    Burst Tolerance

    Marked Burst Pressure Burst Tolerance
    < 1 psig (0.07 barg) -0/+0.75 psig (0/0.05 barg)
    1 – 15 psig (0.07 barg < 1.03 barg) ± 0.75 psig (0.05 barg)
    > 15 psig (1.03 barg) ± 5%
    For sizing, see the BS&B website or contact BS&B for appropriate KR

    Example: If a Saf-T-Graf IMB type disk is ordered with a 29 psig (2 bar) burst pressure, it will burst between 27.5 psig (1.9 bar) and 30.5 psig (2.1 bar). For reduced tolerances contact BS&B.

    Armored Option

    Armor is recommended for all graphite disks for added safety and elimination of breakage during installation. Armor consists of a steel ring encircling the outside diameter of the graphite rupture disk.

    Armor is standard on disks with burst pressures in excess of 150 psig or to fit ANSI Class 300 / 600 flanges. Carbon steel armor is standard with 300 series stainless steel as an option. Armor is recommended for applications where lateral blow out / loss of containment represents a safety concern.

    Armor for disks sizes shown when rated pressures equal to or exceed values in the below chart.
