The PPH Female Thread Tee is a high-performance plastic fitting designed for creating branch connections in industrial piping systems. Made from Polypropylene Homopolymer (PPH), this tee offers exceptional chemical resistance, thermal stability, and ease of installation, making it an ideal choice for a wide range of applications.
Key Features and Benefits
- Superior Chemical Resistance
PPH Female Thread Tees are engineered to withstand aggressive chemicals, including strong acids (e.g., sulfuric acid, hydrochloric acid), alkalis (e.g., sodium hydroxide), and organic solvents. This makes them suitable for use in chemical processing, wastewater treatment, and other corrosive environments. - High-Temperature Performance
With a continuous operating temperature range of -20°C to 110°C (and short-term resistance up to 120°C), these tees are well-suited for hot water circulation, steam disinfection, and high-temperature chemical processes. - Lightweight and Durable
Weighing significantly less than metal fittings, PPH Female Thread Tees are easy to handle and install. Their extrusion-molded construction enhances molecular orientation, delivering excellent impact resistance and dimensional stability even at low temperatures. - Long Service Life
Designed for 50+ years of reliable service, these tees feature a smooth internal surface that minimizes scaling and reduces pressure drop, lowering energy consumption and maintenance costs. - Environmentally Friendly
Manufactured from 100% virgin PPH material, these fittings are non-toxic, odorless, and recyclable, complying with international standards like IRAM 13478 for potable water applications.
Technical Specifications
- Material: 100% virgin PPH (Polypropylene Homopolymer)
- Pressure Rating: Typically PN10 (1.0 MPa), suitable for low-to-medium pressure applications.
- Thread Type: BSP (British Standard Pipe Parallel Thread) for compatibility with global piping systems.
- Size Range: Common diameters from 1/2″ to 2″, with custom options available for larger projects.
- Certifications: ISO 9001:2008, WRAS (Water Regulations Advisory Scheme) approval for potable water use in the UK and EU.
Applications
PPH Female Thread Tees are widely used in:
- Chemical Industry: Connecting pipes in reactors, storage tanks, and scrubbers for transporting corrosive chemicals.
- Water Treatment: Branching pipelines in desalination plants, chlorination systems, and sewage treatment facilities.
- Agricultural Irrigation: Distributing water in drip and sprinkler systems, withstanding exposure to fertilizers and pesticides.
- HVAC & Thermal Systems: Diverting fluid flow in hot water heating loops and steam distribution networks.
Installation Guidelines
- Cutting the Pipe:
Measure and cut the pipe to the required length using a manual or machine cutter. Ensure the ends are perpendicular and smooth, and remove any burrs or sharp edges with a file. - Dry Fit and Marking:
Before applying adhesive, perform a dry fit to confirm the installation position and mark the insertion depth on the pipe. - Cleaning and Degreasing:
Clean the insertion end of the pipe (length = socket depth + 10mm) and the inner wall of the fitting socket with a cloth dampened in acetone. Allow the acetone to evaporate completely. - Adhesive Application:
Apply a thin, uniform layer of adhesive to both the pipe end and the fitting socket. Avoid applying too much adhesive to prevent excess from oozing out during insertion. - Assembly and Rotation:
Insert the pipe into the socket to the marked depth and rotate it slightly to ensure even distribution of the adhesive. Hold the assembly in place for 2–3 minutes to allow initial bonding. - Curing and Testing:
Avoid applying stress to the joint for at least 1 hour, and do not expose it to water for 24 hours to allow full curing. After curing, conduct a pressure test to verify the integrity of the connection.
