316l stainless steel pipe weight calculation formula is what?
Stainless steel pipe model specifications are different, different regions, different wall thickness then the price is not the same. The first premise we need to determine is: What is the specification of the steel pipe in question? For example, the commonly used steel pipe specifications are: 108*4.5, 219*6, 377*10, etc., the outer diameter and wall thickness specifications are different, the weight of the steel pipe is different, so the price of the steel pipe per meter is also different. The theoretical weight calculation formula of ordinary carbon steel pipe is: kg/m per meter weight = (outer diameter mm- wall thickness mm) * wall thickness mm*0.02466. For example, the weight of 108*4.5 per meter of stock 20# steel pipe is: kg/m= (108-4.5) *4.5*0.02466=11.485 According to the 108*4.5 steel pipe market price of 4500 yuan/ton, we can know that 108*4.5 steel pipe per meter price is: 11.485*4.5=51.68 yuan.
