The Shand & Jurs FRP 94063 Series Manhole Cover is designed to provide
emergency venting relief of low-pressure storage tanks and vessels. These covers also
provide quick, easy access for tank inspection and maintenance. When the tank is exposed
to abnormal internal pressure beyond the capability of the breather vent, the manhole
protects the tank against costly rupture.
The Shand & Jurs FRP 94063 Series Manhole
Cover provides an effective vapor-tight seal until pressure relief is required to protect
the tank. Under emergency fire conditions, the cover opens fully to allow escape of
vapors and prevents damage to the tank.
CONSTRUCTION
STANDARD: Flange, Seat, and Pallets
of Derakane 470 Vinyl Ester Resin. 316 SS Studs and Teflon Air Cushioned Pallet Seating.
CUSTOM: Other resins and hardware are available to meet exact corrosion requirements
including 411 Derakane, Furan, and Hastelloy.
FAST INSPECTION, EASY MAINTENANCE
Unit’s rugged and lightweight design provides for easy, convenient handling for installation,
inspection and maintenance. The pressure cover is normally restrained to allow automatic
reseating. Disconnection of the retaining cord allows the pressure vent cover to be
completely removed, thereby allowing access into the tank through the full diameter seat
opening. Facilitates tank inspection and repair procedures.
