A flanged sealing ring which is used to seal a pipe connection is produced from a material having a metal fraction distributed substantially homogeneously in the flanged sealing ring. The flanged sealing ring can be used in a device for detecting components of a flanged sealing ring in a pipeline system that includes a plurality of pipes, at least two of which are held against each other at a flange in such a way that sealing is effected by a flanged sealing ring. Using a metal detector and a gate for removing a metal-containing substance from the pipeline, which gate is arranged behind the metal detector in the conveying direction, the flanged sealing ring can then be detected, and therefore, when components of the flanged sealing ring detach, detection can be performed at the metal detector and discharging can be performed at the gate.

A sealing assembly for flanges is described. The sealing assembly includes a wedge, a first sealing element, a second sealing element, and a fastener. The wedge has a first surface, a second surface, and a third surface. The first surface defines a pressure void with a first flange and a second flange. The first sealing element engages the second surface of the wedge and the first flange. The second sealing element engages the third surface of the wedge and the second flange. The fastener couples the first sealing element, the first flange, the second flange, and the second sealing element together. The wedge slides toward the sealing elements responsive to a pressure increase in the pressure void. The sealing elements force the flanges toward each other responsive to the wedge sliding toward the first sealing element and the second sealing element.

A connector element comprising a body, a locking mechanism and a seal. The seal comprises a base arranged facing, backward to a proximal surface and facing, forward to a distal surface of the body, as well as a lip. The lip extends parallel to a longitudinal axis of the body and forward, protruding from the base and defining a free front edge. The seal presents a peripheral notch that is arranged, radially to the longitudinal axis, between the base and the lip, which opens to the front of the seal and a bottom of which is delimited on the rear by a joining portion of the seal connecting the base and the lip. The seal is configured to press backward against the proximal surface, in alignment with the free front edge of the lip, according to a direction parallel to the longitudinal axis.

A pipe fitting system, including a first pipe section with at least one male end, a second pipe section with at least one female end, and a connecting means for releasably connecting the pipe sections together such that the male end is at least partially received within the female end. The connecting means comprising releasably engageable first and second connectors associated with the first and second pipe sections respectively, wherein the first connector comprises at least one outwardly extending protrusion and wherein the second connector comprises corresponding recesses adapted to releasable receive the or each protrusion of the first connector. The pipe fitting system is suitable for applications such as end of line connections, repair/replacement of fixed existing pipes, and in enabling temporary removal of pipes for maintenance or access purposes.

A pipe coupler having a function of covering a pipe. The pipe coupler includes a coupler main body having a hollow, a grip ring provided in the hollow and configured to fix the pipe so as to allow the pipe to be inserted thereinto and prevent the inserted pipe from coming out, and a packing member provided in the hollow, and configured to seal a gap between the coupler main body and the pipe when the pipe is inserted into the packing member. The packing member includes a pipe locking protrusion protruding inward from an inner surface of a lower end portion thereof so that a front end portion of the pipe inserted into the packing member is surrounded and covered. The pipe coupler can prevent a coating layer of a pipe from being peeled from a tip of the pipe.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

In one example, a hygienic fitting assembly is disclosed. The hygienic fitting assembly includes a first fitting member defining an exterior opening, an interior opening, and a passage extending therebetween. The hygienic fitting assembly further includes a second fitting member receivable by the first fitting member with the first and second fitting members configured for removable mechanical attachment with one another along an interface region within the passage. The hygienic fitting assembly further includes a seal formed from a compression controlled and self-lubricating material. The seal is configured to receive an annular feature of one of the first or second fitting members and define sanitary fitting connection therebetween. The sanitary fitting connection is operable to prevent fluid escape toward the interface region during flow of a product between the first and second fitting members.
