In the fields of marine engineering, dredging operations, CDSR dredging hose has become an important choice in the industry with its unique design and excellent performance. The core products in this series include floating steel pipes, pipe float and tapered floating hoses, each of which has an optimized design for specific application scenarios.
The backbone of efficient transportation
The floating steel pipe is the core product of the CDSR series. It is composed of steel pipe, floating body, outer cover layer and flange fittings at both ends. The main materials of the steel pipe are Q235, Q345, Q355 and more wear-resistant alloy steel. This composite structure gives it many excellent properties:
1.Structural advantages: good rigidity, straight pipe, good flow
2.Wear resistance: Made of high-quality alloy steel, it has good wear resistance
3.Conveying efficiency: small friction coefficient and small conveying resistance
4.Pressure adaptation: wide working pressure range
5.Mechanical strength: strong tensile strength and stiffness
6.Floating characteristics: It has good floating performance and can float on the water surface when working
7.Stability: low center of gravity, good working stability, strong wind and wave resistance
Floating steel pipe is mainly used for floating pipelines, and needs to be connected alternately with rubber hoses to meet the needs of pipeline bending. Its transportation capacity is extremely excellent and can transport various media:
- It can convey a mixture of seawater, fresh water and silt, clay and sand with a specific gravity between 1.0 and 2.0
- It can also be used to transport mixtures of water(or seawater), gravel, flaky weathered rock and coral reef, ranging in specific gravity from 1.0 g/cm³ to 2.3 g/cm³
Cost-effective buoyancy solution
The pipe float is an auxiliary product specially designed to provide buoyancy support. It is composed of steel pipe, floating body, outer cover and retaining rings at both ends. The main materials are Q235, PE foam, NR. Compared with ordinary floats, it has significant advantages:
1.Structural characteristics: good rigidity, straight-through pipeline, easy to install
2.Buoyancy performance: it has good floating performance and can provide large residual buoyancy
3.Durability: excellent weather resistance and strong wind and wave resistance
4.Economical: high utilization rate, can be replaced and reused
The use of the pipe float is very flexible. After being installed on the steel pipe (main mud discharge pipe), it needs to be fixed in the middle to maintain the uniformity and balance of the buoyancy of the steel pipe. One of its major features is its reusability - when the steel pipe used to transport mud and sand is worn and broken, the damaged steel pipe can be removed, the pipe float can be retained and loaded onto a new steel pipe for reuse.
Compared with ordinary PE buoys, pipe floats have better stability, stronger impact resistance and aging resistance, and a much longer service life, making them an ideal, economical and efficient choice for long-term projects.
Experts in flexible connection
The tapered floating hose can adapt to the work needs of dredging water pipelines by changing the distribution of buoyancy. The conventional buoyancy design is SG1.6. Its features include:
1.Protection performance: UV-resistant rubber cover, high wear resistance, with wear indicating color layer
2.Flexibility: good flexibility and large bending angle
3.Strength characteristics: wide range of working pressure, strong tensile strength and stiffness
Tapered floating hoses are mainly used in the parts of pipelines that need to be bent, and have a wide range of application scenarios:
● Used to connect the floating and underwater pipelines
● Used as the stern connection pipe of the cutter suction dredger
● Used as one the bow blowing hoses of the trailing suction hopper dredger
Flexible to use and adaptable to various complex working conditions
Collaborative applications - maximizing efficiency
The three types of CDSR dredging hoses have their own strengths and are often used in collaboration in actual projects to maximize benefits:
1.The floating steel pipe is used as the main conveying pipeline, which undertakes the conveying tasks of most straight sections.
2.The pipe float is used as an auxiliary buoyancy device to ensure the stable floating of the main mud pipe
3.The tapered floating hose plays a key role in the parts that need to be bent
This combined application method not only ensures the transportation efficiency, but also meets the flexibility requirements of complex water operations. At the same time, the reusable characteristics of the pipe float reduce the overall operating costs.
