BLAST RESISTANT PIPE PROTECTION SYSTEM AND METHOD
The present invention is directed to generally to protection of structures from explosives, and specifically to a blast resistant pipe protection system and method for using same. The present invention is directed to a system and method for protecting a pipe. In some embodiments, the present invention is directed to a system for protecting a pipe, comprising an energy absorbing inner matrix bound to the pipe; an outer wrap comprising fire resistant foil; and a blast resistant material disposed between the inner matrix and the outer wrap, wherein the blast resistant material comprises Purlite. In some embodiments, the present invention is directed to a method for protecting a pipe comprises binding an energy absorbing inner matrix to the pipe; disposing Purlite around the inner matrix; and wrapping the Purlite with fire resistant foil.

an outer wrap comprising fire resistant foil; and
a blast resistant material disposed between the inner matrix and the outer wrap, wherein the blast resistant material comprises Purlite.
2 . The system for protecting a pipe according to claim 1 , wherein the Purlite is contained in a plurality of bags.
3 . The system for protecting a pipe according to claim 1 , wherein the bags are arrayed circumferentially around the pipe.
4 . The system for protecting a pipe according to claim 1 , wherein the system is resistant to at least about 50 pounds of TNT at about 10 feet distance.
5 . The system for protecting a pipe according to claim 1 , wherein the energy absorbing inner matrix comprises:
a polymeric annulus; and
a pair of fiberglass half-pipes disposed over the annulus.
6 . The system for protecting a pipe according to claim 5 , wherein the polymeric annulus comprises first and second polymers.
7 . The system for protecting a pipe according to claim 6 , wherein the first polymer comprises urethane foam.
8 . The system for protecting a pipe according to claim 6 , wherein the second polymer comprises reticulated foam.
9 . The system for protecting a pipe according to claim 6 , wherein the annulus comprises an inner annulus comprising the first polymer and a second annulus comprising the second polymer.
10 . The system for protecting a pipe according to claim 9 , wherein the second annulus further comprises a third polymer soaked into the second polymer.
11 . The system for protecting a pipe according to claim 10 , wherein the first polymer comprises urethane foam, the second polymer comprises reticulated foam, and the third polymer comprises urethane.
12 . The system for protecting a pipe according to claim 1 , wherein the inner matrix comprises a blast resistant window film.
13 . The system for protecting a pipe according to claim 1 , wherein the inner matrix comprises ballistic film.
14 . The system for protecting a pipe according to claim 1 , wherein the inner matrix comprises steel wire.
15 . The system for protecting a pipe according to claim 1 , wherein the inner matrix comprises a clamp.
16 . A system for protecting a pipe, comprising:
an energy absorbing inner matrix bound to the pipe, wherein the energy absorbing inner matrix comprises:
a first annulus comprising urethane foam;
a second annulus disposed around the first annulus, the second annulus comprising reticulating foamed soaked in urethane;
a pair of fiberglass half-pipes disposed over the second annulus;
a blast resistant window film disposed over the half-pipes;
a ballistic film disposed over the blast resistant window film;
steel wire disposed over the ballistic film; and
a clamp;
an outer wrap comprising fire resistant foil; and
a blast resistant material disposed between the inner matrix and the outer wrap, wherein the blast resistant material comprises a Purlite contained in a plurality of bags arranged circumferentially around the pipe,
wherein the system is resistant to at least about 50 pounds of TNT at about 10 feet distance.
17 . A method for protecting a pipe, comprising:
binding an energy absorbing inner matrix to the pipe;
disposing Purlite around the inner matrix;
wrapping the Purlite with fire resistant foil.
18 . The method for protecting a pipe according to claim 17 , wherein the disposing comprises:
providing the Purlite in a plurality of bags.
19 . The method for protecting a pipe according to claim 18 , wherein the providing comprises arranging the bags circumferentially around the pipe.
20 . The method for protecting a pipe according to claim 17 , wherein the method provides protection of the pipe from at least about 50 pounds of TNT at about 10 feet distance.
