Warranty ntawm tiag boiler raj manufacturers
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.
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 raj rau kev kub siab boilers, sab nraud txoj kab uas hla 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 hlau.
(1) Gb3087-2008 seamless steel raj rau qis thiab nruab nrab siab boilers. Txoj kev kuaj tshuaj muaj pes tsawg leeg yuav tsum ua raws li qhov cuam tshuam ntawm gb222-84 thiab gb223 txoj hauv kev rau tshuaj xyuas cov hlau, hlau thiab hlau.
(2) GB5310-2008 seamless steel raj rau kev kub siab boilers. Txoj kev kuaj tshuaj muaj pes tsawg leeg yuav tsum ua raws li cov khoom siv hauv gb222-84, cov txheej txheem rau kev tshuaj xyuas tshuaj ntawm hlau, hlau thiab hlau thiab gb223 txoj hauv kev rau tshuaj xyuas cov hlau, hlau thiab hlau.
(3) Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov kav dej boiler steel yuav tsum raug tshuaj xyuas raws li cov qauv tsim nyog tau teev tseg hauv daim ntawv cog lus (1) Cov qib zoo carbon steel qauv suav nrog 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.
