Key Product Advantages

• High Strength-to-Weight Ratio:​ The WPHY42 grade provides a minimum yield strength of 42 ksi [290 MPa], offering excellent mechanical properties for high-pressure applications while maintaining relatively light weight compared to higher-grade materials.
• Excellent Low-Temperature Toughness:​ Certified impact testing at -50°F [-46°C] ensures reliable performance in low-temperature environments, preventing brittle fracture in critical pipeline applications.
• Superior Weldability and Formability:​ The controlled chemical composition with maximum 0.42% carbon equivalent provides excellent weldability and formability characteristics, facilitating easy installation and field welding.
• Stringent Quality Assurance:​ All fittings undergo comprehensive testing including radiographic examination of welds, impact testing, and tension testing, ensuring material integrity and performance reliability.
• Full Compliance with Industry Standards:​ Manufactured in accordance with ASTM A860 requirements and compatible with ASME B16.9/MSS-SP-75 dimensional standards, ensuring interoperability and quality consistency.
