Steel & Stainless Steel Pipes & Fittings

What are steel and stainless steel pipe fittings?

Steel fittings handle higher pressures and temperatures than plastic, so plants use them for steam, compressed air, fuel and process lines. Stainless steel contains chromium, which forms a thin protective layer that resists rust. Grade 304 suits most water and food uses, while grade 316 adds molybdenum for better resistance to chlorides.

Steel fittings either screw on with threads or weld on. Threaded fittings suit smaller sizes and quick repairs. In contrast, butt-weld and seamless fittings suit larger, high-pressure lines, and their wall thickness is matched to the pipe schedule.

How to choose steel pipes and fittings

• Pick stainless steel for corrosion resistance and hygiene, and carbon steel for strength at lower cost.
• Choose grade 316 for coastal sites, salty water or many chemicals.
• Match the fitting schedule or class to the pipe and the line pressure.
• Use threaded fittings for small sizes and butt-weld fittings for large or high-pressure lines.
• Avoid mixing stainless and carbon steel without isolation, which can cause corrosion.
• Ask for mill certificates if your project needs material traceability.
