The marine aquaculture cage pipeline is made of special raw materials for seawater corrosion resistance, aging resistance, and high-strength HDPE. It is specially built for deep-sea and offshore aquaculture cage structures. It has excellent seawater immersion resistance, wind and wave impact resistance, high and low temperature resistance, and can be used stably in high-salt, high-humidity, and strong ultraviolet marine environments for a long time.

The pipeline has good toughness, high strength, firm connection, safe and reliable overall structure, no rust, no pollution, no release of harmful substances, and fully meets the requirements of aquaculture safety and environmental protection. Using hot melt butt connection, the interface has high strength, good sealing performance, uniform overall buoyancy, excellent wind and wave resistance, can withstand long-term wave impact and breeding equipment load, long service life and low maintenance cost.

It is widely used in deep-sea aquaculture cages, offshore aquaculture cages, factory aquaculture facilities, aquaculture floating bodies, etc. It is suitable for various aquaculture scenarios such as fish, shrimp, shellfish, etc. It is a special structural pipeline for modern marine aquaculture, deep-water cages, and ecological aquaculture.

• Super resistant to seawater corrosion, suitable for marine high-salt environment

  High-density polyethylene is made of special marine-grade raw materials, resistant to chlorine ions, seawater salt spray, and marine microbial corrosion, and will not age or become embrittled after long-term immersion;

  Comply with GB/T 13663, ISO 4433, ASTM D1693

• Resistant to adhesion of marine organisms, reducing subsequent cleaning and maintenance

  The material is dense and smooth, and oysters, seaweed, etc. are not easy to adhere to, reducing siltation and blockage of marine organisms and ensuring smooth circulation of water bodies;

  Conforms to EN 12573

• High toughness and impact resistance, resistant to wind, waves and impacts from farmed animals

  Elongation at break ≥800%, resistant to wave impact, float collision, fishing raft friction, farmed fish and shrimp impact, and not brittle in low-temperature seas;

  Comply with EN 1046, ISO 13479, GB/T 19472

• The inner wall is smooth and low resistance, and the water circulation efficiency is high

  The inner wall roughness is ≤0.007mm and the water flow resistance is small, which facilitates the exchange of water inside and outside the cage and improves the breeding water environment;

  Comply with ISO 10838, AWWA M55

• Light specific gravity, floatable, easy to install at sea

  The density of the pipe is smaller than that of seawater and can be used for floating operations, which facilitates offshore splicing, layout, and maintenance, and greatly reduces offshore construction costs.

• Excellent flexibility, adaptable to wave deformation and tidal changes

  It is flexible and can be bent moderately, and can be deformed according to tides and wind waves. It is resistant to stretching and breaking, and is suitable for floating cage layouts;

  Comply  with ISO 4427, DVS 2207

• Hot melt integrated connection, reliable sealing at sea and underwater

  Hot melt butt forming, the joint strength is higher than the pipe body, waterproof and seepage-proof, and prevent seawater leakage;

  Complies with DVS 2207, EN 12814

• UV and weather resistant, stable in all-weather marine environments

  Added special anti-UV additives, resistant to strong sunlight, sea breeze, salt spray corrosion, long-term use at sea without powdering and cracking;

  Comply with ASTM F714, GB/T 18252

• Non-toxic and environmentally friendly, ensuring the safety of aquaculture

  Food-grade environmentally friendly material, no harmful substances are released, does not pollute seawater, and does not affect the growth and survival of fish, shrimp, shellfish and algae;

  Comply with GB 4806.7, NSF/ANSI 61

• Super long service life, reducing breeding operation and maintenance costs

  The designed service life of marine aquaculture conditions is ≥50 years, without anti-corrosion maintenance, and is suitable for long-term use in deep-water cages and fish raft aquaculture;

  Comply with GB 50235, AWWA C906
