Chemical-Grade PPH Butt Fusion Pipe Fittings & Valves | S5 1.25MPa Hot-Melt Weld Union, Flange, Tee, Elbow & Ball Valve (20mm - 110mm) - Atradesen

Chemical-Grade PPH Hot-Melt Fusion Pipe Fittings & True Union Ball Valves

Optimize and construct your high-performance industrial, chemical, and fluid-treatment pipelines with our premium PPH hot-melt fusion pipe fittings and valves, available at Atradesen.com. Crafted from heavy-duty, chemical-grade PPH (Polypropylene Homopolymer), these S5-rated fittings are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperature loads ranging from -20°C to 100°C.

Designed to be welded together into a single, integrated molecular piping system, this non-toxic and robust series is highly suitable for acid pickling loops, electroplating lines, exhaust gas recovery, wastewater treatment, and chemical processing networks.

Six Professional Symmetrical Configurations

Choose from our comprehensive array of fusion fittings and flow-control devices to layout your industrial pipeline run:

• 45-Degree Butt Fusion Elbow: Directs pipeline flow at a gentle 45-degree angle to reduce fluid turbulence and friction.
• Equal Tee Butt Fusion: Standard symmetrical 3-way branching splitter for dividing or merging pipeline flows.
• 90-Degree Elbow Butt Fusion: Changes pipeline direction smoothly by a standard 90-degree corner turn.
• Union Joint Butt Fusion: Symmetrical two-piece disconnect fitting allowing easy separation of pipe segments during maintenance.
• Double Union Ball Valve (True Union): Features a highly robust red handle. It permits complete block valve shut-off and allows inline disassembly of the valve body without cutting the main piping lines.
• Integrated Flange: One-piece flange plate with standard bolt alignment holes, perfect for transitioning from plastic piping to metal equipment nozzles.

⚠️ Sizing & Butt/Socket Fusion Guidelines

Nominal pipe dimensions are based on standard outer diameters. Please measure your pipe's outer diameter (OD) before placing your order:

• Thread-Free Fusion Ends: All ends are designed to connect to matching standard PPH pipes. The designated size (20mm to 110mm) corresponds to the outer diameter (OD) of the pipe.
• Weld Connection Methods: Requires standard hot-melt fusion (butt fusion or socket welding) using professional welding equipment to melt the joints together, securing a completely seamless, leak-proof molecular system.

Frequently Asked Questions (FAQ)

Q: What is the main operational benefit of a Double Union (True Union) Ball Valve?

A: In chemical piping networks, the ball valve may require cleaning due to crystallizing chemicals or debris. With a True Union design, you can simply unscrew the dual union nuts on both sides of the valve by hand. This lets you pull out the central valve body for cleaning or seal replacement without having to cut the welded pipes on either end.

Q: Is this PPH piping system compatible with strong acids and alkalis?

A: Yes. PPH Homopolymer offers superior crystalline density, making it exceptionally resistant to pickling acids, waste acids, alkaline wash solutions, and high-purity industrial effluents up to 100°C. It is widely preferred over PVC in tough industrial environments.
