Marina piping

A marina piping comprising:

• a primary pipe chemically compatible and impervious to fluids to be transmitted therethrough;
• a flexible secondary pipe within which the primary pipe is carried;
• a flexible conduit resistant to mechanical stresses, the conduit adapted to surround the flexible secondary pipe, the flexible conduit comprising a metallic core and thermoplastic jacket surrounding the metallic core;
• an insulating layer comprising a silica needle mat material surrounding the secondary pipe;
• and
• a metallized polyester film surrounding the silica needle mat, wherein the metallized polyester film is disposed between the silica needle mat and the metallic core of the flexible conduit.

A mulit-layered piping system for transporting a fluid from one location to another, the pipe comprising:

• a primary pipe having a interior surface in contact with the fluid;
• a secondary pipe surrounding an outer surface of the primary pipe, the secondary pipe having a plurality of flanges projecting radially inward, the flanges and the outer surface of the primary pipe defining a plurality of passages for transporting the fluid axially along a length of the piping system in the event a leak occurs in the primary pipe;
• a fire resistant insulating layer comprising a silica needle mat surrounding the secondary pipe;
• and
• a first sheet of metallized polyester surrounding the insulating layer.
