Abstract: The present invention relates to an apparatus and method for handling liquids or gases. In particular, the present invention relates to a double walled apparatus having interwoven fibers between the inner and outer walls of the pipe. The invention may also include sensors in the apparatus. The apparatus comprises a first wall designed to contain a liquid or a gas, a second wall designed to contain any liquid or gas that penetrates the first wall, and interwoven fibers coupled between the first and second wall. The interwoven fibers are preferably resin laminated fibers in a matrix configuration. The apparatus may also comprises a sensor and a wire embedded in the apparatus either in the first wall, the interwoven fibers, or the second wall. The first wall is preferably comprised of three layers that are cohesively bonded together.
