Steel Structure Chemical Plant

Steel Structure Chemical Plant yog ib qho chaw tsim khoom uas muaj kev pheej hmoo siab uas yuav tsum tau ua raws li cov qauv tsim nruj thiab kev nyab xeeb. Raws li lub tuam txhab ua lag luam nyob rau hauv tag nrho kev tsim kho kev lag luam saw ntawm Shandong xeev, EIHE Steel Structure (EHSS) nruj me ntsis tswj ntau lawm kev ruaj ntseg thiab cov qauv, thiab yog koj trustworthy high-tech steel qauv khoom chaw tsim tshuaj paus.

Product Description

Steel Structure Chemical Plant yog ib lub tsev tshwj xeeb uas yuav tsum tau ua raws li kev ruaj ntseg tshwj xeeb xws li kev tiv thaiv corrosion, kev tiv thaiv tawg, tiv thaiv hluav taws thiab kev tiv thaiv seepage. Thaum tsim cov khoom zoo li no, peb lub Hoobkas nruj me ntsis tswj cov khoom zoo los ntawm kev xaiv cov khoom siv rau kev tsim khoom thiab kev teeb tsa, kom ntseeg tau tias kev ua haujlwm sai thiab nyab xeeb ntawm cov khoom.

● Kev xaiv cov khoom tseem ceeb

Peb txais yuav high-strength steel ua ke nrog anti-corrosion technologies mus cuag cov kev pab cuam lub neej ntawm peb cov khoom.

✔ Khoom siv hauv paus:

- Rau qhov chaw dav dav: Q235B lossis Q355B carbon structural steel raug xaiv.

- Rau ib puag ncig muaj corrosive heev: huab cua steels xws li Q355NH nyiam dua.

- Rau qhov chaw hauv kev sib cuag ncaj qha nrog corrosive media: 316L lossis 304 stainless hlau feem ntau yog siv.

✔ Seem Tsim:

- Cov seem kaw los yog cov khoom-web seem yog qhov tseem ceeb, nrog kev tswj xyuas nruj me ntsis ntawm phab ntsa tuab.

- Txias-tsim nyias-walled steel seem yog nruj me ntsis txwv tsis pub rau thawj load-bearing Cheebtsam.

✔ Anti-corrosion Txheej:

- Cov txheej txheem peb txheej yog siv: epoxy zinc-nplua nuj primer, epoxy micaceous hlau oxide nruab nrab lub tsho, thiab polyurethane lossis fluorocarbon topcoat.

- Tag nrho cov zaj duab xis qhuav yuav tsum tsis pub tsawg tshaj 200 μm.

● Cov txheej txheem ntau lawm

Steel Structure Chemical Plants txais cov txheej txheem ntau lawm los xyuas kom meej qhov zoo ntawm cov khoom xa tuaj.
