All SS Pipe Sizes in One Chart – Seamless & ERW | Udhhyog India

 

When working with stainless steel (SS) pipes, selecting the right size is crucial for system compatibility, flow requirements, and installation accuracy. Whether you're in fabrication, plumbing, infrastructure, or industrial projects, having access to a complete SS pipe size chart for seamless and ERW pipes simplifies the process.



At Udhhyog India, we supply SS seamless and ERW pipes in all standard sizes, thicknesses, and finishes. This comprehensive guide includes our verified size chart, applicable standards (IS/ASTM), and downloadable reference tables for engineers, buyers, and contractors.

🔍 What Are Seamless and ERW Stainless Steel Pipes?

🔧 SS Seamless Pipe:

Manufactured without welding, seamless pipes offer uniform strength and pressure handling. Made by extrusion or hot rolling, they are ideal for:

  • High-pressure fluid systems

  • Oil & gas pipelines

  • Boiler and heat exchanger tubes

  • Pharma and sanitary pipelines

🔩 SS ERW Pipe:

ERW (Electric Resistance Welded) pipes are formed by rolling SS coils and welding the seam. ERW pipes are widely used due to cost efficiency, availability in large diameters, and smooth internal finish.

📌 Udhhyog supplies both types across all major grades: SS 304, 316, and 202.
