Abstract: A T-fitting such as for use inside a containment box for connecting a primary pipeline to a gasoline dispenser has two flanges which connect to the pipeline and a main T-element sealed to each flange by a sealing element such as a gasket. The flanges thread onto each end of the primary pipeline. The main T-element has a stem which is threaded to a pipe leading to a gasoline dispenser. The flanges of the T-element are bolted to the main body of the T-element with the rubber gasket in between to seal the primary pipeline to the T-element. A method for installing a secondary containment system using the T-fitting includes the steps of fastening the stem of the T to the pipe leading to the gasoline dispenser, fastening the flanges of the T-fitting to primary pipeline segments, and fastening the flanges to the main body of the T element.

Abstract: A flexible penetration fitting is provided for sealing the hole through which a pipeline penetrates a wall of an underground containment box. The penetration fitting includes a flexible boot with a sealing flange for providing a first seal against the inside wall of the box. The sealing flange is held against the wall by a backing ring placed against the outside wall of the box. The backing ring includes a plurality of studs extending through the wall and into the box. A compression ring with a plurality of holes is placed over the sealing flange with the studs of the backing ring extending though the holes. A plurality of nuts are threaded to the studs to hold the sealing flange firmly against the inside wall of the box. The flexible boot also includes a sleeve for providing a second seal against the outside surface of the pipeline. The sleeve is stepped with different sized openings so as to be able to receive different sizes of pipelines.

Abstract: A pipe layout system for secondary containment includes alternating deep and shallow penetration holes in containment boxes installed below gasoline dispensers, and a double-walled pipeline inclined downward from each shallow box to an adjacent deep box. Each deep box has a fitting which closes the end of the secondary piping within the containment box. These fittings have apertures positioned to face downward and communicating with a conduit which leads to a sensor mechanism at the low point of the conduit. If there is leaking gasoline within the secondary pipes, it will flow to the deep box, through the hole, and down to the sensor. A small amount of gasoline is all that is necessary to trip the sensor and shut down the primary product pipeline. In the shallow boxes, the same fitting is used to close the ends of the secondary piping, and the aperture therein is preferably positioned upward.

Abstract: A secondary containment system is provided for use in preventing leakage to or from an underground storage tank at a joint where a riser line connects to the tank.

The sealing ring has a sleeve for sealing against the outer wall of the secondary sealing tube and a flexible bell-shaped skirt for sealing against the outer wall of the storage tank. A support bracket clamps to the outer wall of the riser line and includes three arms extending radially outward. The three arms engage the secondary riser tube to hold it into engagement with the sealing ring and thereby hold the sealing ring in sealing engagement with the tank wall by maintaining a downward force on the secondary riser tube.

Abstract: A fire protective collar for plastic fittings used in flammable fluid handling equipment is formed in two pieces which fit together around the fitting. Each piece has a semicircular top with a cutout for fitting around a pipe, and semicircular walls for fitting around the fitting. At the ends of each wall is a flange with a hole so that the two pieces can be removably fixed together by bolts and wing nuts. The collar may be used in a system where a containment box for collecting leaking gasoline from gasoline handling equipment, such as a gasoline dispenser, is disposed below the dispenser. The box receives a gasoline supply pipe passing through an aperture, and a fitting is provided for sealing the aperture and adjustably fixing the supply pipe. The fitting includes a main body, a deformable element, a seating piece for seating the deformable element and threaded to the main body, and a clamping piece threadable onto the seating piece to cam the deformable element radially inward to contact the supply pipe.
