Abstract
A secondary containment system for hazardous fluid conveyance and delivery systems. A plurality of rigid pipe envelope units is serially assembled to provide total containment for fluid pipes and associated pumping and fluid utilization components. Each pipe envelope unit has a containment shell and a mating upper cover. The containment shells are characterized by a concave surface portion, defined in transverse cross section by a substantially continuous curve. Each containment shell further has an upwardly facing, open top, extending the length of the shell and spanning the area between the upper ends of the concave surface. The upper cover for each envelope unit is coextensive with the open top of the shell, and is attached to respective upper ends of the concave surface, forming a fluid impervious seal between the mating surfaces. The pipe envelope units assume a variety of configurations to conform to the path of the fluid pipe. A leak sensor housing and special housings for components of the primary fluid system are also disclosed.
