ASTM A234 Alloy Steel Pipe Fittings Oxidation Resistant For Power Plant
Alloy Steel Pipe Fittings For Power Plant Use
Specifications
Alloy Steel Pipe Fittings are engineered for demanding high-temperature and high-pressure applications where carbon steel fittings cannot meet performance requirements. Manufactured from chrome-molybdenum (Cr-Mo) alloy steel in accordance with ASME B16.9 (butt-weld) and ASME B16.11 (forged) standards, these fittings provide exceptional strength, oxidation resistance, and creep resistance at elevated temperatures.
Available in WP1, WP11, WP22, WP91, and other grades, alloy steel fittings are the standard choice for power generation, refinery, and petrochemical applications where operating temperatures exceed 400°C (750°F).
