Stainless hlau flanges muaj cov zoo hlau cov khoom thiab cov khoom kub heev rau corrosion. Lawv feem ntau siv nyob rau hauv steel hlau qhov chaw xws li steel hlau flanges. Stainless hlau flanges tseem ua stainless acid-resistant hlau flanges nrog ib tus hlau hlau. Nws tsis yog yooj yim kom oxidized nrog huab cua, yog li nws yog feem ntau siv hauv cov kav dej hauv tshuab muaj zog thiab khov kho kav dej. Ntawm no, peb muab cov kev ua tau zoo ntawm cov hlau flanges tsis zoo.
Ua ntej, raws li cov khoom siv hlau, nws reacts nrog huab cua nyob hauv ib qho chaw voj voos, yog li hloov cov khoom qub, tiam sis cov hlau flange tsis muaj peev xwm muab passivated nrog oxidant tsim ib qho tawv thiab tawv chromium-nplua nuj oxide tiv thaiv zaj duab xis ntawm qhov chaw. Cr2O3, stainless hlau flanges zoo tiv thaiv ntxiv oxidation kev tig cev. Lwm cov kav hlau, xws li cov kav xa dej hauv dej thiab cov kav dej tooj liab, muaj peev xwm hla tau me ntsis. Qhov no yog qhov tseem ceeb yog vim li cas qhov kev xeb hauv corrosion ntawm cov kav dej tawg ntawm cov kav dej raug qis yog deb tsawg dua li cov kav hlau tsis txhuam.
Ces tus pas hlau flange tsis muaj corrosion kuj ua haujlwm. Cov hlau tsis fais fab tsis muaj qhov khoob zoo li cov pa roj carbon fiber. Nws tsis tas yuav tiv thaiv thaum siv. Cov hlau flange tsis yog ua los ntawm cov kav hlau flanged hlau flanged. Tsis muaj kev txwv ntawm cov tshuaj lom neeg muaj pes tsawg tus dej vim tsis siv cov xim hlau tsis siv hauv txhua qhov. Cov ntsiab lus oxygen, kub, pH thiab hardness ntawm cov dej muaj corrosion kuj zoo; cov kav dej tsis muaj kab muaj peev xwm tuaj yeem tiv thaiv cov nqi siab, txawm tias tus nqi txaus siab tshaj 40 m / s, tseem muaj qhov tsis muaj corrosion npaum li tsawg, tsis tshaj li 0.003 mm / Xyoo yog tsim tshwj xeeb tshaj yog rau cov khoom siv dej siab. Qhov coefficient ntawm thermal expansion ntawm cov hlau flange hlau flange yog zoo li qhov ntawm lub raj raj tooj, uas yog 1.5 npaug ntawm cov luam yeeb hlau. Piv nrog rau cov hlau flange tsis fais fab, qhov hlau tsis flange flange muaj cov yam ntxwv ntawm qeeb expansion thiab contraction.
Tsis tas li ntawd, stainless hlau flanges feem ntau muaj tshuaj lom neeg cov tshuaj tiv thaiv uas yog ib qho tseem ceeb thiab cov ntaub ntawv tiv thaiv ntawm qhov chaw, uas tsis muaj lwm yam co.
