Product Offerings
DTM
Composite disk consisting of a slotted metal top section and a metal or fluoropolymer seal for low burst pressure
BTM
Prebulged, solid metal rupture disk; system pressure is applied to the dished or concave side, subjecting disk metal to tension loading
AVTM
Flat rupture disk for atmospheric vessels and isolating outlet port of relief valves; ready gasketted with fiber gaskets; direct installation between companion flanges
XN85TM
Precision scored, high performance specially manufactured by forming the disk first and then scoring
XTTM
Advanced rupture disk performance with an ‘X’ shaped score pattern; Designed for non fragmentation; Excellent for relief valve isolation
XBTM
Non-fragmenting rupture disk opens along pre-weakened score lines offers a broader range of burst pressures than the XN
LCNTM
Low pressure rupture disk with flat composite metal design that withstands full vacuum
ITCTM
Scored tension loaded rupture disk assembly designed for protection of intermodal tank containers, conforming with the latest norms IMO, ADR, RID, US DOT, DOT
