DME Hydraulic Pipe Fittings Control the Salt Spray Test – Redefine Baseline Standards! Up to 1000 Hours of Corrosion Protection

Corrosion is a key issue in extreme marine, mining, industrial and mobile applications, and many other markets, and can cause direct and indirect economic loss. In this regard, we have higher requirements for the corrosion resistance of hydraulic connector fittings.

Comparison of common joints before and after corrosion

Now, after more than 20 years of continuous exploration and development, DME machinery production equipment continuous iteration update, greatly improved the standard corrosion resistance of hydraulic fittings. The product has been upgraded from the original SAE standard of 72 hours for salt spray test to the standard of 400 hours within control, which is the baseline standard of our production.

Our quality inspector is measuring the dimension of hose fittings before test.

However, we did not stop the pace of research and innovation. Recently, we have introduced zinc-nickel plating technology. Compared with SAEJ514 (ISO 9227 method) standard requirements, DME hydraulic fittings can remain up to 1,000 hours in salt spray test without red rust, and have remarkable corrosion resistance.

DME Hose Fitting Salt Spray Test

In order to prove the corrosion resistance of DME connector, we selected DME DABPM107M-2020-ZNNI hydraulic pipe connector, carried out salt spray test under ASTM B117 and ISO 9227 Standard Salt spray test condition, and recorded its change time.

Excellent Corrosion Resistance Advantages

  • Less corrosive, longer durability
  • Reduce spare parts replacement and downtime of host equipment, and improve work efficiency
  • No impact on adjacent parts, low maintenance cost
  • It has higher wear resistance and handling resistance

Many DME hydraulic hose assemblies are displayed.

Of course, DME hydraulic connectors not only have excellent corrosion resistance, but also retain torque value, friction coefficient, pressure grade, color and other key specifications that are important to customers to ensure a more stable hydraulic fluid transport carrier for hydraulic equipment and provide safe and effective connection solutions for your hydraulic system.
