a. Nzira yekubvisa oxidation inotsanangurwa seinotevera: FF: Simbi yakafa zvizere ine zvinhu zvinosunga nitrogen muhuwandu hwakakwana kuti isunge nitrogen iripo (semuenzaniso 0,020% yeAl yose kana 0,015% yeAl inonyungudika). b. Kukosha kwakanyanya kwenitrogen hakushandi kana makemikari ari muchikamu ichi achiratidza huwandu hweAl hushoma hwe0,020% nechiyero cheAl/N che2:1, kana kana paine zvimwe zvinhu zveN-binding zvakakwana. Zvinhu zveN-binding zvinofanira kunyorwa muGwaro reKuongorora.

Kuedzwa kweHydrostatic

Kureba kwepaipi imwe neimwe kunofanira kuyedzwa nemugadziri kusvika pakumanikidzwa kwemvura kuchaita kuti pamadziro epaipi pave nekumanikidzwa kusingasviki 60% yesimba remubereko rakatarwa patembiricha yemumba. Kumanikidzwa kunofanira kutsanangurwa nemuenzaniso unotevera:

Kusiyana Kunobvumidzwa Muhuremu neMakuriro

Kureba kwepombi imwe neimwe kunofanira kuyerwa zvakasiyana uye huremu hwayo hahufanirwe kusiyana ne10% pamusoro kana 5.5% pasi pehuremu hwayo hwepfungwa, zvichiverengerwa uchishandisa hurefu hwayo nehuremu hwayo pahurefu hweyuniti imwe neimwe.
Dhayamita yekunze haifanirwe kusiyana kupfuura ±1% kubva padhayamita yekunze yakatarwa.
Ukobvu hwemadziro chero nguva hahufanirwe kupfuura 12.5% pasi peukobvu hwemadziro hwakatarwa
