Areas of application

Our TML pipes were specifically developed for laying directly in the ground in accordance with DIN EN 877 and connect building construction with the sewer system. The high-quality coatings of the TML range provide maximum protection against corrosion, even in aggressive soils. This makes the parts suitable even if the pH value of the soil is high. Due to the high compressive strength of the pipes, installation is also possible for heavy-duty loads in roads under certain circumstances.
