What is MS Rectangular Pipe?
MS rectangular pipe, also known as mild steel rectangular pipe, is a hollow structural profile (HSS) made of mild steel. They are made from mild steel, which is a type of carbon steel with low carbon content, making it ductile and easy to weld and shape.
MS pipes are pipes made from steel, which has a carbon content of less than 0.25%. There are different grades of mild steel depending upon the carbon content present in the steel. Rectangular tubes can be divided into two types: seamless rectangular tubes and welded rectangular tubes according to the production process. According to different cross-sectional shapes, they can be divided into square tubes and rectangular tubes. Other elements may be added to this steel for enhancing its corrosion resistance, wear resistance and tensile strength. The high level of weldability and machinability of this type of steel makes it highly suitable for a range of applications including piping and tubing.
Properties of Rectangular MS Steel Pipes
1. Material Composition
Mild Steel: Composed primarily of iron with a small percentage of carbon (typically 0.16-0.29%), mild steel is known for its malleability and ductility, making it easy to weld, cut, and form.
2. Dimensions
Width x Height: Rectangular pipes are defined by their external dimensions, usually given as width x height.
Thickness: The thickness of the pipe wall can vary, influencing the pipe's strength and weight.
Length: Typically available in standard lengths, which can be cut to size as required.
3. Mechanical Properties
Tensile Strength: Typically ranges between 345-690 MPa, depending on the grade of the steel used.
Yield Strength: Often around 250 MPa for general structural use.
Ductility: Mild steel has good ductility, allowing it to deform under stress without breaking.
Hardness: Lower hardness compared to high-carbon steels, but still sufficient for most structural purposes.
4. Physical Properties
Density: Approximately 7.85 g/cm³, similar to other carbon steels.
Thermal Conductivity: Moderate thermal conductivity, around 50 W/m·K.
Electrical Conductivity: Relatively low electrical conductivity compared to other metals like copper.
5. Corrosion Resistance
Corrosion Resistance: Mild steel is not inherently corrosion-resistant. It is often coated, painted, or galvanized to improve its resistance to rust and corrosion in exposed environments.
6. Weldability
Weldability: MS steel pipes have excellent weldability, making them ideal for structural applications that require joints and connections.
7. Advantages
Strength-to-Weight Ratio: Offers a good balance of strength and weight, making it suitable for load-bearing structures.
Cost-Effective: Relatively low cost compared to other steels and metals, making it an economical choice.
Versatility: Can be used in a wide range of applications, easily customized to different shapes and sizes.
8. Limitations
Corrosion: Needs protection against rust in humid or corrosive environments.
Weight: Heavier than materials like aluminum, which may be a drawback in some applications.
Applications of Rectangular MS Steel Pipes
1. They are used for structural purposes such as making industrial sheds. Rectangular MS pipes can be used for making strong frames and the shed can be completed with steel sheets.
2. They are used for making bridges.
3. They are used extensively in making radio masts and telecom towers.
4. They are used in creating a mine roof support system.
5. They are needed for constructing scaffoldings.
6. They can also be used for constructing fences.
7. They can also be used in pipeline transportation.
Overall, rectangular MS steel pipes are a reliable and versatile choice for many structural and manufacturing needs, providing a balance of strength, formability, and cost-effectiveness.
