Embodiments of the present disclosure provide an axial swage tool configured to axially swage a fitting to a tube, a cable, or other such item of manufacture. The swage tool can be configured to utilize swaging engagement members for grasping and driving a swaging ring over a fitting. The swaging ring thereby radially compresses the fitting around the tube or other item.

Provided are: a joining structure capable of suitably obtaining joining strength between components which compose the joining structure; and a joining method thereof. For this purpose, a joining structure (1) includes: a shaft member (10); and a thin-walled cylindrical member (20) that fits an inner circumferential surface thereof to an outer circumferential surface of the shaft member (10). The thin-walled cylindrical member (20) has: a first crimped portion (21), in which an axially intermediate portion is reduced in diameter in a radial direction, and is crimped to the shaft member (10); and a second crimped portion (22), in which an end surface (20a) is folded radially inward, and is crimped to the shaft member (10).

A pipeline system is enclosed including unlined or plastic lined pipes. A mechanical metal to metal connection is employed that can provide a fluid tight seal. A pipe coupling may be employed to span the connection. Plastic lined pipes can have their plastic liners connected to form a fluid tight bladder. Electro fusion may be employed.

A sealed sleeve installed at an insertion coupling portion in a state in which a first pipe and a second pipe are insertion coupled to each other in order to seal couple the first pipe having a first outer diameter and a first inner diameter and the second pipe having a second outer diameter and a second inner diameter larger than the first outer diameter includes: a pillar shaped-main body having a main body central shaft; a through-hole formed using the main body central shaft as a central shaft on the main body and having an inlet as a second pipe side opening in an installation state and an outlet as a first pipe side opening in an installation state, wherein in the through-hole, a pressing portion that applies a sealing pressure to the insertion coupling portion is formed in a portion of an inner wall, and an inner diameter of the pressing portion is smaller than the second outer diameter.

A pipe connection apparatus may include an outer body having a pipe mount part having a pipe insertion space opened rearward so that a pipe end is inserted into the pipe insertion space, and a swaging ring configured to come into contact with and press at least a part of the pipe mount part while surrounding at least a part of the pipe mount part.

A pipe manipulation apparatus having a base frame and a sliding end slidable towards and away from the base frame, each of the base frame and sliding end having at least one pipe support coupled with a press clamp pivotable between an open position and a closed position, wherein in the open position, a pipe is placeable on to the at least one pipe support and, in the closed position, the inner surfaces of the press clamp and the pipe support define a bore in which a lengthwise portion of the pipe is receivable. The pipe manipulation apparatus may be portable, tiltable, and/or rotatable to accommodate pipes of various locations and angles.

Embodiments of the present disclosure provide an axial swage tool configured to axially swage a fitting to a tube, a cable, or other such item of manufacture. The swage tool can be configured to utilize swaging engagement members for grasping and driving a swaging ring over a fitting. The swaging ring thereby radially compresses the fitting around the tube or other item.

The invention relates to a coupling which includes at least: a tubular coupling member suitable for receiving a pipe and comprising one or more annular ribs, and a crimping ring arranged on the coupling member and translatably movable between a position for inserting the pipe into the coupling member, and a crimping position, in which the crimping ring immobilizes the pipe relative to the coupling member after the deformation of the one or more ribs. Recesses are formed between the coupling member and the pipe in the crimping position. The coupling has at least one exhaust opening arranged such as to provide fluid communication between said at least one recess and the outside of the coupling.

A system having a device for producing a pipeline unit from a pipeline having a pipeline outer surface and a pipe connector having a pipe connector outer surface. Also described is a method for producing the system.

A joining structure airtightly or liquid-tightly joins an outer peripheral surface of the pipe member and an inner peripheral surface of a cylindrical member to be mounted on the pipe member, and the pipe member and the cylindrical member are made inseparable by an annular protrusion formed on the inner peripheral surface of the cylindrical member.
