1. ASTM A106 yog dab tsi?
ASTM A106 yog tus qauv kev qhia tshwj xeeb rau seamless carbon steel yeeb nkab tsim los rau siab -kev pabcuam kub. Nws yog feem ntau siv rau kev xa cov kua dej, chav, thiab cov pa roj hauv cov chaw tsim hluav taws xob, refineries, thiab boilers.
2. Lub npe "A106" txhais li cas?
"ASTM" yog hais txog lub koom haum qauv, ASTM International. "A" qhia tias nws yog cov khoom siv ferrous. "106" yog tus lej txuas mus rau tus qauv tshwj xeeb rau seamless carbon steel yeeb nkab.
3. Dab tsi yog qhov sib txawv ntawm cov yeeb nkab A106?
ASTM A106 npog peb qib:
Qib A:Lub zog qis, nrog lub zog tensile yam tsawg kawg nkaus ntawm 48,000 psi (330 MPa).
Qib B:Qib feem ntau, nrog lub zog tensile yam tsawg kawg nkaus ntawm 60,000 psi (415 MPa).
Qib C:Lub zog siab dua, nrog lub zog tensile yam tsawg kawg nkaus ntawm 70,000 psi (485 MPa).
4. Puas yog A106 yeeb nkab seamless lossis welded?
ASTM A106 npog tshwj xeebseamlesssteel yeeb nkab, uas yog tsim los ntawm tho ib lub pob zeb uas tsis muaj welds. Qhov no ua rau nws muaj zog thiab txhim khu kev qha rau siab - cov ntawv thov siab.
5. Cov tshuaj lom neeg tseem ceeb ntawm Qib A, B, thiab C yog dab tsi?
Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon, uas nce nrog qib zog.
Qib A: Max Carbon 0.25% (0.21% rau qhov loj dua)
Qib B: Max Carbon 0.30%
Qib C: Max Carbon 0.35%
Cov pa roj carbon ntau dua feem ntau nce lub zog tab sis tuaj yeem txo qis me ntsis weldability.
