ASTM B622 Hastelloy Pipe Loj thiab kam rau ua
ASTM B 622 2teev cov lus loj (Tej Sij Hawm Sij Hawm) ntawm cov kav dej seamless hauv cov ntawv ntxiv. Lub rooj loj no yog xaiv tau. Hais tias, lwm qhov ntev tshaj li lub rooj kuj tau txais. Qhov tseeb, lub rooj loj no yog ib feem ntawm ASME B36.10. Hauv kev siv tswv yim, qhov loj ntawm cov yeeb nkab seamless tuaj yeem raug kho raws liASME B36.10thiabASME B36.19. Lwm yam uas tsis yog - qhov loj me kuj tuaj yeem ua tau.
Tsis tas li ntawd, qhov ntev ntev ntawm cov khoom siv tsis ncaj qha rau hauv tus qauv. Txawm li cas los xij,ASTM B829 Cov khoom lag luamyog hais nyob rau hauv tus qauv. Qhov no txhais tau hais tias hauv kev tsim khoom tiag tiag, cov tuam txhab tsim khoom yuav tsum ua raws li qhov yuav tsum tau ua ntawm ASTM B829.

Kev Ntsuas & Dimensional Quality Control Raws li ASTM B622
Txhawm rau txheeb xyuas tias txhua pawg ntawm Hastelloy seamless yeeb nkab ua tau raws li ob qho tib si cov txheej txheem thiab cov kev txwv lub cev tsis muaj zog, cov khoom siv yuav tsum tau kuaj xyuas qhov zoo:
Kev Ntsuas Hydrostatic:Txhua ntu yeeb nkab yuav tsum tau kuaj nrog hydrostatic kuaj xyuas cov phab ntsa kev ncaj ncees nyob rau hauv cov txheej txheem siab yam tsis muaj to.
Nondestructive Electric Test:Ultrasonic lossis eddy-cov kev xaiv kev sim tam sim no tuaj yeem siv tau raws li tus neeg yuav khoom qhov tshwj xeeb txhawm rau txheeb xyuas cov subsurface micro- tawg.
Visual thiab Geometric Verification:Calibrated micrometers thiab laser nrhiav cov cuab yeej lav kev ua raws li OD thiab phab ntsa thickness txwv tau sau tseg saum toj no.
