3 Inch Schedule 80 PVC Pipe (3.5 OD / 2.9 ID) – 18 Inches
Dimensions: 3.5″ outer diameter, 2.9″ inner diameter. This Schedule 80 pipe features enhanced wall thickness designed for higher pressure ratings compared to Schedule 40. The stated maximum working pressure is 370 PSI, making it suitable for demanding industrial plumbing systems and high-pressure applications. Use solvent-w Weld fittings for secure, leak-resistant connections in pressurized lines. Ideal for environments where strength, reliability, and chemical resistance are essential.
3 Inch Schedule 80 PVC Pipe – 36 Inches
Dimensions: 3.5″ OD / 2.9″ ID. Enhanced wall thickness offers higher pressure ratings than Schedule 40, up to 370 PSI maximum working pressure. This pipe supports industrial plumbing networks and other high-pressure installations where robust durability is required. The 36″ length provides a flexible option for longer runs without frequent connections, aiding in reducing potential leak points.
PVC Pipe Schedule 80 Grey 3″ Diameter – 5 Ft
Heavy-duty Schedule 80 construction provides thicker walls for superior strength and durability in high-pressure applications. Plain-end design allows easy cutting and solvent-weld fittings for secure, watertight connections. Suitable for plumbing, irrigation, and industrial uses that require reliable performance and long service life.
PVC Pipe Schedule 80 Grey 3″ Diameter – 3 Ft
Thicker Schedule 80 walls provide enhanced strength for high-pressure pipelines. Plain-end design facilitates straightforward cutting and solvent-weld connections for a dependable seal. Suitable for domestic, commercial, and industrial applications where consistent performance matters.
3″ Steel Pipe Nipple – Schedule 80 (3″ x 8″)
Made in the USA, this seamless steel pipe nipple is threaded on both ends and suited for rigid, high-pressure plumbing assemblies where metal-to-metal connections are preferred or required. Schedule 80 steel provides robust resistance to mechanical stress and corrosion in compatible environments, making it a viable complement to PVC systems in mixed-material configurations.
Spears 829 Series PVC Fitting – 3″ Socket Coupling
Coupling designed to connect two pipes of the same diameter in a straight run. Socket ends accommodate male fittings, and the PVC material delivers chemical and corrosion resistance while remaining lighter than metal alternatives. This fitting supports efficient, leak-resistant joins in high-pressure piping networks and is compatible with Schedule 80 systems.
ERA Schedule 80 PVC Coupling – 3 Inch
829 Series heavy-duty PVC coupling designed for Schedule 80 systems, offering strong pressure resistance and long-term durability. Socket connections support solvent-weld installation for tight, leak-resistant joints in industrial piping. Suitable for high-pressure water and chemical handling where reliability is essential.
PVC Pipe Schedule 80 Grey 3″ Diameter – 2 Ft
Thick-walled Schedule 80 PVC pipe with plain ends supports efficient cutting and solvent-weld connections. Its multi-use design fits plumbing, irrigation, industrial, and commercial applications requiring durable, high-pressure performance and dependable long-term use.
Buying Guide: Key Considerations For Choosing 3-Inch Schedule 80 Pipe And Fittings
- Pressure rating and temperature: Schedule 80 pipes offer higher pressure ratings than Schedule 40. Verify maximum working pressure (and allowable temperature) for your system to ensure safe operation under real conditions.
- Material compatibility: PVC Schedule 80 is chemical resistant and lighter than metal alternatives, but ensure compatibility with the fluids in use. For aggressive chemicals, verify compatibility with fittings, couplings, and seals.
- Wall thickness and strength: Schedule 80 features thicker walls, which support higher mechanical loads and reduce risks of deformation under pressure, making it suitable for industrial environments.
- Connection method: Plain-end vs. solvent-weld cuffs; solvent-weld joints provide watertight seals but require proper surface preparation and curing time. Socket fittings simplify assembly but require compatible components.
- Length and routing: Plan runs to minimize joints in high-pressure lines. Longer continuous runs reduce leak points but require careful handling and support.
- Code and compatibility: Ensure the selected components meet local plumbing and building codes for the intended application, especially in commercial or industrial facilities.
- Installation environment: Consider exposure to UV, temperature swings, and potential impact. Schedule 80 components are durable but should be protected when used outdoors or in harsh settings.
- System integration: For mixed-material systems (PVC with metal nipples or adapters), choose compatible connectors and ensure proper sealing methods to prevent galvanic corrosion or leaks.
