MS Pipe Weight Chart

Mild steel pipe is abbreviated as "MS pipe." Chemical composition of MS pipe is carbon, silicon, manganese, phosphorus, and sulfur, with a carbon content of less than 0.25%. It exhibits excellent ductility, toughness, and strength, making it widely used in construction, machinery, petroleum, water supply and drainage, and infrastructure engineering. Understanding the weight of MS pipe is crucial for structural design, transportation calculations, and project cost assessments.

What is Mild Steel Pipe?

MS pipe (mild steel pipe) is made from mild steel and has the following properties:

1. Easy to weld and form

Suitable for various welding processes (such as ERW and SAW).

2. Low cost

More economical than stainless steel and alloy steel.

3. Excellent strength and toughness

Strong compressive and bending resistance.

4. Wide range of applications

Building support, pipeline transportation, water well pipes, machinery manufacturing, scaffolding, etc.

MS Pipe Weight Tolerances

This means that there is a certain allowable error between steel pipes from different manufacturers and different batches.

MS Pipe Weight Chart in KG/Meter

The formula for calculating the weight of mild steel pipe is:

Weight of mild steel pipe (g) = π × (outer diameter - wall thickness) × wall thickness × length × density

The following chart shows the weight per meter (kg/m) of light (Class A), medium (Class B), and heavy (Class C) mild steel pipe in metric (mm) and imperial (inch) standards.

Comparing the weight of SCH 40, SCH 80, and SCH 160 mild steel pipes of different pressure grades.

"Schedule (SCH)" represents the pipe wall thickness grade. Common standards are as follows:

SCH 40: Standard thickness, suitable for conveying normal pressure fluids.

SCH 80: Thickened type, used in high-pressure systems.

SCH 160: Extra-thick type, suitable for extremely high pressure or deep well systems.

Recommendation: When selecting pipe, choose the appropriate SCH grade based on the operating pressure, temperature, and media type.

FAQ
