2. Inboard Leakage Test.
a. Release all loading pressure in cover
dome.
b. Pressurize inlet to 30 psig (2.1 Barg) with
air, GN
2
.
c. Tube outlet to a beaker of water to ob serve
number of escaping gas bubbles.
Inboard leakage path may be via plug/seat or
dynamic side seal.
3. Pressure Containment Test.
a. Pressurize inlet to 200 psig (13.8 Barg)
and outlet and cover dome to 150 psig
(10.3 Barg) with air or GN
2
.
b. Spray liquid lead detector and check all
ex ter nal leak points; i.e. plugged con nec-
tions, and fl ange bolting.
4. Excessive leakage will require disassembly,
examination of sealing elements, correction
