Cov lus qhia sab nrauv thiab kev ua kom muaj kev puas tsuaj
Q1: tus qauv loj npaum li cas rau A53B Welded yeeb nkab?
A1: A53B welded kav yog muaj nyob rau hauv cov nominal ntau thiab tsawg los ntawm 1/8 "txog 26" OD, npog feem ntau cov ntawv thov. Cov feem ntau siv ntau thiab tsawg ntau thiab tsawg los ntawm 1/2 "txog 12" rau cov kav dej thiab kev tsim kho. Phab Ntsa Thickness ua raws cov sijhawm teem sijhawm (5, 20, 40, 40, 60, thiab lwm yam. Diameters diameters (14 "thiab saum toj no) feem ntau yog siv rau kev sib kis dej loj thiab yog 20 meters (20 tshim) tuaj yeem tsim nyog yuav txawv los ntawm cov chaw tsim khoom thiab cov qauv hauv cheeb tsam.
Q2: Qhov seem twg hauv siab puas tau siv rau A53B Welded yeeb nkab?
A2: ASTM A53 qhia meej nruj ntev ntev: Txoj kab uas hla sab nraud yuav tsum yog li ntawm ± 0. {} ± 1% rau cov kav dej me. Phab ntsa thickness kam rau yog +12.5% / {}} 10% rau feem ntau cov sij hawm. Ovality (tawm - ntawm-roundness) yuav tsum tsis pub tshaj 1% ntawm nominal lub taub. Ncaj nraim yog 0.2% ntev. Cov kev ua kom tau cov no kom haum kom haum thaum lub sij hawm vuam thiab compatibility nrog cov qauv fittings. Ntau txoj hlua khi ntau yuav tau teev rau cov ntawv tseem ceeb, txawm tias qhov no nce cov nqi ntau lawm. Cov kws tsim khoom siv Laser Micrometers thiab cov lus pom kev tshuaj ntsuam xyuas cov tshuab los txheeb xyuas kev ua raws.
Q3: Cov nplai cov yeeb nkab luv luv cuam tshuam qhov ntev thiab kev ua tau zoo?
A3: Cov Ntawv Hluav Taws Xob (piv txwv li, 40, 80) Qhia cov phab ntsa tuab rau lub cheeb, nrog cov lej ntau dua cov ntsiab lus thicker phab ntsa. Teem sijhawm 40 muab kev sib npaug ntawm lub zog thiab qhov hnyav rau kev pabcuam dav dav. Teem sijhawm 80 muaj cov kev ntsuas siab dua tab sis nrog cov khoom siv ntau dua thiab qhov hnyav. Qhov tseeb phab ntsa tuab txawv los ntawm nominal loj-}}} }4 muaj 0.154 "phab ntsa thaum 6 lub sijhawm 40 muaj 0.280" phab ntsa. Thicker lub sijhawm txhim kho cov tawg tawg kuj tab sis txo peev xwm vuam nyuaj. Cov kev xaiv cov kev xaiv tsa lub sijhawm kom tsim nyog cov kev xav tau, kev them nyiaj hauv kev kho tub, thiab cov txheej txheem kev xav tau.
Q4: Dab tsi yog qhov sib txawv ntawm nominal thiab qhov ntsuas qhov loj me me?
A4: nominal cov yeeb nkab loj (nps) yog tus lej tsis muaj zog uas muaj qhov tseeb ntawm 2.375 ") Compatibility. Metric sib luag ua raws cov lus sib xws, ua rau muaj qee zaus tsis meej pem cov txheej txheem sib luag.
Q5: Yuav ua li cas cov yeeb nkab xaus npaj rau hom kev sib txuas sib txawv?
A5: A53b kav yog muab rau ntau qhov kev npaj ntau yam: Tool tau xaus (30}}}}}}}}}}}}}}}}}}}}}}} Beveled xaus feem ntau muaj 1/16 "txog 1/8" ntsej muag ntsej muag rau kev siv Weld kom tsim nyog. Cov kav dej feem ntau suav nrog txuas txuas ntxiv (ntev ntev rau xov) thiab tej zaum yuav muab rau nrog cov kaus mom tiv thaiv yas. Kev khomob tshwj xeeb zoo li flared lossis flanged xaus muaj nyob ua cov kev xaiv kev cai. Kev npaj kom zoo yog tseem ceeb rau kev sib koom ua ke kom muaj kev ncaj ncees.
