| A surge
resistant rupture disk (bursting disc) for railroad took cars and over-the-road trailer
service Industry.
The disk
is designed for direct installation on to standard threaded or bolted type
tank car fittings.
- Available in standard AAR burst ratings.
- Resists overpressure surges of 125% to 140% of the disk"s rated
burst pressure.
- Simple Installation
- Accurate
- Superior Cycle life under pressure cycling conditions

Performance
The
SR-TC rupture disk (bursting disc) will resist overpressure surges* of 125% to 140% of the
rated burst pressure for up to 0.5 seconds duration. Greater surge
protection may be expected for shorter surge duration. The SR-TC rupture
disk offers extended disk service life where the disk may be subjected to
'humping" action or when rapid deceleration of an OTR trailer occurs.*The
value of the over pressure surge depends on the disk's burst pressure
rating.
Installation
The
SR-TC rupture disk (bursting disc) may be installed directly on to standard threaded or
bolted type tank car fittings.
Construction
The
slotted top section is protected by a tank car ring which also ensures
burst accuracy. A vacuum support prevents damage to the disk, should the
disk be subjected to vacuum during unloading or while the tank car is in
transit. A spacer ring is located above the FEP/P'TFE seal and the top
section.
Materials
