A contractor once told me how his entire project paused for two days.
The reason was simple.
His supplier delivered the wrong pipe category, causing leaks during testing.
That moment made him realize the importance of choosing the correct c class pipe for pressure-driven applications.
This guide helps you avoid the same delay.
What Is an MS C Class Pipe?
C class pipes are heavy-grade mild-steel pipes designed for high-pressure flow.
They are used where durability is essential and failure would cause losses.
These pipes are thicker than A and B class categories.
HSN Code for MS C Class Pipe: 7306
This HSN code is used in GST classification for seamless and welded steel pipes.
(Ref: Ministry of Finance – GST Tariff Schedule)
Applications of C Class Pipe
C class pipe is trusted in heavy-load and high-pressure environments.
Below are primary B2B applications:
Industrial Use
Factories use these pipes for compressed air lines and chemical flow.
They handle internal pressure without deformation.
Construction Sector
Contractors choose them for riser lines, fire-fighting systems, and structural purposes.
Their thickness supports stability in high-rise projects.
Plumbing & Infrastructure
Engineers install c class pipe for municipal water supply, drainage, and borewell casing.
Fabrication Industry
Fabricators prefer them for heavy machine frames and material-handling structures.

Thickness Comparison Table
| Pipe Type | Wall Thickness | Pressure Handling | Typical Usage |
|---|---|---|---|
| A Class | Thin | Low pressure | Light plumbing, small structures |
| B Class | Medium | Moderate pressure | Domestic supply, fabrication |
| C Class | Thickest | High pressure | Industrial, heavy construction, fire systems |
(Thickness values vary by size; IS 1239 standard used for reference.)
Price Guide for MS C Class Pipe (2025)
Prices depend on diameter, weight per meter, and steel grade.

Factors Affecting C Class Pipe Price
Keep sentences short (under 20 words) and sections tight.
1. Raw Material Cost
Fluctuation in hot-rolled coil pricing affects pipe manufacturing cost.
Steel demand increases during infrastructure growth phases.
2. Pipe Diameter & Weight
Heavier pipes require more steel per meter and cost more.
Large diameters sharply increase pricing.
3. Manufacturing Standard
IS 1239 certified pipes cost more than non-standard options.
Buyers choose certified pipes for safety.
4. Coating & Treatment
Galvanizing, varnish coating, or oiling increase cost.
Fire-fighting and industrial projects often require coated products.
5. Transport & Logistics
Distance from mill to site affects final quotation.
High fuel prices increase logistics charges.
Why This Article Is Important for B2B Buyers
