Systems and methods for a coupler including: a cable comprising a bend relief disposed at an end of the cable and one or more wires; a socket comprising one or more pins and one or more socket terminals, where the one or more pins are electrically connected to the one or more socket terminals; and a housing body disposed between the cable and the socket, where the housing body comprises a portion of the bend relief and the one or more wires connected to the one or more socket terminals, and where at least a portion of the housing body is made of hot melt such that the housing body encapsulates the portion of the bend relief, the one or more socket terminals, and the one or more wires connected to the one or more socket terminals.

A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.

A method for monitoring a curing process of a cured-in-place pipe is disclosed. The method includes affixing a plurality of sensors to a resin layer of a liner, and determining a curing profile corresponding to at least the resin layer, the curing profile including a threshold curing value. The method further includes sensing, using the plurality of sensors, real-time data indicative of at least one curing parameter. Additionally, the method includes comparing the real-time data from each sensor to the threshold curing value, and outputting an alert upon the real-time data meeting or exceeding the threshold curing value.

The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.

Weld seam testing chain for testing a weld seam by means of ultrasound on two plastic tubes welded together at the ends, comprising standard chain links, wherein the standard chain links are hooked together to form the weld seam testing chain, and the chain can be lengthened or shortened individually, a sensor receptacle for accommodating the ultrasonic sensor, and an adjusting unit for the fine adjustment of the weld seam testing chain length, wherein the standard chain links have a hook on one side and a hook receptacle on the opposite side, thereby enabling the individual chain links to be hooked together.

A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.

A method of welding/joining corrugated pipe segments, an apparatus configured to weld/join corrugated pipe segments, and a method of circulating water are disclosed. The method of welding/joining corrugated pipe segments includes holding or securing an end of each of the corrugated pipe segments with a jig, and welding the ends of the corrugated pipe segments together. The jig includes at least two rings, each configured to receive one of the ends of the corrugated pipe segments, and a brace or connector connected to each of the two rings. The apparatus includes the jig, a welding ring configured to receive the ends of the corrugated pipe segments, a resistive heating coil for heating the welding ring, and a control circuit configured to control a temperature of the resistive heating coil and maintain the temperature of the resistive heating coil once a target temperature is reached.

A connection device for plastic pipe elements (1) which allows performing pre-assembly and being finally assembled without requiring skilled labor, having a pipe element (1) with at least one end, a plastic connection element (2) which is connected to an outer surface of the pipe element (1) through the end, which has a resistance wire (3) wound on the outer surface of the pipe element (1) itself.

A method and apparatus for inspecting a fusion joint is provided. The apparatus includes a processor, an ultrasound (“US”) probe in communication with the processor, and a database comprising classification rules. The processor is configured to generate an initial set of US scanning positions about the fusion joint based on information of at least one of the US probe and the fusion joint; measure, via the US probe, a US pulse-echo spectrum from at least two of the initial US scanning positions; compare each measured US pulse-echo spectrum with one or more known US pulse-echo spectrums; classify each measured US pulse-echo spectrum according to the classification rules; and evaluate an aggregate of measured US pulse-echo spectrums to determine if the fusion joint is defective.

One fusion machine can butt or socket fuse polyolefin pipes and fittings in straight alignment or at inwardly or outwardly mitered universal angles from 0° to 45° for butt fusion and from 0° to 10° for socket fusion. The machine is manually driven, hydraulically monitored and operated in all configurations from one side of the machine.
