First Claim
1. A pressure relief tool apparatus for a test cell, comprising:
- a plunger assembly;
a plunger rod;
a handle;
a stem;
a stem connector; and
a vent opening;
whereinsaid stem is connected to said plunger assembly;
said plunger rod is slidably retained within said plunger assembly and said stem;
said stem connector is adapted to connect said stem to a test cell;
said handle is operably connected to said plunger assembly;
said plunger rod is adapted to be slidably movable by manipulation of said handle; and
said vent opening is adapted to provide fluid flow from an annular opening intermediate an exterior surface of said plunger rod and an interior surface of said stem.

Abstract
A pressure relief tool including a stem connected to a plunger assembly, a plunger rod slidably retained in the plunger assembly and the stem, a stem connector for connecting the stem to a test cell vent opening, a handle operably connected to the plunger rod, and a vent tube extending from said plunger assembly, the vent tube fluidly connected to an annular opening within the stem. A method of opening a blockage and venting pressure from a high temperature high pressure test cell includes attaching a pressure relief tool of the present invention to the test cell vent opening; advancing the plunger rod through the vent opening, puncturing the blockage in the test cell to allow fluid flow to the vent opening, and allowing fluid to exit the test cell through the annular opening in the stem and the vent tube.

13. A method of venting pressure from a test cell, comprising:
-
fluidly connecting a pressure relief tool to a test cell; wherein said pressure relief tool comprises; a plunger rod; and a vent opening; and wherein said test cell; comprises a cell vent opening; and contains material disposed therein that prevents fluid flow through said cell vent opening; and operating said pressure relief tool to advance said plunger rod through said cell vent opening into said test cell to displace at least a portion of said material, thereby permitting fluid flow through said cell vent opening and through said vent opening. - View Dependent Claims (14, 15)
