Core Difference Comparison

Design Focus

Ordinary Dredging Rubber Hose：The tube body is uniformly pressure-bearing overall

End Dredging Rubber Hose:While maintaining the strength of the tube body, the connection ends are specially reinforced to withstand local stress.

End Structure Characteristics

Ordinary Dredging Rubber Hose：A standard structure may be adopted

End Dredging Rubber Hose:Adopt special enhanced processes. For example, the ‘flange end face wear-resistant rubber flange composite process’ integrates the end face wear-resistant layer with the inner layer of the pipe into one body.

Key Performance Advantages

Ordinary Dredging Rubber Hose：Overall performance is balanced, suitable for general wear environments.

End Dredging Rubber Hose: Significantly improve the wear resistance, pressure resistance, and cavitation resistance at the end, solve the ‘weakest link effect’ at the flange connection, and extend the overall service life by 10 times

Applicable operating conditions

Ordinary Dredging Rubber Hose：Conventional sediment and sludge conveying

End Dredging Rubber Hose: More suitable for complex operating conditions, large pressure fluctuations, and environments with impact-prone media (such as conveying gravel, coral reefs, etc.)

💡 How to get more accurate information?

Since the specific materials, number of layers, and process details of the pressure layer belong to the core technology of the product, they are hard to find through public channels. If you need accurate information, it is recommended to take the following approaches:

1. Consult the manufacturer directly: This is the most direct and reliable way. You can contact professional dredging pipe manufacturers.Ask them for the technical manual of the specific product or consult the technical specifications directly.

2.Check the latest industry standards: Understanding industry standards helps you grasp the overall technical requirements. The relevant standard is HG/T 2490-2023 ‘Rubber Hoses and Hose Assemblies for Dredging – Steel or Fabric Reinforced – Specification’ , which has been implemented since February 2024 and replaces the old HG/T 2490-2011. However, the standard mainly stipulates general requirements and does not include specific details about end reinforcement.

3.Pay attention to patent information: Many innovative end structure designs are patented. You can try searching relevant keywords (such as ‘dredging rubber hose’, ‘end reinforcement’, ‘flange connection’) in patent databases, which are often the best publicly available source for detailed technical solutions .

Hope this information can provide you with valuable references. If you need help finding information about specific manufacturers or models, please let me know more details, and I would be happy to continue assisting.
