1.Seamless steel yeeb nkab: seamless yeeb nkab yog ib hom steel ntev nrog ntu hollow thiab tsis muaj seam nyob ib puag ncig. Cov yeeb nkab hlau muaj ntu hollow, uas yog siv dav rau thauj cov kua, xws li roj, nkev nkev, nkev, dej thiab qee yam khoom siv khov kho. Piv nrog cov hlau khov xws li cov hlau puag ncig, cov yeeb nkab tsis sib haum muaj tib yam khoov thiab ua kom muaj zog thiab hnyav dua. Nws tau siv dav hauv kev tsim khoom ntawm cov khoom siv thiab cov khoom siv kho tshuab, xws li roj av laum yeeb nkab, tsheb sib kis, tsheb kauj vab ncej thiab hlau scaffold siv hauv kev tsim kho. Nws tuaj yeem txhim kho cov khoom siv tus nqi, ua kom yooj yim rau cov txheej txheem tsim khoom, txuag cov ntaub ntawv thiab ua lub sijhawm los ntawm kev siv cov yeeb nkab tsis sib xws los tsim cov khoom sib txuas, xws li lub nplhaib sib dhos, lub tes tsho, thiab lwm yam. riam phom. Chim thiab chim yog ua los ntawm cov raj hlau. Raws li cov duab ntawm cheeb tsam hla ntu, cov kav hlau tuaj yeem muab faib ua cov yeeb nkab puag ncig thiab cov yeeb nkab tshwj xeeb. Vim tias thaj tsam ntawm lub voj voos yog qhov loj tshaj plaws nyob hauv ib puag ncig ib puag ncig, cov kua ntau tuaj yeem thauj tau los ntawm cov raj raj. Ib qho ntxiv, thaum lub nplhaib ntu ua haujlwm sab hauv lossis sab nraud radial siab, lub zog muaj ntau dua qub. Yog li ntawd, feem ntau cov raj tsis sib thooj yog cov raj hloov pauv, uas tau muab faib ua kub dov thiab txias txias. Cov khoom siv sib xws: 20 #, 45 #, Q345, 20g, 20Cr, 35CrMo, 40Cr, 42CrMo, 12CrMo, 12Cr1MoVG, 15CrMoG, thiab lwm yam; Stainless hlau series yog ib hom hollow ntev puag ncig cov hlau, uas tau siv dav hauv roj av, tshuaj lom neeg, kev kho mob, zaub mov, kev lag luam teeb pom kev zoo, cov cuab yeej siv kho tshuab thiab lwm yam kev lag luam thiab cov khoom siv ua haujlwm. Ib qho ntxiv, thaum khoov thiab ua kom lub zog zoo ib yam, qhov hnyav yog qhov sib dua, yog li nws kuj tseem siv dav hauv kev tsim cov khoom siv tshuab thiab cov qauv tsim vaj tsev. Kuj tseem siv rau rooj tog, khoom siv hauv chav ua noj, thiab lwm yam, cov khoom siv sib xws: 201, 304, 316, 316L, 310, 310S, thiab lwm yam.
2. Cov phaj hlau: nws yog cov hlau tiaj tiaj nrog cov hlau yaj thiab nias tom qab txias. Nws yog tiaj thiab cov duab plaub, thiab tuaj yeem ncaj ncaj dov lossis txiav los ntawm cov hlau dav. Hlau phaj tau muab faib ua kub dov thiab txias txias raws li dov. Raws li cov tuab tuab ntawm cov phaj hlau, cov phaj hlau nyias nyias <4 hli (qhov thinnest 0.2 hli), phaj tuab tuab tuab 4 ~ 60 hli, phaj tuab tuab tuab 60 ~ 115 hli. Qhov dav ntawm daim ntawv yog 500-1500 hli; Qhov dav ntawm phaj tuab yog 600-3000 mm. Raws li hom hlau, muaj cov hlau zoo ib yam, cov hlau zoo, cov hlau tsis muaj hlau, lub caij nplooj ntoo hlav, cov hlau tsis muaj steel, cov cuab yeej hlau, cov hlau tiv tshav kub, cov hlau, cov hlau silicon thiab cov ntawv hlau ntshiab Raws li kev siv txuj ci, muaj cov phom phom phom, phaj txha hniav laus, phaj phom, thiab lwm yam; Raws li txheej txheej, muaj cov ntawv galvanized, tinplate, phaj txhuas, yas yas sib xyaw ua ke, thiab lwm yam khoom siv: Q235, 16Mn (q355b), 20 #, 45 #, 65Mn, 40Cr, 42CrMo, 304, 201, 316 , lwm yam
