PVC pipe is actually a polymerized substance of vinyl, and its material is a non-crystalline material. pvc materials are often used in practice with stabilizers, lubricants, auxiliary processing agents, colorants, anti-impact agents and other additives. It has non-flammability, high strength, resistance to weather changes and excellent geometric stability. PVC is highly resistant 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 is not suitable for contact with aromatic and chlorinated hydrocarbons. Pipes made from this material are called PVC pipes.
