Xieyu S.H Premium PPH Socket Fusion 90-Degree Elbows (S5 / 1.25MPa)

Redirect your industrial, chemical, and fluid-treatment pipelines securely with our premium Xieyu S.H PPH socket fusion 90-degree elbows, available at Atradesen.com. Manufactured by Xieyu (S.H / HIEH), a globally recognized leader in high-performance thermoplastic flow control, these heavy-duty PPH (Polypropylene Homopolymer) elbow joints are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperatures from -20°C to 100°C.

Featuring standard parallel socket depths and a heavy-duty, thickened wall profile, this professional 90-degree bend series is highly compatible with industrial chemical pipelines, acid pickling loops, electroplating lines, waste gas scrubbers, waste acid recovery, and wastewater treatment.

Precision Right-Angle Corners & Heavy-Duty Wall Profiles

In continuous process pipe manifolds, establishing a secure right-angle turn is vital for navigating tight industrial footprints. Our specialized 90-degree elbow features an exceptionally thick, heavy-duty wall profile that provides outstanding structural rigidity. The interior liquid path is designed to prevent fluid stagnant zones, maintaining a smooth flow with low frictional pressure drop. This minimizes long-term pipeline erosion and secures high water security around pipe transitions.

High-Integrity PPH Material Qualities

• Chemical & Abrasive Wear Resistance: Molded from high-purity Homopolymer Polypropylene, these S5-rated elbows 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 90-degree bends completely safe for drinking water pipelines, pharmaceutical loops, and food processing lines.
• Easy Molecular Fusion: The smooth, precision-machined internal socket ends are designed for hot-melt socket fusion welding, forming a unified, leak-proof molecular system.

⚠️ 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).
• Connection Methods: Requires standard socket fusion hot-melt welding connection. Ensure both pipe ends and internal sockets are cleaned and dried before heating to secure optimal molecular fusion. Alternatively, they can be welded using PPH plastic welding rods.

Frequently Asked Questions (FAQ)

Q: Why is PPH the preferred choice over standard PVC for industrial chemical pipelines?

A: PPH is composed of pure propylene monomers polymerized in a highly uniform linear crystalline structure. This molecular alignment delivers significantly higher chemical resistance, impact stiffness, and high-temperature stress-crack resistance compared to PVC, preventing deterioration in waste acid recovery loops up to 100°C.

Q: How do I weld these 90-degree PPH elbows to our existing pipe lines?

A: PPH pipes are permanently connected using thermal welding. For smaller sizes (20mm to 110mm), use a standard socket fusion hot-melt welding machine equipped with matching heating adapters to melt the pipe outer wall and the fitting inner socket together, forming a seamless molecular joint.
