Q1: Dab tsi tshiab yeeb nkab tsim tswv yim tuaj yeem txhim kho girth weld kev nyab xeeb?
A:Ib qho kev tsim tshiab tshaj tawm cov kav dej uas muaj qhov tseeb qhov tseeb ntawm qhov kawg (tawm - ntawm - roundness thiab circumference sib txawv zero), txo qis misalignment thiab qhov sib txawv. Tsis tas li ntawd, ua kom cov yeeb nkab kawg thickness ua raws li cov qauv kev txhim kho, txhim kho kev sib koom ua ke muaj peev xwm thiab txo qis zog sib piv cov teeb meem-6.
Q2: Yuav ua li cas technology daws cov teeb meem vuam?
A:Cov cuab yeej siv siab tshaj plaws, zoo li qee lub tshuab vuam niaj hnub, txhim kho kev ntseeg siab nrog cov yam ntxwv zoo li ntev - vuam ruaj khov, kev txhawb nqa rau cov xov hlau tshwj xeeb, lub voj voog ua haujlwm siab, thiab kev ua tau zoo hauv qhov chaw hnyav. Qhov no tuaj yeem txo cov nqi kho thiab cov khoom siv poob qis-5.
Q3: Dab tsi yog daim ntawv thov tshwj xeeb ntawm kev txhim kho vuam tshuab hauv kev lag luam offshore?
A:Hauv kev tsim kho lub tsho sab nrauv, kev siv lub zog tshwj xeeb -lub luag haujlwm CO2 / MAG / MMA welder (Arsen CM500C) tau ua haujlwm ruaj khov ntev -vuam nrug nrog cov nqi tso nyiaj siab. Nws ua haujlwm tshwj xeeb flux-cored xov hlau rau ntsug- nce vuam, txo cov cua sov tawm thiab qhov kev pheej hmoo ntawm kev tsis muaj fusion hauv cov phaj tuab, yog li txhim kho qhov zoo thiab txo qis rework-5.
Q4: Dab tsi yog "tsis muaj zog sib txuam" thiab vim li cas nws thiaj li muaj teeb meem?
A:Kev sib piv ntawm lub zog qis tshwm sim thaum lub zog ntawm cov hlau vuam los yog cov cua sov ua kom sov-Teb chaws cuam tshuam (HAZ) qis dua ntawm cov yeeb nkab hauv qab. Qhov no tsim ib qho "mos cheeb tsam" qhov twg cov yas strain tuaj yeem mloog zoo nyob rau hauv kev thauj khoom, ua rau kev sib koom ua ke tsis muaj zog hauv cov raj xa dej-6.
Q5: Dab tsi yog qhov tseem ceeb ntawm cov yeeb nkab geometric dimension ntawm qhov kawg?
A:Qhov ntev geometric (piv txwv li, txoj kab uas hla, phab ntsa thickness, tawm- ntawm- roundness) ntawm cov yeeb nkab kawg yog qhov tseem ceeb. Qhov tsis raug ntawm no ncaj qha ua rau misalignment thiab ua haujlwm zoo ntawm phab ntsa thickness sib txawv hauv girth weld, uas yog thawj qhov ua rau muaj kev ntxhov siab thiab tsis ua haujlwm-6.
