PPH Pipe Fittings – Elbow, Tee, Flange, End Cap & Union
PPH Pipe Fittings are designed for industrial thermoplastic piping systems where reliable corrosion resistance, secure connections and long-term operating performance are required. Manufactured from Polypropylene Homopolymer (PPH), this fitting range is suitable for chemical processing plants, industrial process piping, corrosive medium transportation and other demanding piping applications.
The product range covers commonly used PPH fittings for pipeline connection, direction changes, branch connections, sealing and equipment integration. Depending on the fitting type, available sizes range from DN15 to DN355, with PN10 and PN16 pressure configurations available for applicable products. Both socket fusion and butt fusion connection methods are provided to accommodate different pipeline diameters and installation requirements.
PPH Pipe Fittings Product Range
| Product | Core Parameters & Application |
|---|---|
| PPH Integral Flange | One-piece injection molded socket fusion integral flange, DN15-DN110, PN10/PN16. Designed for flange connections between PPH pipelines and valves, pumps and other equipment. The integrated structure eliminates assembly gaps and helps reduce leakage risks associated with loose sleeve flange connections. |
| PPH 90° Elbow (Socket Fusion) | Socket fusion 90° elbow, DN15-DN110, PN10/PN16. Features a standardized socket depth for reliable hot melt welding and uniform wall thickness to help reduce fluid pressure loss. Suitable for medium and small diameter industrial pipeline direction changes. |
| PPH End Cap | Socket fusion pipe end cap, DN15-DN110, PN10/PN16. Manufactured with full wall thickness for reliable pressure resistance. Used for temporary or permanent sealing of pipeline ends to help prevent medium leakage. |
| PPH 45° Elbow (Socket Fusion) | Socket fusion 45° elbow, DN15-DN110, PN10/PN16. Provides a smoother direction change and lower flow resistance than a 90° elbow, making it suitable for process pipelines requiring reduced pressure drop and smooth fluid transmission. |
| PPH 90° Elbow (Butt Fusion) | Butt fusion 90° elbow, DN20-DN355, PN10/PN16. Butt fusion creates a homogeneous welded joint with full penetration. Suitable for large-diameter outdoor main process pipelines used for corrosive-medium transportation in chemical plants. |
| PPH Equal Cross (Socket Fusion) | Socket fusion equal diameter cross, DN15-DN110, PN10/PN16. Provides four-way equal-diameter branching with standardized socket interfaces, simplifying multi-branch node design in industrial pipeline networks. |
| PPH Equal Tee | Socket fusion equal diameter tee, DN15-DN110, PN10/PN16. Designed with an optimized internal transition structure to help reduce turbulence and erosion caused by corrosive fluids, improving the long-term reliability of branch connections. |
| PPH Female Threaded Socket (Socket Fusion) | Socket fusion female threaded socket, DN15 1/2″-DN100 4″, PN10. One end is socket fused to PPH pipe while the other end provides an internal threaded connection for metal valves, instruments and equipment. Suitable for transitions between thermoplastic fusion piping and threaded metal components. |
| PPH Union (Socket Fusion) | Socket fusion union, DN15-DN110, PN10/PN16. Features a quick-disassembly design that allows pipe sections, instruments and valves to be maintained without cutting the pipeline. Suitable for modular industrial piping systems. |
Socket Fusion and Butt Fusion Connections
PPH Pipe Fittings are available with socket fusion and butt fusion configurations according to the fitting type and pipe diameter. Socket fusion fittings are commonly used for smaller and medium diameter piping systems, providing compact and reliable welded connections. Butt fusion fittings are suitable for larger diameter pipelines and create a continuous homogeneous joint between the pipe and fitting.
The appropriate connection method should be selected according to pipe size, fitting configuration, operating conditions and the requirements of the complete piping system.
Industrial Applications
PPH Pipe Fittings are suitable for a wide range of industrial applications where corrosion resistance and reliable thermoplastic piping connections are important. Typical applications include:
- Chemical processing plants
- Chemical production facilities
- Industrial process piping
- Corrosive chemical transportation
- Wastewater and industrial water treatment systems
- Chemical storage and transfer systems
- Outdoor process pipelines
- Industrial equipment connection systems
- Modular thermoplastic piping networks
The combination of PPH material and fusion-welded connections provides an integrated piping solution for applications involving corrosive media and demanding industrial environments.
