Disclosed is a connection comprising first and second lined tubular members having a coincident bore and a protective ring. The first lined tubular member has a pin end and the second lined tubular member has a box end. Each lined tubular member includes a tubular body, an annular liner, and a mortar filled annulus therebetween. The mortar filled annulus has an annular recess therein at at least one of the pin end and box end for receiving a part of the protective ring. The part received may be a flange on the ring.

A fluid connector for connecting fluid conduit to a component in the presence of an electrolyte solution includes a connector body and sacrificial anode. The connector body defines an internal recess. The sacrificial anode can be press-fitted into the internal recess and circumscribed by the connector body. The sacrificial anode, which is constructed of a material that is configured to be consumed over a life of the component to prevent or delay corrosion of the connector body due to contact with the electrolyte solution, may be constructed of aluminum, magnesium, zinc, or other active metals. A fluid system for use in the presence of the electrolyte solution includes the component, fluid conduit, a pump, and the fluid connector. A vehicle includes the fluid system and a vehicle body. The component may be a steering gear assembly in some embodiments.

A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation layer, an interstitial adhesive layer, and a lubricating material layer. The base adhesive layer adheres to the device's surface thus enabling the coating to form a sealing liner. The intermediary insulation layer is positioned in between the base adhesive layer and the interstitial adhesive layer. As a result, the intermediary insulation layer prevents negative chemical interactions between the base adhesive layer and the interstitial adhesive layer. The lubricating material layer is super imposed onto the interstitial adhesive layer to provide a friction-reducing coating for the device's surface.

The metal connector or adaptor for hydraulic or oil dynamic application at high pressure, comprises electrolytic passivated zinc plating free from hexavalent chromium, the zinc plating comprising an external trivalent chromium passivation layer, said passivation layer having a distinctive unique coloration among high corrosion resistance processes.

Bellow of a flexible material for protecting a coupling comprising first and second connector end subject to vibration and torsion. The bellow comprises a material able to prevent material from entering or exiting the space between the connector ends. The bellow is arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp. The bellow is provided with a zipper comprising a zipper slider and first and second zipper part attached to opposite ends of the sheet. Thus, the bellow can be wrapped around said first connector end and second connector end and closed by zipper.

A pipe liner for lining a fluid-carrying pipe, the pipe liner comprising an elongated flexible conduit and a flexible flange. The flexible conduit includes an outer wall forming an open-ended central channel for allowing fluids to be pumped therethrough. The flexible flange extends radially from one end of the elongated conduit and includes a number of fastener holes. The flexible conduit and the flexible flange are configured to be collapsed and pulled through the pipe such that the flexible flange can be connected to a rigid flange of the pipe via the fastener holes. The pipe liner is less prone to leak and is easier to transport and install.

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

A tube assembly (12) including an inner tube (13) having an outer thread (15), an outer thread (14) having an inner thread (16) engaging the outer thread (15), at least for securing an angular position between the inner tube (13) and the outer tube (14) is provided. Such a tube assembly should facilitate mounting and maintenance of a reverse osmosis system. To this end, the inner tube (13) includes at least an groove (17) on its outer surface and the outer tube (14) includes an recess (18) on its inner surface, wherein a blocking element is arranged in a space formed by the recess (18) and the groove (17) in overlapping relation with the groove (17) and the recess (18).
