Qhov sib txawv ntawm caj dab taub qab vuam flange thiab caj dab ca vuam flange

1. Cov ntaub ntawv weld yog txawv: fillet weld yog daim ntawv ntawm vuam vuam ntawm cov yeeb nkab thiab flange nrog caj dab ca vuam flange, thaum lub voj voog ncig yog daim ntawv vuam vuam ntawm caj dab taub qab vuam flange thiab yeeb nkab;
2. Cov ntaub ntawv sib txawv: cov khoom siv ntawm lub caj dab ca vuam flange yog machined los ntawm cov hlau zoo tib yam nrog cov thickness yuav tsum tau, thaum cov khoom ntawm lub caj dab taub qab vuam flange feem ntau yog machined los ntawm forged steel qhov chaw;
3. Lub nominal siab txawv: lub nominal siab ntawm lub caj dab ca vuam flange yog 0 6 -- 4 0MPa, thaum lub nominal siab ntawm lub caj dab taub qab vuam flange yog {{ 4}}MPa.
4. Lwm qhov tseem ceeb yog qhov sib txuas ntawm lub caj dab pob tw-welding flange thiab cov yeeb nkab txuas yog nyob rau hauv chav kawm B seam, thiab qhov sib txuas ntawm lub caj dab plam-welding flange thiab cov yeeb nkab txuas yog rau Class C seam. Tom qab-weld NDT yog txawv.
5. Lub caj dab tiaj tus vuam flange thiab lub caj dab pob tw vuam flange tsis tuaj yeem hloov pauv tsis tu ncua. Los ntawm kev tsim khoom ntawm kev pom, txoj kab uas hla loj ntawm lub caj dab tiaj tiaj vuam flange (SO yog lub npe luv ntawm SLIP ON) txhais tau hais tias qhov hnyav me me thiab tus nqi qis. Tsis tas li ntawd, lub caj dab taub qab vuam flange (WN yog lub ntsiab lus ntawm WELD NECK) nrog lub npe nominal txoj kab uas hla ntau dua 250mm yuav tsum tau kuaj. Lub flange ntawm SO tsis tas yuav tsum tau kuaj, yog li tus nqi qis.
