摘要： A joint ring system for lined pipes includes a first pipe and a second pipe joined end-to-end, each pipe having an interior lining covering substantially all of an interior wall of the respective pipe. A first ring is disposed within and substantially flush with the joined end of the first pipe, and a second ring is disposed within and substantially flush with the joined end of the second pipe. The first ring is configured to create a first circumferential pressure seal against the interior wall of the first pipe, and the second ring is configured to create a second circumferential pressure seal against the interior wall of the second pipe. At least one of the first ring and the second ring is configured to create a pipe joint pressure seal against the other ring.

摘要： A connection of two pipes each including a liner. Liner sections connected to the liners are sections joined together forming a joint of the liner sections. An electrofusion coupling may overlie the joint of the liner sections and be used to fuse the joint. A collar may be positioned to overlie the joint of the liner sections. A bushing may be positioned between the joint of the liner sections and the collar. Hubs may be connected to the ends of the pipes. The liner sections and hubs may include corresponding structure which resists movement of the liner sections away from the joint of the liner sections. A connection of two pipes each including a liner may be formed according to disclosed methods.

摘要： A connector for lined pipelines includes a tube having opposed male interface elements extending inwardly from respective ends of the tube. One or more circumferential permeable chokes project radially from each male interface element. The chokes minimise flow of oxidising fluid from the bore into the micro-annulus between the liner and the pipe while maximising flow of fluid from the micro-annulus into the bore in the event of catastrophic pressure drop in the bore. To maintain gaps between the tube ends and the pipe liners for fluid flow, shoulder formations defined by radially-projecting bands extend circumferentially around the tube. The connector may be used in a joint arrangement where each liner includes a body section, an end section of lesser thickness and greater bore than the body section that terminates short of an end of the pipe, an inner step disposed between the body section and the end section, and an outer step disposed between the end section and the pipe.
摘要翻译：用于内衬管道的连接器包括具有从管的相应端部向内延伸的相对的阳接口元件的管。一个或多个圆周可渗透的扼流器从每个阳接口元件径向突出。扼流圈使氧化流体从衬里和管道之间的微环空间中的流动最小化，同时在孔内存在灾难性的压降的情况下使流体从微环到最大的流量最大化。为了保持管端和用于流体流动的管道之间的间隙，由径向突出的带限定的肩部结构围绕管周向延伸。连接器可以以联接装置使用，其中每个衬套包括主体部分，具有较小的端部，其厚度小于比端部短的端部的主体部分具有更大的孔;内部台阶，其设置在主体部分和端部，以及设置在端部和管之间的外部台阶。

摘要： A conduit (100) comprising a plurality of conduit segments (112A–112C) each having a body (120A–120C) and a segment lining (136A–136C) made of a lining material. Each body includes a joint face (132A–132C) having secured thereto a portion (140A–140C) of the corresponding segment lining. A monolithic lining (108) is formed from the segment linings by abutting the conduit segments with one another so that the joint faces face one another and the portions of the segment linings contact one another. The portions of the lining on the joint faces are heated to a temperature above the melting point of the lining material so that they fuse with one another so as to form a fusion (148A, 148B) located between the joint faces.

摘要： A pipe liner connector suitable for connecting pipe sections that comprise a liner is described. The pipe liner connector comprise vents and/or venting grooves which act to balance the pressure between the micro-annulus, formed between the liner and the pipe sections, and the pipe bore formed when the pipe sections are connected together. The inclusion of these features helps prevent the collapse or the uncontrolled distortion of the pipe liner connector during pressure cycles in operating pipelines.

摘要： A welded joint for metal pipes provided with an inner lining, which is resistant to damages caused by the fluids flowing through them. The pipes are machined in the inside at the areas next to the ends to be joined, forming an undercut at each end. An spacer ring is inserted in the hollow annular space formed by both undercuts. The outer diameter of this spacer ring is substantially equal to the diameter of the corresponding undercuts, and its axial length is substantially equal or less than the sum of the axial lengths of the undercuts of the pipes to be joined. The spacer ring is made of an outer annular layer of a high thermal conductivity metal and at least one inner annular layer of heat-insulating and heat resistant material. The outer annular layer abuts in heat conducting contact with the metal pipes within said undercuts, and the metal pipes are joined by a weld seam.

摘要： Means for securing a polymer liner to the inner surface of a pipe comprises an end piece consisting of a hub portion and a corrosion resistant metallic insert. The polymer hub is fusion welded to the end of the liner, and the metallic insert is seal welded portion of the inner surface of the pipe clad with corrosion resistant material at a distance from the outer end of the pipe. The clad portion may be provided by a pup piece welded to the end of the pipe. This arrangement allows two lengths of lined pipes to be joined by welding with a continuous corrosion resistant internal surface, without damage to the polymer pipe linings and in a manner which allows an assembled pipe string to be spooled onto a reel for subsequent pipelaying operations. In the preferred embodiment, the metal insert is screw-threaded to the polymer hub with an elastomeric seal therebetween, which provides a secondary seal between the end piece and the pipe wall. An alternative means of terminating a polymer lining sleeve for other purposes, such as a flange-type joint, is also disclosed.
