THERMA-TUBE PRE-INSULATED PIPES

THERMA-TUBE PRE-INSULATED PIPES

Hermans Techniek has been a supplier for pre-insulated steel pipes for more than 30 years. Installers at home and abroad are successfully using our Steel/PUR/PE pipes and our experience in this area. The pre-insulated steel piping system (district heating) is the most widely used system for heating networks. At our location in Bergschenhoek, we have a stock of Therma-Tube pre-insulated steel pipes. This allows us to supply materials from stock in the event of emergency orders, provided the stock has not been sold out. As a result, the materials can be delivered to your project within 24 hours. For export orders, Hermans Techniek can assist you in transporting the materials to many destinations in Europe and beyond.

 

For installers from the non-residential building sector, Hermans Techniek can also provide the installation of the pipelines, for which we are SCC* certified.

 

Both Hermans Techniek and the factory are ISO certified. The pipes on the site are also certified in accordance with the Euroheat & Power guidelines for pre-insulated pipes. The factory complies with the environmental requirements stipulated in 14001:1998.
