A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides a restrained pipe joint including a first pipe including a bell with a spigot entryway and a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of restraining segments is at least partially embedded in the gasket, each restraining segment including a toothed inner face and a smooth, sliding front radial face arranged to slide against the front radial wall of the annular groove and facilitate wedging of the segment between the plastic pipes.

A press apparatus includes a press assembly and an activation assembly. The press assembly includes a plurality of dies. The plurality of dies defines a center opening for receiving a work piece. The central opening defines a central longitudinal axis. The activation assembly is adapted to actuate the press assembly. The activation assembly includes a first switch and a second switch. The second switch includes a capacitive touch surface that faces in a direction toward the central longitudinal axis of the press assembly.

A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.

An apparatus and method for crimping coupling rings are provided. The apparatus generally has a lower clamp head and an upper clamp head that may be drawn together by a fastener. The lower and upper clamp heads are designed to receive a first portion and a second portion of a coupling ring, respectively. A first and second post holds the clamp heads adjacent to each other. The upper clamp head is secured to the first post such that the upper clamp head may rotate in a generally circular motion to switch the apparatus from a closed to an open configuration, or vice versa. When the apparatus is placed in a closed configuration, the fastener may be engaged to draw the clamp heads together to increase the compressive force imposed on a coupling ring until the coupling ring becomes crimped.

A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.

A pressing tool for joining a pipe and a fitting, including two swivel elements for pressing the pipe and the fitting, a receiving region, formed between the swivel elements, for receiving the pipe and the fitting, at least one swivel axis for rotatably mounting the swivel elements, and a tensioning mechanism for pretensioning the pressing tool. The swivel elements can be swivelled towards one another about the at least one swivel axis to press the pipe and the fitting. In a first, closed position, the receiving region is narrower than in a second, open position, of the swivel elements, wherein the swivel elements are pretensioned towards the closed position by the tensioning mechanism. At least one holding device is provided for holding the swivel elements in the open position against the pretensioning force generated by the tensioning mechanism.

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.

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.

An inner roller used for roll forming pipe elements has a flange extending radially from a body. The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming.

A method of manufacturing a joint flange using a thickness-increased, machined pipe is provided. The method includes a pipe cutting operation in which a pipe is cut to a predetermined length, a flange forming operation in which a flange having a mounting hole for installing the pipe is formed by die casting, a bump-forming operation in which a thickness-increased part, which is formed by increasing a thickness of one end of the pipe, is bumped to form a first bead locked to the flange, a machining operation in which a circumference of the thickness-increased part is machined to form a sealing groove having an O-ring installed, and a fixing operation in which the pipe is inserted in the mounting hole of the flange and the other end of the pipe is pressed to form a second bead so that the pipe is pressed to a lower end of the flange.
