Hauv kev lag luam piping systems thoob plaws hauv petrochemical, hluav taws xob tsim, nkoj tsim, thiab chaw muag tshuaj, kev ntseeg tau thiab yooj yim ntawm kev saib xyuas ntawm flanged cov ntsiab lus txuas ncaj qha cuam tshuam rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm tag nrho cov chaw.Stainless hlau Stub Ends, tshwj xeeb cov yeeb nkab fittings siv nrog lub puab tsaig sib koom flanges, muab cov kev sib txuas zoo tshaj plaws rau cov raj xa dej uas yuav tsum tau nquag disassembly thiab tshuaj xyuas. Raws li tus kws tshaj lij ntawm cov yeeb nkab fittings,MIDASmuaj ntau yam ntawm stainless hlau stub xaus tsim nyob rau hauv nruj raws li thoob ntiaj teb cov qauv xws li ASME B16.9 thiab MSS SP-43, xa cov khoom zoo sib txuas rau cov khoom lag luam hwm thoob ntiaj teb.
1. Khoom txhais: Lub Core Adapter rau Lap Joint Flange Connections
Stainless hlau stub kawg yog ib tug luv luv yeeb nkab haum nrog ib tug flared kawg thiab ib tug beveled weld kawg, feem ntau yog siv nyob rau hauv ua ke nrog ib tug ncej puab flange. Thaum lub sij hawm installation, lub flared kawg mates nrog lub sealing lub ntsej muag ntawm lub puab tsaig flange, thaum lub weld kawg yog pob tw-welded rau cov yeeb nkab. Bolts dhau los ntawm lub puab tsaig flange thiab cov flange tawm tsam, compressing lub gasket kom ua tiav sealing. Lub ntsiab kom zoo dua ntawm qhov kev tsim no yog tias lub puab tsaig sib koom ua ke flange tuaj yeem tig tau ywj pheej nyob ib ncig ntawm lub qhov kawg, tso cai rau lub qhov ntsia hlau kom sib haum yam tsis hloov cov yeeb nkab nws tus kheej, ua kom yooj yim rau ntawm qhov chaw sib dhos.
Raws li qhov ntev ncaj, stub xaus yog cais rau hauvLong Stub EndsthiabShort Stub Ends. Cov hom ntev feem ntau ua raws li ASME B16.9, haum rau cov ntawv thov uas xav tau txuas txuas txuas; yam luv luv ua raws li MSS SP-43, muab qhov zoo ntawm qhov chaw txwv tsis pub muaj xwm txheej.
2. Cov txiaj ntsig tseem ceeb: Kev sib txuas yooj yim thiab kev lag luam zoo
Tus nqi tseem ceeb ntawm MIDASstainless hlau stub kawgcov khoom yog reflected nyob rau hauv cov nram qab no yam:
Ua ntej, hloov tau yooj yim sib dhos thiab yooj yim txij nkawm.Txij li thaum lub flange tsis ncaj qha welded rau cov yeeb nkab, lub puab tsaig sib koom flange tuaj yeem tig tau ywj pheej, tshem tawm qhov xav tau ntawm lub qhov ntsia hlau qhov kev sib raug zoo thaum lub sijhawm teeb tsa thiab txo qhov kev sib dhos nyuaj. Qhov tseem ceeb tshaj, thaum yuav tsum tau kuaj xyuas lossis hloov cov yeeb nkab seem, tsuas yog tshem cov bolts cais cov flanges yam tsis tau txiav cov yeeb nkab, muab kev yooj yim heev rau cov ntawv thov uas yuav tsum tau ntxuav thiab tshuaj xyuas.
Thib ob, qhov tseem ceeb ntawm cov khoom siv tus nqi optimization.Hauv cov kav dej siv cov khoom siv kim xws li duplex stainless hlau lossis npib tsib xee alloys, tsuas yog cov stub kawg-uas ncaj qha mus rau qhov nruab nrab-yuav tsum tau ua los ntawm cov hlau sib txawv, thaum lub puab tsaig flange tuaj yeem tsim los ntawm cov nqi qis dua. Cov ntaub ntawv kev lag luam qhia tau hais tias rau 10-nti Chav Kawm 300 kev sib txuas hauv Inconel 625, siv lub qhov kawg nrog cov pa roj carbon steel lap joint flange tuaj yeem txuag tau 45% -65% ntawm txhua qhov sib txuas flanged piv rau tag nrho-alloy weld caj dab flange.
Thib peb, zoo heev stainless hlau khoom kev ua tau zoo.MIDAS muaj ntau yam khoom siv, suav nrog 304/304L, 316/316L, 321, 904L, thiab duplex stainless hlau. 304/304L muab kev tiv thaiv corrosion zoo heev. Nyob rau tib lub sijhawm, 316/316L, muaj molybdenum, muaj qhov zoo tshaj pitting tsis kam nyob rau hauv ib puag ncig chloride, ua rau nws tsim nyog rau kev siv tshuaj lom neeg, tshuaj, thiab zaub mov ua haujlwm nrog kev ua kom huv thiab kev tiv thaiv corrosion.
3. Cov qauv thiab cov khoom Specifications
MIDASstainless hlau stub xausyog tsim nyob rau hauv nruj raws li thoob ntiaj teb cov qauv, feem ntau npog:
ASME B16.9: Siv rau qhov ntev ntev, qhov loj ntawm 1/2 "mus rau 24" (DN15-DN600)
MSS SP-43: Siv rau luv luv stub xaus, tshwj xeeb tshaj yog rau stainless hlau nyias-wall piping systems
ASTM A403 Cov khoom siv raw khoomCov khoom siv rau stainless hlau pob tw-weld fittings, npog cov qib xws li WP304, WP304L, WP316, thiab WP316L
Cov ntsiab lus tseem ceeb suav nrog cov yeeb nkab OD, txoj kab uas hla (G), lub vojvoog (R), lap thickness (t), thiab ncaj ntev (F). Lub puab tsaig thickness t yuav tsum tsis txhob tsawg tshaj li lub nominal yeeb nkab phab ntsa thickness, thiab sab nraum qab ntawm lub puab tsaig yuav tsum tau machined los xyuas kom meej kev sib raug zoo nrog lub ntsej muag flange.
