A steel ring includes a locking component. The locking component is provided on an inner surface of a ring body in a protruding manner. The locking component includes locking teeth, and the locking tooth is sheet-like and includes a fixed part and a contact part. Multiple locking teeth constitute a first locking tooth group, and with regard to the locking teeth in the first locking tooth group, the distance between the fixed parts is smaller than the distance between the contact parts. Multiple locking teeth constitute a second locking tooth group, and with regard to the locking teeth in the second locking tooth group, the distance between the fixed parts is greater than the distance between the contact parts. The ring body has a first state and a second state. When the ring body is in the first state, the ring body is in an unclosed annular shape, and when the ring body is in the second state, the ring body is in a closed annular shape.

A support ring for a tubular connection is provided that comprises a body comprising a first end and a second end. A circumferential ring lip extends from the first end of the body and positioned perpendicular to the body. A protrusion is positioned on the body between the first end and the second end. The protrusion comprises a top surface and a bottom surface.

The present invention provides a press-fitting pipe connector with a toothed ring, including a pipe joint, a sealing ring, a toothed clamping ring, a bushing and a pipe. The pipe joint is a “-”-like round pipe with equal wall thickness, the sealing ring, the toothed clamping ring, and the bushing are assembled in an inner cavity of the pipe joint, a fitting end of the pipe joint is run through inner cavities of the bushing, the toothed clamping ring and the sealing ring in sequence, a radial pressure is applied using a press-fitting tool along an outer diameter of the pipe joint, and both ends of the pipe joint are squeezed from a pipe shape into a neck shape under the action of the pressure. Therefore, the strength index and the safety requirements of the gas, fire-fighting and heat supply pipes of the high-rise buildings can be satisfied.

A press fitting for an electrical conduit includes a fitting body and a press connector in a press-connection section of the fitting body to allow press-fit connection to a conduit. A conduit retainer in a conduit retainer section of the fitting body releasably grips and removably retains the electrical conduit in the fitting body before the press-connection section is deformed radially inward during the press connection process.

A press connection system comprises a press tool (50, 60), a fitting (1) and at least a first tube (2) of a first tube diameter (R13), the press tool (50) to act with force on a deformation zone (3) of the fitting (1). The deformation zone (3) is pressed either on first tube (2) of a first tube diameter (R13) or to a second tube (2) of a second tube diameter (R23), the second tube diameter (R23) being smaller than the first tube diameter (R13). Further, a press tool, inserts therefore and a tubing system and the use of these enable to connect tubes of more than one diameter to the fitting.

An assembly having a fitting body, a structure, an annular cavity within the fitting body, a grip ring, a seal element, and a spacing element. The structure has an end that is received in the fitting body. The annular cavity is disposed within the fitting body between an interior surface of the fitting body and an exterior surface of the structure. The grip ring, seal element, and spacing element are disposed in the annular cavity in a side-by-side relationship. The grip ring includes a plurality of first teeth that engage the exterior surface of the structure. Both the seal element and the spacing element extend radially across a height of the annular cavity such that the seal element and the spacing element each contact and sealingly engage the exterior surface of the structure and the interior surface of the fitting body.

Techniques for implementing a pipeline system including a pipe fitting, which includes a fitting shell that define a fitting bore and a tubing cavity around the fitting bore. The tubing cavity interfaces with pipe segment tubing to facilitate fluidly coupling the fitting bore to a pipe bore. The fitting shell includes a seal groove that is recessed into a fitting shell surface that facilitates defining the tubing cavity. The pipe fitting includes a belt seal having a multisided axial cross-section profile, in which the belt seal is to be disposed in the seal groove to implement a fitting seal in the pipe fitting that includes a protruding portion having a wedge-shaped axial cross-section profile that protrudes beyond the fitting shell surface into the tubing cavity to facilitate sealing a fluid conduit implemented in an annulus of the pipe segment tubing in the tubing cavity of the pipe fitting.

A metallic pipe connection may comprise a tubular body and a terminal tubular engagement portion configured to be engaged on a pipe and to be fixed thereto by means of plastic deformation of the engagement portion, and a terminal flange on the opposite side of the tubular body with respect to that one provided with the tubular engagement portion. The tubular engagement portion may include an annular seat for a sealing gasket, having a first housing groove for the sealing gasket which may be internally open towards the tubular engagement portion, and at least part of the tubular engagement portion and the annular seat may be plastically deformed such to generate a mechanical seal on the pipe on which the tubular engagement portion is fitted.

Provided are connector assemblies for connecting pipes. For example, a connector assembly can include a connector formed with a hollow into which a pipe is inserted. A large diameter portion on at least one side of both end portions of the hollow where the large diameter portion is formed has a relatively large inner diameter and a housing space inside. The connector assembly also includes a ring-shaped sealing member provided in the hosing space and a grip member provided adjacent to the sealing member in the housing space. Further, the grip member has a body portion formed to contact an inner circumferential surface of the large diameter portion and a pair of sharp portions formed to be bent from both sides of the body portion and to partially bite into the outer circumferential surface of the pipe by crimping the outer circumferential surface of the large diameter portion.

A fitting (3, 3′) for connecting to a tubular element (5, 5′) having a first end section (9, 9′) comprising at least one first connection element (21, 21′), wherein the diameter of at least a part of the first connection element (21, 21′) can be reduced in a radial direction in order to produce a connection, wherein the first connection element (21, 21′) comprises at least one first hook element (21, 21′) and/or at least one first crimp (237, 437) configured to be connected in force-fit and/or form-fit manner to at least one second crimp (7, 7′) and/or at least one second hook element (235) formed on the outer surface of the tubular element, when the diameter of at least a part of the first connection element (21, 21′) is reduced, as well as a tubing connection and a method for connecting a fitting to a tubular element.
