Nyob rau hauv cov nqe lus ntawm ntau lawm technology, seamless steel kav yog tsim los ntawm kub dov, perforated los ntawm round steel, thiab qhov loj ntawm qhov kub thiab txias, ua rau tsis raug sab nraud txoj kab uas hla tswj thiab loj phab ntsa thickness sib txawv; thaum ERW steel kav yog ua los ntawm kub dov strip coils, thiab yog tsim los ntawm txias dabtsi yog khoov thiab vuam txheej txheem, nrog meej txheej txoj kab uas hla tswj thiab zoo phab ntsa thickness uniformity.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo yam ntxwv, lub sab nraud txoj kab uas hla thiab phab ntsa thickness tolerances yog txawv. Sab nraud txoj kab uas hla ntawm seamless X52 kav dej yog qhov nyuaj los tswj kom raug, thiab phab ntsa thickness sib txawv yog loj. Cov chav nyob qib siab tsuas tuaj yeem tswj tau hauv ±5-10% t, thaum ERW X52 cov kav dej tuaj yeem tswj cov phab ntsa thickness kam rau ua nyob rau hauv 0.05mm. Hauv kev sim tensile, lub zog ntawm seamless steel kav yog nyob rau sab sauv txwv, thiab cov yas yog nyob rau hauv qis qis. Lub zog Performance index ntawm X52 ERW kav yog zoo heev thiab cov plasticity Performance index tshaj tus qauv los ntawm 33.3%. Cov ntaub ntawv raw ntawm ERW steel kav yog dov nrog siab precision ntawm kev tswj cua txias thiab dov, kev ua haujlwm zoo, thiab dav thiab tuab nruam casting billets. Lub nto solidification txheej ntawm nplua nplej yog tuab, lub koom haum yog ntom, thiab cov grain loj yog uniform. Qhov kev ntsuam xyuas los tiv thaiv kev sib tsoo pom tau tias ERW steel kav muaj qhov ua tau zoo los tiv thaiv kev sib tsoo zoo dua li cov kav hlau tsis sib haum vim lawv qhov sib xws ntawm cov phab ntsa tuab thiab ovality, thiab lawv cov khoom siv niam txiv cuam tshuam rau qhov hnyav yog ob peb zaug ntawm seamless steel kav.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, X52 seamless steel kav feem ntau yog siv nyob rau hauv high-pressure pipelines rau roj thiab natural gas vim lawv siab zog thiab siab tsis kam; X52 ERW steel kav yog tsim rau cov tsev, txuas hniav thiab lwm yam khoom siv uas tsis xav tau lub zog siab tab sis yuav tsum muaj ntau lawm vim lawv cov yas zoo thiab tus nqi qis.
