LSAW (Straight Seam Welded) steel kav li cas?
LSAW steel kavyog thawj zaug tsim rau hauv cov ntaub ntawv tubular siv cov txheej txheem xws li JCOE lossis UOE, thiab tom qab ntawd welded raws txoj kab ncaj nraim siv ob -sab submerged arc vuam. Cov kauj ruam kawg suav nrog txoj kab uas hla kev nthuav dav los txhim kho qhov tseeb, nrog rau kev tshuaj xyuas zoo xws li kev ntsuas siab thiab ntsuas qhov tsis xws luag.
Dab tsi yog qhov txawv ntawm ASTM A53 Class B LSAW steel kav thiab ERW steel kav?
ASTM A53 Class B LSAW steel kavyog tsim los ntawm steel phaj siv longitudinal submerged arc vuam, thaum ASTM A53 ERW steel kav yog tsim los ntawm steel coils siv kuj welding.
Dab tsi yog cov cuab yeej cuab tam rau ASTM A53 Class B LSAW kav?
ASTM A53 Class B cov kav dejmuaj lub zog siab (lub zog tensile Ntau dua lossis sib npaug ntawm 415 MPa, yield zog Ntau dua lossis sib npaug li 240 MPa). Hais txog kev xaiv cov khoom siv: rau siab lossis thauj khoom- cov kev cai bearing, Class B kav yog nyiam; Yog tias yuav tsum tau khoov txias thiab coiling, Class A kav yog nyiam.
ASTM A53 Class B LSAW yeeb nkab yog dab tsi?
ASTM A53 Class B LSAW steel yeeb nkabmuaj ntau txoj kab uas hla, los ntawm 16 ntiv mus rau 100 ntiv tes, npog loj - txoj kab uas hla steel kav haum rau ntau yam kev siv.
Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov rau ASTM A53 Class B LSAW steel yeeb nkab?
ASTM A53 Class B LSAW steel yeeb nkabFeem ntau yog siv rau kev thauj mus los ntawm cov kua dej (xws li dej, huab cua, thiab qis- siab chav, roj, thiab roj) thiab cov khoom siv, thiab yog siv dav hauv kev lag luam xws li roj thiab roj, petrochemicals, thiab hluav taws xob tsim hluav taws xob.
