Comprehensive fatigue test bench for deep-sea environmental simulation of oil pipelines

Main applications:

The test system is used to simulate the internal and external alternating stress existing in the service of full-size sea pipes, and to carry out static and dynamic fatigue tests of internal pressure and bending of full-size oil, gas and water pipelines, so as to realize individual or coordinated loading tests.

Product overview:

The test system is used to simulate the internal and external alternating stress existing in the service of full-size sea pipes, and to carry out static and dynamic fatigue tests of internal pressure and bending of full-size oil, gas and water pipelines, so as to realize individual or coordinated loading tests.

Technical advantages:

1. Multi-channel independent or coordinated loading;

2. Adopt international leading digital PID control system;

3. The base adopts the patented TPHS structure with high stiffness and no deformation in long-term operation;

4. (low hydraulic pressure, over temperature, filter plug, overload, etc.) intelligent protection.
