{{0 {}}}} Yog dab tsi txawv ntawm Astm thiab ASME Yeeb Nkab? **
* ** ASTM: ** Feem ntau txhais tau tias yog cov khoom siv tshwj xeeb rau cov khoom siv (zoo li A106, A53) qhia koj * dab tsi cov yeeb nkab yog ua los ntawm * thiab nws cov khoom yooj yim .

* Nyob rau hauv cov ntsiab lus ntawm cov yeeb nkab, "hais txog kev ua raws li cov txheej txheem cuam tshuam nrog cov txheej txheem tshwj xeeb (B31 {{{{5 rau cov nroj tsuag hluav taws xob, B31 {. 3 rau cov nroj tsuag tshuaj) {} nws qhia tau tias cov yeeb nkab tau tsim kho kom nruj kev nyab xeeb cov qauv rau kev taug kev siab. Koj kuj tseem tuaj yeem pom "ASME" cuam tshuam nrog cov ntaub ntawv muaj ntawv pov thawj lossis cov khoom siv tau ntim rau kev siv hauv ASME code tsim.
