PEXGOL pipes comply with the applicable standard requirements of the international markets. The production and quality plans are periodically surveyed by representatives of the various standard institutes. The regulations and applicable standards are the basis for monitoring the products in accordance with the controlled standards. PEXGOL pipes have been tested and approved for use in potable water systems and piping systems for gas, chemicals and abrasive materials by several international testing laboratories and institutes (DVGW, NSF, AENOR and others).
Pipes designated for heating applications are coated with a protective barrier layer that reduces oxygen permeability, according to DIN 4726 requirements.
Quality Control tests are carried out during all stages of the production process, from the raw materials and the fittings, through the production to the final tests of the finished products before packing and delivery.
