kev txiav txim kom ua tau raws li qhov kev thov rau cov kav dej me me, Huayang tau tsim tawm ob txoj kab ntau lawm thaum pib ntawm lub xyoo: 89 kab thiab 127 kab, nrog rau ntau yam ntawm 73MM-127MM. Cov kab ntau lawm tam sim no nyob rau hauv kev ua haujlwm, raws li 89 kab tau ua tiav kev sim ua haujlwm thaum Lub Xya Hli 11, nrog kev ruaj khov vuam zoo thiab du weld seams. Tam sim no Huayang tuaj yeem npog tag nrho ntawm ERW steel yeeb nkab txoj kab uas hla ntawm 73MM-660MM thiab LSAW steel yeeb nkab txoj kab uas hla ntawm 406MM-1422MM. Tsis tas li ntawd, qhov thib ob 273 cov kab ntau lawm yuav muab tso rau hauv kev tsim khoom thaum Lub Kaum Hli, nrog rau phab ntsa tuab txog li 16MM. Cov 377 thiab 351 units uas twb muaj lawm tseem yuav raug kho dua tshiab los tsim cov kav dej welded nrog sab nraud ntawm 355MM thiab 340MM, raws li. Tau ze li ntawm 20 xyoo, Huayang tau cog lus rau nws lub hom phiaj ntawm "kev ua tau zoo hauv kev lag luam", los ntawm ib lub tuam txhab nrog tsuas yog ib qho 325unit ntau lawm kab hauv xyoo 2005 txog tam sim no muaj tag nrho ntawm 16 cov kab ntau lawm.nrog lub peev xwm tsim tau txhua xyoo ntawm 2 lab tons, suav nrog 13 high-frequency welded yeeb nkab ntau lawm kab thiab 3 submerged arc welded yeeb nkab ntau lawm kab. Peb yuav txuas ntxiv mus tob rau hauv kev ua haujlwm ntawm cov kav dej welded thiab siv zog los ua ib lub tuam txhab ua lag luam ntawm longitudinal steel kav nyob rau sab qaum teb Tuam Tshoj.
