Ritable PEX-a (cross-linked polyethylene) pipes are made of high density polyethylene (HDPE) from LG chemical company. Our PE-Xa pipe has excellent chemical, corrosion, temperature and pressure resistance.Meanwhile it has achieved an average 84% of cross-linking degree during the manufacturing process, which is higher than the average degree in this sector. Ritable PE-Xa pipe has been exported to many countries and recognized by more and more user all over the world. With this technique the Ritable pipes could be made both in ISO 15875 and ASTM F876/877 standard.
