Kev piav qhia

A53 seamless steel yeeb nkab yog ib yam khoom ntawm American standard steel yeeb nkab, nyob rau hauv uas a53-a yog sib npaug rau domestic 10 # steel, a53-b yog sib npaug rau domestic 20 # steel, thiab a53-f yog sib npaug rau domestic Q235 khoom. Cov txheej txheem tseem ceeb ntawm A53 seamless steel yeeb nkab yog cov duab txias thiab kub dov. Qhov sib txawv tseem ceeb ntawm ob yog tias cov txheej txheem ntawm cov yeeb nkab txias-dov seamless steel yeeb nkab feem ntau nyuaj dua li qhov kub dov. Nyob rau hauv tsos, lub txias-dov seamless steel yeeb nkab yog luv dua li ntawm kub dov seamless steel yeeb nkab. Cov phab ntsa tuab ntawm cov yeeb nkab txias-dov seamless steel feem ntau me dua li cov yeeb nkab kub-dov seamless steel yeeb nkab, tab sis qhov saum npoo zoo li ci dua. Qhov saum npoo ntawm kub dov steel yeeb nkab yog ntxhib. Cov txheej txheem tseem ceeb ntawm cov khoom siv yog puag ncig lub raj tsis muaj → cua sov → perforation → peb yob cross dov, nruam dov los yog extrusion → yeeb nkab stripping → sizing (los yog txo) → txias → straightening → hydrostatic test (los yog flaw detection) → marking → warehousing. Kev suav cov qauv ntawm qhov hnyav ib 'meter' ntawm A53 seamless steel yeeb nkab: 0.02466 * phab ntsa thickness * (sab nraud txoj kab uas hla - phab ntsa thickness).

Kev kub siab seamless steel yeeb nkab thiab siab siab boiler yeeb nkab yog ib hom boiler yeeb nkab, teej tug mus rau qeb ntawm seamless steel yeeb nkab. Txoj kev tsim khoom yog tib yam li cov yeeb nkab seamless, tab sis muaj cov kev cai nruj rau cov qib steel siv hauv kev tsim cov yeeb nkab steel. Kev kub siab boiler raj feem ntau yog siv nyob rau hauv qhov kub thiab txias siab. Kev kub siab boiler raj feem ntau yog siv los tsim cov raj superheater, reheater raj, cua ducts, lub ntsiab chav boilers, thiab lwm yam ntawm high-pressure thiab ultra-high-pressure boilers.

A53 high pressure seamless steel pipe manufacturer

Tsawg thiab nruab nrab siab siab boiler raj gb3087-2008 thiab siab siab boiler raj GB5310-2008 yog high-quality carbon structural steel kub-kuav los tiag thiab txias drawn (dov) seamless steel hlab rau manufacturing superheated chav tubes, boiling dej raj ntawm qis thiab siab siab. boilers nrog ntau yam qauv thiab superheated chav tubes, cov pa luam yeeb loj, cov pa luam yeeb me me thiab arch bricks rau locomotive boilers. Seamless steel yeeb nkab rau cov qauv (GB / t8162-2008) yog seamless steel yeeb nkab rau cov qauv dav dav thiab cov qauv siv tshuab.

Specification thiab tsos zoo: GB5310-2008 seamless steel hlab rau siab siab boilers, txheej kab ntawm kub dov raj yog 22 ~ 530mm, thiab phab ntsa thickness yog 20 ~ 70mm. Cold drawn (txias dov) yeeb nkab muaj ib txoj kab uas hla ntawm 10 ~ 108mm thiab phab ntsa thickness ntawm 2.0 ~ 13.0mm.

Tshwj xeeb zoo li tus seamless steel yeeb nkab yog lub npe dav ntawm seamless steel yeeb nkab nrog rau lwm seem duab tshwj tsis yog cov yeeb nkab ncig. Raws li cov duab sib txawv thiab qhov loj ntawm cov yeeb nkab steel, nws tuaj yeem muab faib ua vaj huam sib luag thickness tshwj xeeb zoo li seamless steel yeeb nkab (code D), tsis sib xws phab ntsa thickness tshwj xeeb zoo li seamless steel yeeb nkab (code BD) thiab sib txawv txoj kab uas hla tshwj xeeb-puab. seamless steel yeeb nkab (code BJ). Tshwj xeeb zoo li tus seamless steel yeeb nkab yog dav siv nyob rau hauv ntau yam structural qhov chaw, cov cuab yeej thiab mechanical qhov chaw. Piv nrog cov yeeb nkab ncig, cov yeeb nkab tshwj xeeb feem ntau muaj lub sijhawm loj ntawm inertia thiab seem modulus, thiab muaj ntau dua dabtsi yog khoov thiab torsion tsis kam, uas tuaj yeem txo qhov hnyav ntawm cov qauv thiab txuag steel:

(1) Cov qib zoo carbon steel qauv muaj xws li 20g, 20mng thiab 25mng.

(2) Alloy structural steel qib: 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, thiab lwm yam.

(3) Ntxiv rau kev ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, 1Cr18Ni9 thiab 1cr18ni11nb boiler raj feem ntau siv hauv cov hlau tsis xeb hlau yuav tsum raug kuaj hydrostatic, flaring thiab flattening kuaj ib los ntawm ib qho. Cov yeeb nkab steel yuav tsum tau muab xa mus rau hauv qhov chaw kho cua sov.

Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj thiab decarburization txheej ntawm cov yeeb nkab steel tiav.
