(1) seamless steel yeeb nkab feem ntau yog dov los ntawm cov hlau los yog cov hlau tsis tshua muaj hlau, yog qhov kev thov ntawm cov yeeb nkab steel, nws qhov chaw hla ntu loj dua, chav tsev nyob hauv siab yog me dua.
(2) Seamed steel kav yog siv los thauj cov kua dej.Vim tias qhov kev tsim khoom tuaj yeem raug welded, yog li qhov kev sib koom ua ke yuav tsum muaj zog siab, thiab kom ntseeg tau tias qhov sib koom ua ke muaj kev tiv thaiv corrosion thiab kub tsis kam, thiab lwm yam.
(3) Seamless steel yeeb nkab yog siv dav hauv kev tsim khoom, roj av, tshuaj lom neeg, hluav taws xob, kev tsim kho thiab lwm yam lag luam, siv ntau dua.
(4) los ntawm cov txheej txheem tsim khoom, kev tsim cov txheej txheem ntawm seamless steel yeeb nkab yog ntau dua, seamed steel yeeb nkab siv cov txheej txheem yooj yim.
(5) Los ntawm qhov kev xav ntawm kev siv, qhov sib txawv ntawm ob yog tsis ntau, tab sis lub qub yog siv los thauj cov kua thiab qee cov khoom, qhov tom kawg yog siv los thauj cov kua.
(6) Los ntawm cov khoom siv, tsis muaj qhov sib txawv tseem ceeb ntawm ob, feem ntau vim tias cov yeeb nkab seamless steel siv rau hauv cov khoom muaj ntau yam khoom siv hlau thiab ua rau qee qhov sib txawv ntawm tus nqi.
(7) Los ntawm qhov kev xav ntawm kev siv, cov qub feem ntau yog siv rau hauv cov khoom thauj khoom ntawm lub tsev thiab cov tsheb ciav hlau txoj kev loj choj thiab lwm qhov chaw;tom kawg yog feem ntau siv hauv roj av, tshuaj lom neeg, hluav taws xob fais fab, tshuab tsim thiab lwm yam lag luam.
(8) Los ntawm qhov pom ntawm tus nqi, qhov qub yog qhov zoo tshaj qhov tom kawg ntawm qhov zoo thiab tus nqi.Qhov sib txawv ntawm seamless steel yeeb nkab thiab seamed steel yeeb nkab tuaj yeem pom los ntawm cov lus qhia saum toj no: seamless steel yeeb nkab yog siv los thauj cov kua dej;thiab seamed steel yeeb nkab yog siv los thauj cov kua, khib nyiab, thiab lwm yam.
Tab sis nyob rau hauv tib txoj kev siv seamless steel yeeb nkab tuaj yeem thauj cov dej loj dua thiab qee cov khoom siv, thiab rau cov kav dej seamless steel yeeb nkab yog corrosion-resistant ntau dua seamed steel yeeb nkab, lub neej ntev kev pab cuam;
