1、PPR pipes have various specifications, including distinctions between cold water pipes and hot water pipes. Cold water pipes are marked with a blue indicator, while hot water pipes are marked with a red indicator. Additionally, the pipes have different markings, such as S5, S4, S3.2, or S2.5.
2、Both of these refer to cold water pipes, which have relatively thinner walls. The latter two refer to hot water pipes, which have comparatively thicker walls.
3. If measured according to the specifications commonly used for hot water pipes, there are various types such as PN20, PN25, PN16, and PN32. Here, the measurement is based on the nominal outer diameter, which is expressed in DN. The nominal diameter typically refers to the average outer diameter and is used as a reference value. However, there may be some differences between the nominal diameter and the actual pipe dimensions. In imperial units, the pipes would be classified as 1/4 inch, 3/8 inch, or 1 inch.
4. For example, if you choose a 4-inch pipe, its outer diameter is approximately 20 millimeters, and its nominal diameter is DN15. If you choose a 6-inch pipe, the outer diameter of this PPR pipe is 25 millimeters, and its nominal diameter is DN20. If you choose a 1-inch pipe, its outer diameter is 32 millimeters, and its nominal diameter is DN25.
Two. What is the length of one PPR pipe?
1、PP-R pipes are typically sold in standard lengths of 4 meters per pipe. Therefore, PPR water pipes available on the market usually have a standard length of around 4 meters, with some also available in 6-meter lengths. However, many manufacturers can customize the length of PPR pipes according to customer requirements.
2、Because PPR pipes have various specifications, such as those with engineering diameters of 20mm, 25mm, 32mm, and some that can reach 160mm, but are typically set in lengths of 4 meters.
