Dredge ball joint presentation

Ball Joint in General: 

Ball Joint in General Designed by using the latest CAD technologies, production methods and testing facilities in Europe and the Republic of Turkey Designed in six different types, giving variations of tilting angle from 15 to 18 degrees and duties from 10 bar to 30 bar Designed, produced, assembled, tested, painted, greased, packed and transported under close supervision of DREDGE YARD team of engineers and quality control Designed, produced and tested under strict ISO and ASTM standards and double tested at third party for verification

Dredge Ball Joint Types: 

Dredge Ball Joint Types Tilting angle of 15 degrees Low duty for operating pressure of 10 bar Medium duty for operating pressure of 20 bar Heavy duty for operating pressure of 30 bar Tilting angle of 18 degrees Low duty for operating pressure of 10 bar Medium duty for operating pressure of 20 bar Heavy duty for operating pressure of 30 bar

Dredge Ball Joint Features: 

Dredge Ball Joint Features Grease grooves provided in the gland Stiffened dredge ball joint case lugs Quick fix and release locking using a pin and chain connection Pipe welded through the ball Maximum thickness provided at the neck of the ball joint

Dredge Ball Joint Benefits: 

Dredge Ball Joint Benefits Easy assembly and dis-assembly Low maintenance required Low friction between ball and gland due to grease grooves and polished ball and gland face Replaceable liners made from wear resistant materials Quick fix and release of locking

Dredge Ball Joint Materials: 

Dredge Ball Joint Materials Case : cast iron of a manganese alloy providing high elongation and impact value Ball : cast iron of a manganese alloy providing high elongation and impact value Gland : cast iron of a chromium, nickel and molybdenum alloy providing a high tensile high yield and high hardness values Liner : ductile manganese iron or hard chromium iron for wear resistant properties Seal : NBR 70

Dredge Ball Joint Production: 

Dredge Ball Joint Production Production of dredge ball joints is done at high quality and experienced foundry with the latest production facilities to ensure high quality casting and quick delivery time Patterns are made from aluminium or hard wood to ensure that all parts are identical and interchangeable All castings of dredge ball joint are heat treated according ISO and ASTM

Dredge Ball Joint Production: 

Dredge Ball Joint Production All castings are measured and tested before machining All products are measured and tested after machining and before releasing for transport Cast areas are painted and machined surfaces are greased after machining All measurements and tests are recorded at Dredge Yard database

Dredge Ball Joint Quality Control: 

Dredge Ball Joint Quality Control Chemical composition test at third party Mechanical properties test at third party Measurement test of all dimensions after casting Ultra sonic testing for 20% of all surfaces Magnetic particle tests for critical parts

Dredge Ball Joint Quality Control: 

Dredge Ball Joint Quality Control Dye penetrant inspection for critical parts Measurement test of all dimensions after machining Surface roughness test for critical surfaces Hardness test for all parts Assembly test and interchangeable for all parts Locking fix and release test for all dredge ball joints Visual inspection for all parts

Dredge Ball Joint Options: 

Dredge Ball Joint Options Dredge ball joints can be provided with welded pipe and Flange execution Gland liner Ball liner Extra or special lifting lugs Different type of locking Tilting angle up to 22.5 degrees
