There are many great rivers and streams with the total length for more than 172  thousand km in Khanty-Mansi Autonomous Area. In addition, more than 2/3 of this territory is occupied by swamps that surrounded by about 290 thousand lakes. Due to mentioned hydrographic conditions of Khanty-Mansi Autonomous Area dredging is well-developed in this region. The main feature of Khanty-Mansi Autonomous Area’s climate is that winters are severe and long with extended snow and ice covering and short summers so it is necessary to use the hoses with maximum resistance not only to abrasive wear but also to climatic conditions. In relation to mentioned characteristics of Khanty-Mansi Autonomous Area many companies choose Composit wear-resistant hoses for carrying out dredging works. For example, in 2018 our company-partner bought Composit hose of 530 mm inner diameter with universal plastic float. This hose is successfully exploited by our customer at the quarry in taiga of Yamal-Nenets Autonomous Area. This Composit hose is exploited even in conditions of subzero temperatures.
