Dab tsi yog qhov tseem ceeb weld seam ntawm ib tug kauv welded yeeb nkab?
Lub ntsiab weld seam ntawm akauv welded yeeb nkabyog kab pheeb ces kaum kauv weld seam raws qhov ncig ntawm lub cev yeeb nkab. Nws yog tsim los ntawm welding lub steel sawb ntawm nws ntug raws li nws yog mob thiab pub rau hauv lub tshuab. Qhov kauv weld seam no yog nws qhov tshwj xeeb, sib txawv ntawm cov kav dej nrog ncaj longitudinal weld seams.
Hauv cov txheej txheem tsim khoom ntawm S235 JR kauv welded yeeb nkab, puas yog cov welds sab hauv thiab sab nrauv feem ntau ua ib txhij?
Tsis yog, lub puab thiab sab welds ntawmkauv welded kavfeem ntau tsis ua ib txhij; lawv feem ntau ua raws li ob kauj ruam ywj pheej tom qab pib tsim thiab ua ntej- vuam. Lub steel sawb yog thawj zaug ua ntej-welded rau ntawm lub tshuab ua cov kauv thiab tom qab ntawd txav mus rau qhov kawg vuam cov cuab yeej rau ob sab hauv thiab sab nrauv welds.
Yuav ua li cas tsis yog -kev kuaj kev puas tsuaj (NDT) feem ntau ua ntawm S235 JR kauv welded kav?
Tsis yog -kev kuaj kev puas tsuaj (NDT) ntawmS235 JR kauv welded kavFeem ntau siv kev sib xyaw ua ke ntawm kev tshuaj xyuas saum npoo thiab cov txheej txheem tshuaj ntsuam xyuas kom ntseeg tau tias qhov zoo ntawm vuam. Kev kuaj ultrasonic (UT) thiab kev kuaj hluav taws xob (RT) yog cov kev siv ntau tshaj plaws los kuaj xyuas qhov tsis xws luag sab hauv, thaum kuaj cov hlau nplaum sib nqus (MPI) thiab kev tshuaj xyuas qhov muag yog cov qauv kev tshuaj xyuas saum npoo.
Cov txheej txheem European twg S235 JR cov khoom siv feem ntau ua raws?
S235 JRcov khoom ua raws li European tus qauv EN 10025-2. Cov qauv no qhia txog cov txheej txheem kev xa khoom rau cov hlau tsis yog hlau. S235 JR qhia txog cov qauv hlau nrog qhov tsawg kawg nkaus lub zog ntawm 235 MPa thiab lav toughness ntawm 20 degree.
Cov qauv khoom dab tsi feem ntau yog siv rau cov kav dej welded?
Common khoom qauv raukauv welded kavsuav nrog: API 5L rau roj thiab roj, thiab ASTM A53 thiab ASTM A106 rau kev siv dav dav thiab kev siv tshuab.
