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.

無縫方管的造成整個過程是十分的復雜的，它是用碳鋼板或者是用熱軋帶鋼替代，接著經歷在一定的壓力下打卷成型后用電焊的方式使之變為鍍鋅方鋼，接著再經歷熱鍍鋅池一番化學反應之后才可以變為現如今現階段目前市面上我們所可以看到的無縫方管。因而整個過程是錯綜復雜的，但是只需熟練掌握了這一生產加工生產流程，其使用性能或者比較簡單的，加工商局的生產加工率也會進一步提高，其所造成的贏利也是十分豐富的。

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.

無縫方管是一種不銹鋼板材，毫無疑問凈重和其他方鋼管有差別，但是我如今都有一些好奇心無縫方管的凈重是怎么計算的，因此我專門查了一下無縫方管等方鋼管的重量計算公式。大家一起來看一下。

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.

無縫方管橫截面碳鋼鋼管:每米單位換算:kg/m&lb/ft

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

常見方鋼管計算方法一：(長+寬)×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

公式計算二:kg/m=(Oc-4Wt)*Wt*0.00785

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

無縫方管計算方法

Calculation method for seamless square tubes

方形Oc=4*a

Square Oc=4 * a

長方型Oc=2a+2ba,b是周長

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

通俗的表述為：4x壁厚x(周長-壁厚)x7.85

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

在其中，方鋼管周長和壁厚都以mm為企業，立即把標值帶入以上公式計算，得到即是每米方鋼管的凈重，以克為企業。

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.

當壁厚和周長都以mm為企業時，4x壁厚x(周長-壁厚)算出的是每米長短方鋼管的容積，以立方為企業，再乘于鐵的比重每立方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.
