ASTM A672 Qib b60 chav kawm 22 EFW Pipe Description
A672GrB60Cl22 yog cov khoom siv qib siab uas ua tau raws li cov qauv thoob ntiaj teb tshwj xeeb. Qhov kev xaiv no muaj cov ntaub ntawv muaj txiaj ntsig: "A672" yog hais txog qhov nruab nrab - qib electrofusion welded steel yeeb nkab qauv, feem ntau yog tsim los ntawm electrofusion vuam, qhov twg steel daim hlau los yog strips yog dov thiab welded ua ke. "GrB60" qhia cov qib tshwj xeeb thiab qhov tsawg kawg nkaus tawm lub zog tus nqi ntawm cov khoom; "Gr" yog ib lo lus luv luv rau "Qib," thiab "B60" qhia qhov tsawg kawg nkaus yield zog nyob rau hauv units. "Cl22" sawv cev rau "Class 22," qhia txog cov yeeb nkab kev kho cua sov. Rau A672GrB60Cl22, nws feem ntau txhais tau hais tias cov yeeb nkab tau muaj kev ntxhov siab- txo qis kev kho cua sov tom qab vuam, uas pab txhim kho nws cov microstructure thiab txhua yam khoom thiab txo qhov seem ntawm vuam kev nyuaj siab.
