Flange muaj kev ua tau zoo, yog li nws feem ntau siv rau hauv kev tsim kho tshuaj, kev tsim kho, dej thiab kev tso dej, roj av, lub teeb thiab hnyav kev lag luam, tub yees, huv si, kav dej, hluav taws xob tiv thaiv, hluav taws xob, aerospace, shipbuilding thiab lwm yam engineering,
Flanges yog cov yeeb nkab fittings cais raws li hom kev sib txuas nrog cov kav dej. Feem ntau, nws tuaj yeem muab faib uatiaj welding flange nrog caj dab, taub qab vuam flange nrog caj dab, qhov (socket) vuam flange, lwm.
Lub sealing nto ntawm flange muaj ntau hom, xws li protruding, concave thiab tag nrho cov dav hlau.
Dab tsi yog daim ntawv thov ntawm caj dab flange hauv lub neej niaj hnub?
Ua ntej tshaj plaws, nkag siab qhov zoo ntawm lub caj dab taub qab vuam flange. Lub caj dab taub qab vuam flange txhim kho lub zog ntawm flange thiab lub zog ntawm lub flange. Nws yog feem ntau siv nyob rau hauv high-pressure pipelines.
Qhov kom zoo dua ntawm lub caj dab taub qab vuam flange yog los txuas cov kav dej thiab tswj kev sib khi ntawm cov kav dej. Nws yog qhov yooj yim los hloov ib ntu ntawm cov kav dej. Qhov no ua kom yooj yim tshem tawm thiab tshuaj xyuas qhov xwm txheej ntawm cov kav dej thiab kaw ib ntu ntawm cov kav dej. Lub caj dab flange feem ntau yog siv los hloov cov khoom siv thaum sib txuas. Lub nplhaib hlau muab tso rau ntawm cov yeeb nkab kawg thiab lub flange tuaj yeem txav mus rau ntawm cov yeeb nkab kawg. Lub nplhaib steel lossis flange yog qhov sib khi, thiab cov haujlwm ntawm flange yog compressed.
Lub caj dab slip-on flange yog ib qho flange txav tau, uas feem ntau yog txuam nrog cov khoom siv dej thiab cov kav dej (feem ntau ntawm cov pob qij txha expansion). Muaj ib lub flange ntawm ob qho kawg ntawm kev nthuav dav sib koom ua ke, uas tuaj yeem txuas ncaj qha rau cov kav dej thiab cov khoom siv hauv qhov project.
Butt-welding flanges muaj nyob rau hauv ntau hom thiab qauv. Butt-welding steel flanges yog siv rau pob tw vuam ntawm flanges thiab kav dej. Feem ntau yog siv rau vuam txheej txheem. Nws muaj cov yam ntxwv zoo siv thiab kev ua tau zoo, tsim nyog qauv, siab zog thiab rigidity. Nws yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb rau vuam tus nqi thiab kev ua haujlwm ntawm flange thiab tuaj yeem tiv taus qhov kub thiab txias. Siv, txiav txim siab txog kev siv raws li tus yam ntxwv. Nws yog tsuas yog siv nyob rau hauv nruab nrab nruab nrab tej yam kev mob, xws li tsis tshua muaj siab tsis-purified compressed cua thiab tsis tshua muaj siab circulating dej. Nws qhov zoo dua yog tias tus nqi qis dua. Nws muaj feem xyuam rau kev sib txuas ntawm cov kav hlau steel nrog nominal siab tsis tshaj 2.5MPa. Lub sealing nto ntawm vuam flange yuav muab faib ua hom du, concave-convex hom thiab tenon hom. Lub tiaj vuam flange yog dav siv.
Butt-welding flange tuaj yeem tiv taus qhov kub thiab txias, rov kho dua thiab kub hloov pauv, thiab kev sib khi ua haujlwm. Butt-welding flanges nrog lub nominal siab ntawm 0.25 ~ 2.5MPa feem ntau siv concave thiab convex sealing nto.
