Cov pa roj carbon steel yeeb nkab, cov khoom siv dav siv hauv kev lag luam, ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li roj av, chemical engineering, thiab kev tsim kho. Cov pa roj carbon steel yeeb nkab feem ntau tau faib ua ob hom:seamless steel yeeb nkabthiabwelded steel yeeb nkab.
Nyob rau hauv cov nqe lus ntawm ntau lawm txheej txheem thiab cov qauv, seamless steel yeeb nkab yog tsim los ntawm ib tug rolling los yog extrusion, tsis muaj welded seams. Nws muaj tag nrho lub zog thiab toughness, tuaj yeem tiv taus siab dua thiab kub, thiab tsim nyog rau cov ntawv thov kom nruj cov yeeb nkab kev nyab xeeb.
Welded steel yeeb nkab, ntawm qhov tod tes, yog tsim los ntawm coiling thiab vuam steel daim hlau, nrog ib lossis ntau qhov welds. Thaum qhov no muaj kev ua haujlwm siab thiab tus nqi qis, nws qhov kev ua tau zoo nyob rau hauv kev kub siab thiab huab cua ib puag ncig yog me ntsis qis dua cov yeeb nkab seamless.
Rau seamless steel yeeb nkab, Q235 thiab A36 yog qib nrov. Q235 steel yeeb nkab yog feem ntau siv carbon structural steel qib hauv Suav teb. Nrog lub zog tawm los ntawm 235 MPa, nws muaj cov khoom siv zoo heev thiab kev ua haujlwm ntawm tus nqi pheej yig. Nws yog dav siv hauv kev tsim cov qauv kev txhawb nqa, cov kav dej uas tsis tshua muaj siab, thiab lwm yam kev siv, xws li cov kav dej hauv tsev thiab cov hlau thav duab ntawm cov vaj tsev zoo tib yam.
A36 carbon steel yeeb nkabyog US standard qib. Nws lub zog tawm los zoo ib yam li Q235, tab sis nws muaj lub zog tensile zoo dua thiab cuam tshuam rau lub zog. Nws yog dav siv nyob rau hauv cov kav dej uas tsis tshua muaj siab hauv cov tshuab tsim khoom thiab cov roj ntau lawm, xws li cov khoom siv tshuab me me thiab cov kav dej tsis tshua muaj siab hauv cov roj av.
Rau welded steel yeeb nkab,Q235 welded steel yeeb nkabkuj yog qib nrov. Vim nws cov nqi qis thiab kev ua haujlwm vuam zoo heev, nws feem ntau yog siv rau hauv lub nroog cov pa xa hluav taws xob thiab cov dej tsis tshua muaj zog. A36 welded yeeb nkab, ntawm qhov tod tes, feem ntau yog siv rau hauv cov kav dej uas tsis tshua muaj siab nrog qee qhov yuav tsum tau muaj zog, xws li cov khoom siv hluav taws xob tsawg hauv cov kav dej hauv cov nroj tsuag tshuaj me me.

| Impact Toughness Requirements | A -40 ° C cuam tshuam kev xeem tsuas yog xav tau rau qee qib (piv txwv li, Q235D); tsis muaj qhov yuav tsum tau muaj rau cov qhab nia. | Qhov yuav tsum tau muaj: -18 ° C cuam tshuam kev xeem (ib feem qauv); low-temperature toughness me ntsis zoo dua li cov qauv Q235 qib |
| Main Application Scenarios | Kev tsim kho pej xeem (cov qauv hlau, kev txhawb nqa), cov kav dej tsis tshua muaj siab / roj av, thiab cov khoom siv dav dav | Mechanical manufacturing (cov khoom me me thiab nruab nrab), cov kav dej tsis tshua muaj siab, cov kav dej tsis tshua muaj siab |
Zuag qhia tag nrho, seamless thiab welded steel kav txhua tus muaj lawv tus kheej zoo. Thaum yuav khoom, cov neeg siv khoom yuav tsum xav txog lub siab thiab qhov kub thiab txias ntawm daim ntawv thov tshwj xeeb, nrog rau lawv cov peev nyiaj, thiab xaiv cov qib tsim nyog, xws li Q235 lossis A36, kom ntseeg tau tias qhov project zoo thiab kev nyab xeeb.
