Abstract: A method of manufacturing a gusseted pinch bag from polypropylene. A sheet or seamless tube of polypropylene is provided. The sheet is preferably comprised of one or more layers of axially and/or biaxially oriented polypropylene. Perforation lines in a pinch pattern are formed in the sheet or tube. Preferably a laser forms a series of small, closely spaced holes in the sheet along the perforation line. The laser heats the plastic surrounding the holes, causing the polypropylene molecules between the holes to lose their orientation. Thus, the polypropylene in the perforation line between the holes is substantially weakened. If a sheet is used, it is folded into a gusseted tube and the edges are sealed together to make a tube. If a seamless tube is used, the tube is gusseted. In either case, a lateral force is then applied to the terminal tube, breaking the perforation line and separating the terminal tube from the sheet. The bottom end of the tube is then sealed, thereby forming a bag.

Abstract: A soft shell, flexible storage tank is provided, including corners of an improved configuration adapted to resist leaks. The walls of the tank and the corners are relatively more rounded and larger in radius than those of conventional flexible tanks. The walls and the improved corners act together to resist leaks. The rounded corners tend to reduce the effective pressure in the tank walls by loading the seams predominantly in shearing stress when the tank is filled with a liquid. The rounded corners are developed as panels, which are thermally bonded to produce secure and reliable liquid-tight seams. Each of the panels is bonded by lapped seams to others of the panels. Each of the rounded corners includes a generally triangular corner that is bonded to at least three other panels. In effect, the flexible storage tank functions as a pressure vessel, which tends to resist leakage.

Abstract: A process for producing high pressure tubing from austenitic stainless steels. The process entails passing a continuous austenitic stainless steel strip through pre-weld rolls enclosed in a forming housing to produce a continuous tubular shape having opposing edges separated by a longitudinal gap. While the gap is maintained with a seam guide and a liquid-free gas mixture of an inert gas and a gaseous flux is directed at the gap and into an interior of the tubular shape, the tubular shape is caused to pass through a high frequency induction coil to cause heating of the opposing edges of the tubular shape. Pressure is then applied to the tubular shape with weld rolls to force the opposing edges together and form a continuous tubing having a continuous butt weld joint. The weld joint is then quenched with an inert gas without the assistance of a liquid coolant.
