Raws li tus qauv SANS 1123, muaj ntau ntau hom plam ntawm flanges, vuam caj dab flanges,lap joint flanges,qhov muag tsis pom flangesthiabthreaded flanges.
Hais txog cov qauv loj, SANS 1123 txawv ntawm cov qauv Asmeskas, Nyiv thiab European. Hloov chaw, PN thiab K, SANS 1123 tau txais kev sawv cev tshwj xeeb: Piv txwv li, nrog caj dab tiaj vuam flange 600/3, 1000/3, 1600/3, 250/3, 4000/3, nrog caj dab taub qab vuam flange yog sib txawv, 600/2, 1000/2, 1600/2, 250/2, 4000/2, dig muag flange yog 600/8, 1000/8, 1600/8, 2500/8, 4000/8, threaded flange yog 600/ 4, 1000/4, 1600/4, 2500/4, 4000/4, xoob flange yuav customized loj.
SANS 1123 flange yog nyob ze rau European flange cim nrog PN, thiab nws qhov ntsuas qhov siab ntawm 250 kPa mus rau 4000 kPa, uas tau hloov mus rau qhov ntsuas siab cim nrog PN, uas yog PN 2.5 rau PN 40, tab sis nws qhov ntsuas kub yog - 10 ℃ to 200 ℃, thiab qhov ntsuas kub siv tau yog me me. Tom qab kev txheeb xyuas, nws tau pom tias, piv nrog BS EN 1092-1 flange, nyob rau hauv tib lub npe loj thiab cov chav kawm siab, txawm hais tias qee qhov loj dua nominal flanges ntawm SANS 1123 flange yog thinner, flange sab nraud txoj kab uas hla, ntsia liaj qhov rooj qhov chaw. lub voj voog txoj kab uas hla, fastener sets thiab xov specification, uas txiav txim seb lub ob flanges yuav kho los ntawm fasteners, yeej ib txwm zoo tib yam flange kev twb kev txuas loj, Yog li ntawd, SANS 1123 flange yeej ua tau raws li qhov yuav tsum tau ntawm ntau yam yeeb nkab khoom qib nyob rau hauv qhov project no.
Vim tias cov txheej txheem tsim khoom ntawm South African steel kav feem ntau yog qab ntawm cov teb chaws tsim nyob rau hauv Tebchaws Europe thiab Tebchaws Meskas, cov kev qhia ntawm cov yeeb nkab steel uas ua raws li South African qauv yog tsawg thiab lub siab muaj peev xwm raug txwv, South African steel. yeeb nkab txheem ntawm qhov project no tsuas yog siv rau cov pa roj carbon steel kav uas tsis tshua muaj kub thiab tsis tshua muaj siab, thiab cov pa roj carbon steel kav nrog tsim siab ＞ 2.5 MPa los yog tsim kub ＞ 100 ℃ thiab tag nrho cov kav hlau stainless txais yuav American qauv. Cov tshuaj muaj pes tsawg leeg thiab lub zog Performance index ntawm steel yeeb nkab cov ntaub ntawv nyob rau hauv South African steel yeeb nkab qauv thiab American steel yeeb nkab qauv muaj qee qhov sib txawv, thiab qee cov kav hlau muaj qhov sib txawv sab nraud (saib Table 1, xws li DN65). Txawm hais tias qhov teeb meem ntawm qhov sib txawv ntawm cov khoom muaj pes tsawg leeg ntawm cov yeeb nkab steel puag cov khoom ntawm ob qhov kawg ntawm qhov vuam tuaj yeem daws tau los ntawm kev xaiv cov vuam rods thiab kev txhim kho cov txheej txheem vuam, thiab qhov teeb meem ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov kab. steel yeeb nkab ntawm ob qho kawg ntawm lub pob tw weld tuaj yeem daws tau los ntawm kev sib tw staggered, qhov no yuav ua rau muaj teeb meem loj rau kev tsim kho cov kav dej thiab tsis ua rau muaj kev lav phib xaub ntawm kev tsim kho zoo. Lub sealing kev twb kev txuas tuaj yeem pom tau los ntawm kev koom tes ntawm flange, gasket thiab fastener. Lub gasket cais cov flanges ntawm ob qho kawg, thiab lub fastener tsis xav tau tib yam khoom ntawm flanges ntawm ob qho kawg. Yog li ntawd, qhov sib txawv ntawm cov khoom muaj pes tsawg leeg thiab sab nraud txoj kab uas hla ntawm cov kav hlau steel ntawm ob qho kawg tuaj yeem daws tau. Tom qab tag nrho, kev sib txuas ntawm cov kav hlau steel nrog cov qauv sib txawv feem ntau tshwm sim ntawm qhov chaw uas cov khoom siv yeeb nkab hloov qib. Xws li cov pob qij txha tsis muaj ntau, thiab kev siv flanges yuav tsis ntxiv cov nqi ntau rau qhov project.
