Difference Between GI And MS Pipe

By Utkarsh India

---

The full form of MS stands for Mild Steel, and the full form of GI stands for galvanised Iron pipes, both of which are widely used across the globe for piping and other applications. While both MS and GI pipes are made from low-carbon steel, their processing and usability differ significantly.

GI Pipes

GI pipe full form stands for galvanised Iron Pipe. These pipes are coated with a zinc layer to protect them from corrosion and increase durability. The galvanised iron pipes offer versatility in the form of the dimension in which they are available. The size can range between 15mm and 150mm. Apart from being lightweight and economical, these pipes are known for easy installation, hence making them extremely useful for water transportation in rural regions. Despite their zinc coating, care should be taken so that they are not installed in highly acidic conditions, or it will lead to corrosion.

GI pipes are apopular choice for water supply systems due to their exceptional corrosionresistance. These pipes are constructed from zinc-coated steel, making themhighly resistant to rust, even when exposed to moisture and harsh environmentalconditions. This corrosion resistance ensures the long-term durability andreliability of GI pipes in water supply, making them an ideal choice fortransporting clean and potable water in residential, commercial, and industrialsettings.

Features of Galvanized Iron pipes:

·        Higher longevity and Durability.

·        Anti-rust coating and superior finish

·        Resistant to corrosion

·        Easy to weld and fabricate

Here are the primary uses of GI pipes:

·        Water & Sewage transportation

·        Structural purposes

·        Automotive purposes

·        Engineering purposes

·        Oil & Gas transmission

·        Electric Poles 

MS Pipes

MS pipe full form stands for Mild Steel Pipe. With less than 0.25% carbon content, these pipes are malleable, ductile, and robust. While GI (full form for galvanised Iron) pipes can be welded into various shapes and sizes as per the requirement, Mild Steel pipes are generally used for plumbing, firefighting, and HVAC (heating, ventilation, and air conditioning). These pipes are also coated with paints, varnish, or other metals that protect them from corrosion and make them long-lasting and resist critical conditions. Thanks to their flexibility, they can be welded into various shapes and sizes, making them indispensable in the construction industry.

GI Pipe Vs MS Pipe

MS and GI pipes are widely used all across the globe forpipelines and other operations. While the former is made from mild carbonsteel, the latter is coated with zinc to prevent corrosion.

Point of difference	Explanation
Composition	The difference between GI and MS pipes in terms of composition is that GI pipes are made up of low-carbon steel with a zinc coat, and MS pipes are made of mild steel with 0.25% carbon.
Uses	The GI pipes are used in water supply systems, plumbing, and in environments requiring corrosion resistance, whereas MS pipes are used in structural framing, pipelines, industrial machinery, and HVAC systems.
Corrosion Resistance	While the GI pipe is highly resistant to rust and corrosion due to its zinc coating, the MS pipe is prone to corrosion unless it is covered with varnish or paint.
Ease of use	The GI pipes are lightweight, easy to install, and ideal for long-distance transport, whereas the MS pipes are heavier, durable, and suitable for complex applications.
Welding	The MS pipes are easier to weld and put into shape as needed.
Weight	The GI pipes are much lighter than the MS pipes.
Size	The GI pipes are available in sizes ranging from 15 mm to 150 mm, as per their fittings specifications. The MS pipes can be manufactured in various shapes and sizes as per their fittings specifications.

Conclusion

MS and GI pipes are widely used all across the globe forpipelines and other operations. While the former is made from mild carbonsteel, the latter is coated with zinc to prevent corrosion.
