Stainless Steel 317L Pipe Industrial Applications

317L stainless steel pipe serves 5 major industries where acidic or chloride-rich conditions demand performance beyond 316L.

Chemical & Petrochemical Processing

Chemical plants use Alloy 317L pipe for sulphuric acid, phosphoric acid, and chloride-bearing process streams in reactor piping and heat exchanger lines.

Pulp & Paper Industry

Bleaching stages in pulp mills expose piping to chlorine dioxide and hypochlorite. Type 317L pipe handles these conditions without the pitting failures that affect lower-molybdenum grades.

Power Generation

Flue gas desulphurisation (FGD) systems and condenser tubing in power plants rely on 317L pipe for resistance to acidic condensates in scrubber environments.

Oil & Gas

Downstream processing and fluid catalytic cracking (FCC) units use 317L pipe where naphthenic acid and chloride-bearing crude fractions are present.

Food Processing

SS 317L pipe's resistance to citric, lactic, and organic acids makes it suitable for sanitary process lines in food-grade piping systems.

317L vs 316L Stainless Steel Pipe – Comparison for Buyers

317L pipe carries higher molybdenum (3.0–4.0% vs 2.0–3.0%) and nickel (11.0–15.0% vs 10.0–14.0%) than 316L, providing stronger corrosion resistance in chloride and acidic environments at a 15–25% price premium.

Property 317L 316L
Molybdenum 3.0–4.0% 2.0–3.0%
Nickel 11.0–15.0% 10.0–14.0%
Chromium 18.0–20.0% 16.0–18.0%
Carbon (max) 0.030% 0.030%
Chloride Pitting Resistance Superior Good
Cost 15–25% higher Baseline
