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% |
Example: If a Saf-T-Graf Plus 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.
Vacuum Support
For Vacuum support order as MBV or AMBV (armored support). Vacuum support is necessary under the following application conditions:- Burst pressure is below 22 psig (1.52 barg) and full vacuum may be present (-14.5 psi / -1 barg)
- Vacuum exceeds 30% of burst pressure. For example, a 10 psig (0.7 barg) burst pressure disk will experience a -3 psig (-0.2 barg) vacuum
- Cycling between vacuum conditions and positive pressure may occur and burst pressure is below 22 psig (1.52 barg)
- Vacuum supports are needed for disks rated below 22 psig (1.52 bar) and where a vacuum condition exists. Model MBV or AMBV vacuum supports are not required on 0.5 and 0.75 inch (15 and 20 mm) monobloc disks
- Temperature ranges -100º to 400ºF (-73º to 205ºC). For further clarification on when to use a vacuum support, consult factory

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.
