    摘要: A safety system for a fluid conduit includes an elongated flexible conduit having a first end and a second end and a central opening running therethrough and capable of transporting a first fluid under pressure. A first valve is located near the first end of the conduit and a second valve is located near the second end of the conduit. Each of the valves is moveable between a closed position and an open position so as to control the flow of the first fluid through the conduit. The central opening of the conduit is surrounded by a conduit wall which extends substantially the entire length of the conduit. A plurality of enclosed channels are located within the conduit wall and extend at least a substantial length of the conduit. A second fluid under pressure is contained in the channels and a sensor is provided for monitoring the pressure of the second fluid within the channels. One or both of the valves are operatively associated with the second fluid and close when the monitored pressure falls below a predetermined level.

    摘要: A dual-containment pipe includes a primary pipe and a secondary pipe having an inner peripheral surface that radially supports an outer peripheral surface of the primary pipe with an interstice formed therebetween. The secondary pipe contains fluoropolymer. The primary pipe has a mono-layered structure of static dissipative fluoropolymer, a multi-layered structure with static dissipative fluoropolymer at its innermost layer, or a multi-layered structure with static dissipative PA at its innermost layer and a fluoropolymer layer.

    摘要: Split fittings for use in the installation of a semi-rigid secondary pipe over a primary pipe comprise a pair of housing halves which, when mated, form a housing enclosure, sealing means and clamping means capable of holding the secondary pipe and housing halves as a sealed enclosure. A method of fitting a rigid pipeline system with secondary containment system with a secondary semi-rigid pipe uses the split fittings.

    摘要: A valve (10) has a body (11) provided with two separate but parallel flow passages therethrough. A first diaphragm assembly (14) is held between a lower bonnet (12) and the body, and is movable toward and away from a seat (48). A second diaphragm assembly (15) is held between an upper bonnet (13) and the body. A follower (16) is arranged between the diaphragms. An actuator (20) is arranged to cause substantially parallel motion of the diaphragms in response to movement of the actuator.

    摘要: A pipeline system is provided for a pumping system for fluid products, such as gasoline, diesel fuel and chemicals, and including a pump for pumping such products from a storage tank through through the primary pipeline of the pipeline system to a product dispenser. The pipeline system includes a secondary containment system for the primary pipeline between the tank and dispenser which includes telescoping pipe sections of different diameters. The telescoping piping is installed around the primary pipeline and the pipe sections are, prior to final installation, movable between intermediate and final positions, for enabling completion, testing and inspection of the primary pipeline prior to final completion of the secondary containment system. A fusion welding wire bond is provided between overlapping portions of the telescoping pipe sections for bonding these sections in the final positions thereof. An air test clamp assembly enables air pressure testing of the secondary containment system.

    摘要: A double-containment thermoplastic pipe assembly is provided to prevent against potentially hazardous spills or leaks of chemicals and the like. The double-containment pipe assembly comprises a containment pipe and at least one carrier pipe disposed therein. The carrier pipe is retained in spaced relationship to the containment pipe by support clips with outwardly extending radially aligned legs. Restraint couplings may be disposed at selected locations along the double-containment pipe assembly. The restraint couplings include a carrier portion, a containment portion and a connecting portion extending therebetween. Double-containment pipe fittings also are provided to ensure complete double-containment protection throughout an entire double-containment pipe assembly.

    摘要: A service connection between a water main and a meter within a building has a service conduit within a leakage conduit. The leakage conduit has a sealed connection with a casing sealed to the main and enclosing a corporation stop to which the service conduit is connected. The leakage conduit is sealed to the service conduit within the building and adjacent the meter and includes an outlet extending outwardly through the building wall above the ground so that leakage within the corporation casing or a leak in the service conduit may be quickly detected. In the event of a leak, the service conduit may be removed and replaced through the leakage conduit with excavation limited to exposing the corporation casing and the end of the leakage conduit connected thereto. A snake provided with a flexible wedge that includes connections with an existing service conduit and a leakage conduit to be installed enables the former to be withdrawn and the latter simultaneously to be pulled through the ground to effect its installation. The flexible wedge may be double ended with a cable connected to each end.
