Threaded Flange for Schedule 80 Pipe

This Zoro Select flange connects a 2-1/2 inch nominal pipe using a flanged by FNPT joint. The A105 steel body carries a black coating and meets Class 600 pressure ratings for industrial piping systems.

Thermals Noise and Power Draw in Normal Use

The fitting handles 1,450 psi maximum operating pressure at 72 degrees Fahrenheit and the same rating for steam service. It remains rated across a continuous temperature range from 80 to 780 degrees Fahrenheit without active cooling or power requirements.

Build Fit and Clearance

Eight bolt holes on a 5-7/8 inch bolt circle accept 3/4 inch diameter fasteners for secure mounting. The 7-1/2 inch outside diameter and 1-1/8 inch thickness define the envelope needed in the pipe run. The flanged by FNPT configuration mates directly with compatible threaded components.

Questions about this item

How do I install the Zoro Select 2-1/2" Class 600 threaded flange and what step is commonly missed?

Thread the flange onto Schedule 80 pipe using sealant rated for 780 Degrees F, then torque the eight 3/4 in bolts in a star pattern to the specified value; skipping the star sequence causes uneven gasket seating and leaks at 450 psi.

What maintenance or replacement will this A105 steel flange need over time?

Inspect the black coating and threads annually for corrosion or erosion from steam service up to 780 Degrees F; replace the flange if wall thickness falls below Schedule 80 minimum or if bolt holes elongate beyond 3/4 in.

What is the first limit reached under sustained high-temperature steam use?

The 450 psi maximum steam pressure rating at 780 Degrees F is the limiting factor; exceeding this pressure at temperature risks permanent deformation of the A105 material before any other failure mode appears.
