Hauv kev lag luam niaj hnub no hauv dej hiav txwv thiab ntug dej hiav txwv, kev xaiv cov hlau tsim kho kom zoo yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm lub nkoj, kev ua tau zoo, thiab kev ruaj khov mus sij hawm ntev. Ntawm cov hlau tsim kho nkoj uas siv dav tshaj plaws yogAH36, DH36, thiab EH36Cov qib no yog qhov tseem ceeb rau cov qauv hull, decks, offshore platforms, thiab cov ntawv thov marine siab. Txawm hais tias lawv muaj ntau yam zoo sib xws, txhua qib muaj cov kev xav tau sib txawv, ua rau lawv haum rau cov chaw ib puag ncig thiab cov xwm txheej ntawm qhov project.

Raws li cov qauv kev tsim nkoj thoob ntiaj teb txuas ntxiv mus thiab cov koom haum faib tawm nruj dua lawv cov cai, cov chaw tsim nkoj xav tau cov ntaub ntawv uas tuaj yeem muab kev ua tau zoo hauv qab qhov kub thiab txias sib txawv thiab cov xwm txheej cuam tshuam siab. Cov neeg muab khoom ua thawj coj xws lisakysteeltxhawb nqa cov neeg tsim nkoj thoob ntiaj teb los ntawm kev muab AH36, DH36, thiab EH36 steel phaj nrog kev taug qab tag nrho, kev pom zoo kev faib tawm, thiab kev sib xws siab.

Tsab xov xwm no muab kev sib piv ntawm AH36 vs DH36 vs EH36, tshuaj xyuas cov khoom siv kho tshuab, kev ua tau zoo, cov xwm txheej siv, thiab kev taw qhia txog qib twg zoo tshaj plaws rau cov haujlwm tsim nkoj sib txawv.

Nkag Siab Txog Cov Qib Muaj Zog Marine: AH36, DH36, EH36

AH36, DH36, thiab EH36 yog cov hlau ua nkoj muaj zog dua uas tau muab faib ua pawg hauv ASTM A131 thiab tau ntawv pov thawj los ntawm ABS, LR, DNV, BV, CCS, thiab lwm lub koom haum. Lawv sib koom tib yamqhov tsawg kawg nkaus ntawm cov zis zog ntawm 355 MPa, ua rau lawv tsim nyog rau cov ntawv thov kev tsim kho uas xav tau.

Qhov sib txawv tseem ceeb ntawm cov qib no yogkev cuam tshuam tawvntawm qhov kub sib txawv:

  • AH36Kuaj ntawm 0°C

  • DH36Kuaj ntawm -20 ° C

  • EH36Kuaj ntawm -40 ° C

Qhov kub qis dua qhia tau tias muaj zog dua thiab tiv taus kev tawg yooj yim dua, qhov tseem ceeb rau qhov chaw txias lossis huab cua hnyav.

Kev Sib Piv Txog Cov Khoom Siv Kho Tshuab
