S.H PPH 45-Degree Socket Fusion Elbow | S5 1.25MPa Chemical-Grade Hot-Melt Pipe Bend Joint (20mm - 110mm) - Atradesen

Xieyu Premium PPH Socket Fusion 45-Degree Elbows (S5 / 1.25MPa)

Redirect your industrial, chemical, and fluid-treatment pipelines smoothly with our premium Xieyu PPH socket fusion 45-degree elbows, available at Atradesen.com. Manufactured by Xieyu (HIEH), a leading global developer of industrial plastic flow systems, these heavy-duty PPH (Polypropylene Homopolymer) fittings are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperature loads from -20°C to 100°C.

Featuring a thickened wall profile and standard parallel socket depths, this professional 45-degree bend series is highly compatible with industrial chemical pipelines, acid pickling loops, electroplating lines, waste gas scrubbers, waste acid recovery, and wastewater treatment.

Optimized 45-Degree Fluid Dynamics

In pressurized pipeline networks, routing fluids around tight 90-degree corners generates high turbulent resistance, pressure drops, and local cavitation wear. A 45-degree angle configuration provides a much gentler transition, stabilizing liquid velocity and protecting inline piping joints from water hammer shocks. This makes them highly suitable for power plant cooling lines, environmental protection ventilation, and large-scale food processing facilities.

High-Integrity PPH Material Qualities

• Chemical & Abrasive Wear Resistance: Molded from high-purity Homopolymer Polypropylene, these S5-rated fittings offer superior chemical resistance to highly corrosive media, organic solvents, strong alkalis, and mineral acids.
• Safe & Potable Certified: PPH is entirely non-toxic, lead-free, and odorless, making these elbows completely safe for drinking water pipelines, pharmaceutical loops, and food processing lines.

⚠️ Sizing & Socket Fusion Guidelines

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

• Double Female Socket Ends (ID): Both ends of this elbow are female sockets. Their inner diameters are designed to slide directly over standard pipes with outer diameters of: 20mm (DN15), 25mm (DN20), 32mm (DN25), 40mm (DN32), 50mm (DN40), 63mm (DN50), 75mm (DN65), 90mm (DN80), and 110mm (DN100).
• Weld Connection Methods: Requires standard hot-melt socket fusion welding using professional heating equipment to melt the joints together, securing a completely seamless, leak-proof molecular system. Alternatively, they can be welded using PPH plastic welding rods.

Frequently Asked Questions (FAQ)

Q: Why should I choose a 45-degree elbow over a standard 90-degree elbow in chemical pipelines?

A: A 45-degree angle reduces the direct frictional impact on the inside curve of the fitting. In chemical pickling loops or high-flow wastewater pipelines, media often contains abrasive sediments or suspended chemicals. A 45-degree elbow helps smooth the flow, reducing local wall erosion and significantly extending the lifespan of the entire piping network.

Q: Can standard PPR welding equipment be used to heat-weld these PPH elbows?

A: Yes. PPH and PPR share similar polypropylene base characteristics. Standard socket fusion hot-melt welding machines equipped with matching heating adaptors can weld PPH fittings. Ensure the welding temperature is adjusted precisely to PPH parameters (typically 260°C) and the pipe end is free of moisture and dirt before fusion.
