A relief device for a high-pressure gas container, comprising a main body having a generally uniform outer circumference and that defines a primary bore, the primary bore in fluid communication with an interior volume of the high-pressure gas container, the main body having a secondary bore, the secondary bore located within the outer circumference and in fluid communication with the primary bore, a spud assembly seated in the secondary bore, the spud assembly including a rupture disc that relieves to the atmosphere the contents of the container when the container reaches a certain pressure, the rupture disc located within the secondary bore and within the outer circumference, the spud assembly and rupture disc fixedly attached. The relief device further includes a shear ring in communication with the rupture disc and a plug in communication with the spud assembly, the plug, when engaged with the spud assembly, forcibly engaging the shear ring against the rupture disc, wherein, when the rupture disc expands, the shear ring ruptures the rupture disc and the contents of the container relieve to the atmosphere through the plug.

1. A relief device for a high-pressure gas container, comprising: a main body having a generally uniform outer circumference and that defines a primary bore, the primary bore in fluid communication with an interior volume of the high-pressure gas container; the main body having a secondary bore, the secondary bore located within the outer circumference and in fluid communication with the primary bore; a spud assembly seated in the secondary bore, the spud assembly including a rupture disc that relieves to the atmosphere the contents of the container when the container reaches a certain pressure, the rupture disc located within the secondary bore and within the outer circumference, the spud assembly and rupture disc fixedly attached; a shear ring in communication with the rupture disc; and a plug in communication with the spud assembly, the plug, when engaged with the spud assembly, forcibly engaging the shear ring against the rupture disc; wherein, when the rupture disc expands, the shear ring ruptures the rupture disc and the contents of the container relieve to the atmosphere through the plug; and wherein the main body and spud assembly are welded. 2. The relief device of claim 1 wherein the rupture disc and spud assembly are welded.3. The relief device of claim 1 wherein the primary bore and the secondary bore are perpendicular.4. The relief device of claim 1 wherein the primary bore is concentric with the main axis of the relief device.5. The relief device of claim 1 wherein the secondary bore is perpendicular with the main axis of the relief device.6. The relief device of claim 1 wherein the plug is a non-vent plug.7. The relief device of claim 6 wherein the non-vent plug is filled with a fuse metal.8. A relief device for a high-pressure gas container, comprising: a main body having a generally uniform outer circumference and that defines a primary bore, the primary bore in fluid communication with an interior volume of the high-pressure gas container; a spud assembly seated in the primary bore, the spud assembly including a rupture disc that relieves to the atmosphere the contents of the container when said container reaches a certain pressure, said rupture disc located within the primary bore and within the outer circumference, the spud assembly and rupture disc fixedly attached; a shear ring in communication with the rupture disc; and a plug in communication with the spud assembly, the plug, when engaged with the spud assembly, forcibly engaging the shear ring against the rupture disc; wherein, when the rupture disc expands, the shear ring ruptures the rupture disc and the contents of the container relieve to the atmosphere through the plug; and wherein the main body and spud assembly are welded. 9. The relief device of claim 8 wherein the rupture disc and spud assembly are welded.10. The relief device of claim 8 wherein the primary bore is concentric with the main axis of the relief device.11. The relief device of claim 8 wherein the plug is a non-vent plug.12. The relief device of claim 11 wherein the non-vent plug is filled with a fuse metal.
