ASTM A269 Tib Presyon Rating
Evalyasyon presyon an pouTib asye pur ASTM A269depann sou plizyè faktè tankou materyèl la, dimansyon, ak tanperati. ASTM A269 se yon spesifikasyon estanda pou san pwoblèm ak soude tib asye pur austenitic pou sèvis jeneral. Evalyasyon presyon an anjeneral detèmine ki baze sou kritè konsepsyon, pwopriyete materyèl, ak estanda fabrikasyon.
Faktè kle ki enfliyanse evalyasyon presyon an enkli:
1. Klas materyèl: ASTM A269 kouvri plizyè klas austenitic en fe, tankouASTM A269 TP304, 304L, 316, ak 316L. Diferan klas yo gen diferan evalyasyon presyon akòz varyasyon nan pwopriyete mekanik yo.
2. Dimansyon: laASTM A269 tibDyamèt ekstèn, epesè miray la, ak longè jwe yon wòl enpòtan nan detèmine evalyasyon presyon li yo. Pi epè miray ak pi piti dyamèt jeneralman rezilta nan pi wo evalyasyon presyon.
3. Tanperati: Tanperati ki wo ka afekte pwopriyete materyèl asye pur. Evalyasyon presyon ka diminye nan tanperati ki pi wo, e enfòmasyon sa a anjeneral konsidere nan kalkil konsepsyon yo.
