- SN8 - up to a depth of 8 m, under roadways and areas with high loads
| Stiffness class | Max depth SDR | Wall thickness 110mm | Application |
|---|---|---|---|
| SN2 | 2m | 2.7mm | Areas without traffic |
| SN4 | 6m | 3.2mm | Residential installations |
| SN8 | 8m | 3.2mm | Under roads |
Construction of PVC pipe 110 - solid vs foamed
In Onninen's offer, there are two types of PVC 110 pipe constructions available. Solid pipes with a uniform wall provide maximum strength and are recommended for the most demanding installations. Pipes with a foamed core offer an excellent strength-to-weight ratio, making transport and installation easier.
Our gravitational sewage systems are based on proven technical solutions that guarantee long-term trouble-free operation.
Practical applications of PVC pipe 110 in external projects
From our many years of experience in the installation industry, PVC pipe 110 finds wide application in various sewage systems. We particularly recommend these solutions for the sewage connections of single-family homes and larger residential investments.
Sanitary sewage systems
In Onninen's assortment, you will find PVC 110 pipes perfectly suited for building sewage levels. The diameter of 110 mm ensures adequate sewage flow while maintaining material economy. Our external PVC sewage pipes 110 from Kaczmarek are characterized by the highest quality of workmanship and the long-standing experience of the manufacturer.
Rainwater installations
PVC 110 pipes perform excellently in rainwater drainage systems. Their smooth inner surface minimizes flow resistance, which is particularly important during heavy rainfall. Our offer also includes complete systems along with fittings and connecting elements.

Sewage systems built from PVC 110 pipes require minimal maintenance. In case of the need for expansion or repair, the availability of materials from our warehouses allows for quick execution of work without prolonged downtimes.
Frequently asked questions
1. Will PVC pipe 110 withstand loads in external installations?
Yes, PVC pipe 110 performs excellently in external installations. In Onninen's offer, pipes are available in various stiffness classes - from SN2 to SN8, which withstand mechanical loads up to a depth of 8 meters. The proper selection of the stiffness class for the installation conditions is crucial.
2. What stiffness class of PVC pipe 110 will be best for my installation?
The choice depends on the laying depth and mechanical loads. We recommend SN4 for standard residential installations up to 6 m deep, SN8 under roads and areas with high loads, and SN2 for shallow installations without vehicle traffic. Our specialists will help in selecting the optimal solution.
3. Is PVC pipe 110 resistant to chemical substances in sewage?
The PVC-U material exhibits high chemical resistance in the pH range of 2-12. The pipes from our offer are resistant to the action of most chemical substances present in domestic and industrial sewage, including acids, bases, oils, and detergents, which guarantees long-term trouble-free operation.
4. What are the differences between solid and foamed PVC 110 pipes?
The solid pipe has a uniform wall and maximum mechanical strength. The foamed pipe contains a core made of foamed PVC, making it lighter and more economical while maintaining the required strength parameters. Both available in our assortment meet the standards for external installations.
5. Why are external sewage pipes orange?
