** 1. Dab tsi yog ASTM A106 yeeb nkab? **
ASTM A106 yog ib qho tshwj xeeb rau cov khoom siv hlau Seamless steel tsim rau kev pab kub kub. Nws yog feem ntau siv nyob rau hauv cov nroj tsuag hluav taws xob, ua kom zoo dua, thiab kev lag luam rau cov kua dej thiab roj av ntawm cov ntsuas kub thiab ntsuas. Tus qauv siv peb qib (A, B, thiab C), nrog qib B ua qhov feem ntau siv tau vim nws qhov sib npaug ntawm lub zog thiab ua haujlwm.
** 2. Dab tsi yog ASTM A106 sib npaug rau? **
ASTM A106 yog qhov sib npaug dav dav rau cov qauv thoob ntiaj teb xws li:
- ** PY {10216-1 (p235Gh, P265GHGh) ** hauv Tebchaws Europe.
- ** JIS G3454 (STS410 \/ STS480) ** hauv Nyij Pooj.
- ** DIN 17175 (ST35.8 \/ ST45.8) ** Hauv Tebchaws Yelemees.
Nco ntsoov tias kev sib txig sib luag yog nyob ntawm cov qhab nia tshwj xeeb thiab cov ntawv thov yuav tsum tau ua.
** 3. Qhov twg yog qhov zoo dua, ASTM A106 B lossis ASTM A53 B? **
Kev xaiv yog nyob ntawm daim ntawv thov:
- ** SHTM A106 B ** yog tsim rau ** kev pab kub-(txog li 750 degree F \/ 400 degree) thiab muaj cov ntaub ntawv zoo dua (piv txwv li ntau dua cov ntsiab lus carbon).
- ** ASTM A53 B ** yog npaj rau ** Tsawg \/ Kub-Kub ** Cov Ntawv Thov (piv txwv, cov khoom siv siv) thiab muaj txiaj ntsig ntau dua.
Rau kev kub siab lossis cov tshuab siab siab (piv txwv li cov kab hauv qab), A106 B yog zoo dua. Rau kev siv dav dav-hom phiaj, A53 B tuaj yeem txaus.
** 4. Dab tsi yog qhov sib txawv ntawm qib kawm thiab qib b hauv A106? **
- ** QIB QIB B muaj ib nyuag qib carbon monoxide ({{{{}}}}}}}}.}.} {}}
- ** COV NEEG KHO PIB HEEV **: Qib B muaj lub zog siab dua (430 MPA Min vs. 330 MPa rau qib A) thiab tawm lub zog (240 MPA Min vs. 205 MPA rau qib A).
Qib B muaj zog dua thiab tsim nyog rau cov ntawv thov xav tau, thaum qib kawm yog siv rau kev ua haujlwm sib tw.
** 5. Dab tsi yog i106b yeeb nkab? **
ASTM A106 Qib B (A106B) yog qib tshwj xeeb hauv Astm A106 tus qauv. Nws yog ib tug neeg siv roj ntsha seamless cov yeeb nkab nrog txhim kho lub zog thiab qhov kub siv tau ntau, cov tshuab hluav taws xob siab xws li cov nroj tsuag hluav taws xob, cov nroj tsuag tsiaj, thiab cov khoom siv hluav taws xob. Nws cov tshuaj thiab cov khoom siv tshuab ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev siv lub sijhawm thaum cua sov.
