Several experiments on testing the quality of PPR water pipes

High-quality water pipes with the same specifications have thicker pipe walls, more materials, and better thermal insulation and pressure resistance.

High-quality PPR water pipes will not smell when hot melted at high temperatures. As for inferior PPR water pipes, mixed with inferior plastic and other impurities, they will have odor and residue when burned. The inferior water pipes that produce this pungent smell will affect human health even more after long-term use. Therefore, it is recommended that when purchasing water pipes, you can cut thin slices from PPR water pipes and burn them with a lighter to identify them.

The inner wall of high-quality water pipes is smooth and flat without any bad concavities and convexities, which is not easy to break and is more environmentally friendly and healthy.

Since high-quality PPR metal pipe fittings use brass as raw material, the dosage is sufficient and the weight is light. Inferior PPR pipe fittings use nickel-plated copper fittings, which are made of low-quality materials and are light in weight. According to European drinking water standards, chromium and nickel plating of pipe fittings is not allowed. This will release metal elements harmful to the human body and cause secondary pollution of water.
