PVC geomembranes be reduced and possibly discontinued. This is possible because of the development of a relationship between thermally welded seam burst strength and seam peel strength for a given sheet temperature. To develop this relationship, test welds were created using hot air and wedg...

1.The inspection and test of pipes engineering shall be carried out on the basis of self-inspection by the construction unit. Inspection and test the procedure ofPVC piping system, inspection batch or sub-item engineering, and record it at the same time. ...
The test procedures were: inherent viscosity, bulk density, dry contamination, fisheyes, dry-blend time, particle-size distribution, and PVC resin color. Statistical quality control (SQC) charting with root-cause analysis identified mechanical, environmental, and procedural sources of variability. Even...
The project specifications required the 40 mil PVC geomembrane to be installed with all production field seams constructed using dual track thermal fusion welds. The dual track weld leaves an unbonded area between two parallel welds that can be air pressure tested. With this technique, the entire ...
(including a core scanner for photographic description). The cores were then immediately inserted into PVC tubes and axially constrained with bar clamps. The annulus was then filled with epoxy (Sikadur-52). The annulus between the core and the PVC tube was chosen to be small (nominal 3.2...
