Calculating the weight of pipes is an essential step in performing stress analysis, ensuring safety and efficiency in pipeline design and operation. An engineer typically needs to determine the pipe weight in kg/m or lb/ft under the following conditions:

1. Empty Condition – Weight of the pipe when it is not carrying any fluid.
2. Operating Condition – Weight of the pipe when operating and carrying its regular product.
3. Hydrotest Condition – Weight of the pipe when filled with water for hydrostatic testing.

The below calculator is designed to calculate the pipe weight in kg/m or lb/ft for these conditions. It supports three types of pipe materials commonly used in the industry:

• Carbon Steel (CS) Pipe: 7850 kg/m³
• Mild Steel (MS) Pipe: 7860 kg/m³
• Stainless Steel (SS) Pipe: 8000 kg/m³

Key Features:

• Pipe Self Weight: This represents the weight of the pipe material itself.
• Insulation Weight: If the pipe is insulated, the weight of the insulation material will be included in the calculation.
• Product Weight: This is the weight of the product (fluid or gas) that the pipe is designed to carry.
• Water Weight: For hydro test conditions, this calculates the weight of water used to test the pipeline’s strength.
• For All Three Conditions: The calculator provides Empty, Operating, and Hydrotest results in both kg/m and lb/ft.

Additional Features:

• Unit Conversion: Users can input the inside and outside diameters of the pipe in mm or inches, and the calculator will handle the necessary unit conversions.
• Material Selection: Choose between Carbon, Mild, or Stainless Steel for accurate density-based calculations.
• Insulation Parameters: If insulation is applied, users can input the insulation thickness (in mm) and its density (in kg/m³).
