Cov ntaub ntawv tseem ceeb thiab kev thov cov yam ntxwv ntawm lub qhov socket) Weld Flanges

Qhov (socket) weld flanges yog ib hom flange uas txuas rau kav dej siv lub qhov (socke siv Lawv tau dav siv nyob rau hauv high - siab} siab, me- txoj hauj lwm uas hla txoj kab uas hla hla. Txoj kev sib txuas no muaj kev sib cav, kev sib khi zoo heev, thiab muaj zog nkees ua kom tau. Txawm li cas los xij, kev ua yeeb yam ntawm cov flange nyob ntawm cov khoom siv. Hauv qab no yog kev tsom xam ntawm cov ntaub ntawv tseem ceeb thiab cov yam ntxwv nquag siv rau lub nqaj ntsaws weld flanges.

 

1. Carbon Steel

Carbon Steel yog ib qho ntawm cov feem ntau siv cov ntaub ntawv rau weld flanges, feem ntau suav nrog ASTM A105 (kev zam txim) thiab A350 lf2 (tsawg} kub siv). Cov pa roj carbon hlau muaj lub zog siab thiab kev ua tau zoo heev, xws li muaj kev lag luam nruab nrab, xws li cov roj av muaj kev lag luam hauv cov roj av, tshuaj lom neeg, thiab kev lag luam tshuaj zoo.

• Cov txiaj ntsig zoo: Tus nqi qis, muaj lub zog siab, thiab yooj yim vuam thiab ua.

• Qhov tsis zoo: Kev tsis zoo corrosion tsis kam, uas yuav tsum muaj kev tiv thaiv ntxiv (xws li cov txheej txheem lossis ob sab hauv ib puag ncig.

 

2. Stainless hlau

Stainless hlau pauv kev sib tw yog feem ntau ua los ntawm cov ntaub ntawv xws li}} yog haum rau cov tub rog ib puag ncig xws li cov tub rog thiab cov khoom lag luam.

• Cov txiaj ntsig zoo: muaj zog corrosion tsis kam, muaj qhov kub thiab kub tsis kam, thiab huv si hauv cov zaub mov thiab tshuaj lag luam).

• Qhov tsis zoo: tus nqi siab dua thiab nyuaj me ntsis rau cov txheej txheem dua li cov roj carbon.

 

3. Alloy Steel

Alloy Steel flanges (xws li astm A182 F5, F9, F11, thiab F22) ib puag ncig muaj zog, xws li cov nroj tsuag hluav taws xob, roj ua kom zoo nkauj, thiab tshuaj lom neeg. Alloy steels txhim kho lawv lub zog thiab kub ua kom dhau los ntawm kev ntxiv cov ntsiab xws li chromium, molybdenum, thiab npib tsib xee.

• Cov txiaj ntsig zoo: muaj siab - kub thiab siab {{1} kub siab, nrog rau cov creep tsis kam zoo.

• Qhov tsis zoo: kim thiab yuav tsum tau kho cua sov.

 

4. Cov ntaub ntawv tshwj xeeb (piv txwv li cov hlau yas, npib tsib xee - raws li alloys)

For extremely corrosive or high-temperature environments, socket weld flanges may also be made of duplex stainless steel (eg, 2205, 2507) or nickel-based alloys (eg, Inconel 600, Hastelloy C-276). Cov ntaub ntawv no muaj zoo tshaj plaws corrosion thiab kub-ua tsis kam, tab sis yog kim heev thiab feem ntau siv hauv cov ntawv thov tshwj xeeb.

 

Lub ntsiab

Yuav tsum xaiv cov khoom siv rau weld flanges yuav tsum txiav txim siab raws cov kev ua haujlwm tshwj xeeb (piv txwv li, thiab xov xwm corrosivity). Carbon Steel yog tsim nyog rau kev khiav hauj lwm dav dav, cov hlau tsis muaj zog, cov ntaub ntawv sib xyaw ua ke, thiab cov ntaub ntawv tshwj xeeb rau cov muaj ib puag ncig. Xaiv cov ntaub ntawv zoo tsis tsuas yog ua kom muaj kev ntseeg tau flange tab sis kuj txuas lub neej ntawm cov raj txheej txheem.
