Cov txheej txheem vuam sib txawv: Cov txheej txheem vuam rau caj dab flange kav yog fillet vuam, thaum vuam txoj kev rau caj dab taub qab vuam flanges thiab cov kav dej yog ncig vuam. Cov ntaub ntawv sib txawv: cov khoom siv flange rau caj dab ca vuam yog ua tiav nrog cov tuab tuab zoo tib yam steel daim hlau raws li qhov yuav tsum tau ua, thaum cov khoom flange rau caj dab taub qab vuam yog tsim los ntawm forged steel qhov chaw, nrog rau qhov sib txawv nominal pressures: lub nominal siab rau caj dab ca vuam flanges yog {{0}}.6 ~ 4.0MPa, thiab lub nominal siab rau caj dab vuam flanges yog 1 ~ 25 MPa.
Lub weld seam nruab nrab ntawm lub caj dab taub qab vuam flange thiab cov yeeb nkab belongs rau Class B weld seam, thaum lub weld seam nruab nrab ntawm lub caj dab ca vuam flange thiab cov yeeb nkab sib koom ua ke belongs rau Class C. Qhov kev ntsuam xyuas tsis muaj kev puas tsuaj tom qab vuam sib txawv. Lub caj dab ca vuam flange thiab lub caj dab pob tw vuam flange tsis tuaj yeem hloov pauv tau. Los ntawm kev tsim khoom, lub caj dab ca vuam flange (SLIPON) yog qhov loj, hnav, thiab siv tau zoo. Tsis tas li ntawd, pob tw welded flanges nrog lub nominal txoj kab uas hla ntau dua 250 mm (WN luv luv rau WELLINGNECK) kuj yuav tsum tau kuaj rau tus nqi qis.
Cov duab ntawm lub vuam seam yog txawv: tiaj weld seams tsis tuaj yeem kuaj xyuas los ntawm hluav taws xob, thaum lub pob tw weld seams raug tshuaj xyuas los ntawm hluav taws xob. Lub vuam txoj kev rau flanges yog fillet welding, thaum lub vuam txoj kev rau caj dab vuam flanges thiab fittings yog circumferential vuam, tiaj vuam yog ob lub ces kaum circumferential vuam, thiab pob tw vuam yog pob tw vuam circumferential welding. Qhov sib txawv ntawm lub tiaj vuam flange nrog lub caj dab thiab lub tiaj vuam flange tsis muaj caj dab yog.
Hauv qhov chaw vuam ntawm cov kav dej, muaj cov vuam flanges ntau dua nrog lub caj dab dua li cov tsis muaj caj dab. Tsis yog caj dab tiaj vuam flanges kuj yog lub kaum sab xis welds, thiab cov thawj coj tsis flange kuj yog lub kaum sab xis. Weld seam nrog caj dab taub qab vuam flange thiab nozzle belongs rau Class B sib koom tes, thaum lub weld seam nrog caj dab ca vuam flange thiab nozzle belongs rau Class C sib koom tes, thiab cov kev ntsuam xyuas tsis muaj kev puas tsuaj tom qab vuam yog txawv.
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 ca vuam flange yog 1 ~ 25 MPa. Obviously, qhov tsim nyog theem ntawm lub caj dab ca vuam flange yog qis dua, thiab txoj kev sib txuas yog txawv: qhov sib txawv loj ntawm lub caj dab ca vuam flange thiab lub caj dab taub qab vuam flange nyob rau hauv txoj kev sib txuas ntawm cov raj xa dej thiab flange. Lub caj dab ca vuam flange feem ntau yog txuas nrog lub flange lub kaum ntse ntse, thaum lub caj dab taub qab vuam flange yog qhov sib txuas ntawm lub flange thiab cov kav dej.
