GI Pipes vs MS Pipes – Price & Performance Comparison

 

Introduction

Choosing between GI (Galvanized Iron) pipes and MS (Mild Steel) pipes depends on cost, durability, and application. Understanding their differences helps businesses, traders, and Udhhyog industries make better purchasing decisions.

Key Differences Between GI Pipes & MS Pipes

FactorGI PipesMS Pipes
CoatingZinc-coated for rust resistanceNo coating, prone to corrosion
StrengthHigher due to galvanizationModerate
LifespanLonger (15-20 years)Shorter (5-10 years)
PriceSlightly higherMore affordable
ApplicationWater supply, fencingStructural, construction

Factors Affecting GI & MS Pipe Prices

1. Raw Material Costs

  • GI pipes are costlier due to zinc coating.

  • MS pipes are cheaper but require maintenance to prevent rust.

2. Manufacturing Process

  • GI Pipes: Hot-dipped galvanization increases cost but enhances durability.

  • MS Pipes: Simple manufacturing makes them affordable but less corrosion-resistant.

3. Market Demand & Supply

  • GI pipes are preferred in plumbing & water transport, impacting demand.

  • MS pipes are widely used in the Udhyog sector and construction industries.

4. Import & Export Duties

  • Higher import duties on steel impact GI and MS pipe pricing.

  • Global trade policies affect supply chain costs.

5. Performance & Longevity

  • GI Pipes: Long-lasting and corrosion-resistant, suitable for outdoor use.

  • MS Pipes: Require painting or coating for rust prevention, reducing lifespan.

How to Choose Between GI & MS Pipes

  1. For Corrosion Resistance – Choose GI pipes for outdoor and water applications.

  2. For Cost-Effective Solutions – MS pipes are cheaper but require maintenance.

  3. For Long-Term Use – GI pipes have a longer lifespan.

  4. For Heavy-Duty Applications – MS pipes are better for structural projects.

  5. For Udhyog & Industrial Use – Both have specific applications based on project needs.

Applications of GI & MS Pipes

  • GI Pipes: Plumbing, fencing, irrigation, and outdoor applications.

  • MS Pipes: Industrial structures, automotive frames, and fabrication work.

FAQs

1. Which is better, GI or MS pipe?

GI pipes last longer and resist corrosion, while MS pipes are affordable but require maintenance.

2. Why are GI pipes more expensive than MS pipes?

The zinc coating process increases the cost of GI pipes compared to MS pipes.

3. Which pipe is stronger, GI or MS?

GI pipes are stronger due to galvanization, while MS pipes need coatings to enhance durability.

4. What is the lifespan of GI vs MS pipes?

GI pipes last 15-20 years, whereas MS pipes last 5-10 years with maintenance.

5. Can MS pipes be used for water supply?

MS pipes are not ideal for water transport unless coated to prevent rusting.

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...
