A gland assembly includes a gland defining an annular ring, the annular ring defining a first gland end and a second gland end disposed opposite from the first gland end; and a gasket, the gasket defining a first gasket end and a second gasket end, the first gasket end disposed opposite from the second gasket end, a gasket bore extending through the gasket from the first gasket end to the second gasket end, a gland collar defined at the first gasket end, the gasket bore receiving the second gland end of the annular ring.

A block fitting for connecting components in a vehicular refrigeration system includes male and female blocks defining aligned bores that provide fluid communication between the assembled blocks. A primary seal member is disposed between the blocks in fluid tight relation. A separate secondary seal member spaced from the primary seal member is provided between the blocks. The seal members are pre-assembled onto one of the blocks to form a pre-assembled sub-assembly. In one form, the primary seal member is retained on the block by a polymeric guide ring.

A cooling pipe joint which enables easy fine adjustment of the length of a cooling pipe which extends from the cooling pipe joint. The cooling pipe joint is provided with a base part, a fastening member which is fastened to the base part, a deforming member which is arranged between the base part and the fastening member, and a first slanted surface which slants with respect to a center axis. This first slanted surface presses against the deforming member by the force of fastening the fastening member to the base part and makes the deforming member deform to a direction approaching the center axis.

An embodiment includes a spool that may expand and contract to ease removal and addition of components to an oilfield manifold. The spool may comprise: a first conduit to couple to a first flange via a first ring joint gasket; a second conduit to couple to a second flange via a second ring joint gasket, the second conduit including threads; a third conduit coupled to the first and second conduits; and a fourth conduit including threads, the threads of the fourth conduit directly engaging the threads of the second conduit. The first, second, and third conduits collectively form a channel that couples first and second opposing ends of the spool to one another and which includes a long axis. Rotating the fourth conduit about the long axis moves the second conduit linearly along the long axis.

A method of using a mechanical joint restraint includes inserting an end of a pipe length into a gland bore of a gland, a ring bore of a gripping ring, and a gasket bore of a gasket, the gland, the gripping ring, and the gasket together forming the mechanical joint restraint; inserting at least a portion of the gasket of the mechanical joint restraint into a socket of a piping element; inserting the end of the pipe length into the socket of the piping element; and drawing the gland towards a flange of the piping element to compress the gasket into sealing engagement with the piping element and the pipe length.

A tarpaulin system for an open cargo hold. The tarpaulin system includes a tarpaulin, a plurality of bows, a plurality of connectors, a cable, and a tail end system. The plurality of connectors connects the plurality of bows to the cable while the tarpaulin is draped atop the plurality of bows. The tarpaulin bracket system allows for quick, and easy, replacement, or fixing, of the plurality of connectors or damaged bows allowing for much easier and efficient replacement while traveling in harsh environments.

A joint having a male joint member and female joint member with enhanced ease of assembly, in which a raised stop on the male joint member is limited to displacement between a constriction on the female joint member and a locking ring segment, in which the locking ring segment and constriction are separated by an unobstructed traverse region that allows the male joint member to slide axially when under stress without separation from the female joint member, and in which a compressible spacer is installed between the male joint member and female joint member to ensure that the raised stop is installed in an intermediate position between the constriction and the locking ring segment. The compressible spacer withstands forces associated with assembly but allows the joint to compress during extreme events to prevent failure of the joint during extreme events, such as earthquakes, floods, and landslides.

The invention relates to a method for forming a fastening collar. A fastening collar is formed to the end of the tubular piece by shaping the end of the tubular piece in a first step by means of a first rotatable shaping head and a counter-surface to a first angle, and in a second step by means of a second rotatable shaping head and a counter-surface to a second angle. The outermost end of a flange part shaped in the first step is shaped in the second step in such a manner that only part of the flange part formed in the first step is shaped into a support surface that is perpendicular to the longitudinal axis of the tubular piece.

The present disclosure provides flanged joint or interface between two passageways. The flanged joint includes a first passageway, a connector, and a second passageway. The first passageway may, but not necessarily, be formed via casting process wherein an integrated flange may be defined at the opening of the first passageway such that the integrated flange defines a recess. The connector includes a support body having a fastener region at an upper end of the support body and a flange region at a lower end of the support body. The support body defines an aperture which is configured to support the second passageway. The flange region defined in connector is configured to engage with a recess defined in the first passageway.

A pipe connection device according to the present invention includes: a connection member including a projection in which an insertion space is formed in the projection and a pipe is inserted through one side and which is bent in a circumferential direction at the other side and a separation preventing unit which is spaced apart from the projection and protrudes in the circumferential direction; and a flange member coupled to the circumference of the connection member between the projection and the separation preventing unit so as to contact the projection and having a joining hole penetrated by a joining member.
