Corrugated pipes are widely used in various industries. They are often found in cars, devices and machines of various types, as well as public utility buildings. What is a corrugated pipe used for? What are its types and how to connect it correctly?

Purpose of corrugated pipes
Most often, corrugated pipes are used to protect cables. The cable bundle is placed inside the pipe, which protects it from damage. A big advantage of this solution is the durability of the product, because the variants of corrugated pipes available on the market are prepared from durable materials such as PP or PE. At the same time, they are flexible and elastic, which allows them to be placed almost anywhere, adapting the shape to specific conditions. Durability and flexibility were combined due to specific manufacturing methods.
The basic task is therefore to protect the installation, but thanks to properly used corrugated pipes, any repair 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 placed in the ground without any problems.
Connecting the corrugated pipe
The effectiveness of protection depends on the proper execution of the entire installation. Corrugated pipes should be connected using special, dedicated solutions. Properly matched connectors make the connection points resistant to tearing. Additionally, thanks to connectors, the execution of the entire installation is really simple and quick. Most connectors also allow for the proper 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 issue is to select the right diameter so that the whole is tight. Both ends of the pipe that are to be connected are placed inside the connector, and then the whole 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. Products are available in various versions, i.e. with different diameters and wall thicknesses, but it is worth knowing that attention should be paid not only to specific technical parameters, but also to the intended use.
Among the casing pipes for underground installation, the following product variants can be distinguished:
- Type A pipes, i.e. smooth-walled, socket models, used in normal field conditions when they are exposed to relatively small external loads,
- SRS casing pipes, smooth-walled, socketed, with a solid wall, which will work perfectly in difficult conditions when transport loads are maximum,
- SRS-X pipes - smooth-walled and socketed, designed for difficult terrain conditions, most often used for installation in trenches, with a three-layer structure - the core is black and the inner and outer layers are colored,
- SRS-G pipes, also known as RHDPEp, are smooth-walled casing pipes, manufactured without a socket connector, are connected by welding, are highly resistant to loads, and are installed in difficult terrain conditions,
- SRS-GX pipes, smooth-walled, without a socket connector, which are connected to each other using connectors or by welding,
- OPTO pipes (RHDPE) used primarily as a cover for fiber optic cables, telecommunications cables, and cable pipelines,
- DVK pipes, i.e. double-walled 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-wall casing pipes with a waterproof connector, used in the same way as DVK pipes, but they are waterproof,
- DVK-T(H) - double-walled casing pipes with a waterproof connector, high stiffness and resistance to compression.
The casing pipe variant should always be matched to the needs of a given project.
Corrugated pipes available at Onninen Wholesale
DVK 160 pipe red
The DVK pipe is a red double-walled pipe , which is smooth inside and corrugated outside. Used as a cable cover in open trenches. It allows you to protect cabling in culverts under roads, streets and tracks. A dedicated M-type connector is used for connection. The product is characterized by high compression resistance of the order of N450.
DVK 110 pipe blue
Blue DVK 110 casing pipes are resistant to compression. They are characterized by high rotational stiffness. Made of HDPE polyethylene, they are used in open trenches, as culverts under tracks, roads and streets.
QRK 110 pipe blue
Cables located in the ground must also be properly secured. For this purpose, corrugated pipes in coils are used, such as the QRK 110 blue pipe . By choosing this variant, you also receive appropriately matched connectors and ropes that facilitate pulling the cables. A characteristic feature is that the product is characterized by high flexibility and a small bending radius.
