GB / T3091 Carbon Steel Pipe Nqe lus piav qhia
GB/T3091 Welded steel yeeb nkab rau qis- cov kua xa tawm yog feem ntau hu ua welded yeeb nkab, feem ntau hu ua cov yeeb nkab dub. Nws yog siv los thauj dej, roj, huab cua, roj thiab cua sov chav, thiab lwm yam dej siab thiab lwm lub hom phiaj ntawm welded steel yeeb nkab. Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov yeeb nkab steel zoo tib yam thiab cov yeeb nkab tuab tuab; daim ntawv ntawm cov yeeb nkab kawg yog muab faib ua cov yeeb nkab steel tsis muaj xov (lub teeb yeeb nkab) thiab steel yeeb nkab nrog threads. Steel yeeb nkab specifications nrog nominal caliber (mm), nominal caliber yog ib qho approximation ntawm lub internal txoj kab uas hla. Customarily siv ntiv tes, xws li 11/2 thiab lwm yam. Welded steel yeeb nkab rau qis- siab thauj cov kua yog siv ncaj qha rau kev thauj cov kua ntxiv nrog rau ntau qhov tsawg- cov dej siab thauj galvanized welded steel kav siv los ua cov yeeb nkab qub.
