In order to provide customers with the most suitable solution and lowest cost, Dredge Yard has designed the ball joints in six different types, giving variations of tilting angle from 15-18 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 company explained. "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 are used."
The ball joints are produced at a high quality, 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 aluminium or wood. All castings 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 systematic testing," said the company.
Dredge Yard said customers are welcome to witness tests at its production facilities. Dredge Yard also offers customers the opportunity to choose additional options for the production of dredge ball joint - 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 maintenance, quick fix and release of locking," said Dredge Yard. "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.
