ASTM A106 yog dab tsi?
ASTM A106 1(ASME SA106) yog tus qauv tshwj xeeb rau seamless carbon steel kav rau siab -kev pabcuam kub. Nws muab faib ua peb qib:Qib A, Qib B, thiab Qib C, thiab qhov ua tau zoo ntawm txhua qib nce ntxiv. A106 steel yeeb nkab kuj tsim nyog rau kev ua haujlwm xws li khoov thiab flanging, nrog rau vuam.Nws yog dav siv hauv kev lag luam roj thiab roj, hluav taws xob hluav taws xob, tshuaj lom neeg kev lag luam, kev tsim kho, thiab kev tsim tshuab.
Sau ntawv: ASTM A106 thiab ASME SA 106 cov qauv zoo ib yam hauv cov ntsiab lus. Cov kev cai hauv qab no siv rau ob tus qauv.
Txheej txheem
- Rau lub cevNPE 11/2[DN 40] thiab hauv qab, nws yuav tsum tau tso cai rau muabkub tiav los yog txias kos.
- Tshwj tsis yog txwv tsis pub, yeeb nkabNPS 2 [DN 50] thiab tshajyuav tsum muaj rooj togkub tiav. Thaum pom zoo ntawm cov chaw tsim khoom thiab tus neeg yuav khoom, nws tso cai rau muab cov yeeb nkab txias -kos.
- Txias- kos seamless steel kavmuaj qhov siab dua qhov tseeb thiab qhov siab me me, qhov chaw du, thiab feem ntau siv rau hauv kev tsim khoom, hydraulic systems, thiab lwm yam kev siv uas yuav tsum tau muaj qhov tseeb thiab lub zog.
- Kub Finish Seamless Steel kavyuav muaj oxidized ntawm daim tawv nqaij los yog lwm yam cim ntawm kub ua hauj lwm nyob rau saum npoo thiab yog haum rau daim ntaub ntawv xws li lub tsev, kev thauj mus los, thiab lwm yam. qhov yuav tsum tau rau dimensional precision tsis yog tshwj xeeb yog siab, tab sis lub plasticity ntawm cov khoom yuav tsum tau siab.
Kev kho cua sov
Cov yeeb nkab kub tiav yuav tsum tsis txhob raug kho cua sov. Txias- cov yeeb nkab kos yuav tsum tau kho kom sov tom qab qhov kawg txias kos dhau ntawm qhov kub ntawm 1200℃F (650 degree) lossis siab dua.
