The types of household water pipes that are relatively common at present are: plastic-reinforced metal pipes-aluminum-plastic composite pipes, plastic pipes-PPR pipes, metal pipes-copper pipes, and metal pipes-copper pipes, among which the PPR pipe is most commonly used for its durable performance.
PPR tube purchasing skills:
one look
First look at the appearance, the appearance of high-quality pipe smooth, complete logo, accessories also have a brand name; inferior products can not do this. Because high-quality pipes use 100% imported PPR raw materials, and inferior pipes only use some PPR raw materials, the two have great differences in performance. The high-quality PPR pipes are bright and oily, and the poor quality PPR pipes are mixed with inferior plastic or even lime powder. The color is not natural, the cut section is dry and oil-free, and it feels like adding chalk dust.
Two touch
Toughness: Good PPR tube is good in toughness, can be easily bent into a circle without breaking, and inferior tube is more brittle and one bend is broken. The inner wall and outer wall of high-quality PPR pipes are smooth, with no concave-convex cracks, and the roughness of the inner wall of poor PPR pipes is concave and convex.
Sanhe
The quality of PPR pipes is heavier than that of poor PPR pipes. Due to the high quality of PPR metal fittings, most copper fittings with more than three waterproof seepage grooves (more than 58 percent copper) have a longer copper piece size. Thicker, and therefore heavier than inferior PPR fittings.
Four burning
The high-quality PPR raw material is a hydrocarbon chain compound. Under the flame temperature above 800 degrees Celsius, ideal combustion conditions and sufficient oxygen conditions, the combustion is only the release of carbon dioxide and water vapor, there should be no odor and residue when burning, poor quality PPR pipe Due to the mixing of inferior plastics and other impurities, there will be odors and residues when burning. Slices from PPR pipes can be identified by lighter burning.
In addition, good PPR pipes maintain their hardness at high water temperatures, while inferior pipes are softened at 60 degrees. Quality product warranty for 50 years, inferior products can only be 5-6 years.
