Our dredge pipeline is available in customizable diameters ranging from 300mm to 1200mm, and working pressures from 0.8MPa to 2.5MPa. We can also customize larger diameters (up to 1500mm) and higher working pressures (up to 3.0MPa) based on your specific project requirements.
Under normal working conditions (conveying high-concentration sand slurry, offshore environment), our dredge pipeline has a service life of 12-18 months, which is 3-4 times longer than the industry average (3-6 months). The service life can be extended to 24 months if used in less harsh conditions.
Yes, our dredge pipeline is designed with a flexible structure and reliable connection joints, making it suitable for ship-to-ship slurry transfer. We can customize the pipeline with floating buoyancy modules to ensure stable floating on the water surface.
Yes, we provide comprehensive installation guidance and technical training for all customers. Our professional technical engineers will be sent to your site to guide the installation process and provide training on operation, daily maintenance, and emergency handling procedures.
Our dredge pipelines have obtained international certifications including CE, ISO 9001:2015, ISO 14001:2015, and ISO 28017. We also provide third-party test reports from SGS, BV, or DNV to meet project acceptance requirements.
