Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) feem ntau ua rau cov kav hlau ua ntej lawv tawm hauv lub Hoobkas?
Cov kav hlau hlau tau dhau los ua ntau yam NDTs ua ntej tawm hauv lub Hoobkas, xws li kev kuaj ultrasonic (UT), eddy tam sim no kuaj (ECT), sib nqus particle kuaj (MT), thiab kuaj hluav taws xob (RT), los tshuaj xyuas qhov chaw thiab subsurface defects.
Nyob rau hauv liquefied natural gas (LNG) tej yaam num, nyob rau hauv uas systems yog A333 Gr.6 steel yeeb nkab feem ntau siv?
Hauv cov haujlwm LNG,A333 Gr.6 steel yeeb nkabyog siv nyob rau hauv cryogenic LNG tsheb thauj mus los, cia, thiab ua tshuab.
Hauv kev lag luam tub yees, dab tsi xov xwm tuaj yeem siv ASTM A333 Qib 6 Tsawg Kub Kub Hlau Yeeb Nkab Siv los thauj?
ASTM A333 Qib 6 Tsawg Kub Kub Hlau yeeb nkabtuaj yeem siv los thauj ntau yam kev tshaj tawm cryogenic, suav nrog liquefied natural gas (LNG), kua nitrogen, thiab kua oxygen. Lawv tau siv dav hauv cov tshuab cryogenic, cov chaw cia txias, thiab cov kav dej thauj cov dej thiab cov pa roj ntawm sub-zero kub hauv kev lag luam tub yees.
Vim li cas ho tsis tuaj yeem siv cov pa roj carbon zoo tib yam hauv qhov chaw cryogenic?
Cov pa roj carbon zoo tib yam tsis tuaj yeem siv rau hauv qhov qis- qhov kub thiab txias ib puag ncig vim nws ua nkig thiab poob tawv tawv ntawm qhov kub thiab txias, ua rau nws muaj kev puas tsuaj loj.
Dhau li ntawm qhov kub thiab txias, dab tsi lwm qhov tseem ceeb tsim tsis yuav tsum tau xav txog thaum xaiv A333 Gr.6 steel yeeb nkab?
Dhau li ntawm qhov kub thiab txias, cov qauv tsim tseem ceeb rau kev xaivA333 Gr.6 steel yeeb nkabsuav nrog txhua yam khoom xws li lub zog tensile, lub zog tawm los, thiab kev cuam tshuam toughness, nrog rau lub cev qhov ntev xws li txoj kab uas hla thiab phab ntsa thickness. Lwm yam tseem ceeb uas yuav tsum xav txog suav nrog qhov project- cov kev cai tshwj xeeb, xws li kev kho saum npoo, txheej txheej, thiab vuam txheej txheem.
