Composit successfully cooperates with companies in the Southern Federal Area and supplies our products there. Composit representatives regularly visit this region in order to provide author’s supervision for the installed hoses. In April our employees visited the company in the Southern Federal Area, where Composit rubber lined hose of 426 mm diameter 3 m in length had been installed in February 2019. Since then, Composit hose has been successfully operating without any complaints from the customer-company. We would like to mention that this type of hose was installed outside at the transportation line for the first time. Previously, Composit rubber lined hoses were installed at the territory of other companies only in an enclosed space.
