In dredging operations, the tapered floating hose is the core component of the bow blowing set, and it plays a key role in achieving flexible connection and dynamic transition of the pipeline. With its special structural design and performance advantages, the hose effectively ensures that the floating pipeline maintains stable and uninterrupted transportation operations under complex working conditions.
CDSR tapered floating hose adopts a multi-layer composite structure, consisting of lining, reinforcement, flotation jacket, cover and hose fittings at both ends. Its tapered shape optimizes fluid dynamics and enables it to adapt to the specific needs of floating pipelines by changing the buoyancy distribution.
This hose has a wide range of applicability and is mainly used in locations where bending is required in piping systems. In practical applications, it can be used to connect floating pipelines and underwater pipelines, and can also be used as a connecting hose between the stern pipeline of a cutter suction dredger and the floating pipeline. It is also suitable for the bow blowing set of a trailing suction hopper dredger. This versatility makes it an essential component in dredging operations.
By making full use of the good flexibility and moderate stiffness of the tapered floating hose and slope-adapted hose, a smooth transition between the floating pipeline and the underwater pipeline is successfully achieved in dredging projects. The typical layout scheme adopts a combination of floating pipeline + tapered floating hose + slope-adapted hose + steel pipe + slope-adapted hose + underwater pipeline. During use, the hose set presents a lazy "s" bending shape, and can adjust its bending state to adapt to the water level difference caused by rising tide and falling tide, while ensuring the pipe line is unobstructed. This arrangement has been successfully implemented in many dredging projects in China, proving its reliability and practicality.
In the international dredging field, there is another transitional solution: floating pipeline + full floating hose (SG 2.1) + full floating hose (SG 1.8) + full floating hose (SG 1.6) + full floating hose (SG 1.2) + buoyancy-free hose + underwater pipeline. Although this solution is also feasible, in the current highly competitive market environment, the arrangement using a tapered floating hose has obvious advantages in terms of cost-effectiveness and is a more cost-effective option.
CDSR tapered floating hose has become an important choice in dredging projects at home and abroad due to its excellent performance and economical cost. Its successful application not only reflects the progress in dredging equipment technology in China, but also provides efficient and reliable solutions for the global dredging industry.
