Flange (Solid Style), FPT PVC Schedule 80 1-1/2" (852-015)

The 852-015 is a 1-1/2" PVC Schedule 80 solid style flange with a female pipe thread (FPT) inlet, designed to create a bolted flange connection at the end of a threaded PVC pipeline. The FPT inlet accepts any standard 1-1/2" NPT male-threaded pipe or fitting, while the flat face flange plate bolts directly to any mating 1-1/2" ANSI/ASME B16.5 Class 150 flange — including companion flanges, valve flanges, pump flanges, and equipment nozzles — using a flat face gasket and standard bolt pattern.

Manufactured from rigid, dark gray PVC compound conforming to ASTM D1784 cell classification requirements, the Schedule 80 solid style flange is produced from heavier-wall stock than Schedule 40 equivalents, providing the additional mechanical strength required to withstand bolt-up clamping forces, line pressure, and thermal cycling in demanding industrial and chemical service environments. The solid (non-van stone) flange body is a single molded piece — the flange face and hub are permanently integrated, eliminating the slip-on backing ring required by van stone style flanges and simplifying installation where a one-piece assembly is preferred or specified.

The all-PVC construction provides excellent resistance to a broad range of corrosive media including acids, caustics, chlorinated water, and many industrial process fluids, making the 852-015 a practical alternative to stainless steel or other corrosion-resistant metal flanges in chemical, water treatment, and municipal applications. At 1-1/2", this flange is commonly found at pump suction and discharge connections, chemical dosing system tie-ins, and filter vessel nozzles where a mid-range pipe size must transition to a bolted flanged joint. The FPT inlet provides rotational alignment flexibility during assembly before final bolting, a meaningful practical advantage in tight mechanical spaces where pipe alignment can be challenging.

Industries & Applications:

• Chemical Processing — Bolted flange connections at pump suction and discharge nozzles, vessel tie-ins, and chemical feed equipment in corrosive service environments where all-PVC construction eliminates metal corrosion and galvanic compatibility concerns
• Municipal Water & Wastewater — Pump station and treatment facility piping where 1-1/2" flanged connections are required at pump flanges, valve flanges, and equipment nozzles for serviceability and alignment
• Industrial Process Piping — Flanged terminations in cooling water, process fluid, and recirculation systems at the 1-1/2" pipe size requiring robust Schedule 80 construction and bolted joint integrity
• Water Treatment & Filtration — Flanged connections at filter vessels, chemical dosing equipment, and membrane housings in potable water and industrial water treatment systems
• Irrigation & Agriculture — Flanged tie-ins at pump discharge, filter stations, and control valve assemblies in pressurized irrigation systems where a serviceable bolted connection is required
• HVAC & Mechanical — Flanged connections at chiller and cooling tower piping tie-ins where PVC is specified for corrosion resistance and the bolted joint must remain accessible for future maintenance or equipment replacement
