Abstract
A penetration fitting for forming a sealed connection between a conduit and a containment structure in an underground storage tank fueling system is provided that includes a main fitting element for forming a sealed connection to each of the conduit and the containment structure, wherein the main fitting element includes an interstitial space that is in fluid communication with each of the conduit and the containment structure. In one embodiment a monitoring fluid is disposed in the interstitial space and a sensor is used to monitor the level of the monitoring fluid.
Claims36
A penetration assembly for forming a sealed connection between a conduit and a containment sump in an underground storage tank fueling system, the penetration assembly comprising:
- a main fitting element for forming a sealed connection to each of the conduit and the containment sump, the main fitting element including an interstitial space that is in fluid communication with an interstitial space in each of the conduit and the containment sump.
An underground storage tank fueling system comprising:
- a product pipeline comprising a primary pipeline, a secondary pipeline and a product pipeline interstitial space extending therebetween;
- a containment sump having an inner wall, an outer wall and a containment sump interstitial space extending therebetween;
- and
- a penetration fitting forming a sealed connection with the conduit and the containment sump to sealingly connect the conduit to the containment sump, wherein the penetration fitting comprises a penetration fitting interstitial space that is in fluid communication with each of the product pipeline interstitial space and the containment sump interstitial space, forming a contiguous interstitial pathway between the product pipeline interstitial space and the containment sump interstitial space.
A method for detecting leaks in an underground storage tank fueling system comprising:
- providing a product pipeline comprising a primary pipeline, a secondary pipeline and a product pipeline interstitial space extending therebetween;
- providing a containment sump having an inner wall, an outer wall and a containment sump interstitial space extending therebetween;
- and
- sealingly connecting a penetration fitting to the conduit and to the containment sump to sealingly connect the conduit to the containment sump;
- forming an interstitial space in the penetration fitting that is in fluid communication with each of the product pipeline interstitial space and the containment sump interstitial space, forming a contiguous interstitial pathway between the product pipeline interstitial space and the containment sump interstitial space.
