Multi-walled pipes and storage tanks for toxic and corrosive fluids
A multi-walled vessel is described having improved circumferential and axial strength for transporting and storing fluids, comprising; (a) a first containment wall comprised of chopped fiberglass and continuous fiberglass strands secured to each other by polyester resin, said first wall having a thickness of from about 0.300 inches to about 0.330 inches; (b) a highly chemically resistant barrier on the inner surface of said first containment wall; (c) a plurality of substantially circumferential support ribs integrally bonded to said first containment wall; (d) said support ribs having feet of about 2.0 inches each in length by means of which said support ribs become integrally bonded to said first containment wall; (e) a first layer of closed cell foam located between said first containment wall and the inside surfaces of said support ribs; a second containment wall comprised of chopped fiberglass and continuous fiberglass strands secured to each other by polyester resin, said second wall having a thickness of from about 0.250 inches to about 0.300 inches; (g) said second containment wall having no undulations; (h) said second containment wall being integrally bonded to the top of said support ribs; (i) a second layer of closed cell foam located in the interstitial space between said first containment wall, said second containment wall and the outside surfaces of said support ribs; and said second layer of closed cell foam being level with the top of said support ribs.
