Abstract
A storage system for a petroleum product and related methods includes a vapor barrier including at least one layer having an ultra high molecular weight polyethylene material configured to inhibit absorption of a petroleum product therethrough. Such vapor barrier may be a coated fabric with the ultra high molecular weight polyethylene material and be configured to fluidly seal against a surface. The vapor barrier is further configured to be incorporated into any such storage system, which further includes a floating roof seal, a tank liner seal, and/or a leg boot seal.
Claims20
A storage system for a petroleum product, comprising:
- (a) a vapor barrier including at least one layer having a first ultra high molecular weight polyethylene film layer, a scrim layer, and a second ultra high molecular weight polyethylene film layer;
- wherein the scrim layer is secured to the first ultra high molecular weight polyethylene film layer and the second ultra high molecular weight polyethylene film layer such that the scrim layer is sandwiched between the first and second ultra high molecular weight polyethylene film layers,
- wherein the first ultra high molecular weight polyethylene film layer is configured to be received against a surface for fluidly sealing thereagainst, and
- wherein the second ultra high molecular weight polyethylene film layer is exposed and thereby configured to receive the petroleum product thereagainst such that the vapor barrier is configured to inhibit absorption of the petroleum product therethrough.

- and wherein the scrim layer is secured to the first ultra high molecular weight polyethylene film layer and the second ultra high molecular weight polyethylene film layer such that the scrim layer is sandwiched between the first and second ultra high molecular weight polyethylene film layers;
- and
- (b) a floating roof system having a first roof portion, wherein the vapor barrier is configured to envelop the first roof portion to inhibit the petroleum product from contacting to the first roof portion;
- wherein the first roof portion includes a foam member, and wherein the vapor barrier is configured to surround the foam member and fluidly seal the foam member from the petroleum product;
- and
- wherein the second ultra high molecular weight polyethylene film layer is an outermost layer of the vapor barrier.
