Servo-hydraulic test systems use controlled hydraulic power to apply precise static and cyclic loads to materials, components and structures. These systems are used for applications such as fatigue, durability, fracture, tensile, compression and bending testing, where accurate and repeatable hydraulic performance is essential.
The hydraulic circuit connecting the power unit, manifolds, servo valves and actuators must therefore provide reliable fluid delivery under demanding pressure, flow and cyclic operating conditions.
Servo-hydraulic test systems continuously control hydraulic pressure and flow to drive actuators through precise loading cycles. This places demanding requirements on the piping and connections supplying the system, particularly where hydraulic fluid is routed between the power unit, manifolds, servo valves and actuators.
The piping may be subjected to high pressure, pressure fluctuations, vibration and repeated dynamic loading. Any leakage, restriction or failure in the hydraulic circuit can affect system performance, interrupt testing and potentially damage sensitive hydraulic components.
The challenge becomes greater as test systems become larger or more complex. Multiple actuators, distribution manifolds and hydraulic circuits can require extensive piping routed through a compact test facility, where accessibility for conventional fabrication and maintenance may be limited.
The piping system therefore needs to provide secure, leak-tight connections while allowing the hydraulic circuit to be installed, maintained and modified efficiently.
Servo-hydraulic test systems require piping connections that can withstand high hydraulic pressures, vibration and repeated pressure cycles while maintaining reliable sealing throughout testing.
Cenergy provides specialised non-welded flange connection solutions for hydraulic piping, allowing pipe connections to be assembled without conventional welding while providing a robust connection between pipes, valves, manifolds, actuators and other hydraulic components.
The 37° Flare Flange System provides a compact, reliable connection for hydraulic piping where space, accessibility and leak-tight performance are important.
The pipe is mechanically flared to create the sealing surface, eliminating the need for welding while providing a secure connection suitable for hydraulic applications.
Key advantages:
The Retain Ring Flange System provides a robust flanged connection for hydraulic piping, particularly where higher mechanical loads and secure pipe retention are required.
The system uses a retain ring to mechanically secure the pipe to the flange, creating a strong connection without welding the pipe to the flange.
Key advantages:
For servo-hydraulic test systems, eliminating welding from the piping installation can simplify fabrication and reduce the need for welding equipment, post-weld finishing and inspection. More importantly, it allows the hydraulic piping to be assembled using a controlled mechanical joining process while maintaining the flexibility required around complex test equipment.
Cenergy can provide the appropriate flange connection technology based on the pipe size, pressure, layout and requirements of the test system.
The 37° Flare Flange and Retain Ring Flange systems provide non-welded alternatives for connecting hydraulic piping in servo-hydraulic test systems. They help simplify fabrication and installation while providing robust connections for demanding hydraulic service.
TMI’s hydraulic flange systems can be used across different sections of a servo-hydraulic test circuit, depending on the pressure, pipe size, connection type and system configuration.
