For use in highly corrosive gas and liquid
processes the GraphiTech line is available in three configurations, including
the GraphiTech Monoblock (GTM), the GraphiTech Monoblock with Vacuum Support
(GTMV) and the GraphiTech Inverted (GTI). GraphiTech discs are all constructed
using corrosive resistant, resin-impregnated graphite, and include non-asbestos
inlet and outlet gaskets. The GTM is available for general applications that
require a rupture disc to withstand corrosive chemicals, such as processes
involving sulfuric or hydrochloric acid, ultrapure water and phosgene. The GTMV
is designed for the same corrosive processes that need vacuum protection, which
can be required on any ASME vessel. The GTI’s inverted disc is engineered for
jobs requiring a high burst pressure, and also provides additional corrosive
protection with its available Teflon liner. GraphiTech discs’ flat design
allows them to fit securely in between piping flanges with no holders required
for installation. With a 0% manufacturing range and 90% operating ratio, discs
are stamped at their requested burst pressure and temperature. All models are
available in sizes from 1” through 24”, with ASME UD stamps available.
