5. Ukugqiba umphezulu
Kukho iindlela zokwambathisa okanye unyango lokulwa nomhlwa ukuze kwandiswe ubomi emanzini olwandle.
6. Ukusika kunye nokwenza ngokwezifiso
Iinqwaba zamaphepha zinqunyulwa ngobude, ukucubungula okungakumbi kungenziwa ukuba iprojekthi yakho iyayifuna loo nto.
7. Uhlolo loMgangatho
Ukwakheka kweekhemikhali, iipropati zoomatshini kunye nobukhulu kuvavanywa ngokungqongqo kwaye i-MTC iyabonelelwa.
Umphezulu weNqwaba yePhepha leNsimbi ye-ASTM A690
Amazwe aseMelika:HDG njenge-ASTM A123 (uboya obuncinci be-zinc ≥ 85 µm); Uboya be-3PE abunyanzelekanga; zonke iziphelo ziyahambelana ne-RoHS.
Mzantsi-mpuma weAsia:Ubukhulu be-hot dip galvanized yi-hollyh (ngaphezulu kwe-100μm), kwaye kufakwa iileya ezimbini ze-epoxy coal tar coating, ingatshizwa ngetyuwa ivavanywe iiyure ezingama-5000 ngaphandle kokugqwala, yeyona ilungileyo ekusetyenzisweni kwendalo yaselwandle eshushu.
ISICELO
1. Inqwaba yentsimbi yokwakha izibuko: Isicelo sokwakhiwa kodonga lwezibuko, idokhi kunye ne-quay, amandla amangalisayo okuxhasa ulwakhiwo kunye nobomi benkonzo obuhlala ixesha elide kwindawo yolwandle.
2. Inqwaba yeNsimbi yoKhuselo loMlambo: Yenzelwe ukuqinisa iziseko zonxweme lomlambo, ukunyanga ukukhukuliseka komhlaba kunye nokukhusela kwimpembelelo yokuhamba komlambo kunye nezikhukula zomlambo.
3. Inqwaba yentsimbi yesiseko seBridge: Ifanelekile ukusetyenziswa ekwakheni isiseko sebhulorho ukuze kufunyanwe isiseko esinzulu kunye nozinzo lwesakhiwo phantsi kobunzima besakhiwo.
4. Inqwaba yentsimbi engaphantsi komhlaba: Isetyenziswa kwiindawo ezingaphantsi komhlaba, kwiitonela nakwizakhiwo ezingaphantsi komhlaba ukuze kugcinwe umhlaba ngendlela ethembekileyo kwaye kuxhaswe ukumba.
Kutheni Ukhetha Intsimbi Yasebukhosini YaseTshayina Yeenqwaba Zeeshiti Zensimbi
1. Amaxabiso ngqo eFektri – Gcina iindleko eziyi-10–20%
Sifumana izinto ngqo kwiifektri zethu kwaye sisebenzisana nezinye iifektri ezikwindawo yethu, nto leyo ethetha ukuba akukho mntu uphakathi kwaye amaxabiso angcono kakhulu angaphaya kwalawo anikezelwa ngababoneleli basekuhlaleni.
2. Uluhlu oluqinileyo – Iitoni ezili-1000+ ezilungele ukufumaneka
Isitokhwe esikhulu seenqwaba zamaphepha ezilinganayo senza kube lula ukuba sihlangabezane neemfuno zabathengi ngokukhawuleza kwiiprojekthi ezingxamisekileyo kwaye sinciphise ixesha lokulinda.
3. Ukuhanjiswa Okukhawulezileyo – Iintsuku ezisi-7–15 kwihlabathi liphela
Ulungiselelo oluhle lwemveliso kunye nokuhanjiswa kwezinto ezisemgangathweni kusenza sithumele ngokukhawuleza emva kokufumana intlawulo kuzo zonke iizibuko zaseMzantsi-mpuma Asia, eMbindi Mpuma, naseMelika.
4. Ulawulo oluqinileyo loMgangatho kunye neSatifikethi
Siqhuba uvavanyo olupheleleyo malunga nokwakheka kweekhemikhali, iimpawu zoomatshini kunye nobukhulu, kwaye i-MTC ikhutshwa kwi-odolo nganye.
5.Ubuchule bokwenza ngokwezifiso
Imveliso ingalungiswa ngokweebude ezenziwe ngokwezifiso (6m–18m), iiprofayili (U/Z/Larssen) kunye nokugqitywa komphezulu, (ukupenda ukusetyenziswa elwandle).
6. Inkonzo yoThumelo lweeNgcali
Sineqela elinobuchule nelinamava ukukuxhasa ngenkqubo yokubhala amaxwebhu, ukupakisha, ukulayisha kunye nokuthumela ukuze ukonwabele ukususwa kwempahla ngendlela ethe tye kunye nokuhanjiswa kwayo ngexesha elifanelekileyo.
