Hydraulink quality is best demonstrated by the number of end users who specify Hydraulink hose and fittings. These include mine sites, military applications, original equipment manufacturers (OEMs), and a host of industrial end users to name but a few. They rely on performance across the range of service, quality, and application.
Design and Testing
Hydraulink designs, develops and carries out rigorous testing at the company’s facilities. Initial designs are developed in-house and then tested at our research facilities. All fittings supplied by Hydraulink are designed and developed in accordance with relevant international standards. Finite element analysis is an important part of this research.
Hydraulink independently tests hydraulic hose assemblies at our company testing facility. Utilising our BIMAL hose testing machines, hose assembly designs are tested and accredited to the internationally recognised SAE J343 and ISO 6803 specifications. We test assemblies at up to 1000bar (14500psi) and up to 150oc (302F). These pressures and temperature ranges far exceed normal operating parameters. The machines test up 2 inch 6 wire hose assemblies. Tests are carried out by impulsing the hose assembly every second to the specified pressure and then back to zero. The test follows a prescribed wave form which is monitored and recorded on the external computer. This computer collects the data and then produces the test results for certification. Tests vary from 200,000 cycles to 1,000,000 cycles again depending upon the specification. The tests run 24 hours a day and can take up to 12 days continuous testing.
Further testing is carried out using static, leakage, and burst testing parameters for each individual design. Certification is attained following a computer recorded testing program.
We are continually testing hose assemblies as we continue with our own independent research and development. As the market changes new hose types and applications are being developed, and Hydraulink needs to provide a total solution to these. In addition we are also designing new hydraulic hose tails and ferrules to both simplify our range and to provide special designs for OEM customers.
Take a look at our corporate video to see more about our testing programme NZ Corporate Video.
In addition to the above, further testing is carried out on individual hose assemblies prior to supply. These are tested to the relevant specification for a specific application. For example in mining applications, the MDG 41 guideline requests testing in accordance with SAE J343 proof testing.
Manufacturing of Steel and Stainless Steel Fittings
Hydraulink manufacture metal parts (primarily hose tails and adaptors) in a manufacturing plant constructed in 2007. All are manufactured to SAE and DIN specifications under a total quality management system.
This modern facility which employs CNC manufacturing technology, enables production to take place 24 hours 5 days a week and on the Saturday. The factory has two shifts fully manned and the plant runs unmanned in a fully automated role from midnight to 5.00am the next day, when the next shift begins.
The manufacturing plant operates to an ISO based total quality management system. This quality is further enhanced by the latest trivalent plating technology adopted by Hydraulink which offers enhanced corrosion and rust resistance on the fittings.
The vast number of hydraulic applications demands numerous sizes and constructions of hose to satisfy individual working requirements and conditions. Because of this, hydraulic hose varies in weight, size, temperature ratings, numbers and type of reinforcement layers, rated working pressure, flexibility and economics. Our hydraulic hose meets various standards depending upon the selected product being supplied. Some of the standards are:
ABS American Bureau of Shipping
DNV Det Norske Veritas for North Sea Floating Vessels
DOT/FMVSS U.S Department of Transportation / Federal Motor Vehicle Safety Standard
GL Germanischer Lloyds
MSHA U.S. Mine Safety and Health Administration
SAE Society of Automotive Engineers
USCG U.S. Coast Guard
UL Underwriters Laboratory
EN European Norm/Standard
MDG 41 – Mining Design Guideline 41
MDG 41 is an industry based response to the increased number of fluid injection and related injuries being sustained in the mining sector. Mining Design Guideline 41 is a guideline for Fluid Power System Safety at Mines published by the NSW Department of Primary Industry and is now recognised in other states. It is a reference document that should be used when reviewing plant risks in accordance with state Occupational Health & Safety Acts / Regulations. MGD 41 relates to fluid power systems at all mines (open-cut and underground), quarries, dredges, mineral extraction operations and associated plant operating above 5 MPa, (720 Psi) or 60 degrees Celsius. MDG 41 also provides an effective medical protocol to be followed in the event of fluid injection injuries.
Hydraulink products meet/exceed the specifications defined in the MDG 41 guideline and the requirement for a "Matched System". A matched system is defined in MDG 41 'where the hose and fittings (insert/ferrule) are from the same manufacturer and assembled and crimped using the method specified by that manufacturer'. Through our online training and in the field instruction training, we are able to meet the competency requirements defined by MDG 41, both as assemblers and installers of hose and fittings. Hydraulink have a brand new specifically designed hydrostatic testing machine which offers recognised best practice testing to 2 x WP and tagging of hose assemblies (see definition 188.8.131.52 & 3.7.5) ensuring fluid power systems are reliable and fit for purpose. Hydraulink can also show you how to effectively establish your own 'Hose Management' system.
Hydraulink Australia’s new Hydrostatic test machine (shown above) can test hoses, fittings and pipes up to 2410 bar (35,000psi). Our testing regime and subsequent test certificates fully comply with the MDG 41 guideline requirements. Assembly testing is carried out using a computerised data recorder which provides a tamper proof data base for all tested assemblies. Hose labelling is produced in accordance with the MDG 41 guideline requirements and can be tailored individually to suit our customer’s requirements. All tested hose assemblies are uniquely numbered and recorded for the lifespan of the hose.
