Ulwakhiwo lweNsimbi yeZityalo zeMichiza

I-Steel Structure Chemical Plant yindawo yokwakha esemngciphekweni omkhulu ekufuneka ihambelane nemigangatho yoyilo engqongqo kunye neemfuno zokhuseleko. Njengeshishini eliphambili lomqolo kulo lonke ikhonkco loshishino lolwakhiwo lwePhondo laseShandong, i-EIHE Steel Structure (EHSS) ilawula ngokungqongqo ukhuseleko lwemveliso kunye nemigangatho, kwaye ngumenzi wakho othembekileyo wobuchwephesha obuphezulu.

Ingcaciso yeMveliso

I-Steel Structure Chemical Plant sisakhiwo esikhethekileyo ekufuneka sihambelane neemfuno ezikhethekileyo zokhuseleko ezifana nokumelana nokugqwala, ukukhuselwa kokuqhuma, ukukhuselwa komlilo kunye nokuthintela ukubola. Xa usenza iimveliso ezinjalo, umzi-mveliso wethu ulawula ngokungqongqo umgangatho wemveliso ukusuka ekukhethweni kwezinto eziphathekayo ukuya kwimveliso kunye nofakelo, ukuqinisekisa ukuthunyelwa ngokukhawuleza kunye nomgangatho okhuselekileyo weemveliso.

● Ukukhetha izinto ezingundoqo

Samkela intsimbi ephezulu edityaniswe nobuchwephesha bokunqanda ukubola ukwandisa ubomi benkonzo yeemveliso zethu.

✔ Izinto ezisisiseko:

- Kwiindawo eziqhelekileyo: i-Q235B okanye i-Q355B i-carbon structural steel ikhethiweyo.

- Kwindawo ezonakalisa kakhulu: iintsimbi zemozulu ezinje nge-Q355NH ziyakhethwa.

- Kumalungu anxibelelana ngokuthe ngqo nemidiya eyonakalisayo: i-316L okanye i-304 insimbi engenasici isetyenziswa ngokuqhelekileyo.

✔ Uyilo lweCandelo:

- Amacandelo avaliweyo okanye amacandelo e-solid-web abekwe phambili, kunye nolawulo olungqongqo phezu kobuncinci bodonga lodonga.

- Iziqendu zetsimbi ezinobumba ezibandayo zinqatshelwe ngokungqongqo kwizinto eziphambili zokuthwala umthwalo.

✔ I-Anti-corrosion Coating:

- Inkqubo yengubo ezintathu isetyenziswe: i-epoxy zinc-rich primer, i-epoxy micaceous iron oxide intermediate coat, kunye ne-polyurethane okanye i-fluorocarbon topcoat.

- Ubunzima befilimu eyomileyo iyonke abuyi kuba ngaphantsi kwe-200 μm.

● Inkqubo yeMveliso

Ulwakhiwo lweSteel Izityalo zeMichiza zisebenzisa iinkqubo ezingqongqo zokuvelisa ukuqinisekisa umgangatho wamacandelo anikezelweyo.
