Hom thiab kev siv ntawm cov hlau hauv PIPING kev lag luam
Raws li cov txheej txheem ntau lawm tau hloov pauv thiab ua kom nyuaj, kev xaiv ntawm cov neeg yuav khoom steel tau nce ntxiv kom tau raws li ntau yam kev xav tau hauv ntau yam kev lag luam.
Tab sis tsis yog txhua qib steel yog tib yam. Los ntawm kev txheeb xyuas cov hom hlau muaj los ntawm cov chaw tsim khoom siv yeeb nkab thiab nkag siab tias vim li cas qee cov hlau ua cov yeeb nkab zoo heev thiab lwm tus tsis ua, cov kws tshaj lij kev lag luam piping ua cov neeg yuav khoom zoo dua.
CARBON STEEL
Cov hlau no yog tsim los ntawm kev ntxiv cov hlau tsis muaj zog rau carbon. Cov pa roj carbon monoxide yog cov tshuaj lom neeg nyiam tshaj plaws rau cov khoom siv ferrous hauv kev lag luam niaj hnub no, tab sis cov ntsiab lus alloying ntawm txhua hom tau siv dav.
Hauv kev tsim cov kav dej, carbon steel tseem yog cov hlau nrov tshaj plaws. Ua tsaug rau nws lub zog thiab kev yooj yim ntawm kev ua, carbon steel yeeb nkab yog dav siv nyob rau hauv ntau lub teb. Vim tias nws muaj cov ntsiab lus alloying tsawg, carbon steel yeeb nkab yog tus nqi qis ntawm qhov qis qis.
Carbon steel structural kav yog siv nyob rau hauv cov kua tsheb thauj mus los, roj thiab roj, cov twj paj nruag, tsheb, tsheb, thiab lwm yam. Nyob rau hauv load, carbon steel kav tsis khoov los yog tawg thiab smoothly welded nyob rau hauv qib A500, A53, A106, A252.
ALLOY STEEL
Alloy steel muaj cov ntsiab lus ntawm cov ntsiab lus alloying. Feem ntau, cov khoom siv alloy ua rau cov hlau tiv taus kev ntxhov siab lossis cuam tshuam. Txawm hais tias npib tsib xee, molybdenum, chromium, silicon, manganese thiab tooj liab yog cov feem ntau alloying ntsiab, ntau lwm yam tseem siv nyob rau hauv steelmaking. Siv hauv kev tsim khoom, muaj ntau qhov sib xyaw ua ke ntawm cov alloys thiab cov concentrations, nrog rau txhua qhov kev sib xyaw ua ke tsim kom ua tiav cov txiaj ntsig sib txawv.
Alloy Steel Yeeb Nkab yog muaj nyob rau hauv qhov ntau thiab tsawg li ntawm 1/8′ txog 20′ thiab muaj sij hawm xws li S/20 rau S/XXS. Nyob rau hauv cov roj refineries, petrochemical nroj tsuag, tshuaj nroj tsuag, qab zib factories, thiab lwm yam., alloy steel kav kuj siv. Alloy steel kav yog txhim kho, tsim thiab muab khoom ntawm tus nqi tsim nyog raws li koj xav tau.
STAINLESS STEEL
Lo lus no yog me ntsis dab tuag. Tsis muaj qhov tshwj xeeb sib xyaw ntawm cov hlau thiab hlau alloy uas ua rau cov hlau tsis muaj steel. Hloov chaw, cov khoom ua los ntawm stainless hlau yuav tsis xeb.
Chromium, silicon, manganese, nickel thiab molybdenum tuaj yeem siv rau hauv cov hlau tsis muaj hlau. Txhawm rau sib txuas lus nrog cov pa oxygen hauv huab cua thiab dej, cov hlau no ua haujlwm ua ke sai sai ua ib zaj duab xis nyias tab sis muaj zog ntawm cov hlau kom tiv thaiv corrosion ntxiv.
Stainless Hlau Yeeb Nkab yog qhov kev xaiv zoo rau cov haujlwm uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb thiab yuav tsum muaj kev ua haujlwm siab xws li lub nkoj hluav taws xob, hluav taws xob, kev kho dej, kev siv tshuaj thiab roj thiab roj. Muaj nyob rau hauv 304/304L thiab 316/316L. Cov qub yog cov xeb-tiv taus thiab ruaj khov, thaum 314 L hom muaj cov ntsiab lus carbon tsawg thiab yog weldable.
