A protective guard for a medical tubing connector includes a ring, at least one flexible member attached at a first end to the ring and having a second end, and a base attached to the second end of the at least one flexible member. The ring is configured to fit over a first connection member of the medical tubing connector, while the base is configured to fit over a second connection member of the medical tubing connector. When coupled with the medical tubing connector, the protective guard helps prevent a user from touching the medical tubing connector.

A technique facilitates formation of a connection between a first component and a second component. The first component and the second component may each comprise a tubular component. Additionally, the second component is secured to the first component via a coupler which is constructed to establish a hydraulic chamber between the coupler and at least one of the first component and the second component. Application of hydraulic pressure in the hydraulic chamber causes a desired preloading of the first component and the second component across the connection.

Provided is a corrosion prevention connector for preventing corrosion and pinhole leaks in potable water copper or lead piping systems. A length of copper, iron, or lead pipe is surrounded by a galvanize made of a metal or metal alloy less noble than, e.g., iron alloy, zinc, aluminum, magnesium, titanium, and/or alloys thereof. The galvanize is metallurgically attached to the length of copper or lead pipe. When the corrosion prevention connector is electrically attached to the copper or lead piping systems at one end and attached to a plastic (or other non-electrically conductive material) main or lateral at the other end, the potable water copper or lead piping system is maintained at a potential above the cathodic redox reaction potential of the chemical reaction between copper or lead pipes and the purification chemicals contained in the potable water. Thus, preventing the internal pipe corrosion and pinhole leeks caused by the redox chemical reaction between the pipe interior and the protective concentration of purification chemicals intentionally left in the purified drinking water. The connector also acts as a sacrificial anode to protect the exterior of the pipe from corrosion.

A method of protecting a layered coating on a length of pipe for subsea use includes applying an edge finisher to the coating to encase an edge of the coating by fusing the edge finisher with the coating or by molding the edge finisher at an edge of the coating. Where the coating and the edge finisher are of thermoplastics such as PP, fusing can be achieved by injection molding the edge finisher or by welding a discrete edge finisher component to the edge of the coating. Mirror welding may be employed for this purpose, with a hot plate being interposed between the edge of the coating and the edge finisher.

A polymeric device for protection of the connecting pipe coupling contains a stepped bushing having a medium part with an increased diameter and two lateral parts with a smaller outside diameters, which is installed between end faces of pipes with a conic thread, and connected by means of a coupling and having sealing rings made of an elastomer, which are on parts of the bushing with the small diameter. The device has an additional stepped bushing, and the first stepped bushing has a constant outside diameter and two parts with small and large internal diameters, and the second stepped bushing has a constant internal diameter and two parts with small and large diameters.

A heat-shrink sleeve is provided for covering a pipe joint formed between two pipes that are coupled to one another to form a tube. The heat-shrink sleeve comprises a heat-shrinkable material that is configured to conform to the first and second pipes when heated to cover the pipe joint.

Herein is a coupler and a clean connection device having the same, which can automate a series of operations for connecting and disconnecting a male coupler to and from a female coupler, clean and dry a wetted portion, drain residual liquid of chemicals together with cleaning water without external leakage in safety when the coupler is separated, and clean and dry the wetted surface before connection and after separation, thereby enabling a clean connection.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

A method for forming a high temperature field joint between two insulated pipe sections, and an insulated conduit having a low temperature field joint. The conduit comprises a steel pipe with a corrosion protection coating and a pipe insulation layer comprising a polymer composition having thermal conductivity of less than about 0.40 W/mk, and/or heat resistance to continuous operating temperatures from about 150° C. to above about 205° C. After a circumferential weld joint is formed between the two pipes, a first field joint insulation layer is applied over the joint area, the first field joint insulation layer comprises a polymer composition having heat resistance to continuous operating temperatures from about 150° C. to above about 205° C.
