Aircraft Pressure Relief Valves Tested with Electrically Heated Pressure Tank
Aircraft Pressure Relief Valves Tested with Electrically Heated Pressure Tank
1 PagesA heavy-guage pressure tank was designed and built so that the pressure would drop no more than 4 psi in one hour. The tank was equipped with a pressure gauge mounted on the top. The valve to be tested was installed at bottom of tank. To heat the vessel uniformly, accurately and constantly during the test, temperature was maintained at 500° F. - Three pairs of Chromalox SE-2450 electric Strip Heaters were clamped 120° apart around the tank circumference to welded-on studs. Heaters were clamped tight to deliver heat uniformly over the entire length of the tank.
