Calculate pipe weight

Calculate the weight of individual pipes and the entire pipeline made of carbon steel pipes. Select the nominal pipe diameter from the available form. The calculator shows the outside and inside diameter of the pipe for a standard pipe weight. For other pipe weight than standard SCH 40 select one from the list below the form.

After that, enter the actual length of the pipe or pipeline for the selected nominal diameter and pipe weight. The calculator will display the unit weight of the pipe per length meter, as well as the total weight of the pipe or piping for the total length entered.

Pipe nominal size

Pipe length (L)

Pipe unit weight (W/L)

Outside diameter (OD)

Wall thickness (wt)

Empty pipe weight (W)

Calculate pipe price

If you enter the unit price of the pipe in USD per unit mass of the pipeline, the calculator will display the total price of the pipe or pipeline. This way you can use the calculator to make the budget estimate for your project.

Steel price (USD)

Total pipe price (USD)

Filled pipe weight

The calculator also allows you to calculate the weight of the pipeline with the fluid inside the pipe. For a known fluid, you need to enter the density of the fluid and the calculator will calculate the volume of the fluid in the pipe, as well as the total mass of the pipeline with the fluid.

Fluid density (ρ)

Filled pipe weight (Wf)

Volume of the fluid (V)

Pipes list

If the pipeline consists of several different dimensions of the pipeline, a table is available in which several different sizes and lengths of the pipelines can be added. The table presents the individual pipe parameters as well as the total summary values.

Enquire for pipe material

You can send the RFP created in this way to me and ask for an offer with the delivery time and additional requirements, such as the place of delivery, the name of the project and other parameters that are important for the purchase order.
