Definition of PPR pipe and PVC

PVC pipe: the full name is Polyvinylchlorid drainage pipe, which is a vinyl polymer material, and its material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, resistance to climate change and excellent geometric stability.

PVC has strong resistance to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. The pipe made of this material is called PVC pipe.

PVC pipe is a kind of pipe product with strong toughness, good heat resistance and good ductility. It consists of three parts: upper layer, middle layer and lower layer. The upper layer of PVC pipe is a layer of paint film, which plays the role of waterproof and anti-aging; the middle layer is PVC layer, which is the most important base layer; agent. There are many specifications and models of PVC pipes, because its use can be divided into two types: drainage pipes and line pipes, so there are many product classifications. 32-50mm and 75-110mm are commonly used in home decoration.

PPR pipe: full name polypropylene random copolymerized polypropylene (PPR) for water supply pipes has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique high quality of random copolymerized polypropylene. The advantage of transparency. It can be used as both cold water pipe and hot water pipe. As a new type of water pipe material, PPR pipe has unique advantages. It can be used as a cold pipe or a hot water pipe. Because of its non-toxic, light weight, pressure resistance and corrosion resistance, it is becoming a popular s material. Also suitable for hot water pipes and even pure drinking water pipes. The interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together, so once the installation pressure test is passed, it will not age and leak for a long time like the aluminum-plastic pipe, and the PPR pipe will not scale.
