摘要： A pipe connector includes a connecting structure configured to secure a first section of hose, pipe, or tube to an adjacent second section of hose, pipe, or tube positioned adjacent to the first section at a joint between the first section and the second section. The connecting structure includes at least one segment of a thermally adaptive material. The at least segment is configured to undergo a shape change as a result of thermal cycling such the shape change causes the connecting structure to form a leak-free seal between the first section and the second section at the joint.

摘要： A method of installing a 3-piece pipe coupling to connect a first pipe element to a second pipe element includes the steps of bringing the 3-piece pipe coupling into engagement with a first connection groove located proximate a first pipe element end of the first pipe element and with a second connection groove located proximate a second pipe element end of the second pipe element, the 3-piece pipe coupling comprising three pieces; and tightening the 3-piece pipe coupling about the first and second pipe element ends with a fastener extending through a first fastener pad and through a second fastener pad formed at respective distal ends of two pieces of the three pieces comprising the 3-piece pipe coupling.

摘要： A valve and coupling for joining pipe elements has a valve body captured in a central space defined by a plurality of coupling segments attached to one another end to end. The inner surface of the valve body defines a bore. A liner on the inner surface surrounds the bore and forms a seal with a valve closing member. Circumferentially arranged projections on the segments engage and center the valve body within the central space. The liner has lobes that extend axially in opposite directions. The lobes are compressed between the segments and the pipe elements to form a fluid tight seal when connection members are tightened to draw the segments toward the central space and into engagement with the pipe elements.

摘要： A pipe connection ring for a pipe coupling includes a ring body defining a first circumferential end and a second circumferential end opposite the first circumferential end; a first stepped portion extending from the first circumferential end of the ring body; and a second stepped portion extending from the second circumferential end of the ring body, the second stepped portion contacting and overlapping the first stepped portion in an uncompressed configuration; wherein the second stepped portion is unconnected to the first stepped portion and is configured to slide relative to the first stepped portion as the pipe connection ring is compressed.

摘要： A clamp connection for use with flowlines of a hydraulic fracturing operation has a female clamp hub having a seal pocket formed in the face thereof, a male clamp hub having a raised face at an end thereof, an elastomeric seal received in the seal pocket of the female clamp hub, and a clamp connector extending around the female clamp hub and the male clamp hub so as to maintain the male clamp hub and the female clamp hub in a liquid-tight relationship. The male clamp hub has an annular protrusion extending outwardly of the raised face. The annular protrusion bears against a side of the elastomeric seal. The raised face of the male clamp hub is received in an interior of the female clamp hub.

摘要： A three-way clamp includes a first clamp shell and a second clamp shell capable of being connected to or detached from each other. Each of the first clamp shell and the second clamp shell includes three engaging portions. The engaging portion includes an accommodating cavity. The two clamp shells are respectively provided with an engaging claw and an engaging groove. A connector prefabricated component including the clamp includes a connecting pipe fixed in the clamp body, wherein the accommodating cavity is provided with a sealing component for sleeving pipe opening. During construction, a straight pipe to be connected is inserted into the sealing component. Then the clamp body is tightened, and the sealing component tightly presses on a pipe body of the straight pipe to achieve sealing.

摘要： A water heating device equipped with a housing, a fan and a chamber arranged in the interior of the housing, and screws. The housing has first and second side plates which oppose one another in a first direction and extend from the ends of a back plate along a second direction intersecting the first direction. An opening part is provided in the housing on the side opposite the back plate in the second direction. The fan has a discharge opening, a first flow passage extending along the first direction, and a first flange. The chamber has an intake opening, a second flow passage extending along the first direction, and a second flange. The first and the second flanges are secured by screws. In a planar view, the center axis of the screws is slanted such that a head portion is closer to the opening part than the tip-end portion.

摘要： A clamping device suitable for securing a pair of flanges together is a unitary strip of a polymeric material that defines a multiplicity of clamping segments linked by flexible strip portions. The ends of the unitary strip define latching elements shaped to interconnect when the ends are brought together. Along one face of the unitary strip the clamping segments define teeth that project at opposite sides of the unitary strip, and these teeth define faces that are adapted in use to contact outer faces of the pair of flanges. Each clamping segments may define two opposing teeth. The clamping device can be operated with a single hand, being bent around the outside of the pair of flanges so that the clamping segments engage opposite faces of the pair of flanges and hold them together, and the latching elements are interconnected.
