ASTM A672 LSAW steel yeeb nkab yog dab tsi?
ASTM A672 LSAW steel yeeb nkabyog ib hom steel yeeb nkab ua los ntawm siab hlab ntsha qib steel phaj siv electrofusion vuam (EFW). "LSAW" (longitudinal submerged arc vuam) qhia tias cov yeeb nkab steel yog welded raws nws qhov ntev, pib los ntawm cov hlau phaj.
Dab tsi yog qhov txawv ntawm DSAW thiab LSAW steel yeeb nkab?
Qhov sib txawv tseem ceeb yog DSAW (ob chav -sided submerged arc vuam) steel yeeb nkab muaj welds ntawm ob sab hauv thiab sab nraud, thaumLSAW (longitudinal submerged arc vuam) steel yeeb nkabyog welded tsuas yog nyob rau sab nraud.
Qhov txawv ntawm ERW thiab LSAW steel yeeb nkab yog dab tsi?
Qhov sib txawv tseem ceeb nyob hauv cov txheej txheem tsim khoom thiab cov khoom kawg ntawm cov yeeb nkab steel: ERW steel yeeb nkab yog tsim los ntawm cov coils thiab welded siv high - zaus tam sim no; thaumLSAW steel yeeb nkabyog tsim los ntawm steel phaj thiab welded longitudinally siv submerged arc vuam.
