Bellows equipment: Perfect online double-layer expansion technology!

How are double walled corrugated pipes connected. Many people have this confusion: how does it connect?

The most suitable connection method for double wall corrugated pipes is the flared connection.

Those who have seen this type of pipe will find that its two ends are different, one is a flared structure, and the other is a small end structure. Through this structure, two pipes can be perfectly inserted together, with one end of the expansion facing upstream of the drainage and the small end facing downstream of the drainage, ensuring a safer connection without leakage.

Nowadays, many corrugated pipe brands can provide online double-layer expansion technology, but when you cut the socket into pieces, you will find that most of them are unqualified, especially if the two layers cannot fully fit, which poses a great risk.

And the sockets of our product perfectly fit the two layers from beginning to end. For different sockets, you can easily see the differences. Imagine what would happen if you buried unqualified corrugated pipes underground.

In addition to appearance, more consideration is now being given to online double layer sockets to provide the best corrugated pipe solution!
