Dab tsi yog qhov tshwj xeeb ntawm A672 Cov Yeeb Nkab
Lub ATM A672 tus qauv siv rau cov tub ua los ntawm cov tshuab electrofusion vuam (EFW) cov txheej txheem thiab muaj cov ntsiab lus tseem ceeb hauv qab no:
1. Daim Ntawv Thov Kev Sau Npe
Siv rau nruab nrab thiab tsawg kub (-30 degree ~ {{} {1}}}}}}
2. Cov txheej txheem qib thiab cov txheej txheem
Cov ntaub ntawv raug: Carbon Hlau (piv txwv li C55, C60), Alloy Hlau (piv txwv li C65, C70).
Kev ntsuam xyuas vuam: Qhov zoo ntawm Weld Seam yuav tsum ua kom paub cai los ntawm Radoraplicing Xeem (RT) lossis Ultrasonic kev sim (UT).
Kev Kho Cua Sov: Li Qub (N), Li Qub + Tempering (NT) lossis quenching + txheej txheem raws li cov haujlwm ua haujlwm.
3. Qhov loj thiab siab ntau
Nominal Theaib: Npog DN150 ~ DN1200 (6 ~ 48 ntiv).
Phab Ntsa Thickness: Ntau yam phab ntsa thickness xaiv (piv txwv li Sch40, Sch80), txog 32 MPa.
Lub ntsiab
ASTM A672 hlab yog tsiag ntawv los ntawm cov siab weldability thiab tsawg-kub nyuaj, thiab tau siv dav rau kev tswj hwm cov kua hluav taws xob hauv kev pabcuam hnyav.
