With the growing global demand for marine resources, marine aquaculture and fisheries have become an essential part of the food supply chain. These sectors operate under complex environmental conditions, which place stringent demands on equipment performance, particularly for water transport and drainage systems. Against this backdrop, PVC layflat hoses have emerged as a vital tool in these industries due to their excellent performance and cost-effectiveness.

PVC layflat hoses are made from polyvinyl chloride (PVC) material, often reinforced with fibers or high-strength components. This unique structural design endows them with corrosion resistance, high flexibility, and ease of use. The marine aquaculture and fisheries environments are highly corrosive due to the presence of salt and chemicals, yet PVC materials exhibit exceptional resistance to salt and alkali components in seawater, maintaining stable performance over the long term. Additionally, the layflat design allows the hose to be easily rolled up after use for convenient transportation and storage. The smooth inner wall reduces fluid resistance, further enhancing efficiency in water transportation. These characteristics make PVC layflat hoses well-suited for a variety of marine operations.

In marine aquaculture, PVC layflat hoses are widely used in seawater transport and circulation systems. Farms need to introduce clean seawater from the deep sea into cages or tanks to ensure adequate dissolved oxygen levels, which are essential for the healthy growth of fish and shellfish. At the same time, wastewater generated during aquaculture must be discharged promptly to prevent pollution. PVC layflat hoses demonstrate excellent performance in these transportation and drainage tasks due to their corrosion resistance and pressure-bearing capacity. Furthermore, PVC layflat hoses are crucial for feed delivery in aquaculture. Their smooth inner walls help avoid feed accumulation or blockages, ensuring a smooth and efficient delivery process. During extreme weather or emergencies, aquaculture facilities may face risks of waterlogging and contamination. In such cases, PVC layflat hoses can be quickly deployed to assist in emergency drainage, mitigating potential losses.

In the fisheries sector, PVC layflat hoses also have widespread applications. During fishing operations, boats and fishing equipment require frequent cleaning, which demands an efficient wastewater drainage system. PVC layflat hoses can withstand high flow rates and frequent bending, making them ideal for such high-intensity use. During live fish transportation, maintaining water stability and oxygen levels is critical. PVC layflat hoses can connect to oxygenation equipment or facilitate water exchange, significantly improving the survival rate of fish. Additionally, in fishing port facilities, PVC layflat hoses are often used for water drainage and waste management. Fishing ports are exposed to seawater and sunlight, requiring equipment with excellent salt and UV resistance. PVC layflat hoses fully meet these demands.

The widespread application of PVC layflat hoses in marine aquaculture and fisheries is attributed to their numerous advantages. First is their economic efficiency. PVC layflat hoses have relatively low production costs but offer performance comparable to traditional rubber or metal hoses, making them ideal for small- and medium-sized enterprises. Second, they have a long service life. PVC materials are highly weather-resistant and can withstand harsh environments, reducing the frequency of equipment replacement and maintenance costs. Additionally, the layflat design not only facilitates storage but also simplifies inspection and maintenance, making leak repairs more straightforward. Lastly, with growing environmental awareness, the partial recyclability of PVC materials makes these hoses a more sustainable choice.

The performance of PVC layflat hoses in real-world applications is impressive. For example, in a large deep-sea aquaculture project, PVC layflat hoses were used for water circulation and transportation, significantly enhancing water quality management with their corrosion resistance and weather durability. In a coastal fishing port drainage system upgrade project, PVC layflat hoses improved the port’s operational stability due to their exceptional durability and convenient maintenance. These cases fully demonstrate the adaptability and value of PVC layflat hoses in marine environments.
