Plastic cones

Plastic cones are key components in modern sewage and drainage systems. At Onninen we offer a wide range of these products. Our cones meet the highest quality standards. They are made of durable plastics. They provide reliable connections for pipes of different diameters. Thanks to them, installations operate smoothly for years.

Our offer includes PP cones and cones without a seal. They are available in black and orange. The variety of options allows you to choose the right element for each installation. Plastic cones have many applications in construction and industry. They work well in both new projects and modernizations.

Types and applications of plastic cones

Plastic cones are divided into several basic categories:

Reduction cones - connect pipes of different diameters
Centric cones - have a symmetrical shape
Eccentric cones - with offset axis
Cones with and without seal

In practice, plastic cones are used in many industries. In sewage systems, they connect pipes of different cross-sections. In industrial installations, they enable the change of flow direction. Cones are also used in ventilation and air conditioning. They are used in the construction of tanks and silos.

We recently used PP cones in a project for a large production plant. This allowed us to effectively connect old and new sections of the installation. This avoided the costly replacement of the entire system. This shows how important a role these inconspicuous elements play.

Why choose plastic cones from Onninen?

At Onninen, we focus on quality and reliability. Our plastic cones come from renowned manufacturers. We offer products from the Kaczmarek and Wavin brands. These are proven solutions that professionals trust. Thanks to cooperation with leading manufacturers, we guarantee the highest quality.

We often come across the question about the durability of plastic cones. Our experience shows that when properly installed, they last for many years. They are resistant to corrosion and chemicals. They do not require maintenance, which translates into lower operating costs.

In the case of reorganization of sewage systems, reduction cones are most often used. They enable easy connection of pipes of different diameters. This solution works well in both construction and industry. It allows for flexible design of installations.

How to choose the right plastic cones?

Choosing the right plastic cone depends on several factors:

Type and diameter of pipes to be connected
Installation operating conditions (pressure, temperature)
Working environment (e.g. presence of aggressive substances)
Standards and regulations requirements

At Onninen we offer professional advice when selecting plastic cones. Our specialists will help you choose the optimal solution. We take into account the specifics of a given project and the individual needs of the client. Thanks to this, we are sure that the recommended products will fulfill their task.

Many customers ask us about the differences between cones with and without a seal. Cones with a seal provide a better sealing of the connection. They are ideal for installations operating under pressure. Cones without a seal are mainly used in gravity systems. The choice depends on the specific application.

In our daily practice, we see a growing interest in colored cones. Black cones are a classic, working well in most applications. Orange cones are gaining popularity in specialist installations. They facilitate identification and inspection of systems.

Onninen recommends using plastic cones from the same brand as the rest of the system. This ensures full compatibility and the best operating parameters. In case of doubt, it is always worth consulting our experts. We will help you choose the optimal solution for each project.
