Dredge Suction Mouth
Dredge Yard products are designed by using the latest 3D CAD technologies, latest production methods and
testing facilities worldwide. In additional all designs are entirely scrutinized using Finite Element Analysis.
Dredge Yard suction mouth products are designed, produced and tested under strict ISO and ASTM standards
and doubled tested at third party for verification.
All dredge suction mouths are designed, produced, assembled, tested, painted, greased, packed and transported
under close super vision of Dredge Yard team of engineers and quality control. Dredge Yard emphasizes on after
sales and ensures total customer satisfaction.

Dredge suction mouth Materials
According to the customer’s requirements and application in the field the following materials are used:
- Carbon steel: allowing easy welding and hard facing if required
- Carbon manganese steel: to increase the depth of hardening and improving strength and toughness
- Alloy steel: to obtain higher performance in wear resistance

Dredge suction mouth Benefits
- Competitive prices achieved by using one cast piece that eliminates many operations, such as machining, forging and welding
- Casting the dredge suction mouth in one piece allows the most intricate shapes, both external and internal that can be obtained to follow the shape of the flow
- The dredge suction mouth is produced with customized design for anti-wear resistance. More material is added where necessary at high wear areas
- The dredge suciton mouth is produced with high accuracy and precise dimensions to fit in the cutter head and the suction pipe
- The design of the dredge suction mouth is highly adaptable to the requirements of production allowing shorter delivery times

Dredge suction mouth production
The following testing is done during and after production:
- All Dredge suction mouth products are designed according to the customer’s requirements and applications using 3D CAD-technologies
- The design is tested using Final Element Analysis and Dredge Yard experts. External and internal forces are examined and all maximum possible scenarios are simulated.
- Before making the pattern, casting simulation software is run to verify that all thicknesses, curves, radii etc will be obtained and the material will cool down in a good way preventing internal and external shrinkages.
- Patterns are made from aluminum or wood.
- Casting is done in a clean and supervised environment. All necessary measurements are taken to obtain a good casting like using filters, special cast ladles, and strong paint for the mold surface.
- All castings of dredge ball joint are heat treated according ISO and ASTM
- Casting mechanical and chemical properties are verified at third parts.
- After casting and after machining Dredge Yard Team of quality control will inspect all the parts to make sure that the delivery will be according to customer’s and Dredge Yard specifications.
- After approval of the products the cast surface is painted and the machined surfaces are greased.
- Dredge Yard team will supervise the packing and transport to ensure the release of the products in the right way.
