厚(hou)壁(bi)無(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)分(fen)類——熱軋厚(hou)壁(bi)無(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)、冷(leng)軋厚(hou)壁(bi)無(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)、冷(leng)拔(ba)厚(hou)壁(bi)無(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)、擠壓厚(hou)壁(bi)無(wu)縫(feng)(feng)(feng)鋼(gang)管(guan)(guan)、頂管(guan)(guan)

鋼管重量計算(suan)公式:

[(外(wai)徑-壁(bi)厚)*壁(bi)厚]*0.02466=kg/米(每米的重量)

厚壁(bi)無縫管不銹(xiu)鋼(gang)理論重量(liang)計算(suan)公式(shi)：（外徑-壁(bi)厚）×壁(bi)厚×0.02491=KG/M（每米(mi)的(de)重量(liang)）

厚壁無(wu)縫管(guan)合(he)金鋼理論重量計算公(gong)式：（外徑(jing)-壁厚）×壁厚×0.02486=KG/M（每米(mi)的(de)重量）
