Product Guide & Technical Article

Complete Guide to Stainless Steel Pipes & Tubes

Stainless steel pipes and tubes are the backbone of modern industrial infrastructure. From chemical plants to power generation, these components ensure safe and efficient fluid transport across demanding environments.

What Are Stainless Steel Pipes & Tubes?

Pipes and tubes are hollow cylindrical products used to convey fluids, gases, and slurries. While pipes are measured by nominal bore (NB) size, tubes are measured by their outer diameter (OD). Both are available in seamless and welded forms, each suited to specific pressure and application requirements.

Key Grades & Standards

The most widely used grades include SS 304/304L for general corrosion resistance, SS 316/316L for chloride environments, SS 321 for high-temperature service, and Duplex 2205 for combined strength and corrosion resistance. Standards include ASTM A312, ASTM A213, and ASTM A269.

Applications

Stainless steel pipes and tubes are used across oil & gas, petrochemical, pharmaceutical, food processing, power generation, marine, and construction industries. Their corrosion resistance, hygiene properties, and high strength make them the preferred choice for critical piping systems.
