Qhov sib txawv ntawm ABS EQ70 thiab CCS EQ70 steel phaj

ABS EQ70 thiab CCS EQ70 yog ob qho tib si ntxiv - siab - lub zog quenched thiab tempered steel phaj tshwj xeeb tsim los rau cov kev xav tau tshaj plaws hauv hiav txwv thiab ntug dej hiav txwv, tshwj xeeb tshaj yog cov uas yuav tsum tau muaj zog heev ntawm qhov kub thiab txias. Lawv tau ntawv pov thawj los ntawm ob lub koom haum kev faib loj loj-ABS (American Bureau of Shipping) thiab CCS (China Classification Society)- thiab sawv cev rau qib siab dua nyob rau hauv 70 kgf / mm² lub zog chav kawm, tsim rau cov qauv ua haujlwm hauv qhov chaw txias heev.

ABS Qib EQ70 tau lees paub los ntawm American Bureau of Shipping. Lub npe "EQ70" qhia qhov tsawg kawg nkaus lub zog ntawm 690 MPa (100 ksi) thiab lub zog tensile ntau ntawm 770-940 MPa (112-136 ksi). Tus "E" qhia txog Charpy V-notch cuam tshuam qhov ntsuas kub ntawm -40℃(-40℃F), yuav tsum muaj lub zog nruab nrab ntawm 41J (transverse) lossis 62J (ntev). Cov phaj no yog tsim los siv cov txheej txheem quenched thiab tempered (QT) kom ua tiav lawv qhov tshwj xeeb ua ke ntawm lub zog thiab tawv. Cov ntawv thov muaj xws li offshore drilling rigs, platforms, jack-up rig ob txhais ceg, nkoj hulls, floating ntau lawm cia thiab offloading nkoj (FPSOs), thiab tseem ceeb marine lug xav tau superior zog thiab durability nyob rau hauv hnyav ib puag ncig.

CCS Qib EQ70 tau lees paub los ntawm Tuam Tshoj Classification Society thiab ua haujlwm ncaj qha rau ABS EQ70 hauv Suav kev faib tawm. Raws li kev faib tawm hauv zej zog cov qauv, CCS EQ70 qhia cov cuab yeej cuab tam zoo ib yam nrog nws cov khoom siv ABS: yam tsawg kawg nkaus lub zog ntawm 690 MPa thiab tensile zog ntawm 770-940 MPa. Nws belongs rau tib tsev neeg cov khoom xws li AQ70, DQ70, EQ70, thiab FQ70 series rau nkoj tsim thiab offshore daim ntaub ntawv, nrog rau txhua tsab ntawv sawv cev rau qhov sib txawv ntawm qhov ntsuas kub. Zoo li ABS EQ70, CCS EQ70 xav tau Charpy qhov kev ntsuam xyuas ntawm -40℃nrog cov kev xav tau ntawm lub zog zoo sib xws.

Qhov txawv tseem ceeb:
Qhov tseem ceeb ntawm qhov sib txawv ntawm ob qib no yog nyob rau hauv lawv daim ntawv pov thawj txoj cai thiab cov txheej txheem tswj kom zoo. ABS EQ70 ua raws li American Bureau of Shipping cov cai thiab tau lees paub thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv cov haujlwm uas yuav tsum tau muaj ntawv pov thawj ABS rau cov ntug dej hiav txwv thiab cov nkoj uas tau los rau ABS-cov nkoj nkoj. CCS EQ70 ua raws li Tuam Tshoj Classification Society cov cai thiab feem ntau tau teev tseg rau cov qauv sab nrauv tsim hauv Suav nkoj nkoj lossis rau cov haujlwm hauv Suav kev faib tawm.

Los ntawm kev pom kev, cov hlau no suav tias yog hloov pauv tau, thiab cov tuam txhab loj tuaj yeem tsim cov ntawv pov thawj los ntawm ob lub zej zog ib txhij. Qhov kev xaiv ntawm lawv feem ntau yog txiav txim siab los ntawm tus chij xeev ntawm lub nkoj, kev nyiam ntawm nkoj nkoj, lossis cov kev xav tau tshwj xeeb. Ob qib yuav tsum tau muab nrog daim ntawv pov thawj zeb xeem (MTC) bearing kev faib pawg neeg soj ntsuam kev kos npe thiab tuaj yeem tsim nrog los ntawm - cov khoom tuab (Z25, Z35) txhawm rau txhim kho kev tiv thaiv lamellar tearing hauv cov pob qij txha hnyav heev.
