Puas Lub Ntig Flanges Ntais Muaj Cov Ntxim Muaj Ntxim Muaj Rau Hauv Lub Foob?

Puas muaj Flanges nto puas muaj kev ntxhib los ntawm kev foob?

Puas yog Flanges saum npoo qhov zoo dua? Qhov tseeb, qhov no tsis yog qhov teeb meem, qhov no yuav tsum tau pom qhov twg koj siv, yog li Flanges yuav muaj qhov sib txawv ntawm qhov chaw npau taws, cov nram qab no Flanges cov tuam txhab muab cov lus piav qhia ntawm cov neeg ua haujlwm.

Flanges deg ntxig rau cov nyhuv ntawm qhov sib txuam zoo, tshwj xeeb tshaj yog thaum siv cov thawv uas tsis yog muag muag, qhov nqes dej ntawm qhov sib txig yog qhov tseem ceeb tshaj plaws ntawm kev ntub. Piv txwv, xa cov Flanges nto ntawm rab riam yog siv kauv hlau, siv cov cav hlau, yog qhov roughness tus nqi loj, lub gasket tsis tuaj yeem thaiv pob riam hniav ua los ntawm lub kauv phom, nyob rau hauv siab, cov xov xwm yuav nws leaked cia no trench.

Lub tshuab gasket muaj ib qib qis ntawm kev sib txig ntawm Flanges nto, vim nws yooj yim rau deform thiab thaiv thaiv qhov ntug, yog li tiv thaiv tsis tau. Ntawm lub thawv rau ntawm lub qhov muag, Cov Flanges yog ib qho yooj yim heev tab sis tsis yog phem, vim hais tias lub sij hawm no tus neeg txuas mus ua haujlwm me me.

Yog li, thaum peb yuav cov Flanges tuaj yeem siv raws li lawv qhov chaw kom paub meej tias nws yog qhov tsim nyog rau tus taw los yog qhov nyuaj, qhov tseeb, koj tsis paub nyob qhov twg rau sab laj Flanges cov neeg ua haujlwm, peb yuav muab koj muab qhov zoo tshaj plaws siv qhov kev pab cuam.

Stainless hlau Flanges, vim tias steel tsis muaj corrosion kuj zoo, vim li ntawd nws tuaj yeem ua rau cov yam ntxwv ua kom muaj kev ruaj ntseg ntawm cov qauv tsim. Flanges tsis ua kom muaj corrosion, pitting, corrosion or wear. Chromium-muaj Flanges kuj muab kev dag zog thiab siab elongation nyob rau hauv ib qho yooj yim, kev tsim khoom yooj yim, txaus siab rau cov kev xav tau ntawm architects thiab cov qauv tsim. Txhua hom hlau ua pa nrog cov pa oxygen hauv cov cua kom tsim muaj oxide zaj duab xis nyob ntawm qhov chaw. Yog hais tias qhov tsim, qhov saum npoo ntawm cov hlau tau ruaj khov los ntawm kev pleev xim rau xim los yog ib qho oxidation resistant hlau, tab sis, raws li paub, qhov kev tiv thaiv no tsuas yog ib zaj duab xis.

Flanges nyob rau hauv kev siv cov txheej txheem muaj xws li:

1, chrome Flanges yeeb nkab tom qab lub zog ntawm American qauv flanges Flanges loj dua, nws txawj tawg. Yog tias tib hom chromium stainless hlau electrode (G202, G207) welding, yuav tsum muaj ntau tshaj 300 ℃ thiab 700 ℃ tom qab qhov kev kho mob qeeb. Yog tias lub weldment tsis tuaj yeem yog cov kev kho cua sov tom qab, koj yuav tsum siv Flanges yeeb nkab electrode (A107, A207).

2, Flanges, txhawm rau txhim kho qhov corrosion thiab weldability thiab tsim nyog nce nyob rau hauv tus nqi ntawm stability ntsiab Ti, Nb, Mo, etc., zoo tshaj lub chromium Flanges zoo dua. Thaum siv hom Chromium Flanges electrode (G302, G307), yuav tsum ntau tshaj 200 ℃ preheating thiab 800 ℃ tom qab qhov kub ntxhov nyob ib ncig ntawm txoj kev kho mob. Yog tias cov weldment tsis tuaj yeem kho cua sov, koj yuav tsum siv Flanges fittings electrode (A107, A207).

3, thiaj li tiv thaiv tau Flanges cov cua kub los ntawm qhov muag corrosion, vuam tam sim no yuav tsum tsis txhob ntau, tsawg tshaj li 20% ntawm cov hlau electrode, lub arc yuav tsum tsis dhau ntev, txias ntawm cov khaubncaws sab nraud povtseg, .

4, lub electrode yuav tsum tau siv kom qhuav, titanium calcium yam yuav tsum tau qhuav ntawm 150 ℃ rau 1 teev, tsis tshua muaj hom hydrogen yuav tsum yog 200-250 ℃ drying 1 teev (tsis tuaj yeem rov ziab ntxiv, lossis yoojyim rau tev tawv nqaij ntawm tawv nqaij ), los tiv thaiv Welding paste roj thiab lwm cov av, thiaj li tsis ua rau cov hlua khi kom ua rau cov ntsiab lus ntawm cov roj thiab cuam tshuam rau qhov zoo ntawm cov vuam.

5, Flanges yeeb nkab vuam, los ntawm dua cua kub los ntawm carbides, txo corrosion kuj thiab mechanical zog.

6, low-pressure yeeb nkab tuaj yeem siv cov hlau Flanges, ntau tshaj 4 kg siab siv vuam Flanges, lub electrode yuav tsum muaj kev txhim kho corrosion thiab oxidation kuj. Ntxiv ib qho gasket ntawm ob qhov Flanges thiab zawm nws nrog bolts. Ntau lub siab Flanges muaj txawv thickness thiab siv ntau yam bolts.
