To protect the pipe from burining, a cooling system is part of the oven to. Gaseous reaction products are instantly removed by an integrated extraction system which aspirates them di- rectly from the oven and all neighboring line parts. Intelligent cooling system In order to protect the pipe from overheating during the cross-linking proces, an air cooling system has been integrated. This is an intelligent cooling system which protects the pipe from burning and ensures the safe handling of the pipe material. This specific PEXa process stands for the complete cross-linking inside the pipe wall as the pipe is per- fectly cross-linked „in a hot state“, i.e. above the melt temperature. Due to the high cross-linking degree, the required long-term pipe properties, namely a very high flexibility and ease of installation are achieved already with small wall thickness sizes. PEXLINK technology stands for a long-term temperature resistance and a proven lifespan of more than 50 years. PEXa pipes are permanently suitable for exposure to high (+95° C) and low (-60° C) temperatures and they are extremely pressure-resistant. Author: David Brinkmann, Marketing
