There are several PEX pipe manufacturers in China that produce high-quality PEX pipes for various applications. Haili pipe is one of the best PEX pipe manufacturers in China.

PEX pipe, short for cross-linked polyethylene pipe, is a type of plastic pipe that is widely used in plumbing, heating, and other water distribution systems. It is known for its flexibility, durability, and ease of installation.

PEX pipe is made by cross-linking polyethylene molecules, which enhances its properties and allows it to withstand high temperatures and pressures. The cross-linking process improves the pipe's resistance to cracking, impact, and chemical degradation, making it suitable for a wide range of applications.

PEX pipe is available in different colors, typically red and blue, to distinguish between hot and cold water lines. It is commonly used in residential and commercial plumbing systems, radiant floor heating, hydronic heating, and other water distribution applications.

It's important to note that PEX pipe should be installed according to industry standards and local codes, and it is recommended to consult with professionals or experts for proper installation and usage guidelines specific to your application.
