PE100 Flange with Bolt Hole: Specifications, Applications, and Custom Manufacturing

PE100 Flange with Bolt Hole: Specifications, Applications, and Custom Manufacturing

A PE100 flange with bolt hole is a critical connection component used in HDPE piping systems to connect polyethylene pipes with valves, pumps, steel pipes, or other flanged equipment. The bolt holes on the flange allow secure mechanical fastening using bolts and gaskets, ensuring a reliable and leak-free connection.

Due to its excellent mechanical strength and corrosion resistance, PE100 HDPE flanges with bolt holes are widely used in water supply, wastewater treatment, industrial, and mining pipeline systems.

What Is a PE100 Flange with Bolt Hole?

A PE100 flange with bolt hole is manufactured from PE100-grade high-density polyethylene material. The flange face contains evenly distributed bolt holes designed according to international flange standards, allowing it to be bolted to a matching metal or HDPE flange.

This type of flange is commonly used together with:

• HDPE stub ends

• Flange adapters

• Steel or ductile iron flanges

The bolt hole design ensures strong axial connection strength while maintaining the flexibility advantages of HDPE piping systems.
