Astm a53 seamless yeeb nkabyog tsim los ntawm cov kav dej carbon thiab hlau, cov yam ntxwv tsis muaj qhov sib txuas ua rau nws muaj lub zog siab thiab tiv taus corrosion, siv dav hauv roj av, kev lag luam tshuaj lom neeg, tshuab, aviation, aerospace thiab lwm yam teb. Nws cov yam ntxwv tseem ceeb suav nrog cov hauv qab no:
1. Lub zog siab: Vim yog cov txheej txheem tsim khoom thiab cov yam ntxwv ntawm cov yeeb nkab hlau tsis sib xws, cov yeeb nkab hlau tsis sib xws muaj lub zog tensile siab thiab lub zog tawm los.
2. Muaj zog tiv thaiv corrosion: carbon hlaucov yeeb nkab hlau tsis muaj seamlessmuaj kev tiv thaiv corrosion zoo, rau qee cov kua qaub muaj zog, alkali muaj zog thiab lwm yam tshuaj lom neeg uas muaj kev tiv thaiv zoo.
3. Cov txheej txheem tsim khoom yooj yim: cov txheej txheem tsim cov yeeb nkab hlau tsis muaj hlau yog qhov yooj yim, pheej yig, ua haujlwm tau zoo.
4. Siv dav: cov yeeb nkab hlau carbon seamless yog siv dav hauv roj av, kev lag luam tshuaj lom neeg, tshuab, aviation, aerospace thiab lwm yam teb, yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm cov kav dej.
