AAP blind flat face flange, 4"

This AAP blind flat face flange is made from steel to AS4087 PN21. It is supplied in 12 sizes from 4" (100mm) to 48" (1200mm). A blind flange has no centre bore. It closes off the end of a pipe run, a valve port or a vessel nozzle, and can be unbolted when you need access for inspection, cleaning or pressure testing. Plate flanges are mainly used for light duty, lower pressure or non-critical applications. They are cut and machined from plate steel.

Key specifications

Choosing the right option

Choose the blind flange that matches the standard, table or class and size of the flange it closes. Match the standard and table or class to the mating flange and compare the drilling dimensions, because flanges made to different standards are not interchangeable. Gaskets and bolting are not included. The 36" and 48" sizes are special manual orders because shipping costs vary.
