Large elbow for corner is one of the most commonly used PPR accessories. As an innovative manufacturer of high-performance plumbing products, Zhuji Primy Pipe Co., Ltd. Offers a full line of PPR pipes and fittings crafted to deliver strength, ease of use and an attractive appearance.
The international standard pressure rating for PPR tubes is usually determined by ISO and other international standards organizations. The following are the international standard pressure levels for some common PPR pipes:
1. ISO 15874: This is a standard published by ISO that specifies the technical specification for PP-R pipe materials and systems. The ISO 15874 standard includes different pressure levels, such as PN10, PN16, PN20, PN25, etc., to meet different application requirements.
2. DIN 8077/8078: This is the German standard for regulating the performance and dimensions of PPR tubes and fittings. The DIN 8077/8078 standard includes different pressure levels, such as PN10, PN16, PN20, PN25, etc., for the European market.
3. ASTM F2389：(ASTM) published standards that specify the performance and dimensions of PP-R tubes and fittings. This standard is usually used in North America, where the PP-R pipe Pressure rating specified in the (ASTM) published standard is usually expressed using Schedule (SCH), rather than the common PN (Pressure Nominal) rating. ASTM F2389 is the standard used to specify PP-R tubes and fittings, and generally covers the following two common PP-R pipe pressure classes: SCH 40: This is one of the more common PP-R pipe pressure classes specified in ASTM F2389. SCH 40 pipes are commonly used in low-pressure cold water supply systems and general applications, such as domestic water supply. SCH 80: SCH 80 is another PP-R pipe pressure class specified in ASTM F2389. SCH 80 pipes are commonly used in high pressure applications, such as some industrial water supply systems. These pressure grades are associated with ASTM standards and are generally suitable for the North American market. To select the appropriate PP-R pipe pressure rating, it is necessary to consider the specific application needs and local building regulations to ensure the performance and safety of the pipe. Please note that other countries and regions may use different standards and pressure levels to regulate PP-R pipes.
4. GB/T 18742: This is the Chinese national standard that specifies the technical requirements for PPR tubes and fittings. The GB/T 18742 standard includes different pressure levels, such as PN1.25, PN1.6, PN2.0, PN2.5, PN3.2 and so on.
These international standard pressure grades are usually applied to markets in different countries and regions to ensure the performance and safety of PPR pipes in various applications. When selecting PPR pipe materials and pressure levels, the right choice should be made according to the specific application needs and local building regulations, and ensure that the appropriate standards are met.
