注釋：每米重量kg/m=[（邊長1+邊長2）*2- 壁厚]*壁厚*0.00785 單位取毫米：mm </p> <p> 比如150*200*8的矩形鋼管每米重量為： </p> <p> [(150+200)*2-8]*8*0.00785=43.458公斤/米。 </p> <p> 矩管100X50X5一米重量 </p> <p> 如果你說的200指的是外直徑200毫米，貴陽鍍鋅方矩管生產(chǎn)廠家,5指的是鋼管厚5毫米的話,重量（嚴格說是質(zhì)量）應該如下計算：半徑R＝200/2=100毫米＝10厘米. 內(nèi)部半徑r＝100－5＝95毫米＝9.5厘米. 高h＝1米＝100厘米. 鋼的密度k＝7.9（不同種類鋼的密度會略有不同,差別不是很大）所求重量W＝3.1416X(R的平方－r的平方）XhXk =3.1416X(10的平方－9.5的平方）X100X7.9 ＝3.1416X（100－90.25）X100X7.9 ＝24198克＝24.198千克（或公斤）＝48.396市斤. 若不需要很精確,上面的數(shù)就行了.如果要精確點,你可以查一下你的鋼管那種鋼的密度,重算一下. 比如,你的鋼管是高錳鋼,你可上網(wǎng)查一下高錳鋼的密度.網(wǎng)上說高錳鋼密度大約是7.98,你把上式中的7.9用7，貴陽鍍鋅方矩管生產(chǎn)廠家，貴陽鍍鋅方矩管生產(chǎn)廠家.98換掉重算一下就可以了. </p> <p> <br /> 這家鍍鋅方矩管質(zhì)量高,當天發(fā)貨,合金方矩管,現(xiàn)貨銷售。貴陽鍍鋅方矩管生產(chǎn)廠家</p><div

<p> 2..實彎 </p> <p> 實彎，顧名思義是壓實了彎折，實彎時內(nèi)外輥與管坯內(nèi)外壁雙向壓實。 </p> <p> （1）實彎的優(yōu)點是反彈小，成型準確，而且只要輥型準確，內(nèi)角成型的R比較準確。 </p> <p> （2）實彎的缺點是有拉伸/減薄效應。第1，實彎會使彎折處產(chǎn)生拉伸，拉伸效應使彎折線縱向的長度縮短;第二，實彎彎折處金屬會因拉伸而變薄。貴州熱鍍鋅矩管供應方矩管，熱鍍鋅方矩管，鋼管焊管鍍鋅鋼管可送貨上門，型號齊全!</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
