How to choose PE corrugated pipe for outdoor drainage project?

Some basic information about PE corrugated pipe

What is a PE corrugated pipe? As soon as you hear the name, you should know that from the outside, its surface looks like a corrugated pipe, which is also the origin of its name. If you do not know enough about it, you will not know how to choose them. Today, let me talk about how to choose PE corrugated pipe for outdoor drainage project in detail.

When it comes to how to choose PE corrugated pipe for outdoor drainage project, first of all we need to understand some basic information about PE corrugated pipe.

1. PE double-wall corrugated pipe and PE single-wall corrugated pipe

What most of us are familiar with is PE double-wall corrugated pipe. As long as PE drainage corrugated pipe are mentioned, the picture of PE double-wall corrugated pipe will involuntarily appear in everyone's mind. After all, most construction teams are using it, so it The images in our minds are profound. In fact, what many people don't know is that it also has a brother called PE single-wall corrugated pipe. A corrugated pipe with inner and outer walls is called a single-wall corrugated pipe, which looks like a single wall. Only the surface has corrugations, but the inner wall has no corrugations, which is the double-wall corrugated pipe that I am familiar with. As for when to choose PE single-wall corrugated pipe and when to choose PE double-wall corrugated pipe, we will explain in detail in future articles.

2. PE drainage corrugated pipe additives

1. Plasticizer

Adding plasticizer to PE drainage corrugated pipe will greatly improve its fluidity and plasticity, but it will also reduce its tensile strength.

2. Filling

Adding fillers to the PE drainage corrugated pipe will increase the strength and elongation at break of the impact PE drainage corrugated pipe.

3. Colorant, lubricant

When adding colorants and lubricants to PE drainage corrugated pipe, we must pay attention to the compatibility of the deposition phenomenon of the pipe and the solution.

Adding these additives in the production process can greatly improve the performance of PE drainage corrugated pipe, so that they can better meet our use requirements. When we purchase PE drainage corrugated pipe, we must choose manufacturers with mature production technology and rich production experience. They can accurately grasp the amount of additives used to ensure the production of PE drainage corrugated pipe that best meet the requirements.

Why do we choose PE corrugated pipe in outdoor drainage project?

The emergence of PE corrugated pipe not only improves the efficiency and quality of the project, but also replaces traditional cement and steel pipes, shortening the construction period and reducing the cost of the project. So besides these reasons, what are the reasons for us to choose PE corrugated pipes in the outdoor drainage project?

1. First of all, look at the raw material of PE corrugated pipe, polyethylene. The PE corrugated pipe produced by this material is characterized by being very light, which is much lighter than traditional pipes, so both transportation and storage and installation have improved a lot.

2. Looking at the structure of the PE corrugated pipe, the outer wall is corrugated, which increases the pressure resistance of the pipe, and the inner wall is smooth without scaling, which reduces the impact force in the pipe, reduces the friction coefficient, and is more efficient to use.

3. The PE corrugated pipe is a plastic pipe, which still maintains the flexibility of the plastic, even in a relatively low temperature environment, so it is quick to socket and not easy to leak.

4. The raw materials used in the pipeline are non-toxic, harmless, tasteless, and not easy to be corroded, and the used PE corrugated pipes can be recycled for reuse.

5. There are many fields that can be applied, such as municipal drainage, residential area drainage, field irrigation, factory sewage discharge, etc.

The above advantages are the main reason why PE bellows are widely used, and its service life can be maintained for fifty years under normal circumstances, so it is easy to install, superior in performance, lower costs, and long in service life are the advantages of PE corrugated pipes performance.

The model and specification of PE corrugated pipes

Now, many of our door drainage projects will choose PE corrugated pipes. With the promotion and development of water supply in these years, PE corrugated pipes not only meet the single drainage demand, but the manufacturers of PE corrugated pipes have also slowly introduced many types and specifications.

PE corrugated pipes have been used to this day, and there are many specifications and models. Common PE corrugated pipes include DN100mm, DN160mm, DN200mm, DN300mm, DN400mm, DN500mm, DN600mm, DN700mm DN800, DN1000mm, DN1200mm and other specifications.

How to choose the PE corrugated pipe model for outdoor drainage project?

To choose a PE corrugated pipes with appropriate specifications, the specific model should be determined according to the actual situation of the project, but the actual situation is that there are many factors to be considered. Anyone who knows about PE corrugated pipes knows that the first thing we consider is the PE corrugated pipes. The ring stiffness of the pipe is the degree to which it can withstand pressure, so it is very important to judge the pipe with which ring stiffness to use. If it is too high, it will cause waste, and if it is too low, it will cause damage to the pipe.

1. The PE corrugated pipe is a flexible pipe, and the pressure it bears is the same as the surrounding soil. This is the so-called pipe-soil effect. According to this effect, when choosing the PE corrugated pipe, it is necessary to check the soil condition. Generally, the composition of the soil, the static load on the ground, and the dynamic load of whether there is a vehicle flowing above it should be considered. The ring stiffness of the PE corrugated pipes is considered based on these three items.

2. Consider the laying conditions of PE corrugated pipes, because the laying conditions are also very important under the condition of a certain external pressure load, and the soil conditions around the laying pipes should be considered at the same time. Because the soil of a pipeline route will also undergo some changes, these also need to be taken into consideration.

3. Construction conditions. The construction and installation of PE corrugated pipes must have certain requirements and must be operated in accordance with the standardized process. If the construction technology is qualified, the service life of the pipeline will also be improved, and the corresponding low ring stiffness can maintain good performance.

4. If the pipe diameter of PE corrugated pipe is less than 500mm buried water pipe, generally the ring stiffness should be ≥8KN/㎡, if it is confirmed that the geological conditions and construction conditions are better, you can choose ≥4KN/㎡. If the diameter of the pe bellows is 500-1200mm, the ring stiffness should be ≥8KN/㎡.

5. The backfilling after construction of the PE corrugated pipes will also be a consideration for our model selection. The backfilling density is considered. The backfilling density in the main area cannot be lower than 95%, and the sub-area cannot be lower than 90%.

How to choose the best PE corrugated pipe manufacturer?
