About PVC PIPE
PVC pipes (divided into PVC-U pipes, PVC-M pipes and PVC-O pipes) Rigid polyvinyl chloride pipes are made of polyvinyl chloride resin, stabilizers, lubricants, etc., and then extruded by hot pressing. The first plastic pipe to be developed and applied.

PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the seepage of PVC-U monomer and additives, it is only suitable for water supply systems whose conveying temperature does not exceed 45ºC. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems.

PVC-O pipe, Chinese name biaxially oriented polyvinyl chloride, is the latest evolutionary form of PVC pipe. The pipe manufactured through a special oriented processing process will use the extrusion method to produce the PVC-U pipe for axial stretching and diameter Stretching to make the long-chain PVC molecules in the pipe arranged biaxially, to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.

Advantages of pipe

1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.

2. Low fluid resistance: The wall of PVC-U pipe is very smooth and has little resistance to fluid. Its roughness coefficient is only 0.009. Its water delivery capacity is 20% higher than that of cast iron pipes of the same diameter and 40% higher than that of concrete pipe %.

3. Excellent corrosion resistance and chemical resistance: PVC-U pipes have excellent acid resistance, alkali resistance, and corrosion resistance, and are not affected by damp water and soil pH. No anti-corrosion treatment is required when laying pipes.

4. It has good water tightness: the installation of PVC-U pipes, whether by bonding or rubber ring connection, has good water tightness.

5. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be corroded by rodents. According to a test conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.

6. Performance test: curing time, shrinkage, splitting strength, tensile performance, peeling strength, thermal stability, pot life, storage period, release of harmful substances.

Disadvantages of pipe

1. Not suitable for hot water pipes, but not suitable for direct drinking water supply pipes.
2. Easily brittle when impacted.

3. Some low-quality counterfeit UPVC pipes have plasticizers added in their production, which can cause media pollution and greatly shorten the aging period of UPVC pipes.
 

PVC pipe application

PVC pipes have been used for a long time and chloride ions are precipitated. They are not suitable for tap water pipes. They have poor impact resistance and are not suitable for gas pipes. However, PVC pipes are low in price, high in hardness, and are affected by temperature. Water supply pipes and drainage pipes are used for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, and vegetation watering.

The difference between PVC-U and UPVC

PVC-U and UPVC are what we usually call PVC pipes, but the order of writing is different.

In the PVC production process, in order to increase the plasticization performance of PVC and improve production efficiency, plasticizers (such as DOP, DBP, DINP, etc.) will be added, and the PVC products with plasticizers will be softer.

Generally, we refer to PVC products without plasticizers added during processing as UPVC, or PVC-U.
