Flange (Solid Style), FPT PVC Schedule 80 3" (852-030)

The 3" PVC Schedule 80 Solid Style Flange (Part No. 852-030) is a pressure-rated, gray-body flange fitting that combines a fixed, one-piece flanged face with a female pipe thread (FPT) connection to provide a bolted, demountable joint on threaded PVC piping systems. As a solid style flange, the ring and hub are molded as a single integrated unit — as opposed to a loose ring flange where the outer ring rotates freely — giving the assembly a rigid, structurally unified profile that is well-suited to permanent installations where pipe rotation during assembly is not a concern.

The FPT (female pipe thread) connection accepts a male-threaded pipe end or fitting, making this flange the correct choice where the piping system terminates in a threaded configuration or where a solvent-cemented slip connection is not practical. Threaded flanges are commonly used for equipment connections, valve tie-ins, and system interfaces where field adjustability or periodic disconnection on the threaded side is an operational preference.

The flanged face mates to any standard ANSI/ASME B16.5 Class 150 mating flange — including those on pumps, valves, strainers, meters, and process equipment — creating a bolted joint that is fully demountable for maintenance, inspection, and component replacement without disturbing the upstream threaded pipe connection. A flat face gasket between flanged faces completes the seal.

At 3", this fitting is a common specification in mid-scale industrial loops, commercial mechanical rooms, and municipal systems where a threaded entry point into a flanged connection is required. Manufactured from Type I, Grade I PVC compound and conforming to ASTM D2467 dimensional standards, this fitting delivers the wall thickness and pressure ratings that define Schedule 80 over Schedule 40.

Industries & Applications:

• Industrial & Chemical Processing — Threaded equipment tie-ins and pump connections on chemical-resistant PVC systems where a bolted flanged interface is required at the equipment face
• Municipal Water & Wastewater — Flanged connections to valves, meters, and treatment equipment on 3" mains where a threaded pipe entry is present
• Commercial Plumbing — Mechanical room equipment connections and system access points on threaded Schedule 80 infrastructure requiring a standard flanged interface
• Irrigation — Pump station connections and mainline equipment interfaces on 3" threaded PVC systems requiring a bolted flanged joint
• Mining & Oil Field — Corrosive fluid handling systems requiring a durable, chemical-resistant flanged connection at threaded equipment interfaces
• Power Generation & Utilities — Cooling water and process fluid systems where a threaded PVC entry to a flanged connection provides corrosion resistance at equipment tie-ins
• Aquaculture & Water Treatment — Filter housing, pump, and dosing equipment connections requiring a serviceable flanged joint on threaded PVC systems
