ASTM A312 YEEBYog qhov feem ntau tau txais kev lees paub thoob ntiaj teb rau seamless, ncaj {{txias}} ua haujlwm welded useTenitic stainless hlau kav. Tsim thiab tswj hwm los ntawm Astm International, tus txheej txheem no txhais cov kev tsim kho kom haum thiab muaj kuab lom thiab kub thiab roj thiab roj av.
Nws lub luag haujlwm tseem ceeb yog kom ntseeg tau cov kav dej tau raws li cov khoom siv tau zoo me, thiab cov kws ua haujlwm muaj zog, muab cov khoom siv tshuab thiab cov khoom siv hluav taws xob nrog cov tshuab hluav taws xob tseem ceeb.
To taub aTM A312 Cov Chav Yeeb Yeeb
Tus qauv txheem npog cov ntau ntawm cov roj tsis muaj roj stainless hlau, txhua tus tau pom los ntawm nws cov lej sib koom tes (tsis tiav) kev tsim qauv. Cov qhab nia muaj xws li TPP300 / s304000), T316 / 31} {[{}}}}} Txoj Haujlwm Qib Siab zoo li TPP31 thiab Tp3Tag nrho.
Tsab ntawv "TP" sawv ntsug rau "Tube lossis cov yeeb nkab" thiab qhia cov khoom uas ua tau zoo {}} muaj cov kev pabcuam. Qhov kev xaiv ntawm qib yog nyob rau ntawm thaj chaw pabcuam - yam zoo li cov ntsiab lus, ntsuas kub}}}} - kev lag luam. Txhua qib yuav tsum ua raws li kev ua kom nruj li cov kev txwv tsis haum rau hauv tus qauv, txhawm rau qhia cov ntawv ceeb toom zeb zeb.
Qhov tseem ceeb tsim cov txheej txheemntawmASTM A312
Tus qauv txhais peb txoj kev tsim khoom lag luam rau kev tsim cov yeeb nkab: Welded, welded / li} welded plast - ua haujlwm. Seamless kav yog tsim los ntawm tho ib lub nplua nuj nqi, muab cov khoom sib txuam uas tsis muaj welded rau kev pabcuam siab tshaj plaws.
Welded kav pib li sawb / Skirl cov khoom (tsim tau rau hauv lub raj, thiab tom qab ntawd ua rau lawv muaj nqi ntev ntev. Kev ua txhaum loj, Welded kav rau cov kev pabcuam siab txuas ntxiv ua: hnyav txias- ua haujlwm kom txo lawv cov hlab sab sab nraud thiab / lossis phab ntsa thickness loj heev.
Qhov no txias ua haujlwm kho lub weld microstructure thiab txhim kho cov tshuab muaj zog dua rau kev sib piv rau cov kav dej seamless. Kev kho cua sov yog qhov yuav tsum tau ua rau txhua cov kav dej kom yaj cov qauv chromium, ua tiav cov khoom siv hauv kev ua haujlwm, ua tiav corrosion tsis kam, thiab ua tau raws li cov neeg kho tshuab neeg siv khoom.
Dagensional Yuav Tsum Tau Txais thiab thev
ASTM A312 Repreence Asme B36.19m rau cov qauv sab nraud diameters (NPS: Nominal cov yeeb nkab tsim (caij dav hlau zoo li 40s, 80s, lossis phab ntsa tuab). Tus qauv muab cov kev txwv tsis pub muaj nuj nqis uas cov tuam ntxhab yuav tsum ua raws li. Qhov no suav nrog kev sib txawv ntawm sab nraud lub cheeb (feem ntau ib puag ncig ± 1/8 txog 18), feem ntau yog {), feem ntau yog {) Cov hlua khi thev naus laus zis ntawm cov khoom siv sib txawv ntawm cov neeg tsim khoom sib xyaw thiab ua kom muaj kev txhim khu kev teeb tsa sib dhos lossis ua kom zoo dua ntawm cov kab spool, txo cov khoom kim heev.
Yuav tsum tau kuaj kev xeem thiab tshuaj xyuas kom ua
Yuav kom lav tau kev ua tau zoo, txhua tus xoos yeeb xaj rau astm A312 yuav tsum yauv roj teeb ntawm kev sim thiab tshuaj xyuas. Tensile kuaj xyuas cov yeeb nkab sib ntsib tsawg kawg nkaus zog zog (YS) thiab kawg tensile lub zog (UTS) cov ntaub ntawv thiab cov khoom lag luam. Flattening lossis khoov kuaj lossis flaring / hardness ntsuas kom muaj kev ua kom muaj kev ua kom muaj formability thiab weld suab.
Hydrostatic Kev kuaj lossis hluav taws xob kev ntsuas dhau ntawm cov yeeb nkab puv nkaus yog yuav tsum tau txheeb xyuas xau ntawm lub siab suav raws li phab ntsa tuab thiab khoom siv zog. Rau welded kav, tsis -) zoo li radecegraphy (RT) lossis kev ntsuas profile (UT) Txheeb xyuas cov khoom siv zoo (PMI) siv XRF analyzers los xyuas cov kev ua kom muaj txiaj ntsig zoo dua li qhov chaw kuaj xyuas ua ntej tso tawm cov khoom siv.
Cov ntawv thov ntawm ASTM A312 piping
Qhov tshwj xeeb ua ke ntawm corrosion tsis kam, lub zog ntawm qhov kub, thiab tswj kev tsim ua TTM A312 kav dej tsis tseem ceeb thoob plaws cov txheej txheem kev lag luam.
Lawv lis txhua yam los ntawm boiler pub dej ntawm siab pressures thiab kub rau cov acids heev li sulphuric lossis hydrochloric acid nyob rau hauv cov tshuaj rearsors.
Hauv cov khoom noj thiab dej haus ntoo, lawv txoj kev tu sab nraud tiv thaiv cov kab mob buildup thiab tiv taus cov neeg sawv cev.
Cov roj rov qab siv tau siv lawv hauv cov koog uas muaj cov dej khov kho corrosive.
Kws tsim khoom lag luam yuav tsum muaj lawv cov kev coj dawb huv thiab huv rau cov kab mob bioprocessing.
Hauv cov nroj tsuag hluav taws xob, lawv tseem ceeb heev li superheater thiab reheater tubing thiab chav dej. Offshore platforms cia siab rau lawv rau lub tshuab nqus dej hiav txwv thiab cov neeg ua haujlwm sab saum toj.
Qhov tseem ceeb, txhua qhov chaw mob siab rau cov kua ntshav, hloov siab heev, lossis cov yeeb nkab siab tshaj plaws rau kev tsim kev nyab xeeb thiab txhim khu kev qha piping networks.
Kev xaivASTM A312 YEEBqhia tias muaj kev cog lus rau qhov ua pov thawj ua tau zoo nyob rau hauv cov xwm txheej xav tau. Nws cov cai yuav tsum tau ua rau chemistry, kev ua tiav, qhov ntev, kev sim siab, sib sau tus caj qaum kev nyab xeeb thiab muaj txiaj ntsig kev nyab xeeb hauv ntiaj teb. Yeej ib txwm ua kom cov khoom siv traceability los ntawm kev lees paub
