PPR түтүктөрүн кантип тандоо керек?

PPR түтүктөр have become the preferred choice for pipe renovation due to their energy efficiency, жеңил салмак, жогорку күч, коррозияга каршылык, жана башкалар. Бирок, attention should be paid to the problem of low-temperature brittleness. Сатып алууда, look for national standards and products from large factories. During construction, avoid rough handling and direct sunlight.

Өзгөчөлүктөрү & Аdvantages of PPR Пips

PPR pipes are widely used in building water supply and pipe renovation due to their energy efficiency, экологиялык тазалык, жеңил салмак, 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.

Төмөн-Тимпература Вrittleness Пroblem of PPR Pipes

As PPR pipes are a new type of water supply pipe, our understanding of them is not deep enough. PPR түтүктөр, 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 градус Цельсий, 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.

Сtandards and Мanufacturer Сшайлоо 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 – Part 2 түтүктөр” and GB/ T18742-2002 “plastic piping systems for hot and cold water – PP – Part 3 арматуралар”. A genuine PPR pipe should have excellent performance and a service life of more than 50 жыл. Ошондуктан, 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. Ошол эле учурда, 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.
