In the early days, the Discharge Hose with Sandwich Flange was mainly used in the main conveying pipeline of dredgers. It is famous for its superior flexibility and has been widely used. Later, with the development of dredging engineering technology, the dredger became larger and larger, the bore size of conveying pipelines also became increasingly larger, and the working pressure of the pipelines was increasing as well. The Discharge Hose with Sandwich Flange is limited in use due to the limited tensile strength of its flanges, while the Discharge Hose with Steel Nipple can better adapt to the operation requirements in dredging projects as its fittings have higher structural strength, so it has been greatly developed.

At present, the Discharge Hose with Sandwich Flange is used in the main disharge pipelines in dredging projects. it is generally used in conveying pipelines with relatively small diameter(usually 600mm at maximum), and the working pressure of the pipelines is not greater than 2.0MPa.

All types of CDSR hoses are made of the most suitable materials. Our technicians will recommend suitable product types or design customized hoses according to the requirements of users in terms of pressure rating, wear resistance, bending performance and other properties, so as to meet the requirements of different operating conditions.
