1.Product Overview

Stainless steel pipes (SS pipes) are high-performance tubular products made from corrosion-resistant steel alloys. They are widely used in industries requiring durability, hygiene, and resistance to extreme environments.

Key Features:

✔ Corrosion Resistance – Excellent performance in acidic, alkaline, and chloride-rich environments

✔ High Strength – Withstands high pressure and mechanical stress

✔ Hygienic & Easy to Clean – Ideal for food, pharmaceutical, and medical applications

✔ Temperature Resistance – Suitable for cryogenic to high-temperature applications

✔ Aesthetic Appeal – Polished finishes available for architectural use

2. Material Grades & Standards

Grade	Equivalent (EN/AISI)	Key Properties	Common Applications
304	1.4301 (EN) / AISI 304	Excellent formability, weldability	Food processing, chemical tanks
304L	1.4307 / AISI 304L	Low carbon, better weldability	Petrochemical, pharmaceuticals
316	1.4401 / AISI 316	Superior chloride resistance	Marine, coastal, medical
316L	1.4404 / AISI 316L	Low carbon, high corrosion resistance	Offshore, desalination plants
321	1.4541 / AISI 321	Titanium-stabilized, heat-resistant	High-temperature exhaust systems
Duplex 2205	1.4462	High strength, chloride resistance	Oil & gas, chemical processing

Standards Compliance:
