Metal pipes might be abrasion-resistant, but metal is also brittle, and even though the pipe would withstand wear from the inside, it might be too brittle to handle stress from pressure surges or ground movements and would consequently break.

The Makknow HDPE pipe is designed to absorb this type of stress and offer optimal durability by combining the flexibility and corrosion resistance of polyethylene with an extremely wear-resistant inner layer. Also, instead of being hard, the inner polymer layer is soft since abrasion tests in laboratory as well as full-scale tests clearly indicate less wear for softer materials in most cases. This is how Makknow Pipe can prolong the life span of a piping system using functional polymer layers.
