2. Hydraulic Properties
Dredge hose is able to withstand pressure up to 1.5 times the normal rated working pressure and still have no signs of leakage. (However, it is advisable not to go over the working pressure limit for operations.)
Hoses can be designed according to buyer’s specific requirements & specifications. The breaking pressure can be designed to go up to 3 times the rated working pressure if desired.
During deformation tests, the variance on length and outer diameter of dredge hoses should not exceed the following data:

3. Vacuum Properties
Even when vacuum pressure goes up to 80kPa, there should be no signs for dismantled layers or physical damage.
4. Adhesive Properties
High quality materials are used. The affinity of adhesives used between layers have a minimum property of 1.5kN/m.
5. Length Variance Tolerance
The length difference tolerance of rubber hose shall be kept within the ±2% of overall length range.
There are some variations of mud suction and discharge hoses depending on usage. Certain reinforced hoses are preferred in some situations. Drop us an email to discuss about what suits your project best.
MAX Floating Dredge Hoses
There are two types of floating hoses available from MAX Groups Marine – flexible and hard (non-flexible).
Flexible inner layer type Floating Hose
Flexible discharge hoses have a flexible inner rubber layer that is of high grade wear-resistant quality.
Hard inner layer type Hose
Hard hoses feature a hard & strong inner layer for operations.
Floating Hoses Features:
- Extremely durable & grind-resistant rubber
- Tensile Strength ≥ 15 MPa
- Wear-out ≤ 0.45cm³/1.61km
- Working Pressure 0.8-3.5 MPa
- Under working operations status, where sand content of substance is less than 30%, the floating part should be not less than 30% of the hose’s largest tubular outer diameter.
- Strong flexural properties performance
Similar to other hose products, reinforced / armored floating hoses are preferred for certain projects depending on project requirements. Different types of flanges and/or collars are available, too.
Equipped with hydraulic tester, vacuum tester and tensile tester, our professional technical staffs are empowered to perform strict performance tests to ensure the quality of our dredge hoses. Leave us an email enquiry so our staff can assist you!
