Abstract: A pipe connector includes a pipe fitting including a passageway extending between upstream and downstream ends. An annular seat is formed within the passageway. A grommet includes a cylindrical portion and a conical portion extending from the cylindrical portion. A passageway extends through the cylindrical conical portions. With the grommet disposed within the passageway of the pipe fitting spaced from the upstream end, the cylindrical portion engages the annular seat and the conical portion extends along an inner wall of the pipe fitting between the annular seat and the downstream end. When an upstream pipe is received through the upstream end and along the passageway of the grommet, the conical portion compresses between and seals against the upstream pipe and the inner wall. With the downstream end of the pipe fitting connected to a downstream pipe, the pipe fitting and grommet fluidly connect the upstream pipe and the downstream pipe.

Abstract: A refrigerant pipe of a refrigeration apparatus includes: a first pipe, made of stainless steel, through which a refrigerant flows; a joint pipe, made of a material different from stainless steel, disposed on an outer peripheral surface of the first pipe; and a second pipe, having a diameter smaller than a diameter of the first pipe, connected to the outer peripheral surface of the first pipe via the joint pipe. A surface of the second pipe at which the second pipe is connected to the joint pipe is made of a material identical to the material of the joint pipe.

Abstract: A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.

Abstract: A connector includes a flow path extending in an axial direction along a central axis, a body including a through hole extending in the axial direction, a pipe including a through hole extending in the axial direction, and a seal including a sealing material between the body and the pipe. The body includes a body-side opposing surface opposing the pipe. The pipe includes a pipe-side opposing surface opposing the body. The seal is between the body-side opposing surface and the pipe-side opposing surface. The seal includes a reservoir in which the sealing material collects between the body-side opposing surface and the pipe-side opposing surface.

Abstract: The invention relates to a force generator for generating a linear pressure force, including a housing, an output wedge displaceably arranged in the housing, and a drive wedge for transmitting an externally exerted pressing force into a linear movement of the output wedge. The output wedge is connected to a first pressure element. The housing is connected to a second pressure element. A force applied to the drive wedge causes displacement of the first pressure element relative to the second pressure element. The force generator solves the technical problem of providing a high pressure force and using the known press jaws for this purpose.

Abstract: An apparatus for sealing a hole or a shape in a surface may be disclosed. According to an exemplary embodiment, a soft material may be provided containing an interior hole, an exterior surface, a top lip, and an outer area. In an exemplary embodiment, a bottom lip may be further incorporated. In another exemplary embodiment, a rough surface may be imprinted onto the pipe seal apparatus. The rough surface may be imprinted into the interior portion of the body and the exterior portion of the body and the top lip, or both. An adhesive pipe sealant may be used along the rough surface. The rough surface may have a higher overall surface area for the adhesive to bond to, creating a stronger bond and preventing delamination.

Abstract: A fitting for connecting a branch conduit to a liner installed in a main pipe is configured to mechanically connect to the branch conduit as it is inserted into the branch conduit from inside the main pipe. The mechanical connection is established without rotating the fitting. The fitting can include a body having an outer shaft section for being received in the branch conduit and an inner flange section for opposing the liner within the main pipe. The fastener include one or more teeth that extend radially from the exterior of the shaft section. The teeth can be secured to the shaft section by deforming portions of the fitting body against the teeth. The flange section supports a gasket for sealing against the liner when the fitting is installed. The flange section can include a rim that maintains the gasket in the proper position.

Abstract: A pipe fitting having a base configured to engage with a pipe, the base having a mounting seat configured to engage directly with the pipe, a base ring configured to engage with the mounting seat, and a base flange configured to engage with the base ring, a top hat configured to engage with the base, the top hat having a top cap, a top hat ring configured to engage with the top cap, and a top hat flange configured to engage with the top hat ring, wherein the top hat flange is further configured to engage with the base flange to form a fitting cavity. A pipe flow controller may be in fluid communication with the internal pipe volume through a threaded nipple, while also being securely housed within the fitting cavity, thus protecting the pipe flow controller from corrosion, impacts and other forms of damage to prevent leakage.

Abstract: A spud connection to a cylindrical tank wall includes a spud body welded to a cylindrical tank wall. In at least some embodiments, the spud body has an arcuate and concave first end surface, and a planar second end surface spaced apart from the first end surface. A weld joint between the first end surface of the spud body and an outer surface of the cylindrical tank wall surrounds an aperture that extends through the cylindrical tank wall, so that a leak-free fluid connection to an interior volume of the tank can be achieved.
