Corrugated pipes are widely used in various industrial fields. They can often be found in cars, devices and machines of various types, as well as public utility facilities. What is a corrugated pipe used for? What are its types and how to connect them properly?

Intended use of corrugated pipes
Most often, corrugated pipes are used to protect wiring. The cable bundle is placed inside the pipe, which protects against damage. The great advantage of this solution is the durability of the product, because the commercially available variants of corrugated pipes are made of durable materials, such as PP or PE. At the same time, they are flexible and flexible, which allows them to be placed virtually anywhere, adapting their shape to specific conditions. Durability and flexibility were combined due to specific manufacturing methods.
The primary task is therefore to protect the installation, but thanks to properly used corrugated pipes, any repairs in the future will be much easier. An additional advantage is that corrugated pipes can be installed both inside and outside buildings. High durability means that they can also be easily placed in the ground.
Connecting a corrugated pipe
The effectiveness of protection depends on the proper implementation of the entire installation. Corrugated pipes should be connected using special, dedicated solutions. Properly fitted connectors make the connection points resistant to tearing. Additionally, thanks to the connector, the entire installation is really simple and quick. Most fittings also enable the appropriate connection of corrugated pipes with rigid pipes.
The connection is made using special connectors. The CR snap connector is used to connect two corrugated pipes as well as corrugated and rigid pipes. The connector variant is matched to the pipe variant, the most important thing is to select the right diameter to ensure that the whole thing is tight. Both ends of the pipe to be connected are placed inside the connector, and then the whole thing is closed (snapped), the connection is tight, durable and solid.
Types of corrugated pipes
Corrugated pipes are also called casing pipes, due to the function they perform. The products are available in various variants, i.e. with different diameters and wall thicknesses, but it is worth knowing that you should pay attention not only to specific technical parameters, but also to the intended use.
The following product variants can be distinguished among protective pipes for installation in the ground:
- type A pipes, i.e. smooth-walled, socket models, used in normal field conditions when exposed to relatively small external loads,
- SRS casing pipes, smooth-walled, socketed, with a solid wall, which are perfect for difficult conditions when transport loads are maximum,
- SRS-X pipes - smooth-walled and socketed, intended for difficult terrain conditions, most often used for laying in trenches, with a three-layer structure - the core is black, and the inner and outer layers are colored,
- SRS-G pipes, also marked as RHDPEp, are smooth-walled casing pipes, produced without a socket connector, they are connected together by welding, they are characterized by high load resistance, laid in difficult field conditions,
- SRS-GX pipes, smooth-walled, without a socket connector, which are connected together using connectors or welding,
- OPTO pipes (RHDPE) used primarily as a cover for fiber optic cables, telecommunications cables, as well as cable pipelines,
- DVK pipes, i.e. double-wall pipes with a smooth interior and a corrugated outer layer, are characterized by high stiffness,
- DVK(H) pipes, double-walled casing pipes, which are characterized not only by high stiffness, but also by excellent parameters protecting against compression at the level of N750,
- DVK-T - double-walled protective pipes with a waterproof connector, are used in the same way as DVK pipes, but are waterproof,
- DVK-T(H) - these are double-walled protective pipes, with a watertight connector, with high stiffness and compression resistance.
The casing pipe variant should always be adapted to the needs of a given project.
Corrugated pipes available from the Onninen wholesaler
DVK 160 red pipe
The DVK pipe is a double-walled red pipe , which is smooth inside and corrugated outside. Used as a cover for cables in open trenches. It allows you to secure cabling in bushings under roads, streets and tracks. A dedicated M-type connector is used for connection. The product is characterized by high compression resistance of N450.
DVK 110 blue pipe
DVK 110 blue casing pipes are resistant to compression. They are characterized by high rotational stiffness. Made of HDPE polyethylene, they are used in open excavations, as culverts under tracks, roads and streets.
QRK 110 blue pipe
Cables located underground should also be properly secured. For this purpose, corrugated pipes are used, such as the QRK 110 blue pipe . By choosing this variant, you also receive properly matched connectors and cables that make it easier to tighten the cables. A characteristic feature of the product is its high flexibility and small bending radius.
