HOSE BURST SUPPRESSION SLEEVE SYSTEM
A protective suppression system including one or more sleeves of expansion coil of energy-absorbing material wrapped around a hose and a blanket which can be wrapped loosely around the wrapped hose. The longitudinal edges of the blanket fasten together to form a protective cylindrical tube, and can be joined end-to-end with one or more additional blankets to extend the protective tube to a desired total length. The system thus can provide improved safety to personnel and the environment by shielding a hose under pressure to suppress bursts, block leaks and by redirecting or channeling test fluids and cleaning fluids.
1 . A burst suppression system comprising a first expansion coil and a blanket;
said expansion coil comprising a helical strip comprising an energy-absorbing material adapted in dimensions to helically sheath a length of hose to be contained; and said blanket comprising:
an impervious flexible sheet of fabric-reinforced material adapted to coil into a cylindrical tube around said wrapped length of hose and having two opposing cord-reinforced longitudinal edges; and a longitudinal fastener system adapted to retain the coiled shape of said cylindrical tube.
2 . The burst suppression system of claim 1 wherein said helical strip comprises a thermoplastic material.
3 . The burst suppression system of claim 1 wherein said helical strip comprises polyurethane.
4 . The burst suppression system of claim 1 further comprising a second expansion coil applied over said first expansion coil.
5 . The burst suppression system of claim 4 wherein said longitudinal edges of the coiled blanket overlap significantly when fastened.
6 . The burst suppression system of claim 5 further comprising an end fastener system adapted so that two or more of the blankets can be joined together end-to-end to make a longer blanket.
7 . A hose burst suppression system comprising a length of hose with a fitting on each end, an expansion coil helically wrapped around the length of hose between said fittings, and a blanket adapted to coil into a cylindrical tube around said helically wrapped hose.
8 . The system of claim 7 wherein said blanket extends past each end of said coil and partially over said fittings.
9 . The system of claim 7 further comprising a second expansion coil helically wrapped around the first expansion coil.
10 . A method of protecting a hose assembly comprising:
helically wrapping a first length of expansion coil around a length of hose assembly comprising a hose and a fitting on each end of said hose, said coil extending from one said fitting to the other; and
wrapping a blanket loosely around the helically wrapped hose;
overlapping the longitudinal edges of said blanket; and
fastening the wrapped blanket securely.
11 . The method of claim 10 further comprising helically wrapping a second length of expansion coil around said first length of expansion coil.
