egeplast high-pressure pipe passes a high-pressure test of 50 bar on the test bed
The new egeplast HexelOne pipe makes possible both high-pressure applications as well as a reduced usage of material in familiar applications. The reason: As compared to the existing polyethylene pipes, it has about double the strength.
