Abstract
A laminous processed manway cover gasket includes an insert and a plurality of ePTFE layers of membranes wrapping the insert to result in isolation of the insert. In example, the isolation may result from a laminous, thermo-mechanical process that fuses together each ePTFE layer of membrane of the plurality of ePTFE layers of membranes.
Claims20
A gasket for a manway cover, the gasket comprising:
- a laminous seamless shell composed of a plurality of expanded Polytetrafluoroethylene membrane layers (ePTFE membrane layers) fused together in a laminous seamless form;
- and
- an insert material isolated in the laminous seamless shell.
A gasket for a manway cover, the gasket comprising:
- an insert made of a material;
- and
- a composition including a plurality of expanded Polytetrafluoroethylene (ePTFE) membrane layers isolating the insert in a seamless and laminous manner.
A method of manufacturing a gasket for a manway cover, the method comprising:
- forming a first set of membrane layers of ePTFE in a geometric shape;
- disposing an insert on a top layer of the first set of membrane layers of ePTFE;
- forming a second set of membrane layers of ePTFE on the insert and the first set of membrane layers of ePTFE, resulting in first shell with the insert;
- and
- applying a thermo-mechanical process to the first shell to fuse together each ePTFE membrane layer of the first set of membrane layers of ePTFE and the second set of membrane layers of ePTFE into a second shell in a laminous seamless form, resulting in a single-piece seamless isolation of the insert.
