Problems solved by technology

In various fields and special environments, more and more attention is paid to the quality and characteristics of industrial hoses. At the same time, the use environment of industrial hoses is harsh, and the requirements for the comprehensive performance of industrial hoses are also increasing. High, general industrial hoses only have a few characteristics such as corrosion resistance or high strength, which cannot meet the special requirements for industrial hoses in some special environments. These limit the use of hose
