90鋼管理論重量是多少錢

⑴ 90度鋼管重量計算

首先要制算出這個管子的長度
公式：3.14×r÷2=L（長）
計算：3.14×1500÷2=2355（化米為2.355）
其次就可以算這個管子的重量
公式：（管子外徑-管子厚度）×管子厚度×0.02466×管子的長度=重量
計算：(480-10)×10×0.02466×2.355=272.95kg

⑵ 無縫鋼管理論重量表大全及計算方法

對於鋼管相信大家都知道，在房子建造或裝修等中我們都可以見到，除此之外無縫鋼管還有很多其他的用途，今天小編和大家分享的是無縫鋼管理論重量表大全及計算方法：

什麼是無縫鋼管?

無縫鋼管具有中空截面，大量用作輸送流體的管道，如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。鋼管與圓鋼等實心鋼材相比，在抗彎抗扭強度相同時，重量較輕，是一種經濟截面鋼材，廣泛用於製造結構件和機械零件，如石油鑽桿、汽車傳動軸、自行車架以及建築施工中用的鋼腳手架等用鋼管製造環形零件，可提高材料利用率，簡化製造工序，節約材料和加工工時，如滾動軸承套圈、千斤頂套等，已廣泛用鋼管來製造。

無縫鋼管理論重量計算方法:

計算常用型材理論重量計算公式：m=F×L×ρ

m—質量Kg;F—斷面積m2;L—長度m;ρ—密度*Kg/m3

其中：F斷面積計算方法：

1、方鋼F=a2

2、鋼管F=3.1416×$(D-$)D—直徑$—厚度

3、鋼板、扁鋼F=a×$a—寬度

密度：

鋼材：7.85*103kg/m3

鋁：2.5～2.95*103

銅：8.45～8.9*103

鑄鐵：6.6～7*103

尼龍：1.04～1.15*103

⑶ 直徑90壁厚4.5鋼管一米多少錢，每米多重

普通碳鋼、合金鋼鋼管理論重量計算公式為： W=0.02466（D-S）S 注釋：每米重量kg/m=（外徑專-壁厚屬）*壁厚*0.02466 單位取毫米：mm 所以Ф89*4.5的鋼管每米重量為： (89-4.5)*4.5*0.02466=9.377公斤/米。

⑷ 鋼管90mm無縫鋼管,壁厚5mm,一米多少公斤

無縫鋼管的每米重量計算公式-用鋼管的外徑減去壁厚乘以壁厚再乘以0.02466得出來的結果就是每米的重量，
比如:90-5*5*0.02466=每米重量
