A marina pipe includes a flexible conduit resistant to mechanical stresses, the conduit adapted to surround the secondarily contained flexible piping. The conduit comprises a metallic core and a thermoplastic jacket. The secondarily contained flexible piping comprises an inner supply pipe, wherein the inner pipe is comprised of a first, inner layer fabricated from nylon, a second, intermediate layer comprising a nylon reinforced wrap, and a third, outer layer comprising a polyethylene material, the nylon inner material, the nylon wrap and the polyethylene outer layer being extruded simultaneously to form the inner pipe. The secondarily contained flexible piping further comprises a flexible outer secondary containment pipe within which the inner supply pipe is carried, the outer pipe being fabricated from a fuel impervious material and having a plurality of radially projecting flanges disposed between the inner supply pipe and the outer secondary containment pipe, to provide a locking engagement of the pipes with respect to each other and to provide for a flow passage between the pipes. Adjacent to the outer flanged pipe is a fire resistant silica needle mat layer.

Marina piping

A sump has a one-piece body, comprising a hollow base member for collecting fluids leaking from a piping system, the base member having an upper portion and a lower portion. The one-piece body further comprises a hollow riser section having an upper portion defining an opening, and a lower portion, the riser lower portion extending upwardly from the base member upper portion, the riser section having sidewalls with a generally corrugated shaped cross section in an axial direction. The hollow base member has a bottom and sidewalls, each of the bottom and sidewalls having an outer surface. The base member is fiberglass encapsulated, which encapsulation comprises a fiberglass woven reinforcement pad layer disposed on the base member bottom outer surface; a chopped fiberglass material layer disposed on the sidewalls outer surface up to and including an area abutting the riser section lower portion; a polymeric coating material layer disposed on the fiberglass woven reinforcement pad layer and the chopped fiberglass material layer; and a polymeric sealant material layer disposed on a portion of the riser section lower portion and on a portion of the polymeric coating material layer, at the area abutting the riser section lower portion. The sump further comprises a lid and a mechanism for mounting the lid to the riser section upper portion in a water resistant manner.
