A duct system for an air intake system for a vehicle, the duct system including a first duct having a first duct wall that defines a first duct opening and forms a conduit configured for conveying fluid through the first duct opening in an axial direction of the first duct opening, and a rim fixed with the first duct wall and extending from the first duct in the axial direction of the first duct opening, and disposed around the first duct opening, with a first rim portion and a second rim portion disposed along opposite sides of the first duct opening in a lateral direction of the first duct opening perpendicular to the axial direction of the first duct opening. The duct system also includes a second duct including a second duct wall that defines a second duct opening in fluid communication with the first duct opening.

The techniques introduced here include a system and method for efficiently connecting two or more pipes through the combination of a pushing plate, a gasket and a sealing plate. Such techniques exploit the presence of concentric protuberances, or rings, on the sealing plate that help, also thanks to the space between them, in keeping the cleanness, tightness and flexibility of the conjunction, especially when sticky substances, like a sludge, are dealt with.

In some implementations, an apparatus comprises a pipe, a stud that is forge-welded to the pipe, creating a forge-welded stud, a bracket that is operably coupled to the forge-welded stud, and a ladder support operably coupled to the bracket.

An industrial process field device includes a pressure sensor, and a housing containing the pressure sensor. The housing includes a base having a base interface and a first base process opening. A flange is attached to the base and includes a flange interface having a first flange process opening. A first gasket process opening of a gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket engages the flange interface. A dielectric insulation system includes at least one dielectric layer that insulates the housing from electrical currents conducted through the flange. Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold, which improve a maximum working pressure of the field device.

A coupling system, in particular for tubular elements, with a socket element and a plug-in element, wherein a locking element is also provided, wherein the socket element has a tube-like receiving region for receiving the plug-in element, wherein the locking element has a securing element which is supported in the plugging-in direction against a securing mating element of the plug-in element and the locking element is supported with a locking device against a locking mating device on the socket element, and therefore the socket element and the plug-in element are secured axially indirectly via the locking element and thus via the securing element, the securing mating element and the locking device and the locking mating device.
