The company Konvar has all the necessary licenses and certificates for the construction of main and connecting heating pipelines, as well as heating substations and pumping stations. We have all the necessary machinery as well as qualified personnel for the installation and welding of heat-shrinkable joints. From 2018. We also have Weldmaster devices for the installation of electrowelded joints, which due to their assembly technology and significantly better sealing of the welded joint are increasingly used in the construction of pre-insulated heating pipes.
