This large-diameter mud suction and discharge hose is a heavy-duty rubber pipeline featuring a multi-layer composite structure, as detailed below: Inner rubber layer: With a thickness ranging from 10 mm to 25 mm, this is the core layer that directly contacts media such as drilling mud and wastewater. It exhibits excellent wear resistance and resistance to acid and alkali corrosion, ensuring a long service life when conveying media containing hard particles like sand and gravel. Reinforcement layer: Typically constructed by braiding or winding high-strength cord, steel wire, or synthetic fibers, it serves as the critical structural component that withstands pressure, ensuring that the hose neither deforms nor ruptures under positive-pressure conveying or negative-pressure suction conditions. Outer rubber layer: Made of wear‑resistant, aging‑resistant rubber, it withstands outdoor exposure to sunlight and rain as well as mechanical abrasion, protecting the hose’s core structure and extending its overall service life. Flanged joints: Both ends of the hose are fitted with steel flanges, with outer diameters ranging from 320 mm to 1090 mm and wall thicknesses from 12 mm to 32 mm. These flanges are rigidly connected via 8 to 32 bolt holes, each with a diameter of 23 mm to 30 mm. This design ensures tight sealing and structural stability, enabling the system to handle high‑flow, high‑pressure fluid transport. Threaded fittings: Certain sizes are equipped with a threaded reinforcement structure ranging from 6 mm to 12 mm in thickness, further enhancing the connection strength between the flange and the hose body and preventing disconnection under high-pressure operating conditions.
Main uses
This product is primarily used in applications that require high‑flow delivery of fluids containing solid particles or corrosive media. Typical use cases include: Dredging operations: In dredging projects for rivers, lakes, and ports, these pipelines are used to suction and discharge sediment and sludge, serving as the core auxiliary piping for dredgers and other dredging equipment. Mines and Power Plants: Used for conveying particle-laden media such as tailings slurry and ash‑water, and can also be employed in coal preparation plants to transport coal‑slurry water. Municipal engineering: Used for emergency drainage, as well as the pumping and removal of wastewater and sludge in urban pipeline network repairs and at sewage treatment plants. Coastal and Port Construction: In dredging and land reclamation operations, it is used for the long-distance transportation of marine sand and mud-water mixtures.
Key Features
The nominal inner diameter ranges from 200 mm to 860 mm, accommodating the flow requirements of projects of varying scales. It is compatible with both positive-pressure conveying and negative-pressure suction, enabling it to handle complex construction environments. Flanged connections facilitate quick installation and removal, making them well-suited for frequent operations at construction sites.
