I am a flange supplier, and my client sent me an inquiry. The product looks similar to the spacer specified in the ASME B16.48 standard, but the sizes in the standard only go up to 24 inches. I am wondering if there are other standards that provide larger sizes for spacers. Similar to how ASME B16.5 only includes flanges up to 24 inches, while ASME B16.47 covers blind flanges and WN flanges from 26 inches and above.
