International Classification:

B29C 65/00

US Classification:

264248, 1563042, 156503

Abstract:

Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes the steps of: removably positioning a first terminal edge of a first conduit portion with a first terminal edge of a second conduit portion; facing the terminal edges of the first conduit portion and the second conduit portion; aligning the terminal edges of the first conduit portion and the second conduit portion; melting at least a portion of the terminal edges of the first conduit portion and the second conduit portion; engaging the melted terminal edge of the first conduit portion with the melted terminal edge of the second conduit portion; maintaining pressure between the engaged terminal edges, thereby creating a fused joint area; and removing at least a portion of the resultant external bead extending around the fused joint area. A fusion apparatus for employing this method is also disclosed.

International Classification:

G01L 1/00

US Classification:

702 42

Abstract:

Disclosed is a method that provides for the calculation and prediction of hoop strength of an expanded pipe, preferably a PVC pipe or conduit. The method includes the steps of: (a) determining hoop strength as a function of relative wall thickness; (b) determining Wall Thickness Ratio (WTR) by dividing a nominal wall thickness of the original conduit by the minimum wall thickness of the expanded conduit; (c) determining long-term hydrostatic strength by at least one of hoop testing and burst testing; and (d) applying an accelerated regression analysis to the results in step (c), yielding a Hydrostatic Design Basis (HDB). The resulting HDB may be plotted against WTR to provide the user with graphical data for use in making design decisions and choosing specific conduit for specific applications.
