ASTM A182 F11 Class 2 self reinforced nozzle is manufactured from chromium molybdenum alloy steel forging and is designed for pressure vessels, heat exchangers, boilers, and high-temperature process equipment.
A self reinforced nozzle is an integral forged nozzle component that provides reinforcement through its forged geometry without requiring additional reinforcement pads around the opening. This design is commonly applied in pressure equipment where nozzle strength and connection reliability are required according to engineering design requirements.
Manufactured according to ASTM A182 / ASME SA182 specifications, F11 CL.2 nozzles are produced through forging, heat treatment, machining, and inspection processes.
Standard: ASTM A182 / ASME SA182
Material Grade: F11 Class 2
