According to the structural diagram, the flanged dredging hose is a multi-layer composite rubber hose that, from the innermost layer to the outermost layer, primarily comprises: Inner rubber layer: Directly conveys media such as sand and slurry, utilizing wear‑resistant, chemically corrosion‑resistant rubber to ensure smooth flow of the conveyed medium. Intermediate Rubber Layer and Reinforcement Layer: This layer comprises radial reinforcement, localized reinforcement, and specialized skeletal materials, utilizing high-strength fiber fabrics or steel wires as the reinforcing framework to ensure the pipe’s pressure-bearing capacity and tensile strength, thereby preventing deformation or rupture. Outer rubber layer: Made of wear‑resistant, aging‑resistant rubber to protect the internal structure from seawater, sand and gravel, and ultraviolet radiation, thereby extending service life. Metal flanges and metallic strip reinforcement: Both ends are fitted with metal flanges for quick connection to other pipelines or equipment; a metallic strip is embedded on the exterior of the pipe body to enhance its rigidity and resistance to torsion.
Main uses
1. Core conveying for dredging projects: Widely used in port and navigation channel dredging, riverbed excavation, land reclamation, and other engineering applications, it is employed to transport high-concentration mixtures of sediment, slurry, and gravel. 2. Marine and Inland Water Environment Compatibility: The flexible pipe body mitigates pipeline oscillations caused by waves and currents, reducing impact forces on connection joints and ensuring stable operation in complex aquatic environments. 3. Equipment Integration: Designed for use with dredgers, mud pumps, and other equipment, it features quick flange‑type connections to enable efficient loading, unloading, and media transfer, thereby enhancing dredging productivity. Can be custom-made according to user requirements.

Factory workshop
Jiuxing Rubber & Plastic is a 100% manufacturing enterprise specializing in hydraulic hoses and industrial hoses, covering all fields including oil and gas, agriculture, transportation, construction, mining and forestry.
Laboratory
Our factory has introduced a complete set of laboratory testing equipment. We possess advanced laboratory capabilities and can conduct product quality inspections and research and development work to ensure stable and excellent product quality.
After purchasing raw materials, we will test each batch to ensure it meets the technical requirements of our products.
After production is completed, we will test each hose, including its working pressure and burst pressure, and conduct pulse tests for each order to ensure 100% qualification of the factory-finished products.
We strive to provide customers with top-quality hoses and do everything possible to ensure their quality.
Product packaging and transportation
I. Order Confirmation
After the order is placed, the customer service and the business team will immediately verify the product specifications, quantity, delivery date, and special requirements. After production is completed, a full inspection will be conducted to ensure that the size, performance, and appearance meet the standards. Only after passing the inspection can it proceed to the packaging stage.
II. Professional Packaging
According to the customer's requirements, the hydraulic hoses will be packed in cardboard boxes or wooden boxes. After the hoses are produced, we will pack them. Usually, woven bags and plastic films are used for packaging. Special packaging can be provided according to the customer's requirements. Special packaging is the requirement of the Edible ACC Ording customers.
III. Loading and Transportation
The professional loading and unloading team will operate in a standardized manner, load and unload gently, and stack reasonably to ensure the stability of the goods. Support domestic full truckload/less-than-truckload logistics, international sea freight, air freight, express delivery and designated freight forwarder transportation. The entire process is securely fixed to avoid squeezing， collision， and tipping， suitable for long-distance transportation.
IV. Tracking & Delivery - Goods Tracking and Delivery
After shipment, provide the full set of documents including the logistics tracking number / bill of lading / packing list, invoice, etc. Real-time follow-up of the logistics status, timely synchronization with the customer to ensure safe and punctual delivery. Support various trade terms such as FOB, CIF, CFR, etc., and provide a worry-free connection throughout the process.
V. Payment Method:
Order ≤ $10,000: 100% wire transfer for advance payment Order > $10,000: 30% wire transfer for advance payment, and settle the balance payment before shipment Support wire transfer (T/T) and letter of credit (L/C)
