MS pipe, or Mild Steel pipe, is a hollow cylindrical steel section manufactured by electric resistance welding (ERW) or seamless process. It is classified under IS 1239 Part 1 and is one of the most widely used structural and utility pipes across construction, plumbing, industrial, and fabrication applications in India. When searching for a pipe size ms pipe weight chart in kg, IS 1239 is the standard reference.
MS pipes are sold by Nominal Bore (NB) — which is an approximate internal diameter designation — and are available in three weight classes based on wall thickness: Light, Medium, and Heavy. The weight per metre varies by both nominal bore and the class chosen. Understanding this is essential before reading any weight chart table.
Thinner walls, lower weight. Used for low-pressure water lines, conduit purposes, and general light-duty structural applications where pressure rating is not a concern.
Standard specification. The most commonly supplied and purchased class. Suitable for water supply, gas lines (low pressure), scaffolding, fencing, and general fabrication.
Thickest walls, highest pressure rating. Used in high-pressure pipelines, structural columns, heavy fabrication, fire-fighting lines, and industrial piping systems.

The Nominal Bore (NB) is not the actual internal diameter — it is a size designation only. The actual outer diameter (OD) and wall thickness determine the real internal bore and the weight. Always refer to OD and wall thickness when specifying for engineering or structural applications.

To convert values from this pipe size ms pipe weight chart in kg per metre to kg per foot, multiply by 0.3048. For example: 50mm Medium class pipe at 5.03 kg/m = 5.03 × 0.3048 = 1.53 kg/foot. Bookmark this pipe size ms pipe weight chart in kg for quick on-site reference.
Formula for Sizes Not in the Pipe Size MS Pipe Weight Chart in KG
If you need to calculate the weight of an MS pipe size not listed in the pipe size ms pipe weight chart in kg above — or need to verify a specific wall thickness — use the standard steel pipe weight formula. This is the same formula used to build every pipe size ms pipe weight chart in kg table:
To calculate total weight for a quantity of pipes using the pipe size ms pipe weight chart in kg:
Total Weight (kg) = Weight per metre (kg/m) × Length (m) × Number of pipes
For example: 10 pipes of 25mm Medium class, each 6 metres long = 2.41 × 6 × 10 = 144.6 kg total. Always cross-check with the pipe size ms pipe weight chart in kg before placing a bulk order.
