Elongation
Lub elongation sib raug rau txoj kev tsim cov raj yog qhia hauv Table 4.
Txawm li cas los xij, thaum qhov ntsuas tensile tau ua tiav ntawm Test Piece No. 12 lossis Test Piece No.5 coj los ntawm lub raj hauv qab 8 hli hauv phab ntsa tuab, qhov elongation yuav tsum ua raws li Table 5.
Flattening Resistance
Muab cov ntawv xeem ntawm qhov kub zoo tib yam (5 ° C mus rau 35 ° C) ntawm ob daim hlau tiaj tus thiab compress kom flatten kom txog thaum qhov kev ncua deb ntawm daim hlau H yuav sib npaug los yog me dua li tus nqi teev tseg hauv Table 3, tom qab ntawd tshuaj xyuas cov kab nrib pleb ntawm lub xeem daim.
Muab cov welds ntawm kuj welded steel yeeb nkab thiab taub qab welded steel yeeb nkab kom cov kab nruab nrab ntawm cov yeeb nkab thiab cov vuam yog perpendicular rau cov kev taw qhia ntawm compression.
Khoov Test
Khoov daim ntawv xeem nyob ib ncig ntawm lub tog raj kheej ntawm qhov kub thiab txias (5 ° C mus rau 35 ° C) ntawm lub kaum sab xis ntawm lub kaum sab xis tsis tsawg tshaj li qhov tsawg kawg nkaus lub kaum sab xis uas tau teev tseg hauv Daim Ntawv 3, thiab nrog lub vojvoog sab hauv tsis ntau tshaj qhov siab tshaj plaws hauv lub vojvoog tau teev tseg hauv Table 3, thiab tshuaj xyuas cov khoom kuaj rau cov kab nrib pleb.
Rau kev ntsuam xyuas hluav taws xob tsis kam welded steel raj thiab taub qab-welded steel raj, tso cov khoom xeem xws li qhov vuam yog 90 ° C los ntawm qhov chaw sab nraud ntawm qhov khoov.
Lwm Cov Kev Xeem
Kev ntsuam xyuas hydrostatic, kev ntsuam xyuas tsis muaj kev puas tsuaj ntawm welds, lossis lwm yam kev sim yuav tsum tau pom zoo ua ntej ntawm cov kev xav tau.
