Bellmouth Pipes

What Are Bellmouth Pipes and Which Sizes Are Made?

Bellmouth pipes are U-PVC clean water pressure pipes with one widened, bell-shaped socket end, so they push into each other without adhesive. Düzgünler Plastik makes them in 17 sizes from Ø32 to Ø400, in PN 4, 6, 10 and 16 pressure classes, in grey.

This uPVC pressure pipe type is chosen for drinking water, infrastructure and irrigation lines where fast installation matters.

How Do Bellmouth Pipes Connect?

Short answer: the plain end of one pipe is pushed into the socket of the next. No adhesive and no curing time, so the line goes in fast.

• 1. Clean: No dust or sand on the pipe end or inside the socket.

• 2. Align: Keep both pipes on the same axis.

• 3. Push: Slide the plain end squarely into the socket.

What Are the Sizes and Wall Thicknesses?

The wall thicknesses below come from the official product table. Pipe length runs from 609 to 622 cm depending on size, so about 6 meters.
