ASTM A860 WPHY 46 Pipe Fittings
ASTM A860 WPHY 46 is a high-strength carbon steel designed for use in high-pressure and high-temperature pipeline systems. With a minimum yield strength of 46,000 psi (317 MPa), WPHY 46 is ideal for demanding applications in the oil & gas, petrochemical, and power generation industries. It is well-suited for environments that require high durability, impact toughness, and excellent weldability.
Key Features:
- High Yield Strength: ASTM A860 WPHY 46 provides a minimum yield strength of 46,000 psi (317 MPa), making it perfect for high-pressure systems where strength is essential to ensure safety and durability.
- Weldability: WPHY 46 features excellent weldability, which ensures reliable and strong welded joints. This property is essential for creating long, continuous pipeline systems without sacrificing performance.
- Impact Toughness: The material maintains impact toughness even at low temperatures (down to -50°F / -45°C), ensuring structural integrity in harsh and cold environments.
- Corrosion Resistance: WPHY 46 offers moderate resistance to corrosion, making it suitable for marine, offshore, and subsea pipeline applications exposed to saltwater and other environmental factors.
- High-Temperature Strength: WPHY 46 is designed to withstand elevated temperatures, making it ideal for high-temperature steam lines and other applications where heat resistance is critical.
- Cost-Effective: As a carbon steel alloy, WPHY 46 offers a cost-effective solution for demanding pipeline applications, with a balance of strength, toughness, and affordability.
Applications:
- Oil & Gas: WPHY 46 is widely used in pipelines for crude oil, natural gas, and other hydrocarbons, both onshore and offshore.
- Petrochemical: It is used in petrochemical refineries and chemical process pipelines where pressure resistance and high strength are necessary.
- Power Generation: High-strength steam lines in power plants, where WPHY 46 helps maintain system efficiency under high-pressure and high-temperature conditions.
- Offshore & Marine: WPHY 46 is ideal for offshore pipelines that require resistance to both high-pressure and marine corrosion.
- Water Treatment: It is also suitable for water and wastewater treatment pipelines, where durability and mechanical strength are critical.
- Infrastructure: Large-scale construction projects involving reliable and strong pipeline systems benefit from the use of WPHY 46.
