3.0 CONTAINERANDVALVEPREPARATION

3.1 TestandInspection

PROINERTinertgascontainerswillnotbefilledwithoutre‐testingifmorethan10yearshaveelapsedsincethedateof

thelasttestandinspection.

WARNING: PROINERTcontainercontentsareunderhighpressure.Neverattempttofillthecontaineruntilthe

contentshavebeendischargedandthepressuregaugereads0.

CAUTION: Careshouldbetakenwhenhandlingvalvecomponentstoavoiddamageofanykind.

3.2 ValveInstallationProcedure

Theproceduredetailedbelowdescribesthestepsnecessarytoinstallanewvalvetoacylinder:

Visuallyinspectcylinderthreadsandchaseanyburrsordebrisusinga1"NGTtap.

Vacuumallcylinderspriortovalveinstallationtoremoveanydebris.

PreparethePROINERTvalvewiththreewrapsof¾"wide,high‐densityPTFE

threadsealtapeontothe1"NGTmalethread.Wrapthethreadswithtape

clockwisewhenviewedfromthevalveinlet.Compressthetapeagainstthe

threadssecurelybyhand.

Usingabrush,applyGasoilaSS‐16Soft‐Setthreadsealantontothetaped

portionofthread.Applyenoughthreadsealanttocoverthefirst2‐3threads

ofthevalve(Figure3.2‐1).

Threadthevalveintothecylinderhand‐tightandthentightentoa

torqueof166to207lbf‐ft(225to280N‐m).

NOTE: InstallthevalveonthecylinderimmediatelyaftertheGasoila

threadsealantisappliedontothePTFEtapetopreventtheGasoilathreadsealantfromsettingpriortothe

valvebeinginstalledonthecylinder.

Checkforpropervalveinstallationwiththecylinder/valveengaugementgauge.Usethegaugetocheckthe

gapbetweenthecylinderneckbossandtheshoulderabovethe1"NGTthread(Figure3.2‐2).

o Valveisproperlyinstalledifthe“max/no‐go”sideofthegaugecannotfitinthe

can.

o Valveisimproperlyinstalledifthe“max/no‐go”sideofthegaugecanfitinthegapORthe“min/go”
