Kauv raj thiab nws cov qauv kev faib tawm:
Kev siv cov kua dej siab siv cov pob qij txha faus arc vuam steel kav (SY5036-83) feem ntau yog siv los thauj cov roj thiab cov kav dej ntuj; rau underwritten fluid kev thauj mus los, high-frequency welding steel yeeb nkab (SY5038-83), high-frequency kev twb kev txuas vuam txoj kev yog siv Welded thiab siv rau cov kauv seam high-frequency vuam steel yeeb nkab rau siab thauj. Cov yeeb nkab steel muaj lub zog siab thiab zoo plasticity, uas yooj yim rau vuam thiab ua. Feem ntau, low-voltage fluid conveyor siv cov kauv sib koom ua ke faus arc vuam steel yeeb nkab (SY5037-83). Gas, huab cua, thiab chav dav dav low-voltage fluid conveyor faus arc vuam steel kav.
Cov qauv ntawm cov kav raj feem ntau muab faib ua: SY/T5037-2000 (cov qauv tseem ceeb, tseem hu ua cov kua dej zoo tib yam conveying kav rau faus arc welded steel kav), GB / T9711.1-1997 (national standard , tseem hu ua roj thiab roj kev lag luam kev thauj mus los Thawj feem ntawm cov txheej txheem ntawm cov yeeb nkab steel xa tuaj: Chav A (Class A (GB / T9711.2 B-Class steel yeeb nkab) yuav tsum nruj), API{{ 6}}L (American Petroleum Association, tseem hu ua pipeline steel yeeb nkab; suav nrog PSL1 thiab PSL2 ob Theem), SY/T5040-92 (pile nrog kauv pob qij txha faus arc vuam steel kav).
Kauv raj khoom: Q235A, Q23B, 0CR13, 1CR17, 00CR19NI11, 1CR18NI9, 0CR18NI11nb. Q345 L245 X46 X70 X80 X95
Lub kauv steel yeeb nkab muaj ntau yam kev siv, haum rau kev lag luam roj thiab ntuj, kev tsim kho, choj thiab qhov av engineering, thiab kev ua liaj ua teb thiab nuv ntses. Nws lub zog siab, kev tiv thaiv corrosion thiab kev ua tau zoo sealing ua rau nws yog ib qho ntawm cov khoom tseem ceeb hauv txhua qhov chaw ntawm lub neej.
