What is the difference between PVC-U pipe and UPVC pipe?

PVC-U pipes and UPVC pipes are easily regarded as the same pipe by some people because of their similar names. In fact, they have many differences. In order to allow everyone to better distinguish the two, here are three Let me introduce to you the difference between PVC-U pipe and UPVC pipe.

1. Features:

1. UPVC pipe, also known as hard polyvinyl chloride pipe, is a kind of pipe with strong corrosion resistance, acid, alkali, salt and oil medium corrosion resistance. It is light in weight, has certain mechanical strength, has good hydraulic conditions, is easy to install, but is easy to age and is resistant to high temperatures. , but cannot withstand impact. It is suitable for domestic water systems. Pipe fittings below DN50 are connected, and pipes above DN65 are connected by circles.

2. PVC-U pipe, also known as rigid polyvinyl chloride pipe, is a new type of drainage pipe formed by one-time extrusion by an extruder. The inner wall is smooth and the outer wall has vertical reinforcement ribs. It is suitable for residential drainage systems and uses "T" type rubber ring interface.

2. Design and material selection angle:

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

2. The frost resistance and heat resistance of UPVC pipes are not good. It has good anti-drying performance, strong corrosion resistance, low fluid resistance, high mechanical strength, hygienic and non-toxic, and good water tightness. PVC pipe is suitable for wire pipes and sewage pipes, and the installation of large overhead pipes with low strength requirements, such as power plants. Cooling Tower.

3. Construction angle:

1. PVC-U is mainly used for building water supply and drainage and pre-embedded pipes. The main construction methods are hot melt and glue, which is not easy to construct in winter.

2. UPVC is used for building water supply and drainage and sewage pipes. It can replace ordinary cast iron pipes and galvanized pipes. It is easy to install and can be installed with flanges and corresponding kits. There are no limitations in construction.

The above is the difference between PVC-U pipes and UPVC casting pipes introduced to you. I hope it will be helpful to you. If you need to know more about pipes, you are welcome to continue to pay attention.
