ASME B16.5 (up to 24”), ASME B16.47 (Series A/B over 26”). Material: ASTM A105 / ASME SA-105.
ASTM A105 is the most widely used standard specification for forged carbon steel piping components, including flanges, fittings, and valves, designed for ambient- and higher-temperature service in pressure systems. These components are essential in industries like oil and gas, petrochemicals, and power generation due to their high strength and durability. Material: Forged carbon steel (killed steel). Service Temp: −20°F to 800°F (−29°C to 427°C). CARBON STEEL ASTM A105 FLANGE
Used for small-bore, high-pressure piping. ASME B16
Excellent strength and toughness, high weldability, and good formability. These components are essential in industries like oil
Anti-rust oil, yellow passivation, or hot-dip galvanizing. To provide a more tailored report, could you specify:
Common in 150# to 2500# (Class 150-300 often "As Forged," higher classes usually normalized).
Normalizing is required for larger sizes or high-pressure classes (e.g., above 2 inch, Class 600+) to improve grain structure. Common Flange Types
