1. Not easy to leak, long life
Double-walled pipes are relatively hard, and are flexibly connected using natural rubber sealing rings. They are easy to install, have reliable connections, are not easy to leak, have low overall cost, and have a lifespan of up to 50 years.
2. Not easy to deform
The socket uses a double-layer pipe wall, which is expanded online during production and formed in one step, avoiding the easy deformation of the single-layer pipe wall due to the thin pipe wall.
3. Easy to install
The product is light in weight, easy to carry and connect, quick to construct, and simple to maintain.
