Examination of these discs will indicate that each of these discs is domed. This dome was produced at the factory by taking the individual disc to 70% of its burst pressure.<\/p>\n<p>The ASME as well as other pressure vessel codes dictate that pressure vessels must be equipped with a rupture disc designed to burst no higher than the design pressure of the vessel. For pressure loads that do not cycle rapidly such as our vessels, Fike suggests limiting the actual operating pressure to no more than 90% of its burst pressure. This combination will limit operating pressures to no more than 90% of the design pressure of the vessel.<\/p>\n<p><strong>We have selected Alloy 600 as the standard material for these rupture discs.<\/strong>\u00a0It provides excellent corrosion resistance while retaining over 90% of its room temperature rating at temperatures up to 500 \u00b0C. For added corrosion resistance we can furnish these discs with gold facing or replace with discs made of Alloy C276. Discs can be produced to match any operating pressure and temperature above the stated minimums.<\/p>\n<p>Parr reactors and pressure vessels from 25 mL to 2000 mL use the 526HC Series Alloy 600 disc or 581HC Series Alloy 600 with gold facing. The 1 gallon and larger use the 708HC Series discs. The 4580 Reactor Systems use the 1415HC Series discs.<\/p>\n<p>In general, the 500 psi disc in the 526HC Series discs and the 600 psi in the 708HC Series are the lowest available ranges in the Alloy 600 material. Alternate disc materials are available but they do not offer the same corrosion resistant properties and temperature capabilities.<\/p>\n<p>For applications where users prefer a lower range pressure gage, we would add a spring loaded relief valve set to protect the gage and a 1000 psi rupture disc as the fail safe protection.<\/p>\n<p>Users are invited to contact the Parr Technical Support Staff with requirements for special rupture discs.
