ASTM A179 Cov Qauv Tseem Ceeb
Txog Peb
Txoj kab uas hla
ASTM A179 rau cov hlab nrog sab nraud ntawm 3.2 -76.2 hli [NPS 1/8 - 3 hauv.]
Kev kho cua sov
Thaum tshav kub kub kho ntawm 1200℉ [650 ℃] lossis siab dua tom qab qhov kawg ntawm qhov nqus dej txias.
Qhov tshwm sim
Cov yeeb nkab steel tiav yuav tsum tsis muaj qhov ntsuas.Me ntsis oxidation tsis suav hais tias yog qhov ntsuas.

Flattening Test
Txoj Kev Xeem: ASTM A450 Part 19.
Flaring Test
Txoj Kev Xeem: ASTM A450 Part 21.
Expanded Trivia: Qhov kev sim flaring yog ib qho kev sim siv los ntsuas cov yas deformability thiab tawg tsis kam ntawm cov khoom siv hlau, tshwj xeeb tshaj yog cov raj thaum raug cov txheej txheem flaring.Qhov kev ntsuam xyuas no feem ntau yog siv los ntsuas qhov zoo thiab tsim nyog ntawm cov raj, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau siv vuam, flaring lossis lwm yam kev ua tiav.
Flange Test
Test Method: ASTM A450 Part 22. Alternative to Flare Test.
Expanded Trivia: Feem ntau yog hais txog kev sim siv los ntsuas cov yas deformability thiab tawg tsis kam ntawm cov ntawv hlau, yeeb nkab, lossis lwm yam khoom siv thaum simulated flanged pob qij txha.
Hardness Test
