  • Publication number: 20080245471
    Abstract: A method and apparatus for lining process tanks. The method comprises lining a tank with a plurality of sheets, wherein the tank has walls and a bottom that intersect at a corner of the tank. The method comprises bonding a bottom sheet of the plurality of sheets to the bottom of the tank. Next, a pair of sheets of the plurality of sheets are bonded to adjacent walls of the tank and above the bottom sheet, each sheet of the pair of sheets having a first edge and a second edge such that the first edges of the pair of sheets are positioned at the intersection of adjacent walls of the tank to position an interface between the pair of sheets. The method also comprises extrusion welding the pair of sheets together by infusing a molten thermoplastic material along the pair of sheets and within the interface of the pair of sheets.

  • Patent number: 7111497
    Abstract: A leak detection apparatus detects leaks or premature wearing in a lined fluid filled vessel. A leak detection apparatus comprises a current density meter, a power supply, and a probe. The probe is inserted into the fluid filled vessel. The power supply supplies an AC or DC electric current to a directional amplifier of the probe. A torroid of the probe senses the current density in the fluid and sends an electrical signal to the current density meter. The current density meter measures the electrical signal and communicates a current density readout to a display. This readout indicates to an operator whether or not there is a crack, premature wearing, or a bypass.
