Riser/riser pipes - the basis of efficient sewage systems

Upstand and riser pipes are a key element of every sewage system.   At Onninen, we understand their importance perfectly. Our many years of experience allow us to offer the highest quality products. We often come across questions about selecting the right pipes. That is why we have prepared a comprehensive overview of this category.

Our offer includes PVC and PP shaft pipes. Each material has its advantages. PVC is characterized by high chemical resistance. PP, on the other hand, is more flexible. The selection depends on the specific application. Our specialists will be happy to advise on the optimal solution.

Types of riser/riser pipes available at Onninen

The range of shaft pipes in our wholesale store is very wide. It includes:

• Smooth pipes
• Flareless corrugated pipes
• Corrugated socket pipes
• Single-layer corrugated pipes
• Two-layer corrugated pipes

Multi-colored corrugated pipes are particularly popular.   They are available in orange and black versions. This makes it easier to identify cables in complex installations. In our daily practice, we see how important this is for efficient servicing.

We also offer pipes of different diameters. They are available in both DN/OD and DN/ID standards. This allows you to precisely match the pipes to the project. The lengths of the pipes are also varied. This allows you to optimize the number of connections in the system.

Criteria for selection of riser/riser pipes

Choosing the right riser pipes is a key decision. It affects the durability and efficiency of the entire system. Our experience shows that it is worth considering several important factors:

1. Type of transported medium
2. Required mechanical strength
3. Ground conditions
4. Foundation depth
5. Expected life of the installation

Recently, when working on a project for a large housing estate, we faced a challenge.   The ground was unstable and the foundation depth was significant. We decided on double-layer corrugated pipes. Their increased circumferential stiffness ensured the safety of the installation.

In the case of industrial systems, chemical resistance is key. PVC pipes are perfect for this. Their smooth internal surface facilitates flow. This reduces the risk of pipes becoming clogged.

Onninen recommends considering the assembly aspect as well. Socket pipes significantly speed up the installation process. This is particularly important for large investments. It shortens the implementation time and reduces labor costs.
