Cross-Linking Process Modifies Molecular Bonds

Producers use methods like peroxide (PEX-A), silane (PEX-B), or irradiation (PEX-C). Each method creates unique bonding structures.

Extrusion Process Forms Pipe Shape and Size

Melted polymer passes through a die. This process shapes the pipe into the desired diameter and thickness.

Cooling Phase Stabilizes Pipe Dimensions

After extrusion, the pipe passes through a cooling tank. This step locks the dimensions and prevents deformation.

Quality Control Verifies Wall Thickness and Pressure Resistance

Technicians use laser and pressure tests. These checks confirm the pipe meets safety and performance standards.

Final Coiling and Packaging Prepare Pipe for Shipping

Workers wind the pipe into large coils. Each coil receives protective wrapping for transport and storage.

Color and Marking Ensure Identification and Compliance

Manufacturers add color strips and printed labels. These marks show batch number, pressure rating, and pipe size.
