1. Cov yeeb nkab A672 txawv ntawm A106 yeeb nkab li cas?
Teb:Thaum ob qho tib si siv rau siab -kev pabcuam kub, A106 npogseamlesscarbon steel yeeb nkab, whereas A672 npogweldedcarbon steel yeeb nkab. A672 cov kav dej tau txais cov txheej txheem vuam tshwj xeeb thiab kev kho cua sov uas A106 cov kav dej tsis ua.
2. Yuav tsum kuaj dab tsi rau A672 kav?
Teb:Kev xeem yuav tsum muaj xws li:
Hydrostatic Test:Txhua lub yeeb nkab yuav tsum tiv taus lub siab hydrostatic tsis muaj qhov tso tawm.
Kev Ntsuas Siab:Txhawm rau txheeb xyuas cov khoom siv kho tshuab (yield zog, tensile zog).
Flattening Test los yog Khoov Test:Txhawm rau txheeb xyuas qhov ductility thiab soundness ntawm vuam.
Tsis yog-Kev kuaj xyuas kev puas tsuaj:Weld seam yuav tsum yog 100% kuaj los ntawm radiography lossis kuaj ultrasonic.
3. Dab tsi yog tus qauv loj ntawm cov kav dej A672?
Teb:A672 cov kav dej feem ntau muaj nyob rau hauv cov kab uas loj dua, feem ntau ntawm 16 ntiv tes (406 mm) txog 100 ntiv tes (2540 mm) lossis ntau dua, nrog cov phab ntsa tuab haum rau siab - kev pabcuam siab.
4. Cov kav dej A672 puas tuaj yeem siv rau qis-kev pabcuam kub?
Teb:Feem ntau, tsis muaj. A672 yog cov pa roj carbon steel specification, thiab carbon steels tuaj yeem ua nkig ntawm qhov kub thiab txias. Rau qis- kev pabcuam kub, cov ntaub ntawv zoo li ASTM A333, uas tau lees tias muaj kev cuam tshuam hnyav, yog qhov tsim nyog dua.
5. Cov ntaub ntawv dab tsi yog qhov tseem ceeb los qhia meej thaum xaj A672 kav dej?
Teb:Thaum txiav txim, koj yuav tsum qhia:
ASTM Txuj: A672
Qib/Class:(piv txwv li, Chav Kawm C60, Q80) qhia txog lub zog thiab kev kho cua sov.
Loj:Nominal Pipe Size (NPS) thiab lub sij hawm los yog phab ntsa thickness.
Ntev
Hom Ends:(piv txwv li, beveled rau vuam, tiaj kawg).
Txhua yam kev xav tau ntxivlos ntawm tus qauv (piv txwv li, txhim kho kev sim).
