インチフランジ付きエクステンデッド

1. "Extended-length inch-dimensioned flanges serving as spacers in ASME B16.5 piping systems for component clearance." (96 chars)

2. "Elongated face-to-face flange with inch measurements, enabling extra installation space in pressure-rated pipe assemblies." (97 chars)

3. "Inch-based flanges with increased thickness/face distance, providing spacing in ANSI-classified industrial piping." (90 chars)

Key features covered:

•  Design: Extended length/thickness (vs. standard flange)

• Function: Creates spacer gap for valves, instruments, or clearance

•  Standard: Complies with ASME B16.5 / ANSI pressure classes

• Use: Critical in tight-layout industrial piping systems
