180℃carbon steel khoov raws li ASME / ANSI B16.9
1, Cov khoom tseem ceeb muab tso rau thiab cov khoom zoo
180℃carbon steel khoov raws li ASME / ANSI B16.9, raws li qhov tseem ceeb ntawm kev sib txuas rau kev ua tiav 180℃tig hauv cov kav dej, tau dhau los ua cov khoom siv hauv kev lag luam vim qhov zoo ntawm cov khoom siv carbon steel. Nws siv siab -cov ntaub ntawv zoo carbon steel xws li Q235B, 20 # ASTM A234 WPB, uas sib xyaw ua ke siab - zog txhua yam khoom nrog kev ua haujlwm zoo heev - lub zog tawm los yog nce ntau dua 40% piv rau cov hlau zoo tib yam, thiab tuaj yeem tiv taus siab siab ntawm 35MPa. Nyob rau tib lub sijhawm, nws muaj kev ua haujlwm zoo vuam, ua kom yooj yim rau nruab thiab sib txuas cov kav dej ntawm qhov chaw. Los ntawm cov txheej txheem kho saum npoo xws li galvanizing, sandblasting, thiab dej-raws li cov xim pleev xim, cov khoom siv tiv thaiv corrosion kuj zoo dua, thiab nws cov kev pab cuam lub neej tuaj yeem ncav cuag 30-50 xyoo nyob rau hauv ib puag ncig nyuaj xws li av noo thiab sulfur-muaj xov xwm, zoo heev txo kev lag luam thiab tu nqi. Piv nrog rau cov ntaub ntawv xws li cov hlau tsis muaj steel, cov nqi tsim cov pa roj carbon steel bent kav yog qis dua, thiab cov ntaub ntawv tuaj yeem siv dua, uas tsis tsuas yog ua tau raws li kev xav tau ntawm kev lag luam, tab sis kuj siv cov tswv yim tiv thaiv ib puag ncig. Nws yog qhov kev xaiv zoo tshaj plaws uas sib npaug ntawm kev ua haujlwm thiab tus nqi. cov
2, Kub dabtsi yog khoov txheej txheem thiab meej specification tsim
Lub 180℃carbon steel khoov raws li ASME / ANSI B16.9 yog tsim los ntawm kev siv cov khoom kub siab tshaj (qhov nruab nrab zaus dabtsi yog khoov) tshuab, tsis tas yuav tsum tau cov yeeb nkab tsis muaj cov khoom siv raw. Nws yog ua tiav los ntawm lub tiaj los yog nthuav dav qhov chaw blanks, uas tsis tsuas yog simplifies cov txheej txheem txiav thiab ua kom txoj kev raug, tab sis kuj tsim cov khoom customized nrog txoj kab uas hla loj, nyias phab ntsa thiab thickness. Cov txheej txheem thev naus laus zis tau pom zoo nyob rau hauv: phab ntsa thickness uniformity yuam kev yog tswj nyob rau hauv ± 0.5%, thiab phab ntsa thickness txo tus nqi tsis tshaj 8%, deb superior rau kev lag luam qauv; Lub vojvoog curvature tuaj yeem hloov kho kom haum rau R=1D (luv vojvoog luv), R=1.5D (tus qauv vojvoog) rau R=3D (siab-} siab mob), nrog lub kaum ntse ntse ntawm ± 0.3%, kom ntseeg tau tias du thiab tsis muaj kev cuam tshuam cov kav dej xa mus. Cov kev qhia tshwj xeeb npog tag nrho ntawm DN15-DN2000, nrog cov phab ntsa tuab ntawm Sch5 txog Sch160. Nws yog sib xws nrog ntau lub teb chaws tus qauv xws li ASME B16.9 thiab GB / T27684-2011, thiab txhawb nqa ntau yam kev sib txuas xws li vuam thiab threading kom tau raws li qhov xav tau ntawm kev teeb tsa ntawm qhov sib txawv engineering scenarios. Thaum lub sij hawm tsim cov txheej txheem, tag nrho cov txheej txheem raug saib xyuas los ntawm 3D laser scanning, ua ke nrog kev tswj xyuas zoo xws li kev sim hydrostatic thiab kev kuaj tsis muaj kev puas tsuaj (NDT), kom ntseeg tau tias cov khoom tsis muaj xuab zeb qhov thiab cov kab nrib pleb, nrog rau vuam tsim nyog tus nqi txog li 99.8%. cov
3, Kev lag luam dav scenario adaptation thiab tseem ceeb qhov tseem ceeb
Daim ntawv thov ntawm 180℃carbon steel khoov raws li ASME / ANSI B16.9 khiav los ntawm tag nrho cov kev lag luam ntau lawm saw thiab tau dhau los ua ib qho khoom siv tseem ceeb hauv ntau qhov chaw tseem ceeb: hauv kev lag luam petrochemical, nws yog siv nyob rau hauv qhov rov qab ntawm siab - siab roj thiab roj xa mus kav dej thiab tuaj yeem tiv taus corrosive media xws li hydrogen sulfides. Phab ntsa thickness tsim nce 20% piv rau tus qauv tus nqi kom muaj kev nyab xeeb; Nyob rau hauv lub zog engineering, raws li ib tug tig point rau cable tais thaiv thiab supercritical chav tsev chav pipelines, nws muaj peev xwm tiv taus kub mus txog 620 degree, pab ua kom tiav cov kab layout thiab ruaj khov system; Hauv kev tsim kho thiab kev tsim vaj tsev hauv nroog, nws tsim nyog rau cov xwm txheej xws li kev txhawb nqa qhov, lub ru tsev bending beams, thiab cov khoom siv dej thiab cov kav dej. Los ntawm 180℃tig rov qab tsim, qhov chaw teeb tsa tau txais kev cawmdim thiab cov kav dej layout efficiency yog optimized; Tsis tas li ntawd, hauv kev lag luam xws li kev tsim khoom siv tshuab, kev sib txuas lus engineering, thiab kev lag luam tsheb, nws cov peev txheej hloov kho tau yooj yim thiab txhim khu kev qha kev ruaj ntseg zoo daws qhov teeb meem ntawm cov kav xa dej hauv qhov chaw txwv, txhim kho tag nrho cov txheej txheem kev ua haujlwm zoo. cov
4, Cov ntsiab lus ntawm cov khoom tseem ceeb sib tw
180℃carbon steel khoov raws li ASME / ANSI B16.9 muaj qhov zoo ntawm "cov khoom siv txhim khu kev qha, kev siv tshuab siab heev, thiab kev hloov pauv dav dav". Nws tsis tsuas yog muaj cov yam ntxwv ntawm lub zog siab, tus nqi qis, thiab kev ua haujlwm yooj yim ntawm cov ntaub ntawv carbon steel, tab sis kuj ua tiav ob qho kev txhim kho hauv qhov tseeb thiab kev ua tau zoo los ntawm kev siv tshuab kub bending. Los ntawm customized specifications rau scene adaptation, los ntawm kev tswj kom zoo mus rau ib puag ncig tus phooj ywg ntau lawm, cov khoom ua tau raws li cov kev cai nruj ntawm industrial pipeline systems rau tig Cheebtsam. Nws tsis tsuas yog txo cov nqi tsim kho, tab sis kuj txo qis kev txij nkawm los ntawm kev ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov, dhau los ua cov khoom siv zoo tshaj plaws rau cov haujlwm tseem ceeb hauv kev lag luam xws li tshuaj lom neeg, hluav taws xob, kev tsim kho, thiab lub zog, muab cov khoom lav rau kev nyab xeeb thiab ua haujlwm zoo ntawm cov kav dej. cov
