For ‘large-diameter suction and discharge mud rubber hoses’, they can be classified into different types according to actual needs, and the core structure, main specifications, and applicable scenarios of various products all differ. The following table can help quickly understand the characteristics and typical specifications of different types of large-diameter suction and discharge mud rubber hoses:

Feature Type

Large-Diameter Suction and Discharge Mud Rubber Hose (Basic Common Type)
Steel/Flanged Mud Discharge Rubber Hose
Flared Mud Discharge Rubber Hose

Main Features
Reinforced with spiral steel wire, good negative pressure resistance and flexibility
Tube body with steel flange, high strength, wear-resistant, and stable connection
Tube end with flared design, easy installation, and convenient for quick connection

Core Usage
Suction and discharge transportation of media such as silt and slurry in dredging projects
Mud discharge pipelines for dredgers, used in dredging projects (such as channel dredging, port construction)
As pipeline connection hoses in bay and river dredging projects (for transition connection between different pipelines)

Typical Inner Diameter
Multiple specifications from 38mm to 305mm (conventional large-diameter range)
Common φ400mm, φ560mm, φ650mm, φ700mm, etc.
Common φ300mm, φ400mm, φ560mm, φ650mm, etc.

Key Parameters
Number of fabric layers, diameter of spiral steel wire, working pressure
Number of steel cord/nylon cord layers, flange specifications, working pressure
Flared inner diameter and length, tube wall thickness, working pressure

Connection Method
Fitting connection (such as quick connectors, clamp connections)
Flange bolt connection
Flared socket connection (with sealing ring for sealing)

I. Application Scenarios and Manufacturers
Large-diameter suction and discharge mud rubber hoses are key components in dredging projects (such as channel dredging, port construction, river course rectification), mainly accompanying items used with equipment such as dredgers and sand suction ships.

II. Industry Standards and Purchase Suggestions
When purchasing large-diameter suction and discharge mud rubber hoses, you can refer to the chemical industry standard ‘HG/T 2490-1993 Rubber Hoses for Discharge and Suction of Mud’. It should be noted that this standard was abolished in 2012, and it is recommended to query and confirm the currently valid standards through professional channels such as the National Standardization Administration Committee and industry associations.

Since product prices are affected by various factors such as hose type, specification dimensions (inner diameter, length), working pressure grade, material (rubber type, reinforcement layer material), and purchase quantity, and real-time market quotation information is relatively scattered, an exact price range cannot be provided.

If specific application requirements can be informed, such as accompanying items  equipment model, medium characteristics (silt concentration, particle size, etc.), required inner diameter specifications, working pressure requirements, etc., more accurate selection analysis and manufacturer recommendation suggestions can be provided.
