摘要： A swivel flange seal joint assembly which includes a tube having an integral, enlarged ferrule and swivel flange is described. The ferrule is enlarged and includes oversized fastener openings configured to allow circumferential alignment between the swivel flange and openings in a mating surface. The assembly also includes a gasket having openings, and the gasket is positioned between the ferrule and the mating surface so that a seal is formed between when the fasteners which extend through the flange, ferrule, gasket and mating surface openings are tightened.

摘要： To produce a flanged pipe unit, a separate flange is put on a pipe and then the pipe is subjected to a punching to achieve an interlocked connection between the flange and the pipe. The flanged pipe unit produced by the method of the invention comprises a metal pipe including a larger expanded portion, a smaller expanded portion and a raised portion which are axially aligned so that the smaller expanded portion is placed between the larger expanded portion and the raised portion; and a metal flange having a through bore through which the pipe passes, the through bore including a larger diameter portion, a smaller diameter portion and a tapered end portion which are axially aligned so that the smaller diameter portion is placed between the larger diameter portion and the tapered end portion. The larger expanded portion, the smaller expanded portion and the raised portion of the pipe are intimately engaged with the larger diameter portion, the smaller diameter portion and the tapered end portion of the through bore respectively thereby to establish a dove-tail coupling between the pipe and the flange.

摘要： The invention relates to a flange joint assembly for connecting together cylindrical duct sections. A tubular slip collar fits within opposing sections which engage an exterior projecting bead encircling the exterior of the slip collar. Opposing flange clamps are mounted on the ducts having leaf elements pressing against the duct surfaces. Opposing band clamps are mounted around the leaf elements securing the leaf elements to the duct surfaces. Opposing V-band ring locking devices encircle the flange clamps. In the alternative, Van-Stone flange rings secure the flange clamps together by means of locking bolts.

摘要： A connector for a composite pipe includes a male conical member to be inserted between inner and outer layers of the pipe. The outer layers have oppositely wound composite strips which are overlapped along the conical surface. The ends of the strips are braided and a cup located over the conical surface. A filler is injected between the cup and conical member to fill the voids formed between the overlapping strips.

摘要： A pipe coupling device for holding a metal pipe having a selected diameter within a range of a nominal diameter plus or minus a specified tolerance is also useful for easily determining if any pipe is within specifications. A split metal ring having a diameter equal to the nominal diameter for the metal pipe and a transverse split having a width equal to the specified tolerance is placed around the pipe. A flange having a tapered cylindrical bore having diameter such that the diameter plus twice the thickness of the split metal ring equals the nominal diameter of the metal pipe plus the specified tolerance is fitted over the split metal ring. If the pipe is undersized it will slip through the split metal ring. If the pipe is oversized the flange will not fit completely over the metal ring surrounding the pipe.

摘要： A pipe flange is formed with an opening into which is fitted a pipe, and an annular groove which is coaxial with the opening and surrounds the same. A cylindrical is defined between the opening and the annular groove coaxially. A folding-back portion is led to the cylindrical portion and is adapted to retain one leading end of the pipe fitted into the opening. A pipe retaining portion is led to the folding-back portion and is folded back radially inwardly over the cylindrical portion in parallel therewith and is spaced apart therefrom by a predetermined distance. Therefore, the joining process can be simplified, and the work environment will not be contaminated. In addition, the joint strength and the air tightness can be enhanced. The pipe integral with the flange for pipe fitting is light in weight. Furthermore, the present invention is adapted for the mass production by the simple joining method.

摘要： A method is shown for forming a flange on an end of a plastic pipe liner of the type used to line a tubular member. A reinforced disc having a rigid portion and an elastomeric portion is placed about the liner exterior and moved into position flush with the flanged end of the tubular member. A retaining ring is placed about the reinforced disc and the disc and liner exposed end are heated to render the materials malleable. A forming unit is then used to apply force to the liner to flow the liner into a reformed shape having a greater external diameter than the remainder of the liner. The forming operation also bonds the reinforced disc to the reformed liner end to further resist any tendency of the liner end to be retracted into the interior of the tubular member.

摘要： An improved fixing arrangement includes a planar flange having a mounting hole formed through an axial portion thereof, a radially expanded portion being formed in a portion of the peripheral surface of the mounting hole for receiving an annular resilient sealing member; and a pipe having one end provided with an pipe-diameter portion and a radially expanding annular portion. The radially expanding annular portion is engaged with the peripheral edge of the mounting hole which is formed on the back side of the flange to insert the pipe-diameter portion into the mounting hole. In addition, within the mounting hole, the end of the pipe-diameter portion is enlarged or a part of the pipe-diameter portion is radially expanded to press the resilient sealing member and to clamp the radially inwardly projecting peripheral edge of the mounting hole between the radially expanded portion and the enlarged end or radially expanded end portion, thereby fixedly connecting the flange and the pipe.
