Izinga lensimbi ye-alloy efana ne-SA-213 T5, T9, ne-T22 ivame ukucaciselwa amandla ayo ekushiseni okuphezulu nokumelana nokugqwala.

9. Kungaba isikhathi esingakanani ipayipi lomshini wokushisa elinomfutho ophezulu lingasebenza ngaphansi kwezimo ezijwayelekile zokusebenza?

Ubude besikhathi sokusebenza buhluka kakhulu ngokuya ngezinga lezinto ezisetshenziswayo, izinga lokushisa elisebenzayo, ukushintshashintsha komfutho, indawo yokugqwala, namakhemikhali amanzi. Ngokukhetha okufanele kwezinto, ukwelashwa kwamanzi, nokunakekelwa, amapayipi ensimbi ekhabhoni angahlala iminyaka engu-15–25, kuyilapho amapayipi ensimbi engxubevange athuthukile ezitshalweni ezinomfutho ophezulu kakhulu engadlula iminyaka engu-30. Ukulawulwa kwekhwalithi okuqinile kwe-Wuxi Hengzhihui kusiza ukukhulisa ubude besikhathi sokusebenza.

10. Ngingayicela kanjani isilinganiso sezindleko noma ngixoxe nochwepheshe mayelana namapayipi omshini wokushisa anomfutho ophezulu?
