From the bathroom drainage for home decoration to the rain water pipe network for municipal engineering, PVC plastic drainage pipes have long been "invisible but important" in our lives. The reason why it can stand out among many drainage pipes cannot be separated from three core advantages - light weight, corrosion resistance and low cost.

is first and foremost "light" to worry about. Compared with traditional cast iron pipes or galvanized steel pipes, PVC drainage pipes weigh only 1/5 to 1/10 of metal pipes. A 3-meter-long DN110 specification PVC pipe weighs less than 3 kilograms, and can be easily handled by decoration workers with one hand. There is no need to use heavy tools such as cranes and electric drills during installation. It can be spliced with simple bonding or buckling. This lightness not only saves construction time, but also reduces labor costs. It is especially suitable for the renovation of old houses or the operation of narrow spaces in high-rise residences - there is no need to worry about "moving pipes and climbing stairs".

The second is "durable" for a long time. Drainage systems face long-term erosion from acid and alkali substances, grease and even sediment in sewage, and PVC materials are chemically stable: they will not rust and corrode like metal pipes, nor will they be decomposed by organic matter like cement pipes. For example, oil in kitchen drains, detergent residues, or sun and rain in outdoor rain pipes will not cause real damage to PVC pipes. Under normal circumstances, the service life of PVC drain pipes can reach 20-30 years, which is almost 2-3 times that of metal pipes, which greatly reduces the trouble of later maintenance and replacement - many PVC drain pipes in old communities have been used for more than ten years, and they can still drain normally.

is finally "saving". The raw material cost of PVC pipes is lower than that of metal or cement, and coupled with the mature extrusion molding process, the price is only 1/3 to 1/2 of that of cast iron pipes. More importantly, the installation and maintenance costs are low: there is no need for complex processes such as welding and painting anti-corrosion paint during installation, and maintenance only requires regular cleaning of debris, which is almost no additional cost. The total cost of a 100-square-meter house with PVC as the whole house drainage system is at least 2000-3000 yuan less than that of galvanized steel pipes; for municipal projects, the large-scale use of PVC pipes can reduce the cost more considerable - this combination of "low cost + high life" is the key to its cost-effective choice.

In fact, the advantages of PVC plastic drainage pipes are far more than these three points, but these three core characteristics hit the most essential needs of the drainage system: easy to use, durable and save money. Whether it is home improvement or tooling, choosing it is not only choosing a pipe, but also choosing a "worry-free lifestyle" - after all, who does not want to let the drain pipe at home "work silently" for decades without worrying about frequent maintenance?
