The material selection for engineering pipes is undergoing drastic transformation. Factors including stricter environmental policies that raise entry barriers for small workshops, the rise of one-stop procurement models, and the rapid penetration of new materials (such as PE pipes) replacing traditional pipes have reshaped the industry landscape.

As concealed works buried inside walls or underground, pipes will require wall demolition and ground excavation once cracked or leaking. Many people only focus on pipe wall thickness when selecting pipes, assuming thicker pipes are better.
