Hydraulic support pipes are used to make coal mine hydraulic supports and cylinders, columns, as well as other hydraulic cylinders and columns.

We have been committed to the development of hydraulic support pipes for coal mining systems, and have developed various series of products based on 27SiMn, which can meet the various needs of standards or users for hydraulic support pipes; The developed hydraulic support tube product for cold drawing can meet the cold drawing process requirements of users for the final product. At present, hydraulic support tube products have been widely used in major domestic coal mining machinery manufacturing enterprises such as Zhengzhou Coal Machinery and Beimei Machinery. With the improvement of unit equipment and production capacity, the development of oil cylinder pipes has been initiated, and oil cylinder pipes have been identified as another flagship product.
