In high-pressure hydraulic systems, the force of the fluid is immense, often reaching thousands or even tens of thousands of pounds per square inch (PSI). In such a demanding environment, a small defect at any connection point can lead to catastrophic failure. Therefore, in high-pressure applications, hydraulic hose fittings are not just connectors; they are the ultimate guardians of system safety, efficiency, and continuous operational capability.
High-pressure environments demand that fitting materials possess outstanding yield strength and fatigue resistance. Duoli's high-pressure hydraulic hose fittings series, specifically designed for sectors such as mining, heavy construction, and marine drilling, typically utilize high-strength alloy steel that has undergone special heat treatment.
Our design strategy includes employing multi-thread and deep-thread structures to distribute stress and prevent thread slippage. Furthermore, the body thickness of our fittings is optimized to ensure geometric stability when subjected to extreme pressure impulses and continuous high pressure, completely eliminating the risk of rupture.
In high-pressure equipment such as excavators, hydraulic breakers, and hydraulic presses, pressure is not constant but is filled with severe impulses and high-frequency vibrations. These dynamic loads can accelerate the fatigue failure of ordinary fittings. Duoli's high-pressure hydraulic hose fittings are specifically optimized to counteract these challenges.
We employ a unique inner tube design and crimping specifications to ensure a smooth and secure transition between the fitting and the hose inner layer, effectively absorbing and dissipating the energy generated by pressure impulses. In addition, the surface treatments on the fittings (such as high corrosion-resistant plating) not only extend their resistance to harsh environments but also enhance their mechanical wear resistance during repeated connection and disconnection.
The application demands in high-pressure environments are diverse, ranging from ultra-high-pressure cleaning equipment to deep-sea remotely operated vehicles. Duoli recognizes the limitations of one-size-fits-all solutions and thus provides a comprehensive customization service for high-pressure hydraulic hose fittings.
Whether a client requires specific flange connections, corrosion-resistant stainless steel materials, or specialized sealing materials capable of withstanding extreme temperatures, Duoli can provide tailored fitting solutions based on actual working pressure, fluid type, and environmental conditions. Choosing Duoli means choosing a reliable partner that guarantees system performance and personnel safety in the most dangerous and demanding high-pressure applications.
