Four strokes teach you to easily identify true and false PPR hose

The use of PPR pipes in home decoration is very high. The safety of water pipes is the precondition for the entire renovation. The high quality PPR pipes have long service life and high safety, and can save a lot of unnecessary troubles. However, there are many building materials markets. Poor quality, fake PPR water pipe shoddy, which requires consumers to polish their eyes to falsehood, the following Xiao Bian will teach you four strokes, so that you can easily identify the true and false PPR pipe.

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 PP-R pipes are light and oily, and inferior PP-R pipes are mixed into poor quality plastics. Even the lime powder has an unnatural color, 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 the high-quality PP-R pipe are smooth, without uneven cracks, and the roughness of the inner wall of the inferior PP-R pipe is concave and convex.

Sanhe

The quality of the PP-R pipe is heavier than that of the inferior PP-R pipe. Most of the quality PP-R pipe fittings have copper fittings with more than three waterproof seepage grooves (more than 58 percent copper). Copper pieces are longer in size and thicker in thickness, and therefore weigh more than inferior PP-R fittings.

Four burning

The high-quality PP-R raw material is a 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 the combustion, and there should be no odor and residue during combustion. PP-R water pipes have odors and residues when burned because they are mixed with inferior plastics and other impurities. Slices can be cut from PP-R water pipes and identified by lighter combustion.

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.
