Alloy Steel Channel Cover Shell Side Flange SA336 F11 CL2

ALLOY STEEL CHANNEL COVER SHELL SIDE FLANGE ASME SA336 F11 CL.2

Material Specification: ASME SA336 F11 Cl.2

- SA336: ASTM/ASME standard for forged steel flanges, fittings, valves, and parts for high-temperature service.

- F11: Indicates Alloy Steel Grade F11, a chromium-molybdenum steel with good high-temperature strength and corrosion resistance.

- Class 2: Specifies the heat treatment condition (typically normalized and tempered for improved mechanical properties).

Application: Channel Cover (Shell Side Flange)

• Used in heat exchangers or pressure vessels as part of the shell-and-tube design.
• The channel cover seals the shell-side opening, allowing access for maintenance.

Design & Manufacturing Standards

Likely complies with ASME BPVC (Boiler & Pressure Vessel Code), Section VIII for pressure vessels.

Machined to match flange dimensions per ASME B16.5 (if standard) or custom design.

Key Considerations

1. Pressure & Temperature Rating: Must be selected based on service conditions.
2. Corrosion Resistance: Suitable for moderate corrosive environments (may require PWHT for weldments).
3. Dimensional Standards: Flange facing (RF, FF, RTJ) should match mating components.
