The size of the PPH pipe supplied by this manufacturer is processed with homopolymer polypropylene (PPH) raw materials, and adopts a smooth and gradual change structure, which is specially designed for the transition connection of different diameter pipelines in the PPH pipeline system. Its material continues the characteristics of the PPH pipe, and the performance is stable in the temperature range of -10 ° C to 95 ° C. It is not easy to deform and crack in hot water or low temperature environment. The gradual change structure can reduce the flow resistance of the medium and avoid the pressure loss caused by the sudden change of the pipe diameter. At the same time, the interface closely fits the pipeline to prevent medium leakage. It is the core accessory of the PPH pipeline to achieve smooth diameter reduction. In terms of specifications and models, the PPH pipe size covers 20mm to 315mm commonly used diameter combinations (such as 50mm to 32mm, 110mm to 75mm, etc.), and the diameter reduction specifications are accurately matched with the same series of PPH straight pipes: small diameter combinations are suitable for household water supply, small equipment pipeline diameter reduction, medium and large mouth combinations meet the diameter reduction needs of commercial places, industrial mild wastewater pipelines and municipal auxiliary pipelines; manufacturers support the deployment of specifications according to wholesale orders, and can also supply PPH straight pipes and elbows in batches. The product has a wide range of use scenarios, suitable for family residential hot and cold water pipe diameter reduction, commercial complex water supply system diameter connection, food processing industry clean water pipeline transition, chemical industry low concentration solution pipeline diameter adjustment, etc., suitable for indoor surface installation, dark application or outdoor shallow buried installation. At present, the manufacturer supports batch wholesale, the price has advantages, and customers who are interested in purchasing PPH pipe size can directly call the contact information 13339996652 consult the details.
