Anti-corrosion Steel Yeeb Nkab Supplier-GNEE
1. Kev xav tau thiab kev sim rau cov kav dej los tiv thaiv corrosion. Raws li qhov yuav tsum tau ua, cov tshuaj tiv thaiv corrosion rau tag nrho cov kav hlau thiab cov khoom siv steel hauv qhov project no yog cov xim tsis muaj tshuaj lom epoxy zinc-nplua nuj xim thiab epoxy thee pitch.
(1) Internal anti-corrosion yog non-toxic epoxy zinc-nplua nuj xim. Lus Cim: Thaum siv cov primer, nws yuav tsum tau siv nws tusyees tsis muaj qhov to; lub topcoat tuaj yeem siv tom qab primer qhuav. Cov yeeb nkab pleev xim los yog cov hlau tsis huv, cov hollows, wrinkles, thiab khawb ntawm cov xim pleev xim yuav tsum tau kho. Ua tib zoo saib kom tsis txhob ua rau cov txheej txheem tiv thaiv corrosion thaum thauj thiab nqa. Yog tias muaj kev puas tsuaj, nws yuav tsum tau muab rov qab rau lub sijhawm, txwv tsis pub lub installation yuav tsis raug tso cai. Thaum cov tshuaj tiv thaiv corrosion ntawm cov yeeb nkab sib txuas yog nqa tawm hauv cov yeeb nkab trench, cov av thiab cov kab dej ntawm cov khoom tiv thaiv corrosion yuav tsum raug tshem tawm; Thaum backfilling av, yuav tsum tau saib xyuas kom tsis txhob ua puas lub txheej tiv thaiv corrosion. Thaum tsim kho nyob rau hauv cov cheeb tsam uas muaj cua tsis zoo, cov khoom siv cua tshuab cua yuav tsum tau siv. Kev tsim vaj tsev qhib tsis pub muaj nag, daus, lossis huab cua pos huab.
(2) Kev tsim kho kom zoo thiab cov qauv tshuaj xyuas: Kev tshuaj xyuas qhov tshwm sim: Cov kav dej tiv thaiv corrosion yuav tsum tau tshuaj xyuas ib qho los ntawm ib qho. Qhov saum npoo yuav tsum du, qhia cov xim pleev xim rau xim, cov txheej yuav tsum zoo ib yam, tsis muaj wrinkles, hollows thiab clots. Cov ntaub fiberglass mesh ntawm cov txheej tiv thaiv corrosion yuav tsum tau ntim nrog dej. Lub ntsej muag pleev xim. Kev tshuaj xyuas thickness: Randomly kuaj 1 yeeb nkab tawm ntawm txhua 20 kav dej, thiab siv lub computerized film thickness gauge (MCH-2004J) los kuaj nws. Ntsuas tag nrho ntawm 3 ntu ntawm ob qho kawg thiab hauv nruab nrab ntawm txhua lub yeeb nkab, 4 nyob rau sab sauv, qis, sab laug, thiab sab xis ntawm txhua lub yeeb nkab. Lub thickness ntawm nyias me ntsis thiab nyias me ntsis yuav tsum tau raws li qhov yuav tsum tau ntawm anti-corrosion qib. Kev tshuaj xyuas cov xim zaj duab xis tawg lub zog: Siv JG-3 hom DC hluav taws xob hluav taws xob ntes los tshuaj xyuas txhua lub hauv paus. Tsis muaj dab tsi. Cov xim pleev xim qhuav siv yog 450μm, thiab qhov ntsuas hluav taws xob yog 2500-2800V.
(3) Pipeline anti-corrosion siv tshuab Pipeline pre-kho: siv phau ntawv thiab hluav taws xob cov cuab yeej tshem tawm xeb. Ntxuav tawm cov roj, plua plav, vuam slag, oxide nplai thiab xoob xeb ntawm qhov chaw tiv thaiv corrosion. Qhov saum npoo yuav tsum tau khaws cia qhuav, tsis muaj dej cim, thiab muaj cov xim hlau nplaum. Kev ceev tshem tawm xeb kom tau raws li Sa2.5 qib yuav tsum tau:
① Internal anti-corrosion: Siv cov xim tsis muaj tshuaj lom epoxy zinc-nplua nuj ntawm ob lub hauv paus thiab ob sab. Cov txheej txheem kev tsim kho tshwj xeeb yog: ua ntej siv ob txheej ntawm primer, tom qab ntawd siv ob txheej xim. Tom qab txhua txheej qhuav, thov txheej tom ntej. Thickness Tsis pub tsawg tshaj 2.5μm.
② Sab nrauv los tiv thaiv corrosion: Epoxy thee pitch siv plaub roj thiab peb daim ntaub. Cov kauj ruam kev tsim kho tshwj xeeb: ua ntej siv cov primer (tsis muaj xim), tos kom qhuav, tom qab ntawd siv cov primer, qhwv peb txheej ntawm iav ntaub, thiab siv ob txheej txheej xim. Tag nrho cov tuab ntawm cov xim tsis yog tsawg dua 200μm.
③Packing thiab kho cov tshuaj tiv thaiv corrosion. Cov txheej txheem txheej thiab cov ntaub ntawv siv los kho thiab kho qhov chaw yuav tsum zoo ib yam li cov yeeb nkab lub cev txheej. Kev kho yuav tsum tau ua tom qab lub pob tw welding thiab cov yeeb nkab saum npoo kub yog txias kom qis dua 50 degree.
