LSAW welded yeeb nkab txhais li cas?
LSAW yog lub npe luv raulongitudinal submerged arc welded yeeb nkab. Nws yog tsim los ntawm welding ca steel daim hlau mus rau hauv ib tug tubular zoo, thiab ces welding raws qhov ntev ntawm cov yeeb nkab.
Qhov txawv ntawm ERW welded yeeb nkab thiab LSAW welded yeeb nkab yog dab tsi?
Qhov sib txawv tseem ceeb nyob rau hauv cov txheej txheem vuam: ERW siv siab - zaus kuj vuam los vuam cov npoo ntawm cov hlau kauj, thaumLSAWsiv submerged arc vuam los txuas cov hlau phaj.
Cov ntaub ntawv dab tsi yog A671M LSAW submerged arc welded yeeb nkab ua los ntawm?
ASTM A671M LSAW welded yeeb nkabyog tsim los ntawm longitudinally welding qis - carbon steel daim hlau. Cov ntaub ntawv tshwj xeeb suav nrog qib sib txawv ntawm carbon-raws li alloys. Nws muaj xws li cov khoom xws li carbon, silicon, thiab manganese.
Dab tsi yog qhov txawv ntawm A333 welded yeeb nkab thiab A671 welded yeeb nkab?
A333 welded yeeb nkab haum rau qis- qhov kub thiab txias; thaumA671 welded yeeb nkabyog haum rau chav tsev kub thiab txawm tias qis dua kub. A333 yeeb nkab muaj qhov tsis zoo - kub toughness, thaum A671 yeeb nkab yog tsim los ntawm siab hlab ntsha qib steel daim hlau thiab siv electrofusion vuam.
ASTM A671M LSAW submerged arc welded yeeb nkab yog dab tsi?
Lub zog tawm los ntawmASTM A671M yeeb nkabnyob ntawm qib tshwj xeeb. Piv txwv li, qhov tsawg kawg nkaus tawm lub zog ntawm CC65 qib yog 240 MPa (N / mm²).
