Abstract
Disclosed herein are exemplary embodiments of linings, liners, and methods of providing a liner or lining for a tank. An exemplary embodiment includes a method of providing a liner or lining for a tank. In this exemplar embodiment, the method includes extrusion welding a pair of sheets together by infusing a molten thermoplastic material along an interface and within a gap between the pair of sheets. The method also includes extrusion welding the pair of sheets to a bottom sheet by infusing the molten thermoplastic material along and between the pair of sheets and the bottom sheet.
Claims25
A method of providing a liner or lining for a tank, the method comprising:
- positioning a pair of sheets adjacent each other to form a gap therebetween;
- extrusion welding the pair of sheets together by infusing a molten thermoplastic material along an interface and within the gap between the pair of sheets;
- positioning the pair of sheets adjacent a bottom sheet to form a gap between the pair of sheets adjacent and the bottom sheet;
- extrusion welding the pair of sheets to the bottom sheet by infusing the molten thermoplastic material along an interface and within the gap between the pair of sheets and the bottom sheet;
- and
- positioning the pair of sheets and the bottom sheet within a tank;
- wherein another gap is adjacent at least one wall of the tank and at least one of the bottom sheet and a sheet of the pair of sheets, and wherein extrusion weld material is infused within said another gap and penetrates to the at least one wall of the tank.
A lining for a tank, comprising a bottom sheet and a plurality of side sheets, the plurality of side sheets configured such that a gap is between a pair of adjacent side sheets of the plurality of side sheets, the pair of adjacent side sheets joined by an extrusion weld infused within the gap and along an interface between the pair of adjacent side sheets, wherein the lining defines an internal volume usable for storage of materials and wherein the pair of adjacent side sheets are joined by the extrusion weld without a filler rod in the gap therebetween, wherein the gap is a first gap, wherein a second gap is adjacent at least one wall of the tank and at least one of the bottom sheet and a side sheet of the pair of adjacent side sheets, and wherein extrusion weld material is infused within the second gap and penetrates to the at least one wall of the tank.
A tank comprising a lining that comprises a bottom sheet and a plurality of side sheets, the plurality of side sheets configured such that a gap is between a pair of adjacent side sheets of the plurality of side sheets, the pair of adjacent side sheets joined by an extrusion weld infused within the gap and along an interface between the pair of adjacent side sheets, wherein the lining defines an internal volume usable for storage of materials, wherein the pair of adjacent side sheets are joined by the extrusion weld without a filler rod in the gap therebetween, wherein the gap is a first gap, wherein the tank includes a wall having a second gap adjacent at least one of the bottom sheet and a side sheet of the pair of adjacent side sheets, and wherein the at least one of the bottom sheet and the side sheet of the pair of adjacent side sheets is joined to the wall by an extrusion weld infused within the second gap of the wall.
A tank comprising a plurality of surfaces and a liner having a bottom sheet and a plurality of side sheets, the plurality of side sheets configured such that a gap is between a pair of adjacent side sheets of the plurality of side sheets, the pair of adjacent side sheets joined by an extrusion weld infused within the gap and along an interface between the pair of adjacent side sheets, wherein the bottom sheet is joined to the pair of adjacent side sheets by an extrusion weld within a gap between and along an interface between the bottom sheet and the pair of adjacent side sheets, wherein the pair of adjacent side sheets are joined by the extrusion weld without a filler rod in the gap therebetween, wherein the bottom sheet is joined to the pair of adjacent side sheets by the extrusion weld without a filler rod in the gap therebetween, wherein another gap is adjacent at least one surface of the plurality of surfaces of the tank and at least one of the bottom sheet and a side sheet of the pair of adjacent side sheets, and wherein extrusion weld material is infused within said another gap and penetrates to the at least one surface of the tank.
