Kuv yuav tsum xyuam xim rau dab tsi thaum siv lub caj dab taub qab vuam flange?

Tag nrho cov hlau nrogcaj dab taub qab vuam flangefittings yuav hnov ​​​​mob nrog atmospheric oxygen, tsim cov oxide zaj duab xis rau ntawm qhov chaw. Cov khoom yuav tsum tau ntsia raws li cov lus qhia, thiaj li ua kom lub cev ua haujlwm ntawm cov khoom yav tom ntej. Niaj hnub no, muaj ntau yam khoom qauv. Nrog rau kev nruam ntej ntawm kev tshawb fawb thiab thev naus laus zis, cov khoom kho tshiab muaj ntau thiab ntau dua raws li cov neeg xav tau. Tshwj xeeb, lub tuam txhab cov khoom lag luam niaj hnub txhim kho kev ua tau zoo.

Yog tiascaj dab taub qab vuam flangeyog welded nrog tib hom chromium stainless hlau electrode (G202, G207), nws yuav tsum tau preheated rau ntau tshaj 300 tom qab vuam, thiab maj mam txias ntawm txog 700. Yog hais tias lub weldment tsis tau tshav kub-kho tom qab vuam, lub electrode nrog caj dab. weld flange fittings yuav tsum tau siv.

Kuv yuav tsum xyuam xim rau dab tsi thaum siv lub caj dab taub qab vuam flange?

1. Flangefittings nrog caj dab taub qab vuam tau zoo corrosion kuj thiab oxidation kuj nyob rau hauv vuam pas nrig thiab taub qab vuam flange, dav siv nyob rau hauv tshuaj chiv, tshuaj kev lag luam, roj av thiab kev kho mob machinery manufacturing.

2. Thaum welding ntawm flangefittings nrog caj dab taub qab vuam, carbides yog precipitated los ntawm rov ua cua sov, uas ua rau cov neeg kho tshuab tsis muaj zog thiab corrosion kuj.

3. Hardening American standard flange nrog caj dab taub qab vuam flange fittings yog loj dua tom qab vuam thiab yooj yim rau tawg. Yog tias tib hom chromium stainless hlau electrode (G202, G207) vuam, yuav tsum muaj ntau tshaj 300 preheating thiab 700 qeeb txias kho tom qab vuam. Yog tias qhov vuam tsis tuaj yeem kho cua sov tom qab vuam, cov electrode nrog caj dab vuam flange fittings (A107, A207) yuav tsum tau xaiv.

Kev yug ntawm cov khoom rau tib neeg lub neej tau coj ntau yam kev yooj yim, cov khoom tsis zoo li qub, tab sis nrog kev txhim kho ntawm science thiab technology innovation. Yog li ntawd, nws yog ib qho tseem ceeb heev los xaiv cov khoom tsim nyog rau koj tus kheej cov txiaj ntsig.

Vim yog qhov zoo corrosion kuj ntawm stainless hlau, cov tswv cuab ntawm cov txheej txheem tuaj yeem khaws cia mus tas li nrog kev ncaj ncees ntawm kev tsim engineering. Chrome stainless hlau stamping flanges tseem muab cov cuab yeej siv zog nrog kev ua haujlwm siab thiab yooj yim los tsim kom tau raws li cov kev xav tau ntawm cov kws tsim qauv thiab cov qauv tsim.
