At present, there are many brands of PP-R pipes on the market, and consumers can refer to the following methods to identify the advantages and disadvantages of various PP-R pipes:
A look: High-quality PP-R hoses are soft and oily. The inferior PP-R hoses are unnatural due to mixing with inferior plastic or even lime powder. The cut section is dry and oil-free. It feels like adding chalk dust.
Second touch: The inner and outer walls of the high-quality PP-R pipe are smooth, without uneven cracks, and the roughness of the inner and outer walls of the inferior PP-R pipe is concave and convex.
Sanken: The quality of PP-R pipes is heavier than inferior PP-R pipes. Most of the quality PP-R metal fittings are copper pieces with more than three waterproof seepage grooves (more than 50% copper content). VIII) Copper pieces are longer in size, thicker in thickness, and therefore heavier in weight than high quality PP-R fittings
Four-burning: High-quality PP-R raw material is a kind of hydrocarbon chain compound. Under the condition of flame temperature higher than 800 degrees Celsius, ideal combustion conditions and sufficient oxygen, only carbon dioxide and water vapor are released from combustion, and there should be no odor when burning. Residues, poor quality PP-R water pipes due to mixed with inferior plastic and other impurities, there will be odor when burning and residue consumers can cut from the PP-R pipe thin slice with a lighter to burn to identify.
