Seamless square tubes have special regulations for production lines. In terms of data statistics and working environment, an excellent condition can assist people in faster production and manufacturing, improve production efficiency and quality, especially for products such as seamless square tubes that require stable conditions. We should first ensure that the production line focuses on the delicate work of processing technology, machinery and equipment, heating, natural ventilation, drainage pipelines, and other aspects. The core of all work must closely revolve around the quality of seamless square pipes. Just ensure the quality of seamless square pipes, and we can complete all other elements.

无缝方管的造成整个过程是十分的复杂的，它是用碳钢板或者是用热轧带钢替代，接着经历在一定的压力下打卷成型后用电焊的方式使之变为镀锌方钢，接着再经历热镀锌池一番化学反应之后才可以变为现如今现阶段目前市面上我们所可以看到的无缝方管。因而整个过程是错综复杂的，但是只需熟练掌握了这一生产加工生产流程，其使用性能或者比较简单的，加工商局的生产加工率也会进一步提高，其所造成的赢利也是十分丰富的。

The entire process of producing seamless square pipes is very complex. It is replaced by carbon steel plates or hot-rolled strip steel, then subjected to rolling forming under a certain pressure and then welded to become galvanized square steel. Then, after undergoing a chemical reaction in the hot-dip galvanizing pool, it can become the seamless square pipes that we can see on the market at present. Therefore, the entire process is complex, but as long as one proficiently grasps this production and processing process, its performance or relatively simple, the production and processing rate of the processing bureau will also be further improved, and the profits it brings are also very rich.

无缝方管是一种不锈钢板材，毫无疑问净重和其他方钢管有差别，但是我如今都有一些好奇心无缝方管的净重是怎么计算的，因此我专门查了一下无缝方管等方钢管的重量计算公式。大家一起来看一下。

Seamless square tube is a type of stainless steel plate, and there is no doubt that the net weight is different from other square steel pipes. However, I have some curiosity about how to calculate the net weight of seamless square tubes. Therefore, I specifically checked the weight calculation formula for square steel pipes such as seamless square tubes. Let's take a look together.

无缝方管横截面碳钢钢管:每米单位换算:kg/m&lb/ft

Seamless square tube cross section carbon steel pipe: unit conversion per meter: kg/m&lb/ft

常见方钢管计算方法一：(长+宽)×2÷3.14-薄厚×厚度×0.02466=kg/m

Common calculation method for square steel pipes: (length+width) × 2 ÷ 3.14- Thin thickness × thickness × 0.02466=kg/m

公式计算二:kg/m=(Oc-4Wt)*Wt*0.00785

Formula 2: kg/m=(Oc-4Wt) * Wt * 0.00785

无缝方管计算方法

Calculation method for seamless square tubes

方形Oc=4*a

Square Oc=4 * a

长方型Oc=2a+2ba,b是周长

Rectangular Oc=2a+2ba, where b is the circumference

通俗的表述为：4x壁厚x(周长-壁厚)x7.85

The common expression is: 4x wall thickness x (perimeter wall thickness) x 7.85

在其中，方钢管周长和壁厚都以mm为企业，立即把标值带入以上公式计算，得到即是每米方钢管的净重，以克为企业。

Among them, the circumference and wall thickness of the square steel pipe are measured in millimeters, and the standard values are immediately incorporated into the above formula to obtain the net weight of each meter of square steel pipe, measured in grams.

当壁厚和周长都以mm为企业时，4x壁厚x(周长-壁厚)算出的是每米长短方钢管的容积，以立方为企业，再乘于铁的比重每立方7.85克。

When both wall thickness and perimeter are expressed in millimeters, 4x wall thickness x (perimeter wall thickness) calculates the volume of square steel pipes per meter of length, expressed in cubic meters, and multiplied by the specific gravity of iron at 7.85 grams per cubic meter.
