Dab tsi yog qhov sib txawv ntawm lub tiaj vuam flange thiab pob tw vuam flange?
Jun 24, 2022
1. Flat vuam flanges thiab taub qab vuam flanges muaj qhov sib txawv siv tau. Pav ca vuam flanges yog dav siv nyob rau hauv kev sib txuas ntawm carbon steel kav nrog ib tug siab tsawg tshaj li 2.5MPa. Lub sealing nto ntawm tiaj vuam flanges tuaj yeem suav tias yog lubricated, siab thiab qis, tenon thiab tenon. Muaj peb hom groove hom, ntawm cov uas lub lubricated tiaj vuam flange yog dav siv ntau, thiab feem ntau yog siv thaum nruab nrab tej yam kev mob me me, piv txwv li, low-pressure circulating water pipelines. Butt welding flanges yog tsim rau cov kav dej uas muaj kev kub siab thiab kub siab lossis cov kav dej uas muaj kev kub siab thiab tsis tshua muaj kub, thiab kuj tseem siv rau hauv cov kav dej rau kev thauj mus los qee qhov tseem kim, flammable thiab explosive media. Vim tias qhov kev sib khi ntawm lub pob tw vuam flange yog qhov zoo heev, nws tsis yooj yim rau deformed, thiab nws tuaj yeem tiv taus lub siab loj, thiab qhov kev lees txais siab yog nyob rau hauv 16MPa.
2. Cov txheej txheem vuam ntawm tiaj vuam flanges thiab pob tw vuam flanges txawv. Flat welding flanges tsuas yog yuav tsum tau welded rau ntawm ib sab, thiab tsis tas yuav welded lub puab qhov chaw ntawm kev sib txuas ntawm cov yeeb nkab thiab flange, thaum lub taub qab vuam flange yuav tsum tau ob-sided. Vuam, yog li lub pob tw vuam flange txo cov tsos ntawm kev ntxhov siab concentration.
3. Cov lus hais ntawm tiaj vuam flanges thiab pob tw vuam flanges txawv. Vim tias cov cuab yeej tsim khoom ntawm cov vuam flanges yog qhov yooj yim, cov lus hais kuj pheej yig.
Flat welding flange yog hais txog ib hom flange uas txuas nrog cov khoom siv lossis cov kav dej los ntawm cov welds. Cov qauv ntawm lub tiaj vuam flanges yog qhov yooj yim thiab kev siv tshuab yog qhov yooj yim. Nws tuaj yeem muab faib ua ob hom: phaj hom ca vuam flange thiab caj dab ca vuam flange. Pav ca vuam flanges yog dav siv nyob rau hauv ntau yam tsawg siab pipelines.
Butt welding flange kuj yog ib hom flange. Nws yog ib hom flange nrog lub caj dab rau kev hloov pauv thiab lub taub qab vuam txuas nrog cov yeeb nkab puag ncig. Butt welding flanges tsis yooj yim rau deform, muaj kev sib khi zoo, thiab cov lus hais nruab nrab, thiab tau siv dav hauv ntau cov kav dej kub thiab kub.
