Steel Pipes vs. Mild Steel Pipes: Key Differences, Uses, and Benefits

 

Introduction

Steel pipes are widely used in various industries, but not all steel pipes are the same. Mild steel (MS) pipes differ in composition, properties, and applications. This guide explains the key differences, uses, and benefits of steel pipes vs. mild steel pipes to help you make the right choice for your project.

What Are Steel Pipes?

Steel pipes are cylindrical tubes made from steel alloys, designed for fluid transportation, structural applications, and industrial use.

Properties of Steel Pipes:

  • Material: Alloy steel, carbon steel, or stainless steel

  • Strength: High tensile and compressive strength

  • Corrosion Resistance: Depends on alloy composition (stainless steel resists rust best)

  • Durability: Long-lasting with proper coating

Common Uses of Steel Pipes:

  • Oil & gas pipelines

  • Structural frameworks

  • High-pressure water and steam transport

  • Industrial machinery

What Are Mild Steel (MS) Pipes?

MS pipes are a type of low-carbon steel pipe known for their affordability and ease of welding.

Properties of MS Pipes:

  • Material: Low-carbon steel (0.05%–0.25% carbon content)

  • Strength: Moderate tensile strength

  • Corrosion Resistance: Requires coating for rust prevention

  • Weldability: Excellent, making them easy to fabricate

Common Uses of MS Pipes:

  • Plumbing and water supply

  • Structural support in buildings

  • Fencing and handrails

  • Automobile and industrial applications

Benefits of Using Steel Pipes

  • High strength and durability for heavy-duty applications

  • Resistant to high temperatures and pressure

  • Corrosion-resistant when using stainless steel

  • Suitable for oil, gas, and industrial applications

Benefits of Using MS Pipes

  • Affordable and cost-effective

  • Easy to weld and fabricate

  • Lightweight compared to alloy steel

  • Ideal for general-purpose and structural applications

How to Choose Between Steel and MS Pipes?

  1. For high-pressure and corrosive environments → Choose stainless steel pipes.

  2. For cost-effective and lightweight structures → Choose MS pipes.

  3. For industrial and chemical applications → Opt for alloy steel pipes.

  4. For plumbing and fencing → MS pipes work best.

Industry Standards and Grades

Common Steel Pipe Grades:

  • Stainless Steel: SS304, SS316

  • Carbon Steel: ASTM A106, API 5L

  • Alloy Steel: ASTM A335

Common MS Pipe Grades:

  • IS 1239 (Mild Steel Tubes for Structural Use)

  • IS 3589 (MS Pipes for Water and Sewage)

  • ASTM A36 (Mild Steel Sheets & Pipes)

Frequently Asked Questions (FAQs)

1. Which is stronger, steel pipes or MS pipes?

Steel pipes, especially alloy or stainless steel, are stronger than mild steel pipes due to their higher tensile strength and corrosion resistance.

2. Can MS pipes be used for underground applications?

Yes, but they require proper coatings (galvanization or epoxy) to prevent rust and corrosion.

3. Are MS pipes suitable for drinking water supply?

Yes, but they should be coated internally with anti-corrosion material to ensure safe water transport.

4. What is the lifespan of MS pipes compared to steel pipes?

MS pipes last around 15-25 years, whereas stainless steel pipes can last 50+ years with proper maintenance.

5. Where can I buy steel and MS pipes in bulk?

You can purchase from platforms like Udyog Lines, TradeIndia, and Justdial for bulk orders from verified manufacturers.

Check Valve (Non-Return Valve): Types, and Pricing

  Introduction A check valve , also known as a non-return valve (NRV) , is a mechanical device that allows fluid to flow in only one direction, preventing backflow. It is commonly used in pipelines, water supply systems, industrial processes, and pumps to maintain directional flow and prevent equipment damage due to reverse flow. Check Valve Symbol The check valve symbol used in engineering diagrams consists of a valve body with an arrow indicating the permitted flow direction and a barrier preventing reverse flow. It is commonly seen in process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs). Types of Check Valves (Non-Return Valves) There are several types of check valves (NRVs) designed for specific applications: Swing Check Valve – Uses a hinged disc that swings open with forward flow and closes when the flow reverses. Dual Plate Check Valve – Features two spring-loaded plates that automatically open and close with the...
