ASTM A672 C70 Carbon Steel EFW yeeb nkab
Dab tsi yog cov khoom siv A672 C70 welded yeeb nkab?
Cov tshuaj muaj pes tsawg leeg ntawm ASTM A672 C70 welded steel yeeb nkab suav nrog qhov siab tshaj plaws ntawm 0.25 carbon, 0.98 manganese, 0.64 molybdenum thiab 0.45 silicon. Nws tso cai rau qee yam khoom siv xws li yield zog (Mpa) 37 thiab tensile zog (Mpa) 65.
ASTM A672 tus qauv qhia cov kev cai rau welded steel yeeb nkab rau faus los yog submerged kev pab cuam, suav nrog muab kauv seam submerged arc welded steel yeeb nkab thiab longitudinal seam submerged arc welded steel yeeb nkab. C70 yog qib nyob rau hauv tus qauv uas sawv cev rau cov khoom siv kho tshuab thiab tshuaj lom neeg muaj pes tsawg leeg rau cov kav hlau.
Qib C70 feem ntau yog hais txog qib siab zog ntawm cov yeeb nkab steel, uas yog, qhov kev ntxhov siab ntawm cov yeeb nkab steel pib ua rau cov yas deformation thaum raug rau qee qhov kev quab yuam sab nraud. C70 qhia tias cov yeeb nkab muaj lub zog tawm ntawm kwv yees li 485 MPa (kwv yees li 70 ksi). Ib txoj kev tsim khoom uas seams yog welded ua ke. Txoj kev no yog tsim los ua cov kab loj loj thiab tuab phab ntsa steel kav.
ASTM A672 C70 Carbon Steel Pipe feem ntau yog siv rau hauv cov roj, roj, dej thiab lwm yam dej hloov pauv, tshwj xeeb tshaj yog qhov yuav tsum tau muab kev pabcuam faus lossis submerged. C70 ncaj seam carbon steel yeeb nkab feem ntau yuav tsum tau kho los tiv thaiv corrosion, xws li txheej los yog cathodic tiv thaiv, kom nws cov kev pab cuam lub neej nyob rau hauv corrosive ib puag ncig.
