PPR pipe is also called polypropylene pipe. It is a popular material for the waterway reconstruction and heating system in the home life of ordinary people. In order to avoid hidden dangers in concealed works such as waterways and heating, it is especially important to choose high-quality PPR pipes. How to distinguish the quality of PPR pipes? Touch First touch the surface of the pipe with your hand and experience whether the texture is fine and the particles are even. Nowadays, PPR pipes on the market mainly have white, gray and green colors. Under normal circumstances, recycled plastics cannot be made white, so many people often think that white is the best. In fact, this view is one-sided. As technology improves, color is not the standard for distinguishing PPR tubes. Two smells Keep your nose close to the tube and smell it smell. Because the main material of the PPR pipe is polypropylene, the good pipe has no odor, and the bad one has some strange smell. This is probably because polyethylene is blended in the polypropylene, so the odorous pipe is best not to be selected. Three pinch The high-quality PPR pipe has a certain hardness, and it is pinched and pinched with fingers, and the hand feel is hard and does not easily deform. Pipes that appear to be very elastic and easily deformed are either of a quality problem or a PPR tube. Four Good quality PPR pipe has a certain resilience, toughness and not brittleness. Pipes that can be smashed with medium strength are not good PPR pipes. However, the hardness is not equal to the elasticity. PPR pipes that are not broken are also carefully considered. Because some unscrupulous manufacturers increase the hardness of the pipe by adding too much impurities such as calcium carbonate, such pipe has poor toughness and is prone to brittle cracking over a long period of time. Five burning As the saying goes, real gold is not afraid of fire, use the fire method to test the PPR tube, it is very intuitive and very useful. Good PPR pipe is smokeless and odorless after burning. The molten liquid is clean and transparent. The inferior pipe may be black smoke or even pungent smell during the combustion process due to the internal mixing of recycled plastic or other impurities.
