Ivalvu yebhabhathane ivavanywa ngeendlela ezininzi ukusuka ekuvelisweni ukuya ekuthunyelweni ukuqinisekisa umgangatho wayo kunye nokuthembeka kwayo. Uhlolo olupheleleyo lugubungela izinto ezisemgangathweni ezifana nezinto, ukugquma, inkangeleko, irabha, uxinzelelo, kunye nobukhulu, kunye nokusebenza kokuvala, inkangeleko, i-torque, ubulukhuni, ubukhulu, ukuhlanganiswa, ukuchaneka kwentambo kunye neflange, kunye neempawu zokulandelela.
Inkqubo yokuhlola ingenziwa ngolu hlobo lulandelayo: Ukuhlolwa kwezinto eziluhlaza → Ukuhlolwa kokucubungula → Uvavanyo lokusebenza kwemveliso olugqityiweyo → Ukwamkelwa kokugqibela. Inkalo nganye ichazwa kunye neendlela ezithile kunye nemigangatho.

Ukuqinisekisa ukuba i-corrosion iyamelana nokugqwala, ukunamathela, kunye nobukhulu be-coating kuhambelana nemigangatho.
4.2 Izinto zokuhlola
Unyango lwangaphambi kokucocwa komphezulu (ukususwa komhlwa) umgangatho ngaphambi kokutshiza (i-Sa2.5 okanye ngaphezulu, akukho bukhulu okanye umhlwa obonakalayo)
Ubukhulu bokugquma emva kokutshiza (kusetyenziswa igeyiji yobukhulu bokugquma)
Ukuncamathela kwengubo (uvavanyo olunqamlezileyo, isithuba se-1mm, indawo yokuxobula ingubo ≤5% emva kokususwa kwetheyiphu)
Ukuhlolwa kwenkangeleko (ukuwa, imingxunya yepin, amaqamza, ixolo leorenji, umahluko wombala)
