Introduction

Incoloy 926 Pipe (also Alloy 926 Pipe, UNS N08926 Pipe, EN 1.4529 Pipe, Super Austenitic Stainless Steel Pipe, 6Mo Alloy Pipe) is a high‑molybdenum (6.0‑7.0%) super austenitic stainless steel offering exceptional resistance to chloride‑induced pitting, crevice corrosion, and stress corrosion cracking. It conforms to ASTM B677 (seamless pipe), ASTM B673 (tube), ASTM B674 (welded pipe), and ASME SB677, with designation UNS N08926 and EN 1.4529. This high chloride resistant pipe combines the strength of austenitic stainless steel with the corrosion resistance of nickel alloys, making it ideal for seawater systems, desalination plants, FGD systems, and offshore platforms.

Key properties of Incoloy 926:

• Exceptional chloride resistance – PREN (Pitting Resistance Equivalent Number) > 43, providing outstanding protection against pitting and crevice corrosion in high‑chloride environments

• Superior seawater corrosion resistance – immune to biofouling and galvanic attack in warm, stagnant, or flowing seawater

• Stress corrosion cracking resistance – no chloride‑induced SCC, even in marine atmospheres and sour service

• Molybdenum enriched stainless steel – 6‑7% Mo content ensures robust passivity under reducing and oxidizing conditions

• High PREN alloy material – outperforms duplex (2205) and many nickel alloys in mixed acid/chloride service

• Good weldability – retains corrosion resistance in as‑welded condition with matching filler metal

Note: Incoloy 926 is a cost‑effective alternative to nickel alloys like Alloy 625 in many seawater and brine applications. It is not recommended for high temperature reducing acids (use Hastelloy).

This corrosion resistant process pipe is available in seamless (ASTM B677) and welded (ASTM B674) forms, cold drawn, hot finished, pickled, or polished. We offer custom sizes, cut to length, large diameter, and thin wall options, with Schedule 40 and Schedule 80 schedules. Our product range includes Incoloy 926 seamless pipe, welded pipe, large diameter pipe, custom size, and cut to length pipe.

Applications 

1. Seawater Systems & Desalination Plants

• Incoloy 926 pipe for seawater systems – seawater intake lines, cooling water piping, firewater mains, and ballast lines on ships, platforms, and coastal power plants. Superior seawater corrosion resistance eliminates need for coatings, cathodic protection, or frequent replacement.

• Incoloy 926 pipe for desalination plants – high‑pressure brine feed lines, recirculation loops, and interconnecting piping in reverse osmosis (RO) and multi‑stage flash (MSF) plants. Chloride resistant alloy pipe withstands warm, concentrated brine without pitting.

• Brine handling systems – piping for sodium chloride, potassium chloride, and magnesium chloride solutions in chemical and mining applications.

2. Offshore Platforms & Marine Engineering

• Incoloy 926 pipe for offshore platforms – topside process piping, hydraulic control lines, and instrument air tubing in North Sea, Gulf of Mexico, and Southeast Asian fields. Pitting resistant alloy performs under splash zone and submerged conditions.

• Incoloy 926 pipe for marine engineering – shipboard seawater cooling loops, desuperheater lines, and ballast system piping. Crevice corrosion resistant pipe prevents under‑gasket and under‑deposit attack.

3. Flue Gas Desulfurization (FGD) Systems

• Incoloy 926 pipe for flue gas desulfurization systems – absorber tower spray headers, recirculation piping, and oxidizer air spargers in coal‑fired power plants. Molybdenum enriched stainless steel handles low‑pH, high‑chloride scrubber liquor at temperatures up to 80°C.

• FGD system pipe supplier – also used in quench nozzles, duct transition pieces, and slurry recirculation lines. High PREN alloy material resists erosion‑corrosion.

4. Oil & Gas / Chemical Processing / Heat Exchangers

• Incoloy 926 pipe for oil and gas industry – topside chemical injection lines, subsea control tubing, and wellhead flowlines (sweet service). Stress corrosion cracking resistance ensures safety in wet CO₂ and low‑H₂S environments.

• Incoloy 926 pipe for chemical processing – piping for phosphoric acid, sulfuric acid (dilute, at ambient temperatures), and mixed acid waste streams. Corrosion resistant offshore alloy outperforms 316L and duplex.

• Incoloy 926 pipe for heat exchangers – tube bundles and shells for seawater‑cooled exchangers, brine heaters, and condenser systems. High strength super austenitic stainless steel allows thinner walls and better heat transfer.

5. Pulp & Paper Industry / Industrial Brine Applications

• Incoloy 926 pipe for pulp and paper industry – bleach plant piping (chlorine dioxide, hypochlorite), green liquor lines, and liquor heaters. Chloride resistant pipe resists aggressive bleaching chemicals.

• Incoloy 926 pipe for chemical processing – also used in phosphoric acid evaporators, chloride‑containing organic synthesis, and textile bleaching equipment.
