First, the formula for calculating the weight of stainless steel seamless pipe.
A stainless steel seamless pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils. The theoretical weight calculation formula of stainless steel seamless pipe: weight (kg) = (outer diameter-actual thickness) * actual thickness * 0.02491 * length. For example: the theoretical weight of a single 6-meter-long stainless steel seamless pipe with a solid thickness of 3.5mm and an outer diameter of 57mm is: (57-*3.5) * 3.5 * 0.02491 * 6 = 5.41kg.
The principle of this formula is to calculate the weight based on the cross-sectional area and density of the pipe. The cross-sectional area is (outer diameter-wall thickness) × wall thickness, in square millimeters. Multiply by the length in cubic millimeters. Since the unit of density is usually grams/cubic centimeter, the result needs to be divided by 1,000,000 to get the volume in cubic meters. Finally, multiply by 0.02466, which is the coefficient for converting the unit of weight from grams to kilograms.
It should be noted that seamless pipes of different materials have different densities, so when calculating the weight, you need to know the specific material of the pipe. At the same time, the units in the formula should be adjusted according to the actual situation, such as length and outer diameter may use units such as inches or centimeters.

Second, what is the impact of the weight of stainless steel seamless pipe on its use?
The weight per meter of stainless steel seamless pipe is one of its important physical parameters and has a certain impact on its use. When making equipment, it is necessary to determine the specifications and weight of the pipe according to actual use needs to meet the bearing capacity and stability requirements of the equipment. In addition, stainless steel seamless pipes of different specifications have different weights per meter, and choosing the right specifications can improve the service life and economic benefits of the facility.

Third, factors affecting the weight of stainless steel seamless pipes
In addition to the diameter and wall thickness of the pipe, many factors affect the weight of stainless steel seamless pipes.
1. The first is the density of the material. Different types of stainless steel have different densities, so the weight of stainless steel seamless pipes with the same outer diameter and wall thickness is also different.
2. The second is the influence of surface treatment. The surface treatment of stainless steel seamless pipes will also affect their weight. For example, painting, galvanizing, and other treatments will increase the weight of the pipe.
3. Finally, the influence of length. Stainless steel seamless pipes with the same diameter and wall thickness have different lengths and different weights.
