【镀锌管国标】尺寸规格表都是根据理论重量计算公式算出来的,一般有圆管的和方管两种。圆管的里算方法简单点,方管的相对复杂一些。下面给大家介绍几种镀锌管的尺寸规格如下:



【镀锌管国标】尺寸规格表方矩形钢管理论重量计算公式:


  正方形和长方形(矩形)截面碳钢钢管:每米重量单位: kg/m(千克/米) & lb/ft(磅/英尺)

  常用方矩管计算公式为: (长+宽)×2÷3.14-厚度×厚度×0.02466= kg/m

  公式二:kg/m = (Oc - 4Wt) * Wt * 0.00785

  其中:Oc是钢管外周长,Wt是钢管壁厚; 正方形Oc=4*a ; 长方形Oc=2a+2b a,b是边长 通俗的解释为:4x壁厚x(边长-壁厚)x7.85

  其中,方管边长和壁厚都以毫米为单位,直接把数值代入上述公式,得出即为每米方管的重量,以克为单位。


我国水管的规格均采用我国法定单位的公称直径来标称的。如DN20,就是表示公称直径20毫米的镀锌水管。镀锌水管的系列有:DN15、DN20、DN25、DN32、DN4O、DN50、DN65、DN80、DN100、......等。


镀锌管国标】尺寸规格表金属管: 

镀锌管、不锈钢管、不锈钢衬塑管、薄壁不锈钢管、镀锌衬塑管、铜管、铸铁管等。

如果分母和分子能够约分,如分子是2、4、8、16、32时如果能够约分,就应该约分。 

英寸的表示是在右上角打上两撇,如1/2" 

如DN25的水管就是英制1"的水管,也是解放前的8分水管。 

DN15的水管就是英制1/2"的水管,也是解放前的4分水管。 

如DN20的水管就是英制3/4"的水管,也是解放前的6分水管。


英寸的表示是在右上角打上两撇,如1/2" 

如DN25(25mm,下同)的水管就是英制1"的水管,也是解放前的8分水管。 

DN15的水管就是英制1/2"的水管,也是解放前的4分水管。 

如DN20的水管就是英制3/4"的水管,也是解放前的6分水管。 


材质: 材质就有很多,根据不同的需要。

标准: 有英制标准和国际标准两种。 

尺寸: 

DN15(4分管)、DN20(6分管)、DN25(1寸管)、DN32(1寸2管)、DN40(1寸半管)、DN50(2寸管)、DN65(2寸半管)、DN80(3寸管)、DN100(4寸管)、DN125(5寸管)、DN150(6寸管)、DN200(8寸管)、DN250(10寸管)等。 


以上这些都是【镀锌管国标】尺寸规格表,对应您的设计图纸找自己所需规格,壁厚一般都是国标,http://www.niutoug.com,销售电话13820022223

Intel has had partners that would like Intel to design accelerators around their technology, but lacked the resources, Waxman said. The new spirit of collaboration benefits both sides.

This work, and others like it, could herald new understanding of Schrödinger cat states, and allow the development of sophisticated quantum computers.
