Taw qhia rau Shandong Kungang Spiral Yeeb Nkab
The spiral pipe is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a tube blank according to a certain helical angle (called the forming angle), and then welding the pipe seams. Nws tuaj yeem ua nrog lub nqaim strip steel tsim cov taub loj taub loj. Nws cov kev qhia tshwj xeeb yog qhia los ntawm cov uas hla * phab ntsa tuab. Welded yeeb nkab yuav tsum ua kom cov kev kuaj mob hydraulic, lub tensile lub zog ntawm lub weld thiab kev kub txias txias yuav tsum ua raws li cov cai.
Hais txog vuam txheej txheem, kev vuam txoj kev ntawm muab kauv welded yeeb nkab welded yeeb nkab, tab sis qhov tshwm sim ncaj qha welds, yog li qhov tshwm sim ntawm vuam tsis xws luag yog tseem nce, Thiab cov kab hlau vuam ntawm T-puab Welds qhov kev ntxhov siab yog qhov loj me, thiab cov hlau weld feem ntau nyob rau hauv ib qho kev ntxhov siab peb sab, uas nce qhov ua tau ntawm cov kab nrib pleb. Ntxiv mus, raws li cov kev qhia txuj ci ntawm submerged arc vuam, txhua lub ntsej muag pom kev zoo nkauj thiab ib qho ncaj qha welded poin, tab sis tej zaum yuav muaj ntau vuam tsis zoo.
kev siv
Spiral pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. Nws yog ib qho ntawm nees nkaum cov khoom lag luam tseem ceeb tsim los ntawm peb lub tebchaws. Rau cov tsheb thauj mus los: dej so, tso dej, kev kho dej, cov av nkos thauj mus los, dej hiav txwv. Txog kev thauj mus los: roj, chav, roj av roj liquefied. Rau cov hom phiaj txheej txheem: raws li piling kav thiab txuas hniav; Cov kav dej rau cov tsiaj qus, txoj kev, tsev qauv qauv, marine piling kav, thiab lwm yam.
Cov Qauv Khoom
Muab kauv seam tog submerged arc Welded Steel Yeeb Tshuab SY5036-83 rau cov roj tsheb nias txhua lub yog siv rau cov roj thiab nkev pipelines; Muab kauv cov kab kiv cua loj welded steel yeeb nkab sy5038-83 rau cov roj av nias lub lap Muab kauv cov leeg loj ntau zaus Welded Steel Kave rau kev ntaus ntawv ua kua tsheb thauj mus los. Cov yeeb nkab steel muaj lub zog tau coj cov siab muaj txiaj ntsig, zoo plasticity, thiab yooj yim rau vuam thiab kev ua; Tus Kauv Seam Submerged Arc Welded Steel Yeeb Nkab Tsheb Thauj Arc xws li cua thiab chav.
Feem ntau siv cov qauv rau kauv steel kav hlau yog feem ntau muab faib ua cov pipelines, tus qauv GB / T9711.1-1997 (Lub teb chaws tus qauv, kuj Lub npe hu ua Roj thiab Roj Kev Lag Luam Kev Lag Luam Steel) Thawj cov Khoom Siv Hluav Taws Xob (GB / T9711.2 B-American Cov Chaw Tsim Tshuaj Cov yeeb nkab steel; uas tau muab faib ua ob theem: PSL1 thiab PSL1 thiab PSL1 thiab SYSR2), SY5040-92 (kauv subdergle arc welded steel yeeb nkab rau pawg).
