Comparison of drainage system products!

　　Comparison of Advantages between PP Silent Drainage System and Cast Iron Drainage System: Superior noise reduction performance compared to cast iron pipes; Noise reduction is achieved by adding special materials to adjust the density and microstructure of the pipe, absorbing audible sound waves and preventing their transmission. The Chinese Academy of Sciences evaluated the overall noise reduction performance of 110 PP silent pipes. The results showed that the noise reduction of uPVC pipes was 56 decibels, cast iron pipes was 46.5 decibels, and PP silent pipes was 45 decibels. The noise reduction effect is superior to cast iron pipes. Corrosion resistance and oxidation resistance result in a longer lifespan than cast iron pipes, leading to higher overall economic efficiency; Polypropylene silent pipes are commonly used to manufacture PPR water and hot water pipes. They share the same polypropylene raw material and possess acid and alkali resistance. The service life of PP silent pipes is guaranteed for 50 years, while cast iron pipes have a lifespan of 30 years, and hotel pipes last 10-20 years. We are currently undertaking several hotel renovation projects to demonstrate this, such as the Shanghai Pudong Holiday Hotel and the Five-Star Ocean Hotel. The production standard for polypropylene silent pipes is 5 kg/cm2, while cast iron pipes are 4.5 kg/cm2. The production standard for polypropylene silent pipes is 5 kg/cm2, and for cast iron pipes it is 4.5 kg/cm2.

　　Other Technical Indicators of PP Polypropylene Silent Drainage System [High Temperature Resistance]: PP polypropylene silent pipes, unlike other piping systems, possess high-temperature resistance. Drainage pipes can withstand long-term exposure to temperatures of 95 degrees Celsius. Softening occurs around 150 degrees Celsius. Other drainage pipes cannot withstand this temperature.

　　The PP silent drainage system has been tested and verified by authoritative testing and research institutions of the Chinese Academy of Sciences, meeting noise reduction standards exceeding those of cast iron pipes. We welcome hotel management companies, construction companies, and professionals to analyze and test our product quality. Superior sound insulation is achieved by incorporating special materials to adjust the density and microstructure of the pipe, absorbing audible sound waves and preventing their transmission. The noise reduction effect is significantly better than that of cast iron pipes. In short, the polypropylene silent drainage system has been widely used in engineering projects. Although it is a new type of pipe, the basic raw materials are widely used in the building materials industry, making it a mature product. The PP polypropylene silent drainage system has lower construction costs, a longer lifespan, and better noise reduction than cast iron pipe systems. It has been recognized by many foreign hotel companies and is used in construction projects.
