1. Ntau hom weld:
Slip ntawm Flanges: fillet weld yog siv rau vuam ntawm flange yeeb nkab thiab flange.
Weld caj dab Flanges: lub vuam seam ntawm flange thiab cov yeeb nkab yog ncig vuam.
2. Cov khoom sib txawv:
Slip On Flanges yog machined los ntawm zoo tib yam steel phaj nrog thickness raws li qhov yuav tsum tau.
Weld Neck Flanges feem ntau yog ua los ntawm forged steel.
3. Txawv nominal pressures:
Nominal siab ntawm Slip On Flanges: 0.6 - 4.0MPa
Nominal siab ntawm Weld Neck Flanges: 1-25MPa
4. Cov qauv sib txawv
Slip On Flanges: yog hais txog lub flange uas txuas cov kav hlau, cov yeeb nkab fittings, thiab lwm yam rau hauv flange thiab txuas nrog cov khoom siv los yog cov kav dej los ntawm cov welds.
Weld Neck Flanges: lub flange nrog lub caj dab thiab cov yeeb nkab hloov pauv, uas txuas nrog cov yeeb nkab los ntawm lub taub qab vuam.
5.Scope ntawm daim ntawv thov:
Slip On Flanges : Nws muaj feem xyuam rau kev sib txuas ntawm cov kav hlau steel nrog nominal siab tsis tshaj 2.5MPa. Lub sealing nto ntawm flange tuaj yeem ua rau peb hom: hom du, concave convex type thiab mortise type. Daim ntawv thov ntawm flange du yog qhov loj tshaj plaws Nws yog tsuas yog siv nyob rau hauv cov ntaub ntawv ntawm 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.
Weld Neck Flanges: Nws yog siv rau pob tw vuam ntawm flanges thiab kav dej. Nws cov qauv tsim nyog, nws lub zog thiab nruj yog qhov loj, nws tuaj yeem tiv taus qhov kub thiab txias, rov kho dua thiab kub hloov pauv, thiab nws cov sealing yog txhim khu kev qha. Lub caj dab taub qab vuam flange nrog nominal siab ntawm 1.0 ~ 16.0MPa txais concave convex sealing nto.
Lub tiaj vuam flange tsuas yog txuas nrog cov yeeb nkab thiab tsis tuaj yeem txuas ncaj qha nrog lub taub qab vuam yeeb nkab; Butt-welding flanges feem ntau tuaj yeem txuas ncaj qha rau txhua lub pob tw-welding yeeb nkab fittings (xws li lub luj tshib, tees, cov kav dej sib txawv, thiab lwm yam), thiab tau kawg, cov kav dej.
Lub rigidity ntawm lub caj dab taub qab vuam flange yog ntau dua li ntawm lub caj dab ca vuam flange, thiab lub taub qab vuam lub zog yog siab dua li ntawm lub tiaj vuam flange, yog li nws tsis yooj yim rau xau.
Lub caj dab ca vuam flange thiab caj dab pob tw vuam flange tsis tuaj yeem hloov tau ntawm qhov xav tau. Nyob rau hauv cov nqe lus ntawm kev tsim, lub caj dab ca vuam flange (SO flange) muaj loj sab hauv warpage, me me nyhav thiab tus nqi qis. Tsis tas li ntawd, lub caj dab pob tw-welding flange nrog lub npe nominal txoj kab uas hla ntau dua 250 hli (WN yog lub npe luv ntawm WELDINGCHECK) yuav tsum tau kuaj, yog li tus nqi kuj tsawg.
Vuam tiaj tiaj nrog caj dab yog siv dav hauv cov khoom siv roj av, zoo ib yam li Asmeskas tus qauv S0. Butt-welding flanges yog siv rau kev tshaj tawm kev phom sij heev.
Butt-welding flange yog hais txog cov yeeb nkab txoj kab uas hla thiab phab ntsa tuab ntawm qhov kawg txuas, uas yog tib yam li cov yeeb nkab yuav tsum tau welded, ib yam li ob lub kav dej yog welded.
Lub tiaj welding flange yog lub concave platform, nws lub qhov hauv lub qhov yog me ntsis loj dua li cov kab uas hla ntawm cov yeeb nkab, thiab cov yeeb nkab tau muab tso rau hauv cov vuam sab hauv.
Vuam tiaj tiaj thiab taub qab vuam xa mus rau txoj kev vuam ntawm flange thiab cov yeeb nkab txuas. Thaum welding lub tiaj vuam flange, tsuas yog ib sab vuam yog yuav tsum tau, thiab tsis tas yuav welding cov yeeb nkab thiab flange txuas. Vuam thiab installation ntawm vuam flange yuav tsum tau welded rau ob sab ntawm lub flange. Yog li ntawd, lub tiaj vuam flange feem ntau yog siv rau cov kav dej tsis tshua muaj siab thiab nruab nrab siab, thiab lub taub qab vuam flange yog siv rau nruab nrab thiab siab siab cov yeeb nkab txuas. Lub taub qab vuam flange feem ntau yog tsawg kawg yog PN2. 5 MPa, siv lub taub qab vuam kom txo qis kev ntxhov siab. Feem ntau, pob tw vuam flange tseem hu ua siab caj dab flange nrog caj dab flange. Yog li ntawd, tus nqi tsim khoom, tus nqi zog thiab cov khoom siv pabcuam tus nqi ntawm vuam flange yog siab, vim tias tsuas yog ib qho txheej txheem rau vuam flange.
