Abstract: A conduit coupling system, sealing device, bell, and method of use are disclosed herein. The system comprises at least two piping components, and a sealing device. A first component has a bell and a second component has a spigot, the spigot is adapted to mate with the bell. The bell comprises a first end and a second end, the first end coupled to the first component. The bell has a concave annular inner surface and a diameter of the annular inner surface adjacent to the first end of the bell is greater than a diameter of the annular inner surface adjacent to the second end of the bell. The sealing device comprises a locking segment comprising a convex outer surface and a K-type gasket coupled to a locking segment or a non-restraining anti-extrusion segment. The sealing device is adapted to fit between the bell and the spigot.

Abstract: A coating for a metal surface that provides excellent resistance to both electrochemical corrosion and mechanical insult is provided. The coating involves at least an inner coating that is a sacrificial anodic layer and an outer coating that is a protective dielectric material made of inorganic metal oxide. Some versions of the coating include an intermediate layer as well that serves to improve adhesion between the coatings and may provide additional galvanic protection. Although the coating can be made by a variety of methods, advanced methods of spray application are provided for making high-quality lightweight versions the coating.

Abstract: A protective coating for a metal substrate is provided that is light, durable, galvanically protective, and easily applied at the site of manufacture. The coating has at least two layers, one of which is a galvanizing layer and one of which is a micro-composite of a galvanic metal and a non-conducting material, such as polymer. Such coatings are useful for example to protect pipes or other metal surfaces in corrosive environments. Methods of producing the coating are provided, including methods that use advanced spraying techniques to provide very thin but consistent layers. Using the advanced spraying methods the composite layer can be created by co-spraying the galvanic metal and the nonconductive material onto the surface of the galvanic coating. Optionally, an outer coat of insulating material can be applied to provide further protection to the surface.

Abstract: A device for lifting and rotating objects is disclosed. The device includes a plurality of hooking protrusions that are in angled relation with each other and contain compound bends to permit engagement with the support structure of the object to be lifted.

Abstract: A mechanical pipe joint, restraining gasket, and method for restraining pipe spigots within adjacent bell sockets. The restraining gasket is composed of two axially-separate components: a sealing portion and a restraining portion made of a plurality of arcuate locking members. The restraining gasket and a gland surround an outer surface of the pipe spigot. The mechanical pipe joint is formed as the pipe spigot is inserted into the bell socket and the gland is axially attached to the bell socket so that the restraining gasket is held between: the gland, an inner surface of the bell socket, and the outer surface of the pipe spigot, so as to provide a fluid seal in the joint and urge the locking members into contact with the outer surface of the pipe spigot, axially restraining the pipe spigot within the bell socket.

Abstract: A gasket for connecting two lengths of pipe in a standard mechanical joint is disclosed, which gasket maximizes the advantages of both restrained push-on joints as well as mechanical joints, as are known commonly in the art. The invention has application to long-run pipe lengths as well as appurtenances, including fittings and connections. The gasket contains locking members that act to restrain separation upon the instance of any force tending to separate the connected pipe lengths.

Abstract: A locking segment for use in connecting two lengths of pipe has a radically extending heel that serves as a rotational brake. By mating the brake into an annular trough, that is, by placing it between two walls, the rotation of the segment can continue only until points on the brake mure between the two walls. Rotation of the segment in response to increasing thrust pressures can thereby be arrested before the rotation causes the segment to bear on the spigot with a radially inward force great enough to penetrate the spigot.

Abstract: A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket and an annular flanged portion having a notch for receiving a second sealing gasket. The flanged-pipe fitting is used in conjunction with a gland fitting to join the two ends of the pipe together.

Abstract: Corrosible metallic elements of tank are protected by an anodic encasement sleeve. The anodic encasement sleeve employs an inner sacrificial anodic layer and an outer environmental barrier layer to provide both cathodic and barrier protection against corrosion. Following application of the sleeve, typically by drawing or wrapping, the anodic encasement sleeve remains substantially unbonded from the tank, though it is electrically connected by conductive means. Because of the substantially unbonded relationship between the sacrificial anodic layer and the metallic elements of the tank, if electrolyte is present under the environmental barrier (due to breaches, installation error, condensation, etc.), the electrolyte may enter the unbonded area between the tank and the anodic material. This increases the ratio of anodic material to tank available, which makes the cathodic protection more efficient and effective for an extended duration.

Abstract: A non-contact measuring device for determining the dimensions of a cylindrical object, such as a pipe. The device may use a programmable industrial robot with an arm terminating in a rotary joint, or wrist. A non-contact measurement assembly, which preferably includes a triangulation laser, mounted to the robot's wrist. The wrist includes a binary wrist encoder for providing the angular position of the wrist to an attached computer. Likewise, the laser provides a signal representative of the distance from the laser to the surface of the pipe to the computer. The robot positions the measurement assembly in a predetermined location within the pipe and rotates the measurement assembly. The computer correlates the measurements from the lasers with the angular position at which they were taken, and it analyzes this data to determine the dimensions of the pipe, including the true profile of the surface and cross-sectional shape.
