The ASTM A860 WPHY42-80 Seamless Tees are high-yield wrought fittings designed for high-pressure transmission pipelines. While primarily high-strength carbon steel, they are engineered for "cryogenic" or low-temperature robustness through mandatory Charpy V-Notch testing (typically at -46℃). The Seamless construction provides maximum safety for high-stress gas and oil branches. These tees match the yield strengths of API 5L X42 to X80 line pipes, ensuring structural continuity in harsh environments.
