ASTM A53 Qib Byog ib qho ntawm cov qauv yeeb nkab hlau uas tau tsim los ntawm American Society for Testing and Materials (ASTM). Cov hauv qab no yog cov lus qhia ntxaws txog A53 Gr.B seamless steel yeeb nkab:
1. Txheej txheem cej luam
ASTM A53 Gr.B cov yeeb nkab hlau tsis muaj qhov txuas. Ntawm cov qauv yeeb nkab hlau uas tau tsim los ntawm American Society for Testing and Materials (ASTM), ASTM A53 muab faib ua ob theem, A thiab B. ASTM sawv cev rau ib pawg qauv Asmeskas. Tus qauv Suav sib xws rau A53A yog GB8163, uas yog ua los ntawm No. 10 hlau, thiab tus qauv Suav sib xws rau A53B yog GB8163, uas yog ua los ntawm No. 20 hlau. Nws feem ntau yog siv rau cov yeeb nkab dav dav.
2. Cov txheej txheem tsim khoom
ASTM A53 Qib Bfeem ntau siv cov thev naus laus zis yeeb nkab seamless hauv cov txheej txheem tsim khoom. Cov thev naus laus zis yeeb nkab seamless yog hais txog cov txheej txheem ntawm kev ua cov billet mus rau hauv cov yeeb nkab hlau nrog cov phab ntsa tuab sib npaug thiab cov nplaim sab hauv thiab sab nraud du los ntawm cov txheej txheem xws li billet perforation, dov, thiab nthuav dav txoj kab uas hla. Txawm hais tias tus qauv ASTM A53 tso cai rau kev siv cov thev naus laus zis yeeb nkab welded los tsim cov yeeb nkab hlau, hauv kev tsim khoom ntawmASTM A53 Qib B, seamless yeeb nkab technology yog lub ntsiab ntau lawm txoj kev.
3. Cov yam ntxwv ntawm cov khoom
Phab ntsa tuab thiab sab nraud precision: Phab ntsa tuab thiab sab nraud ntawm ASTM A53 Gr.B seamless yeeb nkab muaj qhov precision siab thiab tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam qauv nyuaj.
Muaj zog tiv taus siab thiab tiv taus corrosion:ASTM A53 Qib BCov yeeb nkab seamless muaj kev tiv taus siab thiab kev tiv taus corrosion, thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv ntau qhov chaw nyuaj.
Daim ntawv thov dav: ASTM A53 Gr.B seamless yeeb nkab yog tsim rau cov kav dej xa mus rau kev xa roj, kua thiab lwm yam kua dej, suav nrog kev siv hauv kev lag luam, kev muab dej thiab cua sov.
4. Tus qauv ntau yam
ASTM A53 GRB tus qauv siv tau rau cov kav hlau ncaj thiab cov kav hlau carbon uas tsis muaj qhov sib txuas, npog ntau yam txoj kab uas hla sab nraud, phab ntsa tuab thiab cov txheej txheem ua. Raws li cov kev xav tau ntawm daim ntawv thov sib txawv, ASTM A53 GRB cov kav hlau txheem kuj tseem tuaj yeem raug galvanized, kab, txheej, thiab lwm yam kom txhim kho lawv txoj kev tiv thaiv corrosion thiab kev pabcuam lub neej.
