Yog vim li cas X70 Yuav tsum tau Closer Mill Scrutiny
Ntawm X70, yeeb nkab kev ua tau zoo nyob ntawm kev tswj microstructure, tsis yog tshuaj lom neeg muaj pes tsawg leeg ntsib qhov tsawg kawg nkaus spec. Cov neeg yuav khoom yuav tsum tau thov tsis tsuas yog daim ntawv pov thawj zeb tab sis kuj tseem vuam seam hardness daim ntawv ntsuam xyuas thiab poob - hnyav kua muag kuaj (DWTT) cov ntaub ntawv uas tau teev tseg, vim hais tias cov no ncaj qha qhia tsis kam mus rau nkig tawg propagation - ib qho tseem ceeb tsis ua hauj lwm hom nyob rau hauv siab - zog, siab - siab gas pipelines. Kev xa khoom X70 los ntawm lub zeb yam tsis muaj ntaub ntawv pov thawj hauv qib siab dua -qib ERW ntau lawm ua rau muaj kev pheej hmoo ntau dua li kev nrhiav cov qib qis.
Cov lus nug nquag nug (FAQ)
Q: Dab tsi ua rau X70 nyuaj rau kev tsim khoom dua li qib qis?
A: Ua tiav X70's yield zog thaum tswj kom txaus toughness yuav tsum tau microalloying thiab tswj dov ntawm lub hauv paus steel, ntxiv rau nruj tswj induction vuam cua sov input kom tsis txhob embrittlement nyob rau hauv lub tshav kub - cuam tshuam cheeb tsam. Tsis yog tag nrho ERW mills muaj peev xwm tsim tau rau qib no.
Q: Puas yog DWTT (poob- hnyav kua muag kuaj) rau X70 yeeb nkab?
A: Nws feem ntau tau teev tseg rau X70 roj xa cov yeeb nkab, tshwj xeeb tshaj yog rau cov haujlwm cuam tshuam nrog kev tswj kev tawg, txawm tias qhov yuav tsum tau muaj tseeb nyob ntawm qhov project specification thiab kev khiav hauj lwm siab. Paub meej nrog koj tus kws ua haujlwm hauv pipeline seb nws puas siv tau rau koj qhov kev txiav txim.
Q: Dab tsi txoj kab uas hla yog siv tau rau X70 ERW yeeb nkab?
A: Thaum PSL1 muaj nyob rau hauv daim ntawv rau X65, feem ntau ntawm cov tiag tiag -lub ntiaj teb specifications yuav tsum tau PSL2 vim qhov yuav tsum tau muaj kev ntsuam xyuas thiab nruj nreem compositional tswj nyob rau hauv lub zog theem no.
Q: Tus nqi X70 piv rau X65 lossis X60 li cas?
A: X70 hais kom tus nqi them nqi ib tuj vim cov nqi microalloying thiab kev tswj cov txheej txheem nruj dua, tab sis tag nrho cov nqi sib piv yog nyob ntawm phab ntsa thickness txo qhov ua tiav ntawm qib siab dua - ib qhov project- tshwj xeeb phab ntsa thickness xam yog xav tau rau kev sib piv ncaj ncees.
