Abstract
A protective shield for a pressure vessel which includes a ductile member for absorbing kinetic energy released if the pressure vessel fails by a portion of the pressure vessel breaking-off and tending to fly away from the remainder of the pressure vessel; the ductile member or a portion thereof undergoing substantial deformation, but not breaking, when loaded by the portion of the pressure vessel which tends to fly-away when the pressure vessel fails.
Claims15
A protective shield for a pressure vessel, comprising:
- a ductile means for absorbing kinetic energy released if the pressure vessel fails by a portion of the pressure vessel breaking-off and tending to fly-away from the pressure vessel;
- said ductile means undergoing substantial deformation, but not breaking, when loaded by the portion of the pressure vessel tending to fly-away when the pressure vessel fails;
- and
- means for attaching said ductile means to said pressure vessel so that if said pressure vessel fails, said ductile means will be loaded by said portion of the pressure vessel breaking-off and tending to fly-away;
- said ductile means comprising a ductile arcuate segment of a strap, and said means for attaching said ductile means to said pressure vessel comprising a pair of rings, attached about opposite ends of the pressure vessel, and a pair of straight segments of said strap, each straight strap segment being connected to one of said rings and to an end of said ductile arcuate segment of said strap.

A protective shield for a pressure vessel, comprising:
- a plurality of elongated straps, extending along the axial length of the pressure vessel in circumferentially spaced apart relationship and made of a ductile material having an ultimate tensile strength of about 37 to 45 kg/mm.sup.2, a yield strength of about 20 to 24 kg/mm.sup.2 and an elongation of about 20 to 27%;
- each of said elongated straps including a plurality of alternating, straight segments and arcuate segments along its length;
- said arcuate segments being adapted to undergo substantial deformation, but not to break, when loaded by a portion of the pressure vessel breaking-off and tending to fly-away in an axial direction from the pressure vessel;
- and
- a pair of rings attached to the axial ends of the pressure vessel;
- the ends of said elongated straps being straight segments, attached to said rings;
- whereby, if the pressure vessel fails by a portion thereof tending to fly-away in an axial direction, said elongated straps and said arcuate segments thereof will be loaded by the portion of the pressure vessel tending to fly-away.
