Eminyakeni yamuva nje, njengoba amaphrojekthi wobunjiniyela bamazwe ngamazwe abeke izidingo eziphakeme ekulawuleni izinga kanye nokwamukelwa kokuthotshelwa kwemithetho, ukuthengwa kwensimbi phesheya kwezilwandle kudlulele ngale kokuqhathaniswa kwamanani alula. Abathengi manje bahlola abahlinzeki ngokusekelwe kumazinga, izitifiketi, amamaki ezinto ezibonakalayo, amandla okucubungula, nokuthembeka kokulethwa. Kosonkontileka be-EPC baphesheya kwezilwandle, abakhiqizi besakhiwo sensimbi, abahwebi, nabakhiqizi bemishini, insimbi yokuhlonza ethobelana nezindinganiso zasendaweni zobunjiniyela isibe yisici esibalulekile ekuqinisekiseni ukulethwa kwephrojekthi okushelelayo.

Imikhiqizo yensimbi ejwayelekile yangaphandle ivamise ukubandakanya amasistimu amaningi, afaka amazinga e-EN, ASTM, GOST, JIS, AS, kanye ne-BS. Lawa mazinga ahluka ngobukhulu, ukwakheka kwamakhemikhali, amandla esivuno, amandla aqinile, ukusebenza komthelela, izindlela zokuhlola, nezimfuneko zesitifiketi. Ngaphandle kobuchwepheshe obanele, abahlinzeki bangase babangele ukushintshwa kwezinto okunganembile, ukungaqondi kahle izidingo zokudweba, noma imibhalo yokwamukela engaphelele.

Ngenxa yalokho, abahlinzeki bensimbi abanamakhono osekelo lwezobuchwepheshe bamazwe ngamazwe bathola ukunakwa okwengeziwe kumakhasimende aphesheya. Izinkampani ezinjalo azihlinzeki nje ngemishayo ye-H, imishayo, iziteshi, ama-engeli, amapuleti ensimbi, amapayipi ensimbi, imigoqo eyindilinga, i-rebar, flanges, neminye imikhiqizo, kodwa futhi zihlinzeka ngokuqhathanisa okubonakalayo, ukuhumusha okujwayelekile, ukukhethwa kokucaciswa, nokusekelwa kwesitifiketi okusekelwe emidwebeni yamakhasimende, amazinga wephrojekthi, kanye nezidingo zokuhlola.

Ngokombono we-supply chain, iziteshi ezizinzile ezinikezela ngempahla eqondile ezivela ezigayweni zensimbi kanye nohlu olujwayelekile lwamabala nakho kube yizinto ezibalulekile ezithinta ukusebenza kahle kokuthengwa kwempahla kwamanye amazwe. Kumaphrojekthi aphesheya kwezilwandle anamashejuli okwakha aqinile, ikhono lomphakeli lokufanisa ngokushesha imininingwane, ukusika okuphelele, ukugoba, ukufakwa kwamagesi ashisayo, i-beveling, imvume yenkambiso, ukubhukha ngemikhumbi, kanye nokuhanjiswa kwemingcele kuthinta ngqo ishejuli yokulethwa kwezinto.

Ukuhlaziywa kwemboni kuphakamisa ukuthi imakethe yensimbi ejwayelekile yangaphandle iyathuthuka isuka ekuphakeleni komkhiqizo iye kumasevisi ochungechunge lokuhlinzeka ngobuchwepheshe. Ngokuzayo, abahlinzeki besevisi yensimbi abanolwazi oluqinile olujwayelekile, ukuphathwa kwezitifiketi, ukwesekwa kokucubungula, namandla okulethwa komhlaba jikelele bazoba ozakwethu ababalulekile ekuthengweni kobunjiniyela baphesheya kwezilwandle.
