Amapayipi ensimbi ahlanganisiwe ayisikwele nangunxande e-Tianjin Yuantai Derun Group anikezwe isitifiketi somkhiqizo we-AAAAA yi-Institute of Metallurgical Industry Planning.

I-TianjinI-Yuantai DerunIqembu lihlanganiswe ngesikwele nesingunxandeamapayipi ensimbibanikezwe isitifiketi somkhiqizo we-AAAAA yi-Institute of Metallurgical Industry Planning.

Ngokwezidingo ezithile "zokuqinisekisa ukuthi uqinisekile" ngamapayipi ahlanganisiwe ayisikwele nangunxande ngezinjongo zesakhiwo, amapayipi ensimbi ayisikwele nangunxande ngezinjongo zesakhiwo ezijwayelekile, indinganiso icabangela ngokuphelele ukuhambisana kwekhwalithi, impendulo yekhwalithi, isitifiketi somkhiqizo, imiklomelo yokuhlonipha ezingeni lomkhiqizo, ikhono lokuqinisekisa ikhwalithi ezingeni lebhizinisi, ikhono lokusungula izinto ezintsha, ubuqotho bebhizinisi, izinga lenkonzo, izinga lolwazi nokunye okuqukethwe. Igxile ekudlulisweni kwekhono lokuqinisekisa ikhwalithi yomkhiqizo webhizinisi kanye nenani lomkhiqizo womkhiqizo, ithuthukise amazinga okuhlola esayensi, anengqondo, athuthukile futhi asebenzayo, inikeze isisekelo sesinyathelo esilandelayo sepayipi elihlanganisiwe elinenhloso yesakhiwo, isitifiketi somkhiqizo esiqinisekisiwe sepayipi lensimbi elihlanganisiwe elibandayo noma elihlanganisiwe elishisayo, ukukhulisa nokwakha imikhiqizo yensimbi "umkhiqizo oqinisekisiwe".
