A method for inhibiting separation of joined pipes including providing within a pipe bell a gasket including rigid segments, each segment having bell teeth configured for engaging the bell and a spigot tooth configured for engaging a pipe spigot seated in the bell. Upon pressurization and over-pressurization of the joint, resulting axial forces exerted on the joint, which can cause pipes to separate, are countered by wedging the segments between the bell and the spigot and rotating each segment so that the thrust forces are directed radially. To prevent radially-directed thrust forces from damaging the joint through over-rotation of the segments, the bell teeth and the spigot tooth are adapted and arranged to maintain the thrust forces load path carried by each segment within a desired angular range relative to the spigot by transferring the load path between adjacent bell teeth whereby the effective length of each segment is increased.

A mechanical piping system and method is described herein. The system includes a first pipe with a first connection element disposed on an outer surface of the first pipe. The system also includes a second pipe with a second connection element disposed on an outer surface of the second pipe. An alignment element may also be included, with the alignment element creating a sealed flow path through the first pipe and the second pipe. Also, an external collar assembly may be included. The external collar assembly may engage the first connection element and second connection element and laterally secure the first pipe relative to the second pipe.

The present invention relates to an apparatus and a system and method for clamping axially extending articles with a new type of two-part clamp comprising an interlocking upper and lower clamp with a feeding mechanism for successively and repeatedly clamping cable and wire looms and harnesses, pipe, nipples, and hoses, and coiled electric cords in an assembly line. A clamp and clamping device are proposed which can, with precise control and flexibility and variable positioning, successively and repeatedly clamp wire looms and cable harnesses, pipe, nipples, and hoses, and coiled electric cords using as required a pressure reading plate in the inner circumference of the clamp on a controlled computer feedback loop to control piston thrust for interlocking a male half clamp within a female-half clamp. A manual tool employing the same clamp halves is also described. The invention is for use in the automotive, boating, electronic, aerospace, and space industries.

A pipe joining system and pipe joint are shown m which two sections of molecularly oriented pipe are joined using heat shrinking techniques. A first section of pipe is provided having a straight, pre-formed socket with an internal diameter and with an end opening having enough clearance to allow a mating spigot section having a given external diameter to be inserted into the socket end opening. After the spigot end is inserted to a given depth, the socket is heated sufficiently so that the internal diameter of the socket end comes into contact with the external diameter of the spigot end, the molecularly oriented pipe being in a rubbery state and exhibiting a low elastic modulus which allows the socket end to conform tightly to the spigot end external diameter without deforming the spigot end.

A method for coupling a fitting to a tubing end includes pressing a collar over the outer surface of the tubing until the strain on the collar in the hoop direction is at a predetermined level, or pressing a collar with a predetermined axial load.

A tube end form, including a first section including a first radially outward facing surface, a second section including a second radially outward facing surface, and a shoulder axially arranged between the first and second sections, the shoulder including a first frusto-conical surface arranged at a first angle relative to the first radially outward facing surface, and a second frusto-conical surface arranged at a second angle relative to the first radially outward facing surface.
