PP-R pipes by design require the most rigorous standards on the quality of raw materials. Internationally approved raw materials for PP-R pipes undergo long-term hydrostatic creep test, to ascertain their quality for certification.
Many manufacturers who are not quality conscious use recycled PP or non-conforming materials to make pipes and pass off as PP-R pipes. Priced conscious consumers may not be aware of what materials are used, as such they cannot distinguish between the authentic and counterfeit PP-R pipes thus buying inferior products from the market.
Therefore buying from trusted manufacturers or brand names can assure quality products.
VESBO® original imported products use 100% PP-R raw materials produced by European companies including SABIC, Borealis and Basell. Pipes of inferior quality are usually suspicious of using partial PP-R as raw materials.
