Dredge Yard launches various dredge pipe pieces


Dredge Yard, a company based in the Netherlands and United Arab Emirates, provider of latest dredging technology and equipment, is proud to announce the launch of complete line of dredge pipe pieces.
The dredge pipe pieces are used on board of dredgers to connect the dredge pump with the discharge pipe.
Dredge Yard specialists designed the dredge pipe pieces in different variety and different thicknesses in order to meet customers’ requirements, to provide them the best proper solution and the lowest costs.
The dredge pipe pieces provided as Bend Pipe, T-Pipe, Pitched T-Pipe,Y-Pipe, Cross Pipe, Strait Pipe, and Conical Pipe are produced at high quality and experienced foundry with the latest production facilities to ensure a very high quality of casting and a quick delivery time. 
Flanges of the dredge pipe pieces are cast together with the pipe aiming to give a strong connection. Others feature of the dredge pipe pieces are the lifting lugs making them easily for handling. During production more attention is paid to smoothen the inner surface of the dredge pipe pieces in order to lower the friction loses. Also all dredge pipe pieces are designed in such a way that their shapes and curves follow the flow pattern to lower friction losses and avoid vortexes.
Dredge Yard offers dredge pipe pieces according to customers’ applications and requirement in different materials like manganese alloy that is providing high elongation and impact value and high chromium, nickel and molybdenum alloy that is providing high tensile, high yield and high hardness values. 
All castings of dredge pipe pieces are heat treated according ISO and ASTM standards and all the products are measured and tested before machining, after machining and before releasing for transport. All these measurements and tests are recorded at Dredge Yard database.
Dredge Yard official site, www.dredgeyard.com, can provide further information relative to dredge pipe pieces and about all the dredging equipment and technology.
Dredge Yard emphasizes on after sales and ensures total customer satisfaction delivering dredge related products with a high ratio of reliability and value for money.

Wide range of dredge ball joints introduced by Dredge Yard

Dredge Yard, the provider and manufacturer of dredging equipment, has now introduced a very wide range of dredge ball joints for its customers.


In order to provide customer with the best suitable solution and lowest cost, Dredge Yard specialists designed the dredge ball joints in 6 different types, giving variations of tilting angle from 15 to 18 degrees and duties for operating from 10 bar to 30 bar. All the details about the sizes can be found on Dredge Yard site www.dredgeyard.com.
The materials used for the production depends on each part of the dredge ball joints. Because the case and the ball need a high elongation and impact value, cast iron of a manganese alloy is used. The material needs for the gland are cast iron of a chromium, nickel and molybdenum alloy that provides a high tensile strength, high yield point and high hardness values. For wear resistant properties of the liner, ductile manganese iron or hard chromium iron is used.

The production of dredge ball joints is done at a high quality and experienced foundry with the latest production facilities to ensure high quality casting and quick delivery time. To ensure that all parts are identical and interchangeable, the patterns are made from aluminum or hard wood. All castings of dredge ball joint are heat treated according to ISO and ASTM standards and they are measured and tested before machining. After machining and before releasing for the transport, all the products are measured and tested again.
During and after production all products undergo a systematically testing including chemical composition and mechanical properties test, measurement test of all dimensions after casting, ultra sonic test, magnetic particle test, surface roughness test and dye penetrant inspection for critical parts, measurement test of all dimensions after machining, hardness test, assembly and interchange ability test, and visual inspection for all parts.

Dredge Yard management has related that: "All measurements and tests are recorded in our database and our customers are welcome to witness any test in our production facilities". Dredge Yard also offers the opportunity of choosing additional options for the production of dredge ball joint as they can be provided with welded pipe and flange execution, with gland liner, ball liner, extra or special lifting lungs or only with different type of locking.

This wide range of dredge ball joints bring a lot of benefits such as easy assembly or dis-assembly, low required maintenance, quick fix and release of locking. The replaceable liners are made from wear resistant materials and there is a very low friction between ball and gland due to grease grooves and polished ball and gland face.
All dredge ball joints 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 delivering dredge related products with a high ratio of reliability and value for money.

DREDGE YARD - Extending life time of dredge components using FEA

DREDGE YARD’s components and equipment are designed using FEA in order to optimize the design and ensure low stress forces in the material. In this way the life time of the equipment is increased and the cost price is reduced.
By the late 70’s, FEA – Finite Element Analysis was limited owned by the aeronautics, defence, nuclear and automotive industries. Later, due to a impressive increase in computing power and a drop in the cost of computers, FEA was technologically advance to a very high accuracy.
Nowadays, the computers have the capability to give precise results for all type of parameters.
FEA – Finite Element Analysis is one of the most dominant numerical methods used to check how the structure will react to certain loading conditions.
Theoretically speaking, FEA is using a system of points called nodes that together create a grid called mesh. The mesh contains the material and structural properties that shows how the structure will react to certain loading conditions. Depending on the stress levels anticipated of a particular area, the nodes are assigned at a certain density all over the material. Generally a higher node density will be found in the areas that will receive large amounts of stress. The areas that will receive little or no stress it will usually have a lower node density. So, FEM provide detailed visualization of where structures twist or bend and gives precise indications of the distribution of stresses and displacements.
DREDGE YARD related: ’’All our components are tested in Finite Element Analysis as one part after that all parts are assembled and tested under pressure and maximum movements. Worst case scenarios are simulated and pick loads are applied. After analysis, the design might be reviewed couple of time to find out the most optimal shape and lowest stress in material. For wear parts, a Finite Element Analysis is run for worn out parts as well allowing our engineers to design the dredging components for the longest life time by adding material where necessary.’’  
In summary, FEA’s benefits include enlarged accuracy, intensified design and enhanced perception into critical design parameters, virtual prototyping, amplified productivity and increased revenue.
