ווי צו קלייַבן PPR פּייפּס?

PPR פּייפּס have become the preferred choice for pipe renovation due to their energy efficiency, ליכט וואָג, הויך שטאַרקייַט, קעראָוזשאַן קעגנשטעל, אאז"ו ו. אָבער, attention should be paid to the problem of low-temperature brittleness. When purchasing, look for national standards and products from large factories. During construction, avoid rough handling and direct sunlight.

פֿעיִקייטן & אdvantages of PPR פּיפּס

PPR pipes are widely used in building water supply and pipe renovation due to their energy efficiency, environmental friendliness, ליכט וואָג, high strength and corrosion resistance. It is not only energy-saving and material-saving, but also in line with the concept of environmental protection. Moreover, it is lightweight, strong and highly resistant to corrosion. Its inner wall is smooth and not prone to scaling, making construction and maintenance easy, and with a service life of several decades, it is undoubtedly an ideal choice for pipe renovation.

נידעריק-טיאימפעראטור Brittleness פּroblem of PPR Pipes

As PPR pipes are a new type of water supply pipe, our understanding of them is not deep enough. PPR פּייפּס, as random copolymer polypropylene, have unique properties that determine the brittleness that may occur in low-temperature environments. When the temperature is below minus 5 degrees Celsius, the flexibility of the pipe decreases and the rigidity increases, thus showing brittle characteristics. Under the influence of external forces, especially impacts and drops during handling, the pipe may crack in a straight line, and the cracking will start from the inner pipe and extend outward. This crack may not be noticeable at first, but if the pipe is cut off from the crack line during construction, the crack line will quickly extend along the axis. As a result, genuine PPR pipes can be smashed in low-temperature conditions, while adulterated or counterfeit PPR pipes may exhibit the opposite properties.

שtandards and מanufacturer שelection of PPR Pipes

When purchasing PPR pipes, pay attention to whether they comply with relevant standards such as GB/ T18742-2002 “Plastic piping systems for hot and cold water – PP – טייל 2 פּייפּס” and GB/ T18742-2002 “plastic piping systems for hot and cold water – PP – טייל 3 פיטינגז”. A genuine PPR pipe should have excellent performance and a service life of more than 50 יאָרן. Therefore, it is recommended that consumers choose PPR pipes produced by large manufacturers, which are of reliable quality and have a large market share, to ensure that they purchase truly standard-compliant products and enjoy perfect after-sales service.

Construction Tips

PPR pipes should follow the GB/T50349-2005 standard scheme during storage, handling and construction. Although PPR pipes may show brittleness at low temperatures, it can be effectively prevented by taking appropriate measures such as handling with care, avoiding dragging and dropping. During construction, although PPR pipes have a certain degree of flexibility, we must keep the pipes naturally straight and avoid excessive bending or forced twisting, because there is a fatigue strength limit for any material. אין דער זעלביקער צייַט, PPR pipes should not be exposed and should not be used for long periods in the sun. If they need to be used outdoors, they should be protected with dark sleeves.
