Yog li, cov raj xa hluav taws xob yuav tsum tsim qauv thiab tsim nyob rau hauv ib txoj kev uas tuaj yeem ua rau cov kev nyuaj siab rau thaum lub sijhawm ua kua lossis tshuaj lom neeg. Qee lub chaw (cov nroj tsuag hluav taws xob, cov roj av ntxiv, thiab lwm yam) yuav tsum tau siv hluav taws xob ntev thiab nyhav ntxig. Ntxiv mus, cov chaw ntawm cov teeb meem siv teeb meem vim yog qhov chaw ua haujlwm tsawg.

Nrog rau qhov kom zoo dua no, tag nrho cov raj xa dej muaj txoj hauv kev muaj txiaj ntsig zoo rau lawv cov raj xa hluav taws xob thiab txo lawv txoj kev xav tau thiab sijhawm.

Luav tshib feem ntau yog siv rau kev hloov pauv ntawm qhov kev ntws. Cov lub luj tshib uas muaj hloov lub kaum sab xis ntawm ntws ntawm 180¡Ã, 90¡Ã lossis 45Ã. Lub 180¡u Saab System kuj tseem hu ua ¡®return bend¡¯. Lub luj tshib cov tshuab tuaj yeem faib ua ob pawg uas yog pob tw weld luj tshib thiab txo lub hwj. Taub qab-welded luj tshib yog qhov feem ntau thiab cov khoom xav tau.

cov neeg siv khoom siv tau. Peb kuj tseem tuaj yeem muab tshem tawm tau tso ua haujlwm tso ua haujlwm, suav nrog cov qauv ntawm cov raj xa dej txiav, bevelling, sib dhos thiab

Pipelines rau kev sib sau ua ke sour roj tau ua tiav nrog cov khoom (lossis clad) inconel? 625 alloy thiab siv nyob rau hauv dej hiav txwv sib pauv hluav taws xob hauv kev ua kom huv, cov nroj tsuag hluav taws xob, thiab offshore cov kev pab cuam sab saum toj uas feem ntau xav tau cov khoom no.

Kev tiv thaiv zoo li rau chlorine ion muaj kev cuam tshuam corrosion tawg. Ua rau pom txaus rau cov organic acids xws li acetic, formic thiab ncaj qha. Kev tiv thaiv zoo heev rau cov dej siab purity siv hauv thawj lub voj voog thiab theem nrab cov voj voog ntawm cov ntsuas kev siv hluav taws xob nuclearized nuclear.

Qhov sib koom ua ke yog tsim los ntawm bolting ob txoj kev pluag rau ib leeg thiab sib khi lawv los ntawm kev siv ntau gaskets. Flanges feem ntau yog ua los ntawm txhuas, tooj dag, tooj dag lossis cov hlau. Cov khoom nyiam tshaj plaws rau cov ntawv thov flange dav yog cov tshuaj pleev cov pa roj carbon hlau. Ntxiv mus, flanges tuaj yeem foiled sab hauv nrog sib txawv hom ntaub. Feem ntau, cov khoom siv flange yog xaiv raws li cov khoom siv nrog cov yeeb nkab cov ntaub ntawv. Qhov kev xaiv xaiv no tau ua los tiv thaiv cov kev pheej hmoo galvanic tau. Cov khoom siv tsim nyog rau cov flanges yog txiav txim siab raws li ASTM A-182 tus qauv.

Inconel 718 Alloy tau xaiv tshwj xeeb los ntawm cov kws tsim qauv rau nws lub zog siab hauv kev mob kub heev ntawm ob qho kawg ntawm lub spectrum. Nws tuaj yeem siv los ntawm cov kub tsawg dua txhua txoj kev mus txog 1300¡Ãf \ / 7004¡Ãc. Nws cov khoom ua pov thawj tsis tshua muaj txiaj ntsig, tensile thiab nkag mus rau qhov muaj zog thoob plaws thoob plaws. Nws tseem ua pov thawj zoo tensile thiab cuam tshuam lub zog.

Thaum nce qhov kub thiab txias lub anealed thiab tov annealed alloy qhia zoo tsis kam rau scaling thiab muaj lub zog siab.

304 Piping spools yog tsim los ntawm 304 stainless hlau, ib qho khoom siv nrov thiab nrov tshaj plaws hauv ntau cov ntawv thov uas xav tau kev tiv thaiv kom xeb thiab oxidation. Cov kev tshaj lij no yog preooss siv cov machinery thiab cov txheej txheem tshwj xeeb, uas paub meej tias lawv muaj tseeb thiab ntseeg tau.
