Difference between PVC and PPR water pipe interior renovation

Introduction of PVC pipe

PVC named as polyvinyl chloride, is a non-chlorinated crystalline.

In practice, PVC materials often add stabilizers, lubricants, auxiliary processing, colorants, impact agents and other additives. It has non-flammability, high strength, weather resistance and good geometric stability.

The infectivity of PVC to this special case, reducing agent and strong acid at the same time. The produced pipe is called PVC pipe.

It is a pipe composed of upper and middle parts. PVC pipe is a lower layer of strong material, which has resistance and resistance; the middle pipe plays the role of a protective layer; it is a PVC layer, which is a classified layer; layer back The use of the base layer is very much the use of PVC pipe, because it has a wide range of uses, it is divided into two types of pipes and model pipes, so the home decoration products are commonly used in 32-50mm and 75-110mm.

Introduction to PPR Pipe

The full name is polypropylene propylene random. Water supply pipe random copolymer polypropylene (PPR) has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique high transparency advantages of random copolymer polypropylene. .

Can be used as both cold and hot water pipes. As a new type of water pipe material, PPR pipe has unique advantages. It can be used as both a cold pipe and a hot water pipe. Because of its non-toxicity, 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 and pressure test is passed, there will be no aging and water leakage like the aluminum-plastic pipe, and the PPR pipe will not scale.

What is the difference between PPR pipe and PVC pipe?

1. Different raw materials

The main material of PPR pipe is copolymerized polypropylene, so PPR pipe is also called three-type polypropylene pipe, while PVC is made of polyvinyl chloride material. The two pipes have different performance characteristics due to different main raw materials. It is also because of the raw materials that the PPR pipes are mostly hot-melted during installation, and the PVC pipes are mostly glued.

2, the price is different

The price of PPR tube is relatively higher

3. Different uses

PPR pipe is used as a water pipe, divided into cold water pipe and hot water pipe. PVC pipe is suitable for wire passing through wall and sewage pipe.

Which is better, PPR pipe or PVC pipe?

PPR tube is better. However, the scope of application is different and the characteristics are different. If it is only used for waterway transformation of cold water pipes, etc., from the quality point of view, PPR pipes are definitely better. But there is one thing that everyone should pay attention to, there are many PPR tubes that will say: Do not install. Not to be installed here means that it is installed outdoors and exposed to sunlight. If the PPR tube is installed outdoors, it must be replaced every two years, otherwise bacteria will breed and the service life will be greatly shortened. That's not as good as PVC.
