You’re probably familiar with PVC pipe. It's the white plastic pipe commonly used for plumbing and drainage. PVC stands for polyvinyl chloride, and it’s become a common replacement for metal piping. PVC’s strength, durability, easy installation, and low cost have made it one of the most widely used plastics in the world. PVC is a thermoplastic material that is molded into different shapes to create pipes, fittings, valves and other liquid handling supplies.

Earlier we introduced UPVC,so what is CPVC?

You can think of CPVC as PVC’s cousin. They are similar in many ways, but they shouldn't be used interchangeably. Both are made of the same basic elements with one distinguishing factor. CPVC is altered by a free radical chlorination reaction that effectively increases the chlorine content of the material. CPVC is also a thermoplastic that is molded into many of the same products as PVC.

The main difference between CPVC and PVC is the range of temperatures each is capable of withstanding. CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing.

Let's see about the difference between pvc and upvc tube.

First, the characteristics are different:

1. UPVC pipe is also called hard polyvinyl chloride pipe. It is a kind of corrosion resistant, acid and alkali resistant oil medium erosion, light weight, certain mechanical strength, good hydraulic conditions and convenient installation, Self-extinguishing and flame retardation, The inner wall is smooth and the surface tension of the inner wall is small, it is difficult to form the scale. The toughness of the UPVC tube is low, the linear expansion.but Easy to aging, high temperature resistance, but can not withstand impact, suitable for domestic water system, pipe fittings below DN50, more than DN65.

2. PVC pipe is also called rigid polyvinyl chloride pipe. It is a new type of drainage pipe which is extruded by extrusion machine with smooth inner wall and vertical reinforcing rib on the outer wall. It is suitable for residential drainage system. "Type rubber ring interface.

Second, the design selection angle is different

1. PVC is mainly used for building water supply and drainage, light and durable, beautiful color, smooth and smooth, anti-aging, long service life, excellent physical and chemical properties, chemical corrosion resistance and high impact strength.

2. UPVC pipe has poor anti-freezing and heat resistance. It has good anti-drying performance, strong corrosion resistance, low fluid resistance, high mechanical strength, hygienic non-toxicity and good water tightness. PVC pipe is suitable for wire and sewage pipelines. And installation of large overhead pipelines with low strength requirements, such as power plant cooling towers.

Third, different construction purposes

1. PVC is mainly used for building water supply and drainage, irrigation systems and pool circulation systems. It is easy to cut into smaller pieces and can be fastened with glue, making it a good alternative to metal.

2, UPVC is used for building water supply and drainage, sewage pipelines, can replace ordinary cast iron pipes, galvanized pipes, easy to install, is often used for sewage lines and exterior drainage pipes. Even so, uPVC piping is much less common in the U.S., where PVC piping is preferred.

Neither PVC nor uPVC is used to transmit drinking water. cPVC (chlorinated polyvinyl chloride) is used instead.

Which pipe is better CPVC or uPVC?

Sometimes PVC is chlorinated using free radical chlorination in order to obtain CPVC. It has more improved properties than both PVC and UPVC. The main difference between UPVC and CPVC is that UPVC is made without adding plasticizers whereas CPVC is made by adding plasticizers and it is chlorinated as well.

As mentioned before, CPVC is more suitable for hot water applications up to 200F. PVC is still often used for unheated water as well as for vent and drainage systems; however, CPVC has become widely used for both hot and cold potable water.

The more resistant properties of CPVC make it useful for commercial and industrial applications as well. Because of its wider range of applications, CPVC is usually pricier than PVC. That being said, it is still a very cost-effective and versatile material.
