PPH Pipes: An Outstanding Pipeline Material

  PPH pipes, namely homopolymer polypropylene pipes, play a significant role in various industries due to their excellent properties. Their resistance to chemical corrosion is remarkable. They can well withstand highly corrosive media such as sulfuric acid with a concentration as high as 80%, nitric acid at 50%, and hydrochloric acid at 30%. This makes them highly favored in industries like chemical engineering and pharmacy where the corrosive environment is rather harsh. 

  In terms of water flow transportation, the roughness coefficient of their inner walls is as low as 0.007 - 0.011. Compared with traditional cast iron pipes, they can significantly reduce the water flow resistance and improve the water delivery efficiency by approximately 30%. Thus, they have obvious advantages in water supply and drainage engineering. 

  The heat distortion temperature of PPH pipes can reach around 135 °C, and they can operate stably even when transporting hot water at 95 °C, meeting the requirements of the hot water supply systems in buildings. Moreover, their density is only 0.9 - 0.91 g/cm³. Compared with metal pipes, their weight is greatly reduced, and about 50% of the labor cost can be saved during installation. They bring both high efficiency and economic benefits to engineering construction and are an ideal choice for modern pipeline projects.
