PE100 Flange with Bolt Hole – High Strength HDPE Flanged Connection Solution
In modern pressure piping systems, the PE100 Flange with Bolt Hole is an essential component for creating strong, detachable mechanical connections. As a type of high-performance PE100 flange, it allows HDPE pipelines to connect securely to valves, pumps, and steel flanged equipment.
Designed for durability and corrosion resistance, a HDPE flange with bolt hole ensures long-term sealing performance in demanding water, industrial, and irrigation applications.
What Is a PE100 Flange with Bolt Hole?
A PE100 Flange with Bolt Hole is manufactured from high-grade PE100 material and used together with a stub end and backing ring. The bolt holes are precisely drilled according to PN standards, allowing direct mechanical fastening to other flanged components.
This type of PE100 pipe flange is commonly used where system maintenance or equipment replacement may be required.
Key Features of PE100 Flange with Bolt Hole
1. High Pressure Resistance
The PE100 material provides superior strength, making the PE100 flanged fitting suitable for PN10, PN12.5, and PN16 systems.
2. Corrosion-Free Performance
Unlike metal flanges, a HDPE flange with bolt hole will not rust or scale, even in aggressive soil or water conditions.
3. Lightweight Design
A PE100 flange is significantly lighter than steel alternatives, reducing installation labor and transportation cost.
4. Long Service Life
Properly installed PE100 flanges can last over 50 years in water supply systems.
Structure of a PE100 Flanged Connection
A complete PE100 Flange with Bolt Hole assembly typically includes:
-
PE100 stub end (butt-fused to pipe)
-
Backing ring with bolt holes
-
Gasket
-
Bolts and nuts
The bolt holes allow even tightening, ensuring uniform sealing pressure across the flange face.
Applications of PE100 Flange with Bolt Hole
The PE100 Flange with Bolt Hole is widely used in:
-
Municipal water supply systems
-
Wastewater treatment plants
-
Industrial fluid pipelines
-
Irrigation networks
-
Mining slurry systems
-
Pump station installations
Because it forms a detachable joint, it is ideal for locations where valves or pumps require periodic maintenance.
Pressure Ratings and SDR Matching
When selecting a PE100 pipe flange, always match it with the pipe’s SDR:
-
SDR17 → PN10
-
SDR13.6 → PN12.5
-
SDR11 → PN16
Correct matching ensures the PE100 flanged fitting maintains full pressure integrity.
Installation Tips for PE100 Flange with Bolt Hole
To ensure long-term reliability:
-
Perform proper butt fusion on the stub end
-
Use compatible gaskets (e.g., EPDM)
-
Tighten bolts in a cross-pattern sequence
-
Avoid over-tightening
-
Ensure flange alignment before final torque
Correct installation guarantees that your HDPE flange with bolt hole performs safely under pressure.
Why Choose PE100 Flange Instead of Steel?
| Feature | PE100 Flange with Bolt Hole | Steel Flange |
|---|---|---|
| Corrosion Resistance | Excellent | Prone to rust |
| Weight | Lightweight | Heavy |
| Maintenance | Low | Higher |
| Service Life | 50+ Years | 20–30 Years |
For modern polyethylene piping systems, the PE100 Flange with Bolt Hole offers a reliable and cost-effective mechanical connection solution.
Conclusion
The PE100 Flange with Bolt Hole is a critical component in HDPE piping systems, providing high strength, corrosion resistance, and detachable connection capability. Whether used in water supply, irrigation, or industrial applications, a properly selected and installed PE100 pipe flange ensures long-lasting, leak-free performance.
