Qhov sib txawv ntawm cov qauv ntawmcaj dab tiaj vuam flangesthiabcaj dab taub qab vuam flangeslies nyob rau hauv cov sib txawv kev twb kev txuas hom ntawm nooks thiabflanges. Lub caj dab tiaj welding flangesfeem ntau nooks thiabflangesAngle kev twb kev txuas, thaumcaj dab taub qab vuam flangesyog flanges thiab nooks taub qab txuas.
1, centrifugal twj tso kua misflangetxoj kev sib txuas yog txawv:caj dab tiaj vuam flangethiab caj dabtaub qab vuam flangenyob rau hauv cov qauv ntawm qhov sib txawv yog qhov sib txawv kev sib txuas ntawm cov yeeb nkab thiabflange, caj dab tiaj vuam flangefeem ntau yog cov yeeb nkab thiab flange Angle kev sib txuas, thiabcaj dab taub qab vuam flangeyog flange thiab yeeb nkab taub qab.
Flat vuam flangesfeem ntau tsuas yog txuas nrog cov yeeb nkab, tab sis tsis tuaj yeem txuas ncaj qha nrog lub pob tw-welding yeeb nkab haum;Butt-welded flangestuaj yeem txuas ncaj qha rau txhua lub pob tw-welded yeeb nkab fittings (xws li lub luj tshib, tees, reducers, thiab lwm yam), nrog rau cov kav dej, tau kawg.
2, centrifugal twj tso kua mis flange weld cov ntaub ntawv yog txawv: tiaj welding weld tsis tuaj yeem kuaj radiographic, thiab vuam vuam tuaj yeem ua tau. Hom vuam seam ntawm cov yeeb nkab thiab flange nrog caj dab ca vuam flange yog fillet weld, thaum hom vuam seam ntawm flange thiab yeeb nkab nrog caj dab yog girth weld. Flat welding yog ob fillet girth welds thiab taub qab vuam yog ib lub pob tw girth welds. Qhov sib txawv ntawm flanges nrog caj dab thiab flanges tsis muaj caj dab yog tias flanges nrog caj dab muaj ib qho chaw ntxiv rau hauv cov kav dej vuam qhov chaw dua li flanges tsis muaj caj dab. Flanges tsis muaj caj dab kuj yog flanges tiaj tus. Tus thawj tsis muaj flange kuj yog tiaj tus fillet weld. Lub vuam seam ntawm lub pob tw-welding flange nrog lub caj dab thiab cov yeeb nkab kev sib txuas yog nyob rau hauv chav kawm B seam, thiab vuam seam ntawm lub tiaj vuam flange nrog lub caj dab thiab cov yeeb nkab txuas yog nyob rau hauv chav kawm C seam, thiab qhov kev ntsuam xyuas tsis yog qhov sib txawv. tom qab vuam.

3, nominal siab txawv: lub nominal siab ntawm caj dab ca vuam flange: 0.6-- 4.0Mpa, thiab lub nominal siab ntawm caj dab taub qab vuam flange: 1- 25Mpa qib, pom tseeb, qib siab ntawm caj dab ca vuam flange yog qis dua.
4. Lub pob tw welding flange nrog caj dab yog loj dua li ntawm lub tiaj vuam flange nrog caj dab. Lub zog ntawm lub pob tw vuam yog siab dua li ntawm cov vuam vuam, thiab nws tsis yooj yim rau xau.
Flat welded flanges nrog caj dab thiab pob tw-welded flanges nrog caj dab tsis tuaj yeem hloov tau ntawm qhov xav tau. Los ntawm qhov kev xav ntawm kev tsim khoom, tiaj tus welded flanges nrog caj dab (SO yog lub ntsiab lus ntawm SLIPON) nrog loj sab hauv warp txhais tau tias qhov hnyav me me thiab tus nqi qis. Tsis tas li ntawd, lub caj dab pob tw-welded flanges nrog nominal txoj kab uas hla ntau dua 250mm (WN yog lub ntsiab lus ntawm Weldingneck) yuav tsum tau sim, thaum flanges nrog SO tsis tas yuav tsum tau kuaj. Yog li tus nqi kuj tsawg.
