Pipeline systems are an integral part of industrial and municipal infrastructure, transporting a variety of liquids and gases. An important consideration when selecting pipe material and design is whether to use a liner. A liner is a material added to the inside of a pipe to protect it from corrosion, abrasion, and other damage. While unlined pipes may be more economical in terms of initial investment, they often come with higher maintenance costs and potential replacement costs in the long run.
Corrosion and wear issues
Unlined pipes are more susceptible to corrosion and abrasion. When conveying corrosive media, unlined metal pipes will gradually corrode, resulting in a reduction in wall thickness and possible leakage. In addition, when conveying fluids containing solid particles, the inner wall of the unlined pipe will be worn, which will also reduce the service life of the pipe.
Maintenance and repair costs
Because unlined pipes are more susceptible to damage, they require more frequent inspections and maintenance. This includes regular internal inspections to detect the extent of corrosion and wear, and carrying out necessary repair work. These maintenance activities are not only time-consuming but also costly.
Replacement and downtime losses
Once unlined pipe fails due to corrosion or wear, it must be replaced. Replacement work often involves downtime, which results in interrupted production and lost revenue. Additionally, the cost of replacing the pipe is often much higher than the cost of initially installing the lined pipe.
Environmental and social impacts
Leakage in unlined pipes not only leads to economic losses, but may also cause serious environmental pollution. For example, oil or chemical spills can contaminate water supplies, affect ecosystems, and even threaten human health. These environmental and social impacts may result in additional legal proceedings and compensation costs.
Advances in lining technology
With the development of technology, lining materials and application techniques are also constantly improving. Modern lining materials such as polymers, ceramics and composites offer improved corrosion and wear resistance, significantly extending the service life of pipelines. These technological advances make the initial investment in lined pipe more reasonable and the long-term benefits more obvious.
The application of lining technology in pipeline systems not only improves the durability and safety of pipelines, but also significantly reduces long-term maintenance and replacement costs. Especially in the field of dredging engineering, the dredging hoses designed by CDSR further optimize energy efficiency and operating performance through advanced lining technology, and meet the needs of various complex engineering environments.
