A pipe union assembly that includes a female end of a first pipe section and a male end of a second pipe section. The pipe union assembly also includes a quick union nut securable to the female end, a retainer collar securable to the quick union nut and a segmented load ring disposed between the male end of the second pipe section and the quick union nut. The quick union nut, the retainer collar and the segmented load ring cooperate to maintain the male end of the second pipe section inside the female end of the first pipe section. A method of using the pipe union assembly to join a first pipe section and a second pipe section.

A union connection common in connecting pipelines in various industries comprises a threaded female pipe end, a male pipe end insertable into the female pipe end to form a sealed connection, a plurality of shaped ring segments and a threaded collar in which the shaped ring segments are placed in a shaped groove on the male pipe and positioned in the threaded collar. The threaded female pipe end is then threaded onto the threaded collar, the threads each being clocked so as to press the collar against the male pipe using the ring segments and into a sealed connection with the female pipe. A pin inserted through a pin hole in the collar and into a pin recess in the female pipe end holds the parts in place. The pin hole and pin recess are positioned relative to the clocked threads of the collar and female pipe.

This disclosure provides systems, methods, and devices for a coupling device. In an aspect, a coupling device is configured with at least one fastener for compressing and also opening the coupling and a pushing bolt configured to apply an unlocking force on an object to be coupled by the coupling device. In another aspect, a method for engaging or disengaging a coupling device is disclosed. Other aspects and features are also claimed and described.

A connection verification tool for verifying a secure connection between two fluid handling components of a fluid handling system. A connection verification tool can include a gauge portion sized sized to be placed over a first fluid handling component connected to a second fluid handling component to verify a secure connection between the two components. If the first fluid handling component is not securely connected to the second fluid handling component such that additional torque may be required to complete the connection between the two components, the gauge portion of the connection verification tool will not fit over the first component coupled to the second component.

A flexible dual duct coupling, comprising: a coupling body having an inner flow passage and an outer flow passage therethrough; a first nut assembly configured for reversible attachment to the coupling body; and, a second nut assembly configured for reversible attachment to the coupling body, wherein the second nut assembly is opposite the first nut assembly.

The invention is a tapping assembly for use on a pipe or tank. It includes a hollow body that sits flush on the outer wall of the pipe or tank and includes a plurality of locking members that sit flush within the body and form a threaded portion into which a cap is inertable. Each locking member extends into the interior of the pipe or tank, and has an outwardly extending flanged portion that engages with the inner sidewall of the pipe or tank. When the cap is tightened against the body, it causes each of the locking member to retract, thereby causing the respective flange portions to lock the assembly against the pipe or tank wall. The assembly can be manufactured to provide either an orthogonal tap, or an angled tap, relative to the longitudinal axis of the pipe, or plane of the tank sidewall.

A socket unit for a capillary connection system, especially for use in HPLC applications, includes a housing with a housing outer surface and a housing inner surface that define a housing axial cavity. The socket unit also includes a socket connecting mechanism adapted to engage with a corresponding plug connecting mechanism of a plug unit to connect the plug unit and the socket unit together, wherein the socket connecting mechanism is adapted for a predetermined number of discrete connection states between the socket unit and the plug unit.

A thermal module for pre-heating liquid flowing into a liquid chromatography column, includes a trough compartment with two ends, one of the two ends having an electrical socket, a first fluidic assembly, a second fluidic assembly, and a clamp assembly. The clamp assembly includes a rail configured to receive the first fluidic assembly. The clamp assembly includes a carriage slidably mounted to the rail and configured to receive the second fluidic assembly. The carriage is operable to establish a first fluid tight seal between the first fluidic assembly and a chromatography column received within the clamp assembly, and to establish a second fluid tight seal between the second fluidic assembly and the chromatography column. The clamp assembly is disposed within the trough compartment, and the first fluidic assembly is plugged into the electrical socket at the one end of the trough compartment.
