Concrete Pipe vs Plastic Pipe – What’s the Difference

plastic pipe vs concrete pipe

There are numerous factors to consider when selecting the right type of piping for your project. Concrete pipe and plastic pipe are two of the most commonly used types of piping. But what is the distinction between them? And which is better for your project? Let’s look at the key differences between concrete and plastic pipes and why one might be better.

Difference Between Concrete and Plastic Pipe

When it comes to pipe materials, there are two main options: concrete and plastic. Each has advantages and disadvantages, making choosing the correct type of pipe for the job at hand is critical.

One of the most significant benefits of concrete pipe is its durability. Concrete is a tough material that can withstand a lot of abuse. It is also chemical and corrosive substance resistant, making it an excellent choice for sewer and stormwater applications. Concrete pipes, on the other hand, are very heavy, making transportation and installation difficult. Furthermore, concrete is not as flexible as plastic, so it can be difficult to work with in small spaces.

Plastic pipe, on the other hand, is significantly lighter than concrete, making it easier to transport and install. It is also more adaptable, making working in cramped quarters easier. However, plastic pipe is not as durable as concrete, so it may not be suitable for sewer or stormwater applications.

Finally, which type of pipe to use is determined by the project’s specific needs, budget, and goals.

Why is Concrete Pipe Frequently Regarded as Superior?

There are numerous reasons why the concrete pipe is considered superior to plastic pipe. For starters, concrete is far more durable than plastic and can withstand changes in temperature and pressure better. Furthermore, concrete is less prone to corrosion than plastic, so it will last longer and require less maintenance.

Concrete pipe is also far more environmentally friendly than plastic pipe. Concrete pipe will eventually decompose and return to the earth, whereas plastic pipe will take hundreds of years to decompose. As a result, concrete pipe is the obvious choice for those seeking to minimize their environmental impact.

Plastic Pipe and Concrete Pipe in Rainwater and Sewer Drainage

  • HDPE pipe has a flow capacity of more than 1.3 times that of concrete pipe. If DN800 concrete pipe is used, HDPE pipe requires only DN700 (800/1.3).
  • The HDPE pipe connection method is simple and quick, and the construction progress is greatly improved. Under normal conditions, only 30% of the cement pipe’s construction time is required, saving significant construction person-hours.
  • The standard length of the HDPE pipe is 6 meters, and it is made of high-density polyethene raw materials. The pipe is lightweight, and the required mechanical equipment is greatly reduced.
  •  HDPE pipe has a low grading coefficient, a small working surface, and can be welded on the ground, trench excavation can be reduced by more than 30%, saving engineering costnecessarynificantly.
  • The pipeline trench does not require basic treatment because HDPE pipe can adapt to the embedding of uneven settlement geology such as soft foundation.
  • HDPE pipe has a service life of more than 50 years, and the pipeline system has a life of more than 50 years. Theoretically, this is more than 2.5 times the life of concrete pipe, which is a long-term investment benefit.

What are the Main Drawbacks of Concrete Pipe?

While concrete pipe has many advantages, there are some disadvantages to consider. One of the most common problems is that if the concrete is not properly supported, it can crack and collapse. Furthermore, concrete pipes can be heavy, making transportation and installation difficult. And because it is a rigid material, concrete pipe may not be the best choice for projects that require a high degree of flexibility.

Despite these potential disadvantages, concrete pipe is still popular for many applications due to its durability and low cost.
