ASTM A53 Cov Yeeb Nkab Txheem: Cov Lus Qhia Siv Dav Dav ASTM A53 cov yeeb nkab hlau yog ib qho ntawm cov qauv siv dav tshaj plaws rau cov yeeb nkab hlau hauv ntiaj teb hauv kev lag luam ntawm cov kav dej thiab kev tsim kho. Muaj peb hom: LSAW, SSAW, thiab ERW, tab sis lawv cov txheej txheem tsim khoom sib txawv thiab daim ntawv thov kuj sib txawv.
1. ASTM A53 LSAW Cov Yeeb Nkab Hlau(Kev Vuam Ntev Submerged Arc)
Cov Yeeb Nkab LSAW yog tsim los ntawm kev khoov cov hlau phaj ntev ces welded thiab cov seam welded nyob rau sab hauv thiab sab nraud ntawm cov yeeb nkab! Cov yeeb nkab LSAW, muaj cov hlau zoo, zoo tagnrho rau kev siv roj thiab roj siab. Cov welds muaj zog thiab phab ntsa tuab ua rau cov yeeb nkab no haum rau cov yeeb nkab roj thiab roj siab, kev siv dej hiav txwv.
2. ASTM A53SSAWCov Yeeb Nkab Hlau(Kauv Submerged Arc Welded)
Cov Yeeb Nkab Uas Muaj Kauv Sib Nraus (SSAW) yog ua los ntawm kev siv txoj kev sib txuas uas muaj kauv sib nraus. Lawv cov kauv sib nraus ua rau muaj kev tsim khoom pheej yig thiab ua rau lawv zoo tagnrho rau cov kav dej loj uas muaj qhov siab nruab nrab mus rau qis lossis rau kev siv rau hauv cov qauv.
3.ASTM A53ERWCov Yeeb Nkab Hlau(Hluav Taws Xob Tiv Thaiv Welded)
Cov kav dej ERW yog ua los ntawm kev vuam hluav taws xob tsis kam, yog li ntawd qhov me me ntawm qhov nkhaus yog qhov xav tau rau kev khoov hauv kev npaj vuam uas tso cai rau kev tsim cov kav dej nrog txoj kab uas hla me me nrog cov vuam meej, tus nqi tsim khoom rau cov kav dej zoo li no tsawg heev. Lawv feem ntau siv rau hauv kev tsim kho rau cov thav duab, cov kav dej kho tshuab, thiab kev thauj cov kua ntawm qhov siab qis.
Cov hauv qab no yog qhov sib txawv tseem ceeb:
Txheej Txheem VuamCov txheej txheem LSAW/SSAW muaj xws li kev vuam submerged arc, ERW yog cov txheej txheem vuam hluav taws xob tsis kam.
Txoj kab uas hla & Phab ntsa tuabCov kav dej LSAW muaj cov kab uas hla loj dua nrog cov phab ntsa tuab dua piv rau cov kav dej SSAW thiab ERW.
