a first surface and a second surface. The first surface is configured to engage a pipe flange. Further, a pipe lining extends out of the connector portion and is flared radially outwardly over the second surface of the pipe lap thereby forming a liner flare. A full-face flare component with a bottom portion is attached to the liner flare so that the bottom portion of the component forms an angle of about 90 with an inner surface of the pipe lining.

A pipe liner for lining a fluid-carrying pipe, the pipe liner comprising an elongated flexible conduit and a flexible flange. The flexible conduit includes an outer wall forming an open-ended central channel for allowing fluids to be pumped therethrough. The flexible flange extends radially from one end of the elongated conduit and includes a number of fastener holes. The flexible conduit and the flexible flange are configured to be collapsed and pulled through the pipe such that the flexible flange can be connected to a rigid flange of the pipe via the fastener holes. The pipe liner is less prone to leak and is easier to transport and install.

A connector for a pipeline, in particular for conveying hydrocarbons, extends along a longitudinal axis and has a gripping portion configured to be fitted around and clamped to the outer face; a sleeve portion, which is mounted in sliding manner to the gripping portion; a metal front gasket configured to be placed between the front end face and a face of the sleeve portion; and linear actuators connected with the gripping portion and the sleeve portion to axially compress the metal front gasket between the front end face of the pipeline and the face of the sleeve portion.

A gasket in a transport refrigeration system (TRS) and method of preventing corrosion in a compressor using a gasket. The gasket includes a body, where the body includes a fluid pass portion, and a flange that extends from the body. The body and the flange include a second layer between an outside first layer and a third layer. The second layer is a metal and the metal is a non-uniform thickness that extends across the flange and the body to deflect compression load distribution.
