MS Pipe Weight Chart In KG (2025)

Introduction to Mild Steel Pipe

Mild Steel Pipe, often referred to as MS Pipe, is a type of low carbon steel pipe renowned for its excellent strength, ductility, and ease of fabrication. As a versatile material, mild steel pipe is widely used across various industries, including water supply systems, structural construction, mechanical engineering, and general fabrication. The low carbon content in MS pipes makes them easy to weld and form, while still providing the durability required for demanding applications. Whether used in water supply, oil and gas, or as a structural element, MS pipes offer a reliable and cost-effective solution. Understanding the unique properties and broad applications of mild steel pipe is essential for selecting the right material for your project, ensuring both performance and longevity.

Classification of MS Pipe

MS pipes are categorized based on their nominal bore (NB) and wall thickness, which are standardized to meet diverse industry requirements. The classification system helps users select the appropriate pipe for their specific needs, balancing weight, strength, and cost. The most common classifications are Class A (Light), Class B (Medium), and Class C (Heavy). Class A pipes have thinner walls and are lighter, making them suitable for low-pressure applications. Class B pipes offer a medium wall thickness, providing a balance between strength and weight, while Class C pipes feature the thickest walls, delivering maximum strength and durability for heavy-duty and high-pressure uses. Choosing the correct class ensures that the ms pipes will perform optimally in their intended application, whether for water supply, structural support, or industrial use.

MS Pipe Size and Dimensions

MS pipes are available in a wide range of sizes, defined primarily by their outer diameter (OD) and nominal bore (NB). The pipe size and dimensions are crucial factors that determine the pipe’s weight, pressure rating, and suitability for various applications. Wall thicknesses can vary to meet different strength and durability requirements, directly impacting the weight per meter of the pipe. Standard ms pipe sizes typically range from 15mm to 150mm in nominal bore, with corresponding variations in wall thickness and outer diameter. Accurate knowledge of ms pipe sizes, wall thickness, and dimensions is essential for calculating the weight per meter, estimating material requirements, and ensuring the pipe meets the necessary pressure rating for your project. This information is vital for engineers and contractors when planning construction projects, water supply systems, and industrial installations.

How to Calculate MS Pipe Weight per Meter?

You can calculate the weight of any MS pipe using the following formula:

Weight (kg/m) = 0.02466 × (mm OD − wall thickness mm) × wall thickness mm

• mm OD: Outside Diameter in millimeters
• wall thickness mm: Thickness of the pipe wall in millimeters
• 0.02466: Density constant of mild steel (kg/mm³)

This formula ensures precise weight calculation for efficient material handling and cost estimation.

Factors Affecting Mild Steel Pipe Weight

1. Diameter (OD): Larger diameter pipes weigh more due to increased material use.
2. Wall Thickness (wall thickness mm): Thicker walls, measured in millimeters (wall thickness mm), contain more material, increasing the weight.
3. Material Density: MS pipes are made from mild steel, which has a specific density that influences weight.

Properties of Class Pipe

The performance and suitability of a class pipe are determined by its key properties, including wall thickness, outer diameter, and material composition. Class pipes are available in several classes—A, B, and C—each designed for specific applications. Class A pipes, with thinner walls, are ideal for light-duty water supply systems, while Class B pipes offer a medium thickness suitable for general construction and moderate pressure applications. Class C pipes, featuring the thickest walls, are engineered for heavy-duty uses such as gas pipelines and high-pressure construction projects. The choice of class pipe depends on the required strength, durability, and pressure rating, as well as the specific demands of the project. Understanding these properties ensures that the selected pipe will deliver reliable performance and long-term value in any application.

MS Pipe Price and Cost

The price of MS pipes is influenced by several factors, including pipe size, wall thickness, class, and the quality of the material used. Heavier pipes with thicker walls and larger diameters generally cost more due to the increased amount of mild steel required. The ms pipe weight chart is a valuable tool for estimating the total material cost, as it allows buyers to calculate the weight per meter and, consequently, the overall price for their project. Market trends, raw material costs, and the reputation of the leading manufacturer also play a significant role in determining ms pipe price. For construction projects and industrial applications, sourcing ms pipes from a trusted supplier ensures not only competitive pricing but also consistent quality and compliance with industry standards. Accurate weight calculation and understanding of class pipe specifications help in making informed purchasing decisions, optimizing both cost and performance.
