Cov kev qhia txog kev tiv thaiv rau cov hlau stainless flange thaum lub sijhawm kev teeb tsa Ua kom tsis txhob cuam tshuam qhov xeb kev txhim kho los ntawm kev ua kom sov los ntawm cov hlau tsis sib thooj npog, lub vuam tam sim no yuav tsum tsis txhob loj dhau. Lub sijhawm no, qhov tam sim no yuav tsum tau kwv yees li 20% me dua cov pa roj carbon steel electrode, arc yuav tsum tsis txhob ntev dhau, cov interlayer yuav tsum tau txias sai, thiab lub weld yuav tsum raug txo kom tsawg.
Thaum vuam hlau stainless flange yeeb fittings, rov ua kom sov yuav ua kom cov carbides, thiaj li txo qhov tsis muaj corrosiveness thiab cov tshuab ua haujlwm. Stainless hlau flange yeeb fittings yooj yim tawg tom qab vuam. Yog hais tias tib hom kev xaim hlau stainless siv rau vuam, preheating siab tshaj 300 degrees Celsius thiab txias txias txog li 700 degrees Celsius tom qab vuam tuaj yeem tiv thaiv cov yeeb nkab flange los ntawm kev tawg.
Yog tias cov hlau txuas tsis tuaj yeem kho kub tom qab vuam, yuav tsum tau xaiv cov kab hlau tsis xeb hlau flange electrode. Txhawm rau txhawm rau txhim kho kev txhim kho corrosion thiab weldability, nyob rau hauv cov ntaub ntawv ntawm stainless hlau flanges, tsim nyog nce qhov ruaj ntseg cov ntsiab lus ntawm titanium, niobium, molybdenum, thiab lwm yam Yuav tsum tau nce. Thaum siv tib hom stainless hlau flange electrode, nws yuav tsum tau preheated siab tshaj 200 degrees Celsius thiab txias txog ntawm 800 degrees Celsius tom qab vuam.
Yog tias qhov txuas tsis tuaj yeem kho kub, qhov tsim nyog ntawm stainless hlau flange cov yeeb nkab uas haum electrode yuav tsum tau xaiv. Lub taub hau stainless hlau muaj cov hlau ua haujlwm zoo thiab muaj zog tiv thaiv kev kub ntxhov. Nws yog feem ntau siv rau hauv kev teeb tsa steel. Cov tawv hlau saum npoo ntawm cov hlau tsis huv flange yog lubricated thiab tsis yog yooj yim oxidized los ntawm huab cua. Yog li, nws tau feem ntau siv cov kav dej loj hauv tsev siab thiab corrosive siab kav, thiab tsis muaj cov haujlwm zoo ntawm xeb hlau flanges.
