Crosslinking process for PE-Xa pipe production

During the PE-Xa extrusion process, the PE-Xa pipe is fully cross-linked by inline infrared radiation. Since this process takes place before the tube enters the vacuum tank, subsequent reworking is not required. As the IR unit passes through the manufacturing process, the peroxide decomposes into reactive groups which split off hydrogen atoms from the polyethylene molecular chains. At the thus released binding sites, the molecular chains of the polyethylene crosslinked. The residence time in the IR oven, the radiation intensity of the IR emitters and the throughput speed of the tube are significant influencing factors. By integrating an air cooling system that adapts to the existing production rate, the pipe is protected from overheating during the curing process.
