What Industries Commonly Use 2205 Stainless Steel Welded Pipes?
2205 stainless steel welded pipes are a cost-effective solution for industries that demand both superior corrosion resistance and high mechanical strength. As a duplex stainless steel alloy containing 22% chromium, 5% nickel, 3% molybdenum, and nitrogen, 2205 offers exceptional resistance to chloride-induced corrosion, pitting, and crevice attack, while providing strength far greater than conventional grades like 304 and 316.
At Ganyeah Group, we supply high-performance 2205 welded pipes designed to meet the critical requirements of global industries.
2205 duplex stainless steel welded pipes produced by Ganyeah Group
1. Oil and Gas Industry
The oil and gas sector is the primary application field for 2205 stainless steel welded pipes, where pipelines and equipment must withstand high chloride, H₂S, CO₂, and extreme pressures.
- Upstream: Offshore wellhead systems, subsea injection lines, and seawater injection pipelines.
- Midstream: Onshore and offshore gathering lines, gas and oil transmission pipelines, and refinery process piping.
- Downstream: Refinery desulfurization units, catalytic cracking piping, and LNG facilities where 2205 ensures superior low-temperature toughness.
2. Chemical and Petrochemical Industry
Chemical production involves harsh acidic and alkaline environments where corrosion resistance and strength are critical.
- Basic chemicals: Soda ash and caustic soda evaporator piping, phosphoric acid transport.
- Fine chemicals: Feed and discharge piping in pesticide and pharmaceutical reactors.
- Petrochemicals: Cooling water systems and polymer production lines for polyethylene and polypropylene.
3. Desalination and Marine Engineering
Seawater contains 3.5% chloride ions, creating one of the harshest environments for piping systems.
- Desalination plants: Reverse osmosis (RO) pretreatment pipelines, brine discharge systems, and multi-effect distillation heater tubes.
- Marine engineering: Cooling water systems on offshore platforms, ballast water pipelines, harbor facilities, and structural supports in coastal bridges.
4. Water Treatment Industry
2205 welded pipes ensure reliability in municipal and industrial wastewater treatment systems.
- Municipal plants: Aeration tanks, sludge transport pipelines, and reclaimed water distribution.
- Industrial treatment: Power plant cooling circuits, steel mill circulation lines, and zero-discharge wastewater systems in coal chemical facilities.
5. Pulp and Paper Industry
The pulp and paper sector uses aggressive bleaching agents like sodium hypochlorite and chlorine dioxide.
- Pulping: Piping in bleaching towers and washing systems.
- Papermaking: Wet section pipelines, recycled water systems, and effluent treatment lines.
6. Food and Beverage Industry
Food processing requires hygienic, corrosion-resistant piping that prevents contamination.
- Acidic products: Piping for tomato juice, vinegar, and pickling brines.
- Dairy and meat: Sterilization and cleaning systems resistant to disinfectants.
- Beverage: Brewing lines, beer filling equipment, and cleaning-in-place (CIP) systems.
Other Applications
- Energy: Nuclear plant cooling water lines, offshore wind turbine supports.
- Construction: Fire protection piping in humid basements, swimming pool circulation, and coastal curtain wall supports.
- Pharmaceuticals: Sterile production piping resistant to acid cleaning and steam sterilization.
The widespread adoption of 2205 stainless steel welded pipes is driven by their ability to combine strength, durability, and cost-efficiency in industries where 304 and 316 grades fall short. Whenever operations involve water, salt, or acidic environments, 2205 welded pipes provide long-term reliability and lower lifecycle costs.
