A pipe connector for use in high temperature environments, such as those characteristics of molten salt reactors. The pipe connector can be used in any industry that uses pipe connectors, and in particular, can be used in a molten salt system including a reactor requiring a connection rated for greater than 700 C. and up to 15,000 psi. The pipe connector 100 may comprise a pin 110, a seal ring 140, a retainer ring 150, a box 160, a locking nut 180, and a retaining nut 190.

A pipe socket for making a threaded pipe connection that includes: a socket body defining a threaded portion, a cavity and a stop; an O-ring positioned within the cavity; and a plurality of interrupted series of tapping threads defined on an internal surface of the socket body in the threaded portion. The cavity is configured to receive a pipe and the stop is configured to stop a pipe received within the cavity. Each of the interrupted series of tapping threads is circumferentially equidistant from the adjacent interrupted series of tapping threads. Further, each of the interrupted series of tapping threads comprises threads arranged axially on the internal surface of the socket body for forming threads on a pipe received within the cavity.

Disclosed is a connecting device for piping for connecting a pipe to another pipe or to another part for piping. The connecting device includes an adapter and a pipe nipple configured to be threadedly engaged with the adapter. The pipe nipple is fixed to an end of a pipe, and an end of another pipe is inserted into the adapter. The adapter includes a hollow adapter body, a cap coupled to the adapter body, a grip ring configured to fix the pipe introduced into the adapter body, a body-sealing member configured to provide a seal between the adapter body and the pipe, a sleeve disposed between the grip ring and the body-sealing member, and a metal sealing member configured to provide a seal between the adapter body and the pipe nipple.

Techniques for implementing a pipeline system that includes one or more pipe segments, in which each pipe segment of the one or more pipe segments includes tubing that defines a pipe bore and a fluid conduit implemented in an annulus of the tubing, and a re-deployable pipe fitting to be secured to the one or more pipe segments. The re-deployable pipe fitting includes a fitting body that defines a fitting bore through the re-deployable pipe fitting and a threaded fitting jacket to be deformed around the tubing of a pipe segment of the one or more pipe segments to facilitate securing the re-deployable pipe fitting to the pipe segment. The threaded fitting jacket includes jacket threading that enables the threaded fitting jacket to be coupled to the fitting body, removed from the fitting body, or both without using hot tooling.

In a connection structure for fire extinguishing system piping in which a male piping member is connected to a connection opening portion of a joint by screwing a male thread and a female thread together, the male piping member includes a joint cylinder having a protruding portion that is inserted deeper into the connection opening portion than the female thread. Each male piping member and the connection opening portion includes a step portion. The connection structure further includes an indicator that engages the step portions and in a state in which the male piping member and the connection opening portion are connected together. At least one of the male piping member and the connection opening portion includes an unmountable portion that has an outside diameter different from an inside diameter of the indicator and cannot be engaged by the indicator.

A connection apparatus for sealing to a pathway of a mounting structure includes a body; and a port including a threaded portion extending from the body and a non-threaded portion extending from the threaded portion, the non-threaded portion carrying a gasket, the gasket positioned along the non-threaded portion such that the mounting structure to which the connection apparatus is mounted contacts the gasket prior to the threaded portion engaging a mating threaded portion of the mounting structure, the port providing fluid communication between the body and the pathway of the mounting structure. The body may be that of a valve that supplies any of air, water or oil as an operating fluid to, for example, inlet and outlet valves and a pump chamber of a medical fluid pump of a medical fluid delivery machine.

A cap loosening prevention device prevents a cap from loosening when the cap is fitted to a body. The device includes a body ring formed in a circular shape along the circumference of the body and having a cut portion. A protruding part is formed on the outward surface of the body ring. The protruding part has an incline with respect to the outward direction of the body ring, and the uppermost end of the protruding part is cut perpendicularly with respect to the outward direction of the body ring. The cap is prevented from completely loosening in the direction opposite to the rotational direction of the cap when the cap is fitted to the body, such that the cap can be firmly coupled to the body without separating from the body. The rotation of the cap is minimized to enable a rapid operation when a pipe is replaced.

A flange assembly for supporting a cable has a flange body and an armor retainer. The flange body and the armor retainer are configured to support a cable by compressing an armor layer of the cable against the armor retainer. The armor retainer and the flange body are separate pieces, that are removably attachable to one another.
