**1. Puas yog A106 yeeb nkab seamless lossis welded?
ASTM A106 yeeb nkab yog qhov tshwj xeeb rau seamless carbon steel yeeb nkab. Nws yog tsim los tsis muaj seam weld thiab yog npaj rau siab -kev pab kub. Tus qauv tsis npog welded yeeb nkab.
**2. Qhov kub siab tshaj plaws rau A106 yog dab tsi?**
Qhov siab tshaj plaws kev pabcuam kub rau ASTM A106 yeeb nkab yog 1000℃F (538 degree). Rau qhov kub thiab txias ntawm 1000℃F thiab 1100℃F (538℃txog 593 degree), qhov siab tshaj plaws uas tso cai rau kev ntxhov siab yog txo qis. Nws tsis pom zoo kom siv siab tshaj 1100℃F.
**3. ASTM tus qauv rau carbon steel yeeb nkab yog dab tsi?
Muaj ntau cov qauv ASTM tseem ceeb rau cov pa roj carbon steel yeeb nkab, txhua qhov kev pabcuam sib txawv. Cov feem ntau muaj xws li:
* ** ASTM A106:** Rau seamless carbon steel yeeb nkab rau siab -kev pab kub.
* ** ASTM A53:** Rau ob qho tib si seamless thiab welded (ERW) carbon steel yeeb nkab, feem ntau rau kev dav dav thiab qis - qhov kev pab kub.
* ** ASTM A333:** Rau seamless thiab welded steel yeeb nkab rau qis - kub kev pab cuam.
* ** ASTM A135:** Rau hluav taws xob -tsis kam welded (ERW) steel yeeb nkab.
** 4. Qhov txawv ntawm Qib A thiab Qib B A106 yog dab tsi?**
Qhov sib txawv tseem ceeb ntawm Qib A thiab Qib B ntawm A106 yog nyob rau hauv lawv cov khoom siv kho tshuab, feem ntau tensile lub zog thiab lub zog tawm los.
* ** Qib A ** muaj lub zog tensile yam tsawg kawg nkaus ntawm 48,000 psi thiab qhov tsawg kawg nkaus yield zog ntawm 30,000 psi.
* ** Qib B ** muaj lub zog tensile tsawg dua ntawm 60,000 psi thiab siab dua qhov ua tau zoo ntawm 35,000 psi.
Vim nws lub zog ntau dua, ** Qib B yog qhov feem ntau siv thiab teev qib ** rau siab - muaj cov ntawv thov. Kuj tseem muaj qhov sib txawv me me ntawm cov tshuaj muaj pes tsawg leeg, nrog Qib B tso cai me ntsis carbon thiab manganese cov ntsiab lus kom ua tiav nws lub zog ntau dua.
**5. ASTM C 612 yog dab tsi?
ASTM C612 yog tus qauv specification rau "Mineral Fiber Block thiab Board Thermal rwb thaiv tsev." Nws npog nonstructural, nruj rwb thaiv tsev boards thiab blocks ua los ntawm cov ntxhia fibers (feem ntau yog pob zeb, slag, los yog iav) sib txuas nrog lub tshav kub -resistant binder. Qhov rwb thaiv tsev no yog siv rau cov ntawv thov ntawm qhov chaw ua haujlwm ntawm qhov kub ntawm 80℃F thiab 1200℃F (27℃txog 649 degree), xws li cov khoom siv hauv tsev, boilers, thiab ducts.
