Txuj ci raj steel chev

Raj steel chev
Yeeb nkab steel phaj yog ua los ntawm cov hlau phaj welded ua ke, muab faib ua tus longitudinal weld yeeb thiab ob tug kauv weld steel yeeb nkab.
Cov longitudinal weld yeeb nkab raug rau lub chaw siv, lossis delegate zauv cog manufacturing, kws hlau cog ntau lawm. Q235A steel khoom, 10, 20th, 16Mn, 20G, specifications taub nominal 200 txog 3000 hli, ntau 4000 hli, ntsa thickness li ntawm 4 ~ 16 hli. 200 ~ 900 hli ib raj ntev ntawm 6.4m hli nominal taub; nominal taub 1000 tauj txog 3000 hli 4.8M. daim ntawv thov kub: Q235A-15 ~ 300℃, 10, 20th, 16Mn, 20 G,-40 ~ ℃ 450, yeej tsis muaj feem xyuam rau ntau yam tsawg-voltage.
Muab kauv weld steel yeeb, yeeb nkab steel manufacturing, Q235A, 16Mn. specifications li ntawm nominal txoj kab uas hla 200 cov ntaub ntawv txog 700 hli, cov phab ntsa 7 ~ 10 hli, ib cag kwj dej 8 ~ 18m. daim ntawv thov kub: Q235A-15 ~ 300℃, 16Mn-40 ~ 450℃, kev khiav hauj lwm siab: Q235A 2.5MPa, 16Mn los 4MPa.
Longitudinal weld yeeb thiab kauv weld steel yeeb, siv tsheb thauj mus los uas tsis tshua muaj siab tsis corrosive nruab nrab sov li, xws li muaj-voltage underground circulating dej, ncu, roj, thiab cov roj thiab roj. Muab kauv weld steel yeeb nkab tib yeeb nkab ntev, tsim tshwj xeeb tshaj yog rau cov tsheb thauj mus los ntev distance pipeline.
Raws li peb tes num yuav tsum, muaj cov ncaj leeg phaj welded stainless hlau, yuav dov rau ntawm cov chaw siv, lub Hoobkas tsis ua. Siv cov ntaub ntawv no 1Cr18Ni9Ti phaj. Specifications nominal txoj kab uas hla ntawm 200 txog 1000 hli, taub nominal phab ntsa thickness ntawm 200 ~ 400 hli yog 4 hli, cov thickness txog li 700 nominal ~ 1000 hli 6 ~ 8 mm hauv txoj kab uas hla, ntev ib qho kwj dej cag yog 4.5M. muaj kub ntau yam thiab kis nruab nrab uas tsis tshua muaj siab stainless hlau raj.
