The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.

There is described a pipe connector for connecting first and second pipes slidably engageable one into the other, the pipe connector comprising: a side wall extending between a first end and a second end along a longitudinal axis and defining an interior space, the side wall being adapted to be inserted into a floor hole made into a floor; a floor flange extending laterally and outwardly from the first end of the side wall, the floor flange being adapted to rest on a floor surface when the side wall is inserted into the floor hole; and a guiding assembly secured to the side wall and comprising at least one resilient retaining finger for receiving the first pipe therebetween, the at least one resilient retaining finger being securable to the first pipe when the second pipe is engaged into the first pipe.

An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.

A pipeline telescopic joint configured to compensate for dimensional changes has: a first pipe section having a first diameter; a second pipe section having a second diameter smaller than the first diameter is slidingly coupled to the first pipe section; an end assembly, which is fixed to the second pipe section an annular seat bounded by two facing cylindrical faces; and an annular gasket, which is housed within the annular seat and has a polymeric casing and a spring housed within the polymeric casing, wherein the polymeric casing is in contact with the cylindrical faces.

An expandable pipe spool operable to connect components of a hydrocarbon extraction assembly is provided. The expandable pipe spool includes a female pipe segment having an outer surface and an inner surface having at least one sealing groove; at least one fluid port on the outer surface of the female pipe segment for receiving a hydraulic fluid, the fluid port in fluid communication with the sealing grove; a male pipe segment having an outer surface receivable within the female pipe segment; a sealing member positioned within the sealing groove between the inner surface of the female pipe segment and the outer surface of the male pipe segment; and a fastening arrangement to lock the male pipe segment in a selected longitudinal position with respect to the female pipe segment.

Disclosed are embodiments of a coupling mechanism that can be used to selectively secure two sections of telescopically engaged pipe in a fixed position relative to each other and provide a fluid (e.g., gas and/or liquid) seal between to the coupling mechanism and the two pipes, regardless of whether the pipes are secured in the fixed position or are freely moveable relative to each other. In some embodiments, the coupling mechanism can be used as part of a faucet assembly, which can include an adjustable faucet assembly including the telescopically engaged pipe.
