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.
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.
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.
Seamless square tube cross section carbon steel pipe: unit conversion per meter: kg/m&lb/ft
Common calculation method for square steel pipes: (length+width) × 2 ÷ 3.14- Thin thickness × thickness × 0.02466=kg/m
Formula 2: kg/m=(Oc-4Wt) * Wt * 0.00785
Calculation method for seamless square tubes
Square Oc=4 * a
Rectangular Oc=2a+2ba, where b is the circumference
The common expression is: 4x wall thickness x (perimeter wall thickness) x 7.85
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.
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.
