When selecting steel pipes for construction, plumbing, or industrial projects, understanding pipe weight is critical for both structural design and transportation planning. One of the most commonly used specifications in the industry is Schedule 40 steel pipe. But what exactly is the weight of a Schedule 40 steel pipe—and how do you calculate it?
What Is Schedule 40 Steel Pipe?
Schedule 40 steel pipe refers to a standard wall thickness as defined by the ANSI/ASME B36.10 and B36.19 pipe schedules. It is widely used in various applications such as gas lines, water distribution, and structural frameworks due to its balance of strength and weight.
Material: Carbon steel or galvanized steel
Common standards: ASTM A53, A106, API 5L
Schedule 40 is often the go-to choice for general-purpose pressure and mechanical applications.
Weight Factors: What Affects the Pipe Weight?
The weight of a Schedule 40 pipe depends on three main factors:
Pipe size (outer diameter)
Wall thickness
Material density
The formula used to estimate steel pipe weight per meter is:
Weight (kg/m) = (OD - WT) × WT × 0.02466
Where:
OD = outer diameter (mm)
WT = wall thickness (mm)
0.02466 = steel density constant (for carbon steel)

Why Is Pipe Weight Important?
Understanding the weight of Schedule 40 steel pipe is essential for:
Project load calculations
Transport and logistics planning
Pipe support design
Cost estimation
Whether you’re managing a small plumbing job or designing a large-scale industrial facility, accurate weight data helps avoid costly errors and ensures safety compliance.
