Product Description

Minimize turbulence and pressure drop with puhui HDPE 45 degree elbows. Injection-molded from premium PE100 resin, these socket fusion bends are rated for PN16 pressure. Designed for a smooth directional change in water supply and industrial fluid systems, our UV-resistant PE 45° elbows ensure a permanent, leak-proof molecular bond and exceptional chemical durability for a 50-year lifespan.

Applications

✅️Municipal Water Mains: Smooth direction changes in urban water networks.

✅️Industrial Process Lines: Handling corrosive chemicals and process water at high pressure.

✅️Mining & Slurry Transport: Reducing wear and tear in abrasive fluid systems.

✅️High-End Irrigation: Mainlines for large-scale agricultural and landscape projects.

Advantages

Socket Fusion 45 degree Elbow is a pipe fitting widely used in various pipe connections. Its application range is wide, including but not limited to water supply and drainage pipe systems. This connection method has its unique advantages, such as reliable quality and high construction efficiency, and with the advancement of technology, its application areas are constantly expanding, not only limited to gas pipeline systems, but also including pipeline systems with larger diameters.‌

Optimized Flow Dynamics: The 45-degree angle reduces “water hammer” effects and internal friction, making it the preferred choice for high-velocity pump discharge lines.
Molecular Fusion Joint: Utilizing socket heat fusion, the elbow and the pipe merge into a single, leak-proof unit that is stronger than the pipe itself.
Superior PE100 Durability: Offers higher environmental stress crack resistance (ESCR) and better pressure handling than traditional PE80 materials.
Zero Corrosion & Scaling: The mirror-smooth internal surface prevents sediment buildup and biological growth, ensuring clean fluid transport for decades.

Q&A

Q1: Why use a 45-degree elbow instead of a 90-degree elbow?
A: A 45-degree elbow provides a smoother path for fluid, resulting in less turbulence and a lower pressure drop. In systems where pump energy efficiency is critical, using two 45° elbows to create an offset is more efficient than a single 90° turn.

Q2: What is the heating time for PE socket fusion elbows?
A: Heating times depend on the diameter and wall thickness of the pipe. For example, a 20mm pipe typically requires 5 seconds of heating at 260°C, while a 63mm pipe may require 24 seconds. Always refer to our specific fusion chart for precision.

Q3: Can these 45° elbows be used for gas lines?
A: Yes, if they are manufactured and certified specifically for gas applications. Puhui offers specialized PE fittings for natural gas that meet strict safety standards. For standard water/industrial use, ensure you check the SDR rating.

Q4: Are PE100 fittings compatible with PE80 pipes?
A: Yes. PE100 fittings can be fused with PE80 pipes. In fact, using a PE100 fitting on a PE80 system often increases the safety factor at the joint due to the superior material properties of PE100.

Q5: How do I identify a socket fusion elbow?
A: A socket fusion elbow has a smooth internal socket that is slightly larger than the pipe’s outside diameter. It requires a heating tool (mirror) to melt both the pipe end and the internal socket before joining.
