Comparison of pp silent drainage pipe system and cast iron drainage pipe system products!

Comparison of Advantages between PP Silent Drainage System and Cast Iron Drainage System: Superior noise reduction performance compared to cast iron pipes; Silent: By adding special materials, the density and microstructure of the pipe can be adjusted to absorb audible sound waves and prevent sound waves from escaping. The Chinese Academy of Sciences evaluated the total noise reduction of 110 PP silent pipes. The results show that the noise reduction of uPVC is 56 decibels, cast iron is 46.5 decibels, and PP silent pipe is 45 decibels. The noise reduction effect is superior to cast iron pipes. Corrosion resistance and oxidation resistance; longer service life than cast iron pipes; higher overall cost-effectiveness; Polypropylene silent pipe materials are usually used to manufacture PPR water and hot water pipes and have the same polypropylene raw materials; they have acid and alkali resistance chemical characteristics. The service life of PP silent pipes is guaranteed for 50 years, the service life of cast iron pipes is 30 years, and the service life of hotels is 10-20 years. We are currently undertaking some hotel renovation projects to demonstrate this, such as the Holiday Inn Shanghai Pudong and the Five-Star Ocean Hotel. The production standard of polypropylene silent pipes is 5 kg/cm2 and that of cast iron pipes is 4.5 kg/cm2. The production standard of polypropylene silent pipes is 5kg/cm2, cast iron pipes

Other Technical Indicators of PP Polypropylene Silent Drainage System [High Temperature Resistance]: PP polypropylene silent pipes, unlike other piping systems, do not have high-temperature resistant material properties. Drainage engineering pipes can withstand high temperatures of 95 degrees for a long time, and the softening point is around 150 degrees Celsius. Other drainage pipes cannot withstand this temperature.

The pp silent drainage design system has passed the testing and research of authoritative testing institutions of the Chinese Academy of Sciences, and its noise reduction technology surpasses cast iron pipe products. Our products welcome hotel enterprises, construction units, and those with relevant professional knowledge for testing. Superior sound insulation: By adding special materials, we can adjust the density and microstructure of the pipe to absorb audible sound waves and prevent sound wave transmission. The noise reduction effect is significantly better than that of cast iron pipes. The difference between this and other PP polypropylene silent pipe drainage systems is that, in summary, polypropylene silent pipe drainage systems have been widely used in engineering projects. Although it is a new pipe material, the basic raw materials for making the pipes are widely used products in the building materials industry, so it is a mature product. The PP polypropylene silent pipe drainage system has a lower cost, longer service life, and better noise reduction effect than the cast iron pipe system. It has been recognized by many foreign hotel companies and is used in construction engineering.