3. Welded yeeb nkab: welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm cov phaj hlau lossis kab txaij tom qab curling thiab sib sau, nrog rau qhov dav dav ntev txog 6 meters. Cov txheej txheem tsim khoom ntawm cov yeeb nkab txuas hlau yog qhov yooj yim, kev tsim khoom tau zoo, ntau yam thiab cov yam ntxwv tshwj xeeb yog ntau dua, cov cuab yeej siv peev txheej tsawg dua, tab sis lub zog dav yog qis dua cov yeeb nkab hlau tsis xeb. Welded steel yeeb nkab tau muab faib ua cov yeeb nkab txuas ncaj thiab muab kauv welded yeeb nkab raws li daim ntawv weld. Kev faib tawm los ntawm cov txheej txheem tsim khoom: txheej txheem kev faib tawm - cov yeeb nkab sib txuas, cov yeeb nkab txuas tsis kam, (siab ntau, tsawg zaus) roj txuas cov yeeb nkab, cua sov txuas cov yeeb nkab. Kev siv txoj hlua ncaj ncaj siv rau txoj kab uas hla me me txuas cov yeeb nkab, thaum muab kauv vuam siv rau txoj kab uas hla loj txuas cov yeeb nkab; Raws li qhov kawg ntawm cov yeeb nkab steel, nws tuaj yeem muab faib ua cov yeeb nkab txuas thiab cov duab tshwj xeeb (square, duab plaub, thiab lwm yam) welded yeeb nkab; Raws li cov ntaub ntawv sib txawv thiab siv, nws tuaj yeem muab faib ua kuv cov kua dej xa cov kav hlau txuas, cov kua qis qis xa cov yeeb nkab galvanized welded steel yeeb nkab, txoj siv thauj khoom rau cov menyuam txuas cov yeeb nkab steel, thiab lwm yam Ncaj txuas cov yeeb nkab tsim cov txheej txheem yog yooj yim, ua haujlwm tau zoo, tus nqi qis, kev txhim kho sai. Lub zog ntawm kauv welded yeeb nkab feem ntau siab dua li ntawm cov yeeb nkab txuas ncaj. Nws tuaj yeem siv los tsim cov kab uas hla loj dua cov yeeb nkab txuas nrog qhov nqaim nqaim, thiab nws kuj tseem tuaj yeem siv los tsim cov kab sib txawv ntawm cov yeeb nkab txuas nrog tib qhov dav dav. Tab sis piv nrog tib qhov ntev ntawm cov yeeb nkab ncaj ncaj, qhov ntev txuas ntxiv los ntawm 30 ~ 100%, thiab kev tsim khoom nrawm dua. Cov kab loj loj lossis tuab cov yeeb nkab txuas feem ntau yog ua los ntawm cov hlau hlau ncaj qha, thaum cov yeeb nkab me me thiab cov phab ntsa nyias cov yeeb nkab tsuas yog yuav tsum tau welded ncaj qha los ntawm cov hlua hlau. Tom qab ntawv yooj yim polishing, xaim duab yog OK. Txhawm rau txhawm rau txhim kho kev txhim kho corrosion ntawm cov yeeb nkab steel, cov yeeb nkab dav dav (cov yeeb nkab dub) tau galvanized. Muaj ob hom galvanized steel yeeb nkab, kub dip galvanizing thiab electro galvanizing. Lub thickness ntawm kub-dip galvanizing yog tuab, thiab tus nqi ntawm electro galvanizing yog tsawg. Cov khoom siv sib txuas ntawm cov yeeb nkab txuas yog: Q235A, Q235C, Q235B, 16Mn, 20Mn, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, thiab lwm yam.
4. Coiled yeeb nkab: coiled yeeb nkab tau cog lus rau kev tsim ntau yam ntawm cov yeeb nkab coiled thiab steel penstocks nrog ib puag ncig cov nqaws thiab cov kab sib txuas ntev, thiab tau hloov pauv raws lub hauv paus ntawm cov lus qhia tshwj xeeb thiab cov qauv ntawm cov tsoos coiled yeeb nkab khoom. Kev ua haujlwm ntawm kev nce qhov ntsuas ntawm cov raj xa khoom los ntawm 30% ua rau qhov sib txawv uas cov khoom siv ib txwm tsis tuaj yeem tsim. Nws tuaj yeem tsim cov kav hlau nrog txoj kab uas hla ntau dua 400 thiab phab ntsa tuab ntawm 8-100 hli. Cov yeeb nkab coiled tau siv dav hauv roj av, tshuaj lom neeg, xa cov pa nkev, tso dej thiab dej hauv nroog, cua sov, muab roj thiab lwm yam dej num. Cov ntaub ntawv tseem ceeb yog Q235A, Q345B, 20, 45, 35cimo, 42cimo, 16Mn, thiab lwm yam
