20 # kua seamless steel yeeb nkab chaw tsim tshuaj paus
Cov yeeb nkab yeeb nkab yog ib hom yeeb nkab steel nrog hollow seem thiab tsis muaj vuam los ntawm qhov pib mus rau qhov kawg. Cov yeeb nkab steel muaj qhov hollow seem, uas yog dav siv los ua cov yeeb nkab rau kev xa dej, roj, nkev, roj, dej thiab qee yam khoom siv. Piv nrog cov khoom siv hlau xws li cov hlau puag ncig, cov yeeb nkab steel muaj tib yam dabtsi yog khoov thiab torsional lub zog thiab lub teeb yuag. Nws yog ib qho kev lag luam steel hlau. Nws yog dav siv nyob rau hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li roj laum yeeb nkab, tsheb sib kis ncej, tsheb kauj vab ncej thiab steel scaffold siv hauv kev tsim kho.
Cov yeeb nkab yeeb nkab yog cov yeeb nkab tshwj xeeb siv los thauj cov xov xwm nrog cov kua dej.
Ntxiv nrog rau cov kua dej xws li dej, roj thiab tshuaj, cov khoom siv xws li cov cement, nplej thiab pulverized thee kuj tuaj yeem ntws hauv qee qhov xwm txheej.
Cov kav dej muaj peev xwm ua tau los ntawm cov hlau, cov hlau tsis muaj hlau xws li tooj liab thiab titanium, thiab txawm tias cov khoom tsis yog xim hlau xws li yas.
Cov yeeb nkab dej yuav tsum muaj qhov hollow, tab sis nws tuaj yeem yog square, triangular lossis lwm yam duab. Qee cov cuab yeej siv yuav tsum siv cov yeeb nkab duab plaub vim muaj kev txwv, tab sis feem coob tseem siv cov yeeb nkab ncig. Lub voj voos kheej kheej muaj qhov tsawg tshaj plaws ncig / cheeb tsam sib piv hauv txhua ntu geometric, uas yog, qhov loj tshaj plaws sab hauv tuaj yeem tau txais nyob rau hauv cov xwm txheej ntawm kev siv cov khoom siv tib yam.
Cov yeeb nkab steel yog dav siv hauv kev thauj mus los hauv lub neej niaj hnub vim nws cov nqi qis thiab lub zog siab. Raws li nws cov txheej txheem ntau lawm, cov kav dej steel tau muab faib ua seamless steel kav thiab welded kav. Welded kav kuj tau muab faib ua high-frequency ncaj seam welded kav (ERW), kauv welded kav (SSAW), submerged arc welded kav (UOE), thiab lwm yam. Yav tas los, seamless steel kav yog ib txwm siv rau cov kav dej. Nrog rau kev txhim kho thiab kev vam meej ntawm cov khoom siv science, kev tsim cov cuab yeej technology thiab cov khoom siv hauv tsev, cov kav dej welded tau tsim zoo heev. Welded yeeb nkab muaj qhov zoo ntawm phab ntsa thickness uniformity, siab precision, tsawg zog noj thiab siab ntau lawm efficiency tshaj seamless yeeb nkab. Yav dhau los, yuav luag 100% ntawm cov yeeb nkab seamless tau siv rau cov roj thiab cov kav xa hluav taws xob (API tus qauv). Niaj hnub no, ntau tshaj li 95% ntawm lawv tau hloov los ntawm welded yeeb nkab nyob rau hauv lub tebchaws United States, Nyiv thiab European tsim lub teb chaws.
① Feem ntau, qhov kev pabcuam kub ntawm cov raj boiler yog qis dua 450 ℃, thiab cov raj hauv tsev feem ntau yog ua los ntawm No.
②Kev kub siab boiler raj feem ntau yog nyob rau hauv qhov kub thiab txias txias. Cov hlab yuav oxidized thiab corroded nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab chav. Cov yeeb nkab steel yuav tsum muaj lub zog ntev, siab tiv thaiv oxidation thiab corrosion kev ua tau zoo thiab kev ruaj ntseg zoo.
