LSAW Steel Pipe Weight Chart

1. Common LSAW Pipe Weights

LSAW pipe weight depends on outside diameter, wall thickness, and steel density. The table below lists the theoretical weight per meter for common LSAW pipe sizes.

Note: The values above are theoretical weights. Actual pipe weight may vary depending on manufacturing tolerances and the applicable standard.

2. LSAW Steel Pipe Weight Chart

The following tables list the theoretical weight of common LSAW steel pipes by nominal pipe size (NPS), outside diameter (OD), and wall thickness (WT). The charts provide quick reference values for engineering calculations, material estimation, and transportation planning.

2.1 Medium Diameter LSAW Pipe Weight Chart (NPS 14"–24")

The following sizes are commonly used for oil & gas transmission pipelines, water transmission, and general industrial applications.

2.2 Large Diameter LSAW Pipe Weight Chart (NPS 26"–36")

These sizes are widely used for cross-country pipelines, long-distance transmission lines, and heavy industrial projects where larger diameters and higher pressure ratings are required.

2.3 Structural & Heavy-Duty LSAW Pipe Weight Chart (NPS 40"–56")

Large-diameter heavy-wall LSAW pipes in this range are commonly selected for bridge foundations, offshore structures, pipe piling, and other heavy engineering applications.

2.4 Ultra-Large Diameter LSAW Pipe Weight Chart (NPS 60"–100")

Ultra-large diameter LSAW pipes are typically manufactured for marine engineering, offshore platforms, water transmission, and large infrastructure projects. Availability depends on mill capability and project specifications.

Engineering Notes

For project planning and logistics, theoretical weight is suitable for preliminary calculations. For procurement, transportation, and lifting operations, the manufacturer's certified pipe weight should always be used.

3. LSAW Pipe Weight Formula

The theoretical LSAW pipe weight per meter (kg/m) is calculated from the outside diameter (OD), wall thickness (WT), and the density of carbon steel. The formula below is widely used for engineering estimation, material take-offs, transportation planning, and preliminary project costing.

Actual pipe weight may vary slightly due to manufacturing tolerances, weld reinforcement, end preparation, coatings, and other project-specific requirements. For procurement and lifting operations, the manufacturer's certified pipe weight should always be used.

Calculation Basis

- Steel Density: 7,850 kg/m³ (7.85 g/cm³)

- Theoretical Weight (kg/m):

W = (OD − WT) × WT × 0.0246615

Where:

- OD = Outside Diameter (mm)

- WT = Wall Thickness (mm)

For a standard 12 m pipe:

Pipe Weight (12 m) = Weight (kg/m) × 12

Calculation Example

For a 24 in (609.6 mm) LSAW steel pipe with a 12.7 mm wall thickness:

Weight (kg/m) = (609.6 − 12.7) × 12.7 × 0.0246615 ≈ 186.9 kg/m

For a standard 12 m pipe:

Pipe Weight = 186.9 × 12 ≈ 2,243 kg

4. Custom LSAW Pipe Weight

Most LSAW steel pipes are manufactured in standard sizes, but project requirements do not always match standard dimensions. Custom outside diameters, wall thicknesses, and pipe lengths are common in offshore, structural, and large infrastructure projects.

If you need a custom LSAW pipe weight table or a quotation for project-specific dimensions, our engineering team can provide the corresponding weight data together with manufacturing recommendations.

5. FAQS

Q1. How do you calculate LSAW pipe weight?

LSAW pipe weight is calculated from the outside diameter (OD), wall thickness (WT), and steel density. Standard weight charts and formulas provide the theoretical weight per meter for common pipe sizes.

Q2. Is the weight chart theoretical or actual?

The values in this chart are theoretical weights. Actual pipe weight may vary slightly due to manufacturing tolerances, weld reinforcement, coatings, and end preparation.

Q3. Does API 5L specify LSAW pipe weight?

No. API 5L specifies pipe dimensions and manufacturing requirements. Theoretical weight is calculated from the specified outside diameter and wall thickness.

Q4. Why are heavier-wall LSAW pipes much heavier?

Increasing wall thickness adds steel around the entire circumference of the pipe, so weight increases significantly even when the outside diameter remains the same.

Q5. Can custom LSAW pipe weights be calculated?

Yes. Theoretical weight can be calculated for custom outside diameters, wall thicknesses, and lengths based on the project specifications.

Q6. Are LSAW pipe weights available in both kg/m and lbs/ft?

Yes. LSAW pipe weight is commonly expressed in both kg/m and lbs/ft to support metric and imperial engineering standards.
