How to Distinguish Between High-Quality and Poor-Quality PPR Pipes?

A single quick inspection can tell you whether a ppr plastic material pipe will last 50–100 years or fail in less than 10. High-quality certified PPR feels smooth, smells neutral, cuts cleanly, and carries permanent printing every meter — while poor-quality recycled or mislabeled pipe looks dull, smells chemical, feels brittle, and often lacks proper […]

What Are the Standard Inner and Outer Dimensions of PPR Pipes?

Knowledge / By IFAN

Every certified ppr pipe material follows the exact same international dimension standard (EN ISO 15874 / DIN 8077/8078), so a 25 mm PPR pipe from any reputable factory has identical outer diameter and wall thickness whether you buy in Europe, Asia, or the USA. This complete guide gives you ready-to-use dimension tables for PN16, PN20,

Which Color of PPR Pipe (Green, White, Gray) Is Better in Quality?

Knowledge / By IFAN

The color of a ppr pipe for water supply — green, white, or gray — has absolutely nothing to do with the actual quality or strength of the pipe itself. All three colors come from the exact same virgin polypropylene random copolymer (PP-R) raw material when made by reputable factories. The only difference is a
