A system (10; 110; 210; 510) for identifying a pipe and/or associated component parts of a piping system, comprises a vibration generation arrangement (12, 112, 212, 312, 512) configured for engagement with, for coupling to and/or operatively associated with a first pipe section (P1) and a vibration detection arrangement (14; 514) configured for engagement with, for coupling to and/or operatively associated with a second pipe section (P2; P3; P4). The vibration generation arrangement (12, 112, 212, 312, 512) is configured to generate a vibration in the first pipe section (P1), which forms an identification signal propagating along the pipe. The vibration detection arrangement (14; 514) is configured to detect vibration in the second pipe section (P2; P3; P4) and thus identify whether the second pipe section (P2; P3; P4) and the first pipe section (P1) form part of the same pipe or pipe assembly.

A press fitting for a pipe connection is provided. The press fitting includes a fitting body for connecting the press fitting to a pipe, a press sleeve fixed to the fitting body and having a substantially cylindrical pressing portion and at least one projecting element which delimits the substantially cylindrical pressing portion in the axial direction, and a tubular banderole which surrounds the substantially cylindrical pressing region of the pressing sleeve, wherein the tubular banderole is arranged rotatably relative to a surface of the pressing sleeve, is held in the cylindrical pressing region by the at least one projecting element and is at least partially destroyed when the pressing sleeve is pressed with a pressing tool.

An encapsulated tubular cable with a colorized identification strap includes armored protection ducts and an encapsulation protection layer. A hollow passage is formed in the center of the duct body after each armored protection duct is formed. A wire cable, an optical fiber, or an oil duct is placed in the hollow passage. The encapsulation protection layer wraps the armored protection ducts. A plurality of armored protection ducts are arranged in one encapsulated protection layer. A peripheral edge of each armored protection duct is correspondingly provided with at least one colorized identification strap group. The encapsulation protection layer improves the corrosion resistance of the encapsulated duct cable; the colorized identification straps are provided at the thinnest positions of the encapsulation protection layer to facilitate tearing and encapsulation; and each colorized identification strap has a respective color identifier, which is convenient for distinguishing objects in each hollow passage during use.

This disclosure relates to a quick connector adapted to display a code that verifies that a latch member is engaged to retain an installed pipe to the quick connector. The quick connector comprises a connector body having a receiving portion surrounding an internal passage, the internal passage arranged to receive the pipe therein. A latch member retained on the receiving portion is arranged to be movable between a pipe insertion position and a latched position. In the pipe insertion position, the latch member allows the pipe to be inserted into the internal passage. A code readable by a scanning device becomes readable when the latch member is moved to the latched position verifying that the pipe is installed and latched in the connector body.

The disclosure relates to a plug connector and method for connecting pipes for liquid or gaseous media. The plug connector includes a connector body and a locking element. An indicator element is formed, which has an indicator surface, a first partial section and a second partial section, wherein the first partial section and the second partial section are flexibly coupled to one another by means of a spring section. The first partial section is connected to the locking element, and the indicator surface is formed on the second partial section, wherein the indicator element is formed such that, in a locking position of the locking element, the second partial section is deformed relative to the first partial section, so that the indicator surface is pushed into an indicator position.

A coupling system having an inner tube, a collar, a circular gasket concentrically disposed between the inner tube and the collar; a pair of CAM levers structurally engageable with the collar, and a handle connecting the pair of CAM levers such that a user can single-handedly move the handle between the locked position and the unlocked position.

An encapsulated tubular cable with a colorized identification strap includes armored protection ducts and an encapsulation protection layer. A hollow passage is formed in the center of the duct body after each armored protection duct is formed. A wire cable, an optical fiber, or an oil duct is placed in the hollow passage. The encapsulation protection layer wraps the armored protection ducts. A plurality of armored protection ducts are arranged in one encapsulated protection layer. A peripheral edge of each armored protection duct is correspondingly provided with at least one colorized identification strap group. The encapsulation protection layer improves the corrosion resistance of the encapsulated duct cable; the colorized identification straps are provided at the thinnest positions of the encapsulation protection layer to facilitate tearing and encapsulation; and each colorized identification strap has a respective color identifier, which is convenient for distinguishing objects in each hollow passage during use.

A method for producing a tube arrangement for the transport of tempering medium, in which base body sections are provided, which have congruently configured separating surfaces, wherein at least one functional element on at least one base body section is arranged in such a way that it can be in contact with the tempering medium, whereafter the base body sections are joined along the separating surface and bonded to one another to form the tube arrangement.

A system of visual and non-visual marks for pipes and couplings which allows users to group the pipes and couplings by type, size, end configurations and composition with a series of symbols, including colors, shapes, swirls, patterns. The symbols are applied to the pipes and couplings by printing, etching, painting, applying stickers, and or molding. The non-visual mark utilize the magnetic and radio reflective nature of the marks to allow remote identification of the plumbing pipes and couplings after being buried.

A male element (10) for a fluid connection comprises a male body (12) comprising a tubular extension (20) and a crown (22) fixed around the tubular extension and having at least one radial recess opening onto an inner face (44) and onto an outer face of the crown (22). The male element comprises an integral ring (16) mounted around the crown, and for each radial recess, a locking element (14), movable between an inner position and an outer position, the outward movement of which is limited by the ring. Each radial recess is delimited by an inner wall (52) forming part of the crown and extending around a radial central axis of the radial recess. The ring has at least one longitudinal slot, which passes radially through the ring, and comprises a resiliently deformable end portion (112). A free end of the end portion comprises at least one inner tooth which is engaged in an outer groove, recessed in the crown.
