How To Calculate The Weight Of SUS347 Stainless Steel Pipes?
Leave a message
When selecting stainless steel pipes, accurately calculating the weight of SUS347 stainless steel pipes is crucial for procurement planning, transportation logistics, and engineering design. This article will explain how to calculate the weight of SUS347 stainless steel pipes based on their dimensions, material, thickness, and length, and will include relevant price lists, standard data, and frequently asked questions from customers.
What is SUS347 stainless steel pipe?
SUS347 stainless steel pipes is austenitic stainless steel pipes stabilized with niobium (Nb) to prevent carbide precipitation, containing 17–19 % Cr, 9–13 % Ni, and 0.7–1.0 % Nb, offering excellent high‑temperature strength and intergranular corrosion resistance in the 427–816 °C range, with minimum tensile strength 515 MPa, yield strength 205 MPa, and elongation 35 % (per ASTM A312/JIS G3459), making them ideal for boiler, superheater, and heat exchanger applications in petrochemical and power plants.
How to Calculate the Weight of SUS347 Stainless Steel Pipes
Weight Calculation Formula for Pipes
Do: Outer diameter (mm)
Di: Inner diameter (mm)
Length: Length (m)
Density: Density of stainless steel; the density of SUS347 is typically 8.0 g/cm³ or 8000 kg/m³
Example Calculation
Assume you have a SUS347 stainless steel pipe with an outer diameter of 50mm, an inner diameter of 40mm, and a length of 6m. According to the formula:
The approximate weight of this pipe is 39.3 kg.
