Types of steel pipes and their applications

Steel pipes are divided into several basic types. Each has its own unique properties and purpose. Threaded painted steel pipes are suitable for above-ground installations. They are corrosion-resistant and easy to install. Galvanized pipes, on the other hand, work better underground. They protect against moisture and aggressive environments. For industry, we recommend stainless steel pipes. They are resistant to chemicals and high temperatures.

In our daily practice, we see a growing interest in PE pipes. They are light and flexible. They are ideal for water supply networks. They do not corrode and are frost-resistant. For gas installations, we recommend seamless steel pipes. They guarantee the highest level of safety. They are tested under high pressure.

Accessories for steel pipes - essential elements of every installation

Accessories are key components that ensure the tightness and functionality of the pipe system. Our offer includes a full range. Separate pipe ends make it easier to connect elements. Concrete coalescing separators protect the environment. Grommets protect the installation when passing through walls. PE nozzles enable the connection of pipes made of different materials.

Particular attention should be paid to pipe elbows. We offer galvanized and painted versions. Threaded elbows ensure quick and secure assembly. For sewage installations, we recommend PVC ends. They are available in internal and external versions. They guarantee tight connections.
