Description
The fully bolted holder consists of an inlet piece and an outlet piece with machined seating surfaces to form a gasket seal with 30° rupture discs.
We offer nine connection combinations of fully bolted holders. All are compatible with ASME, DIN, or JIS bolting classes and are available in any combination of inlet and outlet connections, which can be welded, threaded, or flat-faced.
Improve the corrosion resistance of your fully bolted holder by requesting a fluoropolymer coating for the inlet and/or outlet pieces.
LaMOT rupture discs and holders include permanent flow direction tags for easy visual verification of correct installation. Whenever specific holder identification tagging is required, the nameplate on the fully bolted holder will also include a stainless steel customer identification tag.
