1. Q: Dab tsi yog qhov feem ntau ASTM specification rau seamless carbon steel yeeb nkab rau siab - kub kev pab cuam?
A: ASTM A106 Gr. B. Nws npog seamless carbon steel yeeb nkab rau siab - kev pabcuam kub nrog lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa (60,200 psi) thiab siv dav hauv cov chaw tsim hluav taws xob thiab cov chaw tsim khoom.
2. Q: Dab tsi txawv ASTM A53 los ntawm ASTM A106?
A: A53 npog ob qho tib si welded (Hom E, F) thiab seamless (Type S) yeeb nkab rau kev siv dav dav, thaum A106 tshwj xeeb rau seamless yeeb nkab npaj rau siab - kev pabcuam kub. A106 muaj kev nruj dua tshuaj lom neeg thiab kev siv tshuab.
3. Q: Cov qib carbon steel twg yog tus qauv rau seamless siab tubing hauv boilers?
A: ASTM A192 Cov Lus Qhia Qib no yog tshwj xeeb rau seamless carbon steel boiler raj rau siab - kev pabcuam siab, paub txog nws txoj kev ntseeg siab hauv kev siv boiler saturated.
4. Q: Dab tsi yog qhov tseem ceeb ntawm API 5L seamless kab yeeb nkab?
A: Nws yog siv rau kev xa roj, dej, thiab roj hauv kev lag luam roj av thiab roj av, ob qho tib si onshore thiab offshore. Qib zoo li X42, X52, X65 qhia qhov tsawg kawg nkaus lub zog.
5. Q: Lub ntsiab tseem ceeb twg txawv ntawm AISI / SAE 1020 los ntawm 1045 steel hauv cov yeeb nkab ua?
A: Cov ntsiab lus carbon . 1020 yog qis- carbon steel (~ 0.20% C) nrog zoo weldability thiab formability, thaum 1045 yog ib tug nruab nrab - carbon steel (~ 0.45% C) nrog ntau zog thiab hardness tab sis qis weldability.
