A pipe coupling construction which can be used for coupling of a high-pressure pipe includes an inner bush of a non-metallic material and an outer bush, which bushes in axial section have parts which mesh with each other in order to transmit axial forces. The inner bush can be fused or adhered to an outer cover layer of the pipe. The coupling has a metal sleeve construction. The outer bush has an outer bush protruding end which protrudes with respect to the inner bush and the metal sleeve construction is at least partially located within the outer bush protruding end. The metal sleeve construction and outer bush in axial section have parts which mesh with each other.

A bonding clip is provided in combination with a fluid conduit coupling that interconnects fluid conveying members. The bonding clip conducts electrical charge across the coupling to prevent buildup of electrostatic charges in the coupling. In one aspect of the invention, it may be considered a bonding clip. In another aspect, it may be considered the combination including the bonding clip and coupler. The invention also includes a method for dissipating electrostatic charge across a coupling used to interconnect fluid conveying members. In a preferred embodiment of the bonding clip, it includes a continuous flexible wire element mounted exteriorly of the coupling. The bonding clip is formed in a shape to connect the facing flanges of adjacent fluid conveying lines connected by the coupler, and to pass over the coupler with a defined gap separating a bridge portion of the clip from exterior surfaces of the coupler.

There is provided a safety lock for a hose connector and valve on a flow line having an anchor that is in a fixed position relative to the valve, a movable body movably attached to the anchor, and a shroud and an actuator blocking member carried by the movable body. The shroud is sized and positioned on the movable body to limit access to the hose connector when the movable body is in a first position, and to permit access to the hose connector when the movable body is in a second position. The actuator blocking member is sized and positioned on the movable body to prevent the valve actuator from moving from a second to a first position when the movable body is in the second position, and to permit movement of the actuator when the movable body is in the first position.

A check valve between two pipe segments including a valve body and a valve housing. The valve body includes a valve opening through one face with a valve seat therearound, and a wall extending between the faces defining a part of the circumference of the fluid line between the pipe segment ends with a radial opening in the other part of the fluid line circumference having no wall. The valve housing is removably securable over the radial opening whereby the valve body wall and the valve housing together define a closed circumference of the fluid line between the pipe segments. A valve flapper is secured to the valve housing and pivotally biased relative to the valve housing toward closing against the valve seat, whereby the valve flapper is removable through the valve body radial opening when the valve housing is removed from the valve body.

A pipe repair apparatus is provided. The pipe repair apparatus includes a cap. The cap includes a cylinder shape having a front edge forming an opening into the cap, a rear edge forming an opening into the cap, and at least a first side edge and a second side edge. The cap may further include a cap flange formed at the front edge having a first bend in a direction towards a central longitudinal axis of the cap and a second bend in a direction away from the central longitudinal axis of the cap. The cap is sized to fit over a pipe so that the first side edge overlaps the second side edge. A clamp secures the cap to the pipe.

A flange adapter is provided for positioning an insert device within a pressurized fluid system. A flange adapter assembly includes a pressure containing boundary and a flange adapter configured to be selectively connected to the pressure containing boundary. The adapter is configured to interchangeably fit a plurality of flange standards for the same nominal size. The adapter may also interchangeably fit a plurality of pressure ratings for the same nominal size. The flange adapter may be manufactured separate from the pressure containing boundary to allow for utilizing less costly material and to increase standardization of safety heads. The present invention also includes a gasket design having multi-flange compatibility for use in pressurized fluid systems.

The present invention discloses a fully visual flow loop system for studying hydrate blockage. The fully visual flow loop system includes a first pipeline, a second pipeline, a third pipeline and a fourth pipeline connected successively in an end-to-end way; a single screw pump is connected between the first pipeline and the fourth pipeline from the four pipelines; the first pipeline, the second pipeline, the third pipeline and the fourth pipeline are all transparent to light; a plurality of CCD cameras are arranged between the first pipeline, the second pipeline, the third pipeline and the fourth pipeline; and, the fully visual flow loop system is arranged in a stepping low-temperature thermostatic chamber; a solution injection system can inject a solution into the fully visual flow loop system; a separation and collection system can separate and recover the solution; and a data acquisition system can integrate sensor information in all the other systems and give real-time feedback to ensure reasonable and coordinated operation of all systems. The fully visual flow loop system for studying hydrate blockage in the present invention can realize full visualization and real-time monitoring of the flow loop system.

The present disclosure provides a fluid introducer for a piping system that includes first and second piping sections. The fluid introducer provides a direct connection to the first piping section through a separator body configured to be positioned in an expansion gap between the first piping section and the second piping section such that a first end face of the separator body faces the first piping section and a second end face of the separator body faces the second piping section. The fluid introducer is configured to direct fluid from the fluid source through fluid introduction passaging into the first piping section and block the fluid from flowing into the second piping section.

The present invention relates to a device 100 for connecting a gas-conducting conduit element 1, in particular a hydrogen-conducting conduit element, to a counterpart 2, in particular a component, comprising: at least one screw body 10, which is configured to be brought into tight engagement, in particular into gas-tight engagement, with the counterpart 2; a first seal 3, which is in the form of a valve body 3a which is configured to be brought into contact, in particular into gas-tight contact, with a valve seat 4 provided on the counterpart 2, or which is in the form of a flat seal; and a second seal 5 which operates on a sealing effect principle according to which the sealing effect is exerted or deployed irrespective of an axial displacement, in particular in an installation direction E, which is necessary for creating the sealing effect of the first seal 3.

A leak indicating clamp utilizes a bracket clamp, a flag body, and a flag cap that enables quick identification of leaks within various pipe-based systems.
