Dab tsi yog qhov txawv ntawm ABS DQ47 thiab ABS DQ51?

Jan 27, 2026 Tso lus

ABS DQ47 thiab ABS DQ51 yog siab -lub zog quenched thiab tempered (DQ) steel qib tsim los ntawm American Bureau of Shipping (ABS) rau shipbuilding, tshwj xeeb tshaj yog nyob rau hauv offshore platforms thiab structural engineering.. Qhov sib txawv tseem ceeb yog qib siab zog, nrog DQ51 muab cov txiaj ntsig zoo dua piv rau DQ47, tsim los rau cov dej tob lossis hnyav dua.

Lus Cim: Lub Zog 1 yog qhov kev ntsuas cuam tshuam, Lub Zog 2 yog qhov ntev

Yield zog:ABS DQ51 muab qhov tsawg kawg nkaus tawm lub zog ntawm 500 MPa, siab dua 470 MPa + yam tsawg kawg nkaus xav tau rau DQ47, ua rau nws tsim nyog rau cov ntawv thov xav tau kev tiv thaiv ntau dua rau deformation.

Daim ntawv thov:Ob leeg siv rau kev pabcuam hnyav, tab sis ABS EQ51 (sib npaug rau DQ51 nrog cov kev xav tau siab dua) feem ntau yog siv rau hauv qhov tseem ceeb ntawm ntug dej hiav txwv drilling platforms thiab tshwj xeeb shipbuilding.

Qib sib npaug:Thaum DQ51 sib npaug rau qib zoo li CCSEH500 thiab BVEH500, DQ47 sawv cev qis dua, tseem tseem siab -lub zog, qib.
