Abstract
A discrete flanged element is adapted to surround and connect a plain end of pipe 44 to a standard flange 22 of an adjoining section of piping and includes an integral flange ring 12, an annular gasket recess and a securing hub 16. The flange ring 12 has an axially exposed planar face 18 for mating with the face 24 of the standard flange, bolt holes 20 at standard positions corresponding to those of the standard flange, and an inner diameter greater than that of the face of the standard flange. The annular gasket recess lies inwardly of the flange ring and has an axially open side corresponding to the face 18 of the flange ring 12 and surfaces arranged to receive and position an annular gasket 32 so as to protrude through the open side of the recess and axially butt with the inner margin of the face 24 of the standard flange when the flange ring and standard flange and drawn together, thus producing a seal between the flanges and through compression to the surrounded pipe 44. The hub 16 of the flange element includes adjustable gripping bolts 36 for securing the flange element to the surrounded pipe preventing movement between the flange element and the pipe. <IMAGE>
Description
SPECIFICATION
Flanged element
This invention relates to piping flanges adapted to connect a plain end of pipe to a standard flange of an adjoining unit of a piping system.
Connection of a new or replacement piece of pipe to an adjoining standard flange has generally been accomplished by threading or welding another standard flange to the end of the piece of pipe whereby the new flange can then be bolted to the adjoining flange. Where threading or welding was not feasible, the same was accomplished by mounting on the end of the pipe a multi-piece flange assembly requiring a flared end portion of one piece and sealed connections first to the piece of pipe and then to the adjoining standard flange.
Such assembly has proved disadvantageous with respect both to cost and ease of installation.
The objects of the present invention are to provide a flange assembly which is simple, relatively inexpensive and easily attached to the end of an unthreaded piece of pipe.
According to the present invention there is provided a discrete flanged element adapted to surround and connect a plain end of pipe to a predetermined standard flange of an adjoining unit of a piping system, said element integrally defining a flange ring, an annular gasket recess and a securing hub; said flange ring having an axially exposed planar face for mating with the face of said standard flange, bolt holes at standard positions corresponding with those of said standard flange, and an inner diameter greater than that of the face of said standard flange; said annular gasket recess lying inwardly of said flange ring, adapted to receive a given gasket body that surrounds said pipe and having an axially open side corresponding to the face plane of said flange ring; surfaces of said flanged element defining said gasket recess arranged to position said given annular gasket body so as to protrude through said open side of said recess, exposed for axially butting with the inner margin of the face of said standard flange when said flange ring and said standard flange are drawn together, whereby said gasket can be sealed to said standard flange by said butting contact, and via compression produced by said contact, to said surrounded pipe; and said hub including adjustable gripping means for engaging and gripping said pipe to resist relative axial movement between said flanged element and said pipe.
In the accompanying drawings which illustrate an exemplary embodiment of the present invention:
Figure 1 is a cross-sectional view of the flange element;
Figure 2 is a top view of the flange element taken at line 2-2 of Figure 1;
Figure 3 is a bottom view of the flange element taken at line 3-3 of Figure 1;
Figure 4 is a cross-sectional view of the flange element of Figure 1, the surrounded piece of pipe and the annular gasket;
Figure 5 is a cross-sectional view of the flange element and annular gasket of Figure 4 indicating the means of connection between the flange element and a standard flange; and
Figure 6 is a cross-sectional view of the flange element and gasket of Figure 4 in a position fully abutting the standard flange.
Referring to Figures 1-3 and 5 the flange element 10 integrally defines a flange ring 12, an annular gasket recess 14 and a securing hub 16.
Flange ring 12 has an axially exposed planar face 18, and bolt holes 20 corresponding with those of a standard flange 22. The inner diameter D1 of flange ring 12 is greater than that of the inner diameter D2 of standard flange 22. The annular gasket recess 14 lies inwardly of flange ring 12, has an axially open side S corresponding to face plane 18 of flange ring 12, and has surfaces 26, 28 and 30 arranged to receive and position an annular gasket 32. Gripping bolts 36 extend through the sloping side 38 of securing hub 16 while clamping bolts 40 extend through bolt holes 20 in flange ring 12.
In operation, flange element 10 is slipped over the non-threaded end 42 of pipe 44, as shown in
Figure 4, so that the end of the pipe is on the same plane as the exposed planar face 18 of flange ring 12. When so positioned, gripping bolts 36 are tightened securing the flanging element to the pipe and preventing axial movement between the two. Once the flange element is properly secured, gasket 32 is positioned, as shown in Figures 4 and 5, within gasket recess 14. When so positioned, end portion 34 of gasket 32 protrudes through open side S outward beyond the face plane 18.
With gasket 32 in place, the flange element may then be connected to the corresponding standard flange. As shown in Figures 5 and 6, this is accomplished by butting face plane 18 of flange ring 12 against the corresponding face plane 24 of standard flange 22 in such a manner as to align bolt holes 20 of flange ring 12 with the corresponding bolt holes 48 of standard flange 22.
Clamping bolts 40 are then inserted through bolt holes 20 and 48, and nut 50 is attached to each such bolt. As shown in Figure 6, flange ring 12 and standard flange 22 are then drawn together through the tightening of nuts 50 on clamping bolts 40, whereby gasket 32 is sealed to the face of the standard flange by the butting contact of gasket portion 34 against the inner margin of the face of the standard flange. The compression produced by this drawing together also forces side 52 of gasket 32 into butting contact with the surrounded pipe thereby creating a seal between the flange element and the surrounded pipe.
1. A discrete flanged element adapted to surround and connect a plain end of pipe to a predetermined standard flange of an adjoining unit of a pipe system, said element integrally defining a flange ring, an annular gasket recess and a securing hub; said flange ring having an axially exposed planar face for mating with the face of

Claims (4)
1. A discrete flanged element adapted to surround and connect a plain end of pipe to a predetermined standard flange of an adjoining unit of a pipe system, said element integrally defining a flange ring, an annular gasket recess and a securing hub; said flange ring having an axially exposed planar face for mating with the face of said standard flange, bolt holes at standard positions corresponding with those of said standard flange, and an inner diameter greater than that of the face of said standard flange, said annular gasket recess lying inwardly of said flange ring, adapted to receive a given gasket body that surrounds said pipe and having an axially open side corresponding to the face plane of said flange ring; surfaces of said flanged element defining said gasket recess arranged to position said given annular gasket body so as to protrude through said open side of said recess, exposed for axially butting with the inner margin of the face of said standard flange when said flange ring and said standard flange are drawn together, whereby said gasket can be sealed to said standard flange by said butting contact, and via compression produced by said contact, to said surrounded pipe; and said hub including adjustable gripping means for engaging and gripping said pipe to resist relative axial movement between said flanged element and said pipe.
2. The flanged element of claim 1 wherein a surface of said element defining said gasket recess.
is sloped toward the axis of said element in the direction away from said open side of said recess, thereby arranged, in reaction to compression forces produced by butting of said annular gasket against said standard flange, to force said gasket radially inwardly thereby to tighten about the surrounded pipe.
3. A flanged element substantially as herein described with reference to the accompanying drawings.
4. Pipes connected by means of a flanged element according to any one of the preceding claims.
