What is upvc Tee 3″ GM ?
Specifications
The uPVC Tee 3″ SCH 40 complies with standards such as ASTM D2466 for injection-molded fittings and ASTM D1785 for pipe compatibility. Below are the key specifications:
| Parameter | Value/Details |
|---|---|
| Nominal Size | 3″ (all three ends) |
| Outside Diameter (OD) | 3.500″ (per ASTM D1785) |
| Wall Thickness (SCH 40) | 0.216″ |
| Pressure Rating | Up to 200 PSI at 73°F (23°C); derates with temperature (e.g., 100 PSI at 120°F/49°C) |
| Material | Type 1, Grade 1 uPVC (NSF-certified for potable water) |
| Joint Type | Solvent cement socket (interference fit, all three ends) |
| Dimensions (Approx.) | Center-to-end length: ~4.5–5 inches per socket; overall width: ~7–8 inches (varies by manufacturer, ±1/16″ tolerance) |
| Weight | 0.8–1.2 lbs (approximate) |
| Temperature Range | 32°F to 140°F (0°C to 60°C) maximum |
| Standards | ASTM D2466 (fittings), ASTM D1784 (material), NSF/ANSI 61 (potable water) |
These specifications ensure compatibility with uPVC SCH 40 pipes from manufacturers like Spears, Charlotte Pipe, or Ashirvad. The pressure rating is for water at ambient temperatures; consult manufacturer derating charts for higher temperatures.
Usage
The 3″ uPVC Tee is used in pressure piping systems to create a branch connection or merge flows. Common applications include:
- Water Supply and Distribution: Diverting water from a main line to branch lines in residential, commercial, or municipal systems.
- Irrigation Systems: Splitting water flow in agricultural drip or sprinkler setups.
- Industrial Piping: Handling non-flammable liquids like acids, bases, salts, or alcohols due to uPVC’s chemical resistance.
- Plumbing and HVAC: Creating junctions in potable water or cooling systems.
- Pool and Spa Systems: Directing water flow in filtration or circulation lines.
The fitting’s smooth interior minimizes friction loss, and its corrosion resistance prevents rust, scaling, or pitting, making it suitable for potable water (NSF/ANSI 61 certified) and harsh chemical environments. It is not suitable for compressed air, gases, or temperatures above 140°F.
Installation
The uPVC Tee is installed using solvent cement joints, requiring minimal tools (pipe cutter, primer, and cement). Follow these steps for a secure, leak-free connection:
- Preparation:
- Cut all three pipes square using a PVC pipe cutter or saw. Deburr and bevel edges with a file or chamfer tool to remove burrs.
- Dry-fit the tee and pipes to confirm alignment and insertion depth (typically ~3–4 inches per socket).
- Cleaning and Priming:
- Clean pipe ends and tee socket interiors with a dry cloth to remove dirt or moisture.
- Apply PVC primer (e.g., purple primer) to the pipe OD (at least 2/3 of insertion depth) and all three socket IDs using a dauber. Let primer dry for 10–15 seconds until tacky.
- Cement Application:
- Apply a thick, even layer of PVC solvent cement (medium-body for SCH 40) to the primed pipe ends.
- Quickly apply a thinner layer to the tee socket interiors.
- Insert each pipe into its respective socket with a 1/4-turn twist to spread cement evenly, pushing firmly until it bottoms out. Start with the main line (straight-through sockets), then the branch.
- Curing:
- Hold each joint under steady pressure for 15–30 seconds to prevent “push-out” during initial setting.
- Allow full cure time based on ambient temperature (e.g., 2 hours at 60–100°F; up to 24 hours below 40°F). Refer to the cement manufacturer’s cure schedule.
- Avoid pressurizing the system until fully cured.
- Testing:
- Pressure-test the system at 1.5x operating pressure for 2 hours, checking for leaks.
- Ensure compatibility with uPVC SCH 40 pipes; do not mix with CPVC or ABS.
