Armor
Armor is recommended for all graphite disks for added safety, easier installation and
elimination of breakage during installation. Armor reduces the possibility of a premature
burst due to uneven or excessive
torqueing of the flange studs.
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 304/316 Stainless
Steel as an option.
Disks for Immediate Shipment
In order to provide the best possible service, BS&B stocks monobloc disks in the following
sizes: 25, 40, 50, 80, 100, 150 and 200 mm (1”, 1.5”, 2”, 3”, 4”, 6”, 8”).
Stocked Burst Pressures:
10-15-20-25-30-40-50-75-100-125-150 psig
All disks must be for 150 ANSI flange ratings.
Flange Ratings
Saf-T-Graf disks can be supplied to fit flange ratings ANSI, DIN, JIS, BS, AFNOR etc.
Please specify flange rating when ordering
Gaskets
BS&B Safety Systems, L.L.C. stocks gaskets in the materials below:
� Garlock ® or Klinger ® -Sil (standard)
Optional Materials:
� GRAFOIL ®
� Neoprene
� PTFE solid
Please specify your gasket material when ordering.
Sensors
A GAS TM (Graphite Alert Sensor) is available to provide warning of a burst graphite disk
Installations
The Saf-T-Grafdisk is designed to permit direct installation between ANSI,DIN,JIS,
BS, AFNOR pipe flanges and to locate between the flange bolts.
Operating Ratio
Up to 80% operating pressure to burst pressure ratio in a static environment. Lower
operating ratios can be expected in a cyclic environment.
