1, mu chikhalidwe si zotsatira ndondomeko kuwotcherera chitoliro, ayenera kukhala oyenera kuonjezera osungidwa kutalika, epoxy ufa mapeto a polyethylene wosanjikiza akhoza kupewedwa chifukwa cha chitsulo chitoliro mulu kwa nthawi yaitali, chitoliro zitsulo dzimbiri chifukwa kwambiri 3 PE anticorrosive imakhala yokhotakhota m'mphepete.

2, Anticorrosive chitoliro kwa nthawi yaitali, waikamo panja adzakhala ataphimbidwa chitoliro, kuteteza kukokoloka kwa mvula, kuchititsa dzimbiri chitoliro mapeto.

3, Ngati payipi munda yomanga mkombero ndi yaitali, akhoza besmear maburashi weldable odana dzimbiri utoto chubu alibe zitsulo, kuteteza dzimbiri chitoliro chifukwa dzimbiri posungira 3 Pe ❖ ❖ kuyanika kukhala zokhota m'mphepete.

Kupitilira 4, kuwongolera kolimba kwa machubu kumapeto kosungidwa mu weld akupera ndi apamwamba kwambiri.Polyethylene mu kuwotcherera otsetsereka malo ogulitsira ndi ena onse chitoliro thupi, kupanga epoxy ufa wosungidwa kutalika > 20 mm, pofuna kupewa welds epoxy ufa pansi pa dzimbiri chifukwa choyamba 3 Pe anticorrosion wosanjikiza kukhala zokhota m'mphepete.
