Pipe joint, which comprises at least one first pipe section (2), and a sleeve part 5, into which the butt end part of the pipe section (2) is disposed in such a way that the sleeve part (5) extends a distance on top of the pipe section (2) from the butt end of the pipe section that is inside the sleeve, and heating means (7), such as resistance wires. For forming the joint, a joint component (3) is arranged between the outer surface (16) of at least one pipe section (2) and the inside surface (15) of the sleeve part (5), which joint component is configured to form a joint with the sleeve part (5) when the joint area is warmed with the heating means (7), and that a collar (6) is arranged on the pipe section (2), which collar comprises a detent surface (10) for the joint component (3). The invention also relates to a method for forming a pipe joint.

The present invention concerns the technological field of tubes, tubes joint or tube accessories, more particularly, processes for joining tubes and channels. Problem to be solved: Among the main methods currently used for joining tubes, especially at a compressor terminal, it is cited brazing, which requires the use of high cost materials, presents high energy costs, in addition to having high rework rates. Problem solving : Herein is disclosed a process for joining tubes, preferably applied in discharge tubes of a compressor terminal, which provides joining of these by means of mechanical crimping and sealing of the joint by means of adhesive, without the need for welding, expensive bonding alloys, yet meeting the requirements of reliability, tightness and safety for joining these tubes.
摘要:
A sealing method, comprising: introducing a moving stream of curable material into an opening; and curing a portion of the moving stream of curable material flowing back out of the opening to form a cured layer of curable material. The cured layer restricts or prevents at least a further portion of the curable material from flowing back out of the opening.

A method and apparatus for securely joining a sleeve (10) to an end portion of a pipe (20). The method comprises positioning at least a portion of a sleeve (10) over an end portion of a pipe (20) to form an annular space (21) between the outer surface of the pipe (20) and the inner surface of the sleeve (10), inserting grout into the annular space (21) and allowing the grout to cure to secure the sleeve (10) to the end portion of the pipe (20).
摘要:
The invention relates to a method and equipment for producing pipe-couplings and a pipe-coupling with improved sealing made this way, with the help of said improved sealing of junctions of plastic pressure pipes (8) and plastic fitting bodies (1) is ensured by a closing flange (4) produced by a manual injection molding machine and where a cohesive bond is formed between the plastic pressure pipe (8) and the plastic fitting body (1) for ensuring closing. The invention relates to a method for a pipe-coupling with improved sealing, when a fitting (1) is housed in an end of a pipe (8) and a unit compiled this way is provided with a leak-proof closing. The method is characterized by that, after joining a pipe (8) and a fitting body (1), a junction formed this way is closed round by a sealing ring (4) made insite by injection molding.

A sprinkler assembly includes a sprinkler body and a tubular connection fitting. The tubular connection fitting includes a first end for connection to a fluid supply pipe and a second end with the sprinkler body inserted therein, the tubular member including an outer surface and an inner surface defining an internal conduit extending along a longitudinal axis, the inner surface of the tubular member includes a first stop surface spaced from the first end to define an insertion depth for the fluid supply pipe and a second stop surface to limit insertion of the sprinkler body into the second end. The first stop surface defines an annular channel for housing an end of the fluid supply pipe.
摘要:
A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.
