Cov kev paub ua teb thiab kev daws teeb meem
Q1: Yuav ua li cas koj ho paub qhov txawv A106b yeeb nkab los ntawm lwm cov ntaub ntawv zoo sib xws li A53 lossis stainless hlau hauv daim teb?
A1:Hauv teb, ntau txoj kev ceev tuaj yeem siv. Ua ntej, khij cov stenciled lossis cim cim ntawm cov yeeb nkab nws tus kheej; Nws yuav tsum kom meej meej lub xeev "A106b". Yog tias cim tau faded, ib qho kev sim ua kom zoo tuaj yeem ua tau zoo: Siv ib lub ntsej muag, Carbon Steel) ua rau lub ntsej muag daj {}}}} txiv kab ntxwv ntsuab nrog ntau rab rawg ntev. Nyob rau hauv kev sib piv, tus hlau stainless (piv txwv li, 304) tsim tawm tsawg heev, luv luv, liab taws. A53 tuaj yeem saib zoo ib yam li qub, yog cim yog qhov tseem ceeb. Cov hlau nplaum yuav muaj zog ua rau A106b. Rau qhov meej dua tab sis tseem yoojyim {{14} Tus phooj ywg tus phooj ywg, kev ntsuas tshuaj lom neeg nrog lub acid poob tuaj yeem siv rau ntawm qhov chaw foob; Carbon Steel yuav tsis muaj qhov tsis meej, thaum stainless hlau yuav qhia ib qho kev sib txawv. Yuav tsum siv PPE tsim nyog rau cov kev ntsuam xyuas no.
Q2: Qhov kev nqis tes ua tam sim yog kev ua si uas muaj cov yeeb nkab A106B tau pom hauv lub siab?
A2:Kev nyab xeeb yog qhov tseem ceeb tshaj plaws. Qhov kev ua tam sim yog:1. Cais tawm:Nrhiav tam sim ntawd thiab kaw qhov ze tshaj plaws thiab cov kav dej hauv dej ntws mus rau cov ntu thiab cais cov xau.2. Kev ruaj ntseg thaj chaw:Pov thawj thaj chaw kom tiv thaiv cov neeg ua haujlwm los ntawm kev nkag mus rau {}}}}}} qhov siab ua kom muaj kev raug mob lossis kev puas tsuaj loj.3. Qhov cua thiab ntws:Thaum raug rho tawm, maj mam ua rau lub siab siab thiab ua rau cov kua uas seem ntawm seem los ntawm cov khoom siv hluav taws xob lossis vents.4. Daim ntawv tshaj tawm:Ceeb toom cov haujlwm, txij nkawm, thiab cov neeg ua haujlwm nyab xeeb tam sim ntawd.5. Tshawb xyuas:Tsuas yog tom qab cov yeeb nkab yog kev tawm tsam tag nrho thiab drained yuav tsum cov neeg ua haujlwm kom ze rau kev txheeb xyuas qhov ua rau kev kho kom zoo thiab npaj kho.
Q3: Lub sijhawm haum -}} li, dab tsi yog qhov lees paub txog kev sib tw ("hi- lawb weld?
A3:Ib txoj kev ua kom haum yog qhov tseem ceeb rau Weld Kev Ncaj Ncees. Raws li cov qauv zoo li ASME B31.3, lub hauv paus sab hauv (hi {} LOCH (1 hli) Rau cov phab ntsa thicker, kev ua siab ntev yog feem ntau tau teev tseg yog 0.25t lossis 3 hli (0.125 hauv), qhov twg yog qhov tsawg dua. Misalignment tshaj cov kev txwv no tsim kev ntxhov siab kis uas tuaj yeem ua rau tawg. Nws yuav tsum raug kho los ntawm re-}}}}}} Txoj kev ua tsis ncaj rau cov kav dej uas tsis dhau ib qho dua 1: 3 nqes los pab txhawb txoj kev hloov pauv smoother.
Q4: Qhov kev pom zoo tau pom zoo rau ib ntus qhib qhib ntawm A106B yeeb nkab thaum muaj kev tsim kho kom tsis txhob muaj kev sib kis?
A4:Tiv thaiv kev sib kis sab hauv (los ntawm av, dej, tsiaj) yog qhov tseem ceeb heev. Cov txheej txheem pom zoo yog siv ruaj ruaj, nruj - fitting yas lossis hlau lub kaus mom tshwj xeeb tsim rau cov yeeb nkab tiv thaiv. Rau cov kab uas sib txawv loj, hnyav- Duty works} Duty wrants nrog kev rub tawm cov hlua sib tw muaj ntau. Rau cov diam diam me me, rigid yas laub - haum}- shrink lub kaus mom yog ua tau zoo. Raws li ib daim teb kev daws teeb meem ib ntus rau cov khoom qhib loj, ib qho hnyav {8} Nyob ib ncig ntawm cov kab yas ruaj khov lossis cov kab xev uas muaj zog siv tau, tab sis qhov no tsis muaj zog tsawg. Tsis muaj ib qho xwm txheej twg yuav tsum muab khaub ncaws, ntawv, lossis duab los qhia yooj yim, ua kom muaj kev cuam tshuam nrog noo noo, lossis ua kom pom cov hmoov av rau hauv lub system.
Q5: Tus tswv cuab yog muaj teeb meem ua tiav lub hauv paus zoo ntawm A106B yeeb nkab. Dab tsi yog cov teb feem ntau -} cuam tshuam rau?
A5:Cov teb sib xws - muaj cov laj thawj rau cov tsis zoo hauv paus ntawm cov:1. Tus tsis haum haum li - up:Ntau qhov sib txawv los yog misalignment sab nraud kam rau yus.2. Hmoov:Ib puag ncig ntawm ya raws hauv huab cua, ntawm cov yeeb nkab saum npoo, lossis hauv vuam electrodes (yog tias tsis khaws cia hauv qhov cub). Qhov no qhia txog cov dej ntau, ua rau porosity.3. Cua:DRAFTS kev cuam tshuam cov ntaub thaiv cov roj rau ntawm Tig lossis Mig Welds, Ua rau Porosity.4. Tsis yog Curge:Rau TIG hauv paus dhau mus, tsis txaus ntseeg Argon rov qab los yog ntxuav tus nqi Flow, ua rau qab zib (oxidation) ntawm cov hlaws dai sab hauv.5. Cov Txheej Txheem Tsis Muaj:Tsis zoo amperage, taug kev nrawm, lossis electrode lub.6. Tsis muaj preheat:Tshwj xeeb tshaj yog nyob rau phab ntsa thicker lossis hauv huab cua txias, ua rau txias txias thiab muaj peev xwm tawg. Txoj kev daws teeb meem cuam tshuam nrog kev kuaj xyuas thiab kho txhua qhov ntawm cov xwm txheej no.
