1. Q: Hauv qab dab tsi kub yuav tsum ASTM A333 GR.1 steel yeeb nkab tsis siv?
A: AFTM A333 GR.1 steel yeeb nkab tau teev tseg kom muaj qhov tsawg kawg ntawm kev ua haujlwm tsawg kawg ntawm -45℃f (-45℃feem ntau yog siv raws li tus qauv tsim). Siv hauv qab cov ntawv pov thawj kub uas txwv tsis pub tshaj yog txwv tsis pub siv. Vim tias nws cov kev cuam tshuam nruj yog tseeb ntawm -45 degree, yog tias siv nyob rau hauv qis dua kev pheej hmoo, ua rau cov khoom siv puas tsis ua haujlwm thiab xwm txheej kev nyab xeeb.

A: Thaum lub sijhawm cia, nws yuav tsum muab tso rau ntawm cov chaw qhuav, txhawb nqa los ntawm cov ntoo ntoo, thiab kev tiv thaiv los ntawm kev sib chwv dej ntev nrog av thiab dej kom tiv thaiv corrosion. Lub kaus mom yas yuav tsum tau muab ntsia ntawm cov yeeb nkab xaus los tiv thaiv cov teeb meem txawv teb chaws thiab noo noo ntawm kev nkag mus rau cov yeeb nkab. Thaum ho hoisting, siv cov nylon slings lossis tshwj xeeb clams kom tsis txhob ncaj qha cov hlua khi, uas tuaj yeem ua rau saum npoo kev puas tsuaj thiab khawb. Cov txuj ci no tuaj yeem dhau los ua kev ntxhov siab cov ntsiab lus. Thaum vuam nyob rau hauv cov cheeb tsam txias, noj cua sov thiab cua sov-}}} insulating ntsuas kub yuav tsis poob qis dua qhov xav tau, thiab nruj me ntsis ua raws li cov txheej txheem preheating.
3. Q: Yog tias qhov kev tsim qauv ntsuas kub yog qis dua -45 degree, cov khoom siv twg yuav tsum tau siv hloov chaw A333 GR.1?
A: Yog tias qhov kev tsim qauv ntsuas kub yog hauv qab - 45 degree, tsawg-kub steel yeeb nkab uas muaj ntau dua nruj heev yuav tsum tau xaiv. Cov kev xaiv tshwj xeeb suav nrog cov qhab nia siab hauv Astm A333 tus qauv, ua haujlwm rau -100} (Funity} (Funity} (Funity} Degree), gr. 9} (serviceable muaj rau -19 degree), grate} (engecure} Qhov kev xaiv yog nyob ntawm qhov kub thiab kub thiab kev lag luam.
4. Q: Puas tuaj yeem AFTM A333 GR.1 Steel Yeeb Siv nyob rau hauv high {{}} kub kev pab?
A: Tsis tau. ASTM A333 GRISE tshwj xeeb tsim thiab muaj ntawv pov thawj rau tsawg- kev pab kub. Nws cov yam ntxwv txhua yam, tshwj xeeb yog nws lub zog thiab cov plhuav, tsis yog qhov zoo rau qhov siab- kub kev pab. Txog siab {- kub kev pab (piv txwv li, xws li {} (carromium {}} molybdenum alloy hlau). Kev siv tsis raug ntawm cov ntaub ntawv hauv high-}} Qhov chaw ib puag ncig muaj peev xwm ua tau kom tsis muaj zog, ntau dhau, uas ua rau muaj kev pheej hmoo tseem ceeb.
5. Q: Dab tsi yog cov ntaub ntawv tseem ceeb tshaj plaws thaum daws cov teeb meem technical ntsig txog Astm A333 Gr.1 Steel Yeeb Nkab?
A: Cov ntaub ntawv tseem ceeb tshaj plaws yog cov astm A333 / A333m txheem nws tus kheej, uas ua haujlwm ua qhov yuav tsum tau ua. Tom ntej no yog lub phiaj xwm tau txais cov piping tsim qauv tsim qauv, xws li ASME B31.3 (cov txheej txheem txheej txheem tsim) vuam, thiab kev tshuaj ntsuam cov kev xav tau. Tom ntej no yog vuam - tus qauv, xws li seem ib sab IX (vuam tsim nyog) thiab AWS D1.1. Thaum kawg, cov chaw tsim khoom lag luam cov ntaub ntawv xeem (MTR) thiab WPS) yog cov haujlwm ua haujlwm tseem ceeb uas coj cov haujlwm tshwj xeeb thiab pab kom muaj kev ntxhov siab.
