Difference between GI and MS Pipe

Understanding the Difference between GI and MS Pipe is essential for anyone involved in plumbing, fire-fighting systems, industrial piping, fabrication, or construction. Both types of pipes are widely used across different industries, yet they differ significantly in material composition, corrosion resistance, cost, installation requirements, and long-term performance. ππ§
Choosing the right pipe type can directly impact the safety, durability, and efficiency of a project. This is why understanding the Difference between GI and MS Pipe becomes crucial before planning SITC (Supply, Installation, Testing & Commissioning). π οΈβ¨
Introduction to the Difference between GI and MS Pipe
Before comparing the two, letβs understand the materials π€:
-
GI Pipes (Galvanized Iron) are steel pipes coated with a protective layer of zinc to prevent rusting.
-
MS Pipes (Mild Steel) are low-carbon steel pipes known for their strength, flexibility, and ease of fabrication.
Both GI and MS pipes are common in plumbing, fire-fighting, HVAC, compressed air systems, water supply lines, and structural frameworks. However, the Difference between GI and MS Pipe influences where and how each type should be used. π₯π‘
What is a GI Pipe?
A GI pipe is a metal pipe coated with zinc through a galvanization process. This zinc coating acts as a protective barrier between the iron and the atmosphere. π¦π‘οΈ
πΉ Key Features:
-
High corrosion resistance π
-
Longer lifespan in water-related applications
-
Suitable for outdoor installations π€οΈ
-
Relatively heavier compared to MS
-
Not ideal for welding due to zinc fumes β οΈ
GI pipes are widely used in water supply lines, residential plumbing, fencing, and some fire-fighting setups depending on approvals.
What is an MS Pipe?
MS pipes are made from mild steel, which contains a low carbon percentage. They are uncoated and therefore more prone to corrosion unless painted or coated on-site. π¨π§°
πΉ Key Features:
-
High tensile strength πͺ
-
Easy to weld and fabricate π₯
-
Lower cost compared to GI π°
-
Lightweight and flexible for installation
-
Used extensively in fire-fighting systems, industrial pipelines, structural frameworks, and HVAC piping
MS is preferred in scenarios where custom fabrication or heavy-duty strength is required.
Major Difference between GI and MS Pipe
Here are the key differences presented in a clear comparison π:
Material Composition
The major Difference between GI and MS Pipe starts with their core material.
-
GI pipes = Mild steel + Zinc coating
-
MS pipes = Mild steel without coating
Corrosion Resistance
-
GI pipes are designed to resist corrosion due to the zinc coating π
-
MS pipes need external protection such as paint or epoxy coating
This is one of the most important Difference between GI and MS Pipe when planning long-term projects.
Weldability
MS pipes are easier to weld, making them suitable for fabrication-heavy projects π§
GI pipes are more difficult to weld because the zinc coating produces toxic fumes when heated β οΈ
Durability
-
GI pipes last longer in water-based applications πΏ
-
MS pipes are more durable in structural and high-pressure scenarios π₯
Cost
-
GI pipes are costlier because of galvanization
-
MS pipes are more budget-friendly π―
Weight
-
GI pipes are heavier
-
MS pipes are comparatively lighter and easy to handle π
Applications Based on the Difference between GI and MS Pipe
Because of the Difference between GI and MS Pipe, their applications vary π:
πΈ GI Pipe Uses:
-
Domestic water supply π°
-
Handrails, guard rails
-
Rural water distribution
-
Light structural support
-
Outdoor pipelines π¦οΈ
πΈ MS Pipe Uses:
-
Fire-fighting systems (hydrant + sprinkler) π₯π
-
Industrial piping
-
Fabrication and custom installations
-
HVAC pipelines βοΈ
-
Compressed air systems
Understanding these differences ensures that you select the right pipe type for long-term reliability and safety.
