Mild Steel Pipe – Types, Uses, Sizes, Prices & Industrial Guide by Udhhyog
Mild Steel Pipe are one of the most essential elements in any construction, infrastructure, or industrial project. Whether it’s carrying water, gas, steam, oil, or structural load, the pipe plays a key role in our everyday lives and in the world of manufacturing and engineering. In this complete guide, Udhhyog brings you detailed insights into types of pipes, their material composition, uses, standard sizes, pricing, and selection guide—especially for commercial and industrial buyers.
1. What is a Pipe?
A pipe is a hollow cylindrical structure used to transport fluids (liquids or gases), powders, or even structural forces. Pipes are commonly measured by nominal bore (NB), outside diameter (OD), wall thickness, and schedule (SCH). They can be made from metals like steel, stainless steel, copper, and non-metallic materials like PVC, HDPE, and more.
The word pipe is often used interchangeably with tube, but in industrial terminology, they are slightly different in terms of tolerances and usage.

2. Types of Pipe by Material
Different materials are used depending on the application:
a. Mild Steel Pipe (MS Pipe)
- Widely used in construction and structural applications.
- Conforms to IS 1239, IS 3589 standards.
- C Class, B Class, and A Class pipes are available based on wall thickness.
b. Galvanized Iron Pipe (GI Pipe)
- MS pipe with zinc coating.
- Used in plumbing, fencing, and water supply systems.
- Corrosion resistant.
c. Stainless Steel Pipe (SS Pipe)
- Grades: SS 304, SS 316, SS 202.
- Suitable for chemical, pharma, and food industries.
- High corrosion resistance.
d. PVC, CPVC, UPVC Pipe
- Used in residential and light commercial plumbing.
- Lightweight and cost-effective.
- CPVC is suitable for hot water.
e. HDPE Pipe
- High-density polyethylene.
- Used in agriculture, water supply, and underground systems.
f. Ductile Iron Pipe (DI Pipe)
- High-strength and durable.
- Mostly used in water and wastewater networks.
g. Copper Pipe
- Excellent for heating and refrigeration.
- Used in HVAC and gas lines.
