Chemical-Grade PPH Female Threaded Tees & 90-Degree Elbows (S5 / 1.25MPa)

Optimize and branch your industrial, chemical, and fluid-treatment pipelines with our premium PPH female-threaded tees and elbows, available at Atradesen.com. Molded from premium-grade, high-density PPH (Polypropylene Homopolymer), these chemical-grade fittings are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperatures ranging from -20°C to 100°C.

Designed to bridge solid pipelines directly with threaded instrumentation, water faucets, or liquid valves, this robust series is highly suitable for acid pickling loops, exhaust gas neutralization, and electroplating drainage networks.

Outstanding Chemical Stability & Material Resilience

PPH (Polypropylene Homopolymer) is widely preferred in heavy chemical processing and environmental protection fields due to its exceptional resistance to abrasive wear, high structural flexibility, and superior resistance to chemical corrosion from waste acids, alkalis, and organic solvents. It is also completely non-toxic and odorless, making these fittings fully safe for industrial drinking water networks, power plant cooling lines, and food processing lines.

Hot-Melt Socket Fusion & Reinforced Hex Collar Threads

These fittings feature a dual-connection mechanism optimized for maximum joint integrity:

• Smooth Socket Ends (Straight Run): Designed for standard hot-melt socket fusion welding to create a seamless, leak-proof molecular bond with standard PPH pipes. Alternatively, they can be securely welded using PPH plastic welding rods.
• Female-Threaded Port (90-Degree/Branch): Encased in a heavily thickened hexagonal outer collar. This added reinforcement prevents structural stress fractures and thread stripping when tightening standard G/BSP/PT male-threaded pressure gauges, sampling valves, or plumbing adapters.

⚠️ Sizing & Thread Compatibility Guide

The size specifications of this series represent: Socket Inner Diameter (ID) * Female Thread Size. Please check your nominal standards before selecting:

• 20mm x 1/2" (DN15): Socket ID fits 20mm outer diameter (OD) pipes; thread matches standard 1/2" male fittings. (Available in Tee & Elbow)
• 25mm x 3/4" (DN20): Socket ID fits 25mm outer diameter (OD) pipes; thread matches standard 3/4" male fittings. (Available in Tee & Elbow)
• 32mm x 1" (DN25): Socket ID fits 32mm outer diameter (OD) pipes; thread matches standard 1" male fittings. (Available in Tee & Elbow)
• 40mm x 1-1/4" (DN32): Socket ID fits 40mm outer diameter (OD) pipes; thread matches standard 1-1/4" male fittings. (Available in Elbow only)
• 50mm x 1-1/2" (DN40): Socket ID fits 50mm outer diameter (OD) pipes; thread matches standard 1-1/2" male fittings. (Available in Elbow only)
• 63mm x 2" (DN50): Socket ID fits 63mm outer diameter (OD) pipes; thread matches standard 2" male fittings. (Available in Elbow only)
• Note: Standard G/BSP/PT parallel threads. Always wrap additional PTFE thread seal tape (Teflon tape) clockwise around the male threads to secure a watertight, leak-proof mechanical joint.

Frequently Asked Questions (FAQ)

Q: Why is PPH preferred over standard PVC or PPR in acid pickling and exhaust gas recovery systems?

A: PPH (均聚聚丙烯) features a highly uniform crystalline structure. This delivers vastly superior chemical resistance and high-temperature stress-crack resistance compared to PVC. It won't degrade under strong exhaust vapors, industrial pickling acids, or waste acid regeneration loops up to 100°C, ensuring high security in chemical lines.

Q: Do these fittings require a specialized welding machine to install?

A: Yes. The smooth socket ends of the fittings require a standard socket fusion hot-melt welding machine to heat-weld onto PPH pipes. The threaded portion, however, is mechanical and simply screws onto matching standard G/BSP parallel male threads using Teflon tape.
