NACE (National Association of Corrosion Engineers) standards are crucial for ensuring corrosion resistance in piping systems, particularly in industries where the risk of corrosion is high, such as oil and gas, chemical processing, and water treatment. These standards provide comprehensive guidelines for controlling both external and internal corrosion, ensuring the longevity and safety of piping systems. Riyaarth Overseas offers piping solutions that comply with NACE standards, providing reliable and durable products for demanding applications.
Key Features of NACE Standards for Corrosion Resistance
Comprehensive Guidelines:
- NACE standards cover procedures for controlling external corrosion on buried or submerged metallic piping systems using methods like coatings and cathodic protection.
- Internal corrosion control in steel pipelines transporting crude oil, refined products, and gas will also be addressed.
Industry-Specific Solutions:
- Standards such as NACE MR0175/ISO 15156 focus on material selection to prevent environmental cracking caused by hydrogen sulfide.
- Ensure that all components in contact with process fluids meet NACE requirements to prevent material failure.
Versatile Applications:
- Widely used in oil and gas transmission, chemical processing, and water treatment industries where corrosion resistance is critical.
- Ensure that piping systems are designed to handle corrosive environments effectively.

Manufacturing Process
Pipes manufactured under NACE standards undergo rigorous processes to ensure compliance:
- Material Selection: High-quality materials are chosen based on specific NACE requirements for corrosion resistance.
- Coating Application: External coatings are applied to prevent corrosion, often supplemented with cathodic protection.
- Cathodic Protection Systems: Designed and installed to protect buried or submerged pipes from external corrosion.
- Inspection Protocols: Regular inspections using techniques like ultrasonic testing or corrosion coupons to monitor corrosion levels.
- Maintenance Practices: Include regular cleaning and monitoring of internal corrosion conditions.
Common Applications
Oil & Gas Industry:
- Used in pipelines for transporting crude oil, natural gas, and refined products where corrosion resistance is critical.
- NACE standards ensure that piping systems are designed to handle corrosive substances and environments effectively.
Chemical Processing:
- Essential for handling corrosive chemicals in reactors and transfer lines by selecting materials that resist chemical reactions.
- NACE standards guide the use of corrosion-resistant alloys to prevent material failure.
Water Treatment:
- Used in water supply systems to prevent corrosion and ensure the purity of water by selecting appropriate materials and coatings.
- NACE standards help maintain the integrity of piping systems in harsh environments.
Available Sizes and Dimensions
NACE-compliant pipes are available in a wide range of sizes:
Pipe Size (NPS) | Wall Thickness (Sch STD) | Wall Thickness (Sch XS) |
1/2″ | 0.083″ | 0.109″ |

Testing and Quality Standards
To ensure reliability in critical applications:
- Hydrostatic Testing: Verifies pressure-handling capabilities.
- Non-Destructive Testing (NDT): Includes ultrasonic or radiographic inspections.
- Chemical Analysis: Confirms material composition compliance.
- Corrosion Monitoring: Regular inspections using corrosion coupons or probes.
Surface Finish and Coatings
To enhance durability:
- Standard finishes include epoxy or polyethylene coatings.
- Additional coatings such as fusion-bonded epoxy (FBE) or three-layer polyethylene (3LPE) provide enhanced corrosion resistance.
Environmental Considerations
NACE standards also address environmental concerns by promoting sustainable practices:
- Material Efficiency: Encourages the use of materials that minimize waste and reduce environmental impact.
- Safety Protocols: Ensures that piping systems are designed to prevent leaks and spills, protecting ecosystems.
