Pipe Float (Float for Dredging Pipes)
A Pipe Float is composed of steel pipe, flotation jacket, outer cover and retaining rings at both ends. The main function of the Pipe Float is to be installed onto a steel pipe to provide buoyancy for it so that it can float on the water. Its main materials are Q235, PE foam and natural rubber.

Armored Hose (Armored Dredging Hose)
Armored Hoses have built-in wear-resistant steel rings. They are especially designed for harsh working conditions, such as conveying sharp and hard materials like coral reefs, weathered rocks, ore, etc. for which ordinary dredging hoses can not withstand for very long. Armored Hoses are suitable for conveying angular, hard and large particles.
Armored Hoses are widely used, mainly in supporting pipeline of dredgers or on the cutter ladder of the Cutter Suction Dredger(CSD). Armored hoses are one of the main products of CDSR.
Armored Hoses are suitable for ambient temperatures ranging from -20℃ to 60℃, and suitable for conveying mixtures of water(or seawater), silt, mud, clay and sand, ranging in specific gravity from 1.0 g/cm³ to 2.3 g/cm³, especially suitable for conveying gravel, flaky weathered rock and coral reefs.

Suction Hose (Rubber Suction Hose / Dredging Hose)
The Suction Hose are mainly applied on the drag arm of the Trailing Suction Hopper Dredger(TSHD) or the cutter ladder of the Cutter Suction Dredger(CSD). Compared with discharge hoses, the suction hoses can withstand negative pressure in addition to positive pressure, and can continuously work under dynamic bending conditions. They are essential rubber hoses for dredgers.

Expansion Joint (Rubber Compensator)
The Expansion Joint is mainly used on the dredgers to the connect the dredge pump and pipeline, and to connect the pipelines on deck. Due to the flexibility of the hose body, it can provide a certain amount of expansion and contraction to compensate the gap between the pipes and facilitate the installation and maintenance of the equipment. The Expansion Joint has a good shock absorption effect during operation and plays a protective role for the equipment.

Bow Blowing Hose Set (for Trailing Suction Hopper Dredger)
The Bow Blowing Hoses Set is an important part of the bow blowing system on Trailing Suction Hopper Dredger(TSHD). It includes a set of flexible hoses connected with the bow blowing system on the TSHD and the floating pipeline. It is composed of a head float, a buoyancy-free hose (Hose A), a tapered floating hose (Hose B) and mainline floating hoses (Hose C and Hose D), with the quick coupling, Bow Blowing Hose Set can quickly be connected to or disconnected from the bow blowing system.

Special Hose (Pre-shaped Elbow Hose / Jet Water Hose)
In addition to regular dredging hoses, CDSR also produces and supplies special hoses such as Pre-shaped Elbow Hose, Jet Water Hose, etc. for specific applications. CDSR is also in the position to supply dredging hoses with customized design.
