A53 yeeb nkab Raw Khoom - Carbon Steel Pipe
Cov hlau ua rau ASTM A53 yeeb nkab (ob leeg rau seamless thiab welded) yuav tsum ua raws li cov txheej txheem hauv qab no: qhib lub qhov cub hluav taws xob, lossis cov pa oxygen yooj yim.
Raw steel khoom ntawm qib sib txawv yog nws tus kheej strand cam khwb cia txheeb xyuas ntawm cov khoom hloov pauv tau xav tau. Tus neeg tsim khoom yuav tsum tshem tawm cov ntaub ntawv hloov pauv los ntawm ib qho kev tsim tawm uas tuaj yeem cais cov qib kom meej.
Lub vuam seam rau ERW vuam txheej txheem hauv ASTM A53 Qib B yeeb nkab yuav tsum tau ua tiav kev kho cua sov tom qab vuam mus rau min ntawm 540 degree 1000℉.
Yog li ntawd, tsis muaj qhov tsis muaj martensite seem, lossis siv lwm txoj hauv kev uas tsis muaj martensite seem.
Rau qhov txias txias, qhov nthuav dav yuav tsum tsis pub tshaj 1 1/2% ntawm txoj kab uas hla.
Cov khoom siv rau ASTM A53 Txuj
ib. Seamless Hom S, muaj qib A thiab B.
b. Welded Hom E (ERW), Qib A thiab B.
c. Rauv Welded Hom F, Qib A nkaus xwb.
ASTM A53 yeeb nkab tshuaj muaj pes tsawg leeg thiab txhua yam muaj zog
