Modern sewage manholes are composed of several basic parts: a base, i.e. a base connected to the pipeline, a shaft pipe and a telescope with a manhole. The fundamental element of a telescopic well termination is a telescopic pipe. The system constructed in this way is characterized by tightness, durability and resistance to mechanical damage and difficult environmental conditions. In this article, we explain what exactly a telescopic pipe is and what it is used for, and the difference between solid and foamed pipes. We also advise on the criteria to be followed when choosing a telescopic cover. We invite you to read and conveniently shop online.

What is a telescopic tube?
The telescopic pipe belongs to the category of accessories intended for plastic wells - just like a gasket or a telescopic cover. It is used to connect a corrugated shaft pipe with a manhole. For this reason, it is often factory equipped with handles (hooks) for the cover.
You can choose between telescopic pipes with and without a seal. In hydraulic stores, including our wholesaler, you can buy both a telescopic pipe with the required parameters, as well as a complete telescope with a full cover. The telescope is a component of a sewer well that allows for compensation for settlement that may occur after installation as a result of periodic temperature changes and dynamic loads caused by road traffic.
Allows you to correct the height of the manhole. It is installed to a specified maximum depth. Its use eliminates the problem of transferring loads to the base of the well. Additionally, the telescope increases the flexibility of the system. If, for example, road renovation is necessary in the future, a manhole equipped with a telescopic pipe can be easily adapted.
What is the difference between a solid telescopic pipe and a foamed one?
PVC pipes are divided into solid and foamed. The foamed telescopic pipe is a technologically advanced solution, produced in the co-extrusion process. It consists of three layers: two external plastic layers and a central wall made of foamed PVC. The foamed layer makes the product light and at the same time extremely durable.
Foamed pipes are used, among others, in the construction of sewage connections for single-family houses and larger areas intended for investments. The solid telescopic pipe, on the other hand, has a single-layer structure (one wall). It is used to build underground non-pressure drainage systems. It is characterized by excellent resistance to impacts, vibrations and mechanical damage, guaranteeing full tightness of the installation.
What should you consider when choosing a telescopic cover?
The telescopic cover is another important element of the sewage well telescope. It should be made of high-quality materials, characterized by increased durability and resistance to extreme temperatures and discoloration caused by atmospheric factors. A good cover is resistant to ground subsidence and effectively compensates for surface movements, especially in winter. When purchasing a well cover, you should pay attention to such parameters as:
- material (you can choose plastic, cast iron or concrete covers),
- pressure resistance (load class),
- shape (e.g. square models are easier to enclose with cubes and install directly at the curbs),
- diameter (must correspond to the diameter of the well),
- assembly method.
