Materials and Features
- Non-rotating double-cone plug design avoids galling and
scoring of safety head or connection during installation.
Reduces likelihood of leakage.
- Interchangeable hold-down rings permit use of several different
sizes and types of rupture discs in a single safety head.
Accommodates discs with rupture pressures as low as 90 psi
(6.2 bar) and ranging to 60000 psi (4137 bar) and above.
- Installs in any standard Autoclave coupling, elbow, cross
- Cold-worked Type 316 SS body hold down gland and plug,
- Hold down rings are corrosion resistant stainless steel.
Consult Local Sales Representative for safety head assemblies rated above 60000 psi (4137 bar).
To order an Autoclave Universal Safety Head, use the catalog
order number from table. ADD THE SIZE OF THE RUPTURE
DISC YOU WANT AS A SUFFIX TO THE CATALOG NUMBER;
SUCH AS CS6600-1/4A. Then order desired rupture discs
from rupture disc section. (This is important since the disc
size determines which hold-down ring will be furnished with
the safety head.) Note: Plug is included.
Note: Interchangeable hold-down rings permit use of several different sizes and types of rupture
disc in a single safety head.
Maximum pressure rating is based on the lowest rating of any component.
Actual working pressure may be determined by tubing pressure rating, if lower.
All dimensions for reference only and subject to change.
