Self-contained rupture disk cartridge

A self-contained rupture disk assembly for removable fluid-tight mounting in a fluid line connected to a pressurized container to establish a maximum pressure in said container by rupturing upon reaching a predetermined burst pressure, BP, said rupture disk assembly comprising:

• a cylindrical-shaped rupture disk holder having an outer side wall with a selected diameter and an orifice with a predetermined diameter, d, where d=BI/BP and BI=burst index;
• a polymer rupture device having a disk portion with a diameter substantially equal to said selected diameter and an outer skirt extending along said outer side wall of said rupture disk holder such that said polymer rupture device is supported by said rupture disk holder across at least said orifice, said polymer rupture device having a predetermined thickness, t, where t=BI/(BI/mil) thereby establishing said predetermined burst pressure, BP, in conjunction with the diameter, d, of said orifice in said rupture disk holder;
• and
• attachment means associated with said rupture disk holder for maintaining said rupture disk in fixed relationship over said orifice in said rupture disk holder so as to establish said predetermined burst pressure, BP, when mounted in said fluid line.

A self-contained rupture disk assembly for removable fluid-tight mounting in a fluid line connected to a pressurized container to establish a maximum pressure in said container by rupturing upon reaching a predetermined burst pressure, BP, said rupture disk assembly comprising:

• an annular ring having first and second sides and a selected thickness therebetween and further having an outer wall with a selected diameter and an orifice with a predetermined diameter, d, where d=BI/BP and BI=burst index, one of said first and second sides defining an annular recess;
• a polymer rupture disk supported by said annular ring across at least said orifice and having an outer skirt with a diameter greater than diameter of said annular recess and a predetermined thickness, t, where t=BI/(BI/mil) thereby establishing said predetermined burst pressure, BP, in conjunction with the diameter, d, of said orifice in said annular ring;
• and
• said polymer rupture disk in a press-fit engagement with said annular recess for maintaining said rupture disk in fixed relationship over said orifice in said annular ring so as to establish said predetermined burst pressure, BP, when mounted in said fluid line.

A self-contained rupture disk assembly for removable fluid-tight mounting in a fluid line connected to a pressurized container to establish a maximum pressure in said container by rupturing upon reaching a predetermined burst pressure, BP, said rupture disk assembly comprising:

• a cylindrical-shaped rupture disk holder having an outer side wall with a selected diameter and an opening with a predetermined diameter, d, where d=BI/BP and BI=burst index, said outer wall defining an annular recess encircling said cylindrical-shaped rupture disk holder;
• a polymer rupture device having a disk portion with a diameter substantially equal to said selected diameter and an outer skirt extending away from said disk portion and supported by said rupture disk holder across at least said opening and having a predetermined thickness, t, where t=BI/(BI/mil) thereby establishing said predetermined burst pressure, BP, in conjunction with the diameter, d, of said opening in said rupture disk holder;
• and
• a locking ring for engaging said outer skirt of said polymer rupture device in said annular recess to secure said polymer rupture device to said rupture disk holder in a fluid-tight relationship when said rupture disk assembly is placed in said fluid line.

A self-contained rupture disk assembly for removable fluid-tight mounting in a fluid line connected to a pressurized container to establish a maximum pressure in said container by rupturing upon reaching a predetermined burst pressure, BP, said rupture disk assembly comprising:

• a single annular ring having an outer diameter and an orifice with a predetermined diameter, d, where d=BI/BP and BI=burst index;
• a polymer rupture disk having a predetermined thickness, t, and supported by said single annular ring such that said polymer rupture disk covers said orifice and has an outer skirt that extends beyond said outer diameter of said single annular ring, where t=BI/(BI/mil), thereby establishing said predetermined burst pressure, BP, in conjunction with the diameter, d, of said orifice;
• and
• a fastening device for a press-fit relationship with said outer diameter of said single annular ring so as to force and hold said skirt of said polymer rupture disk in a fixed relationship over said orifice in said single annular ring thereby forming a receptive disk assembly that can be inserted in a fluid line of a pressurized container to establish a predetermined burst pressure, BP, for said container.
