Hydraulic test bench
Our hydraulic test bench allows us to perform pressure testing of tensioners after repair at up to 1500 bar / 21,750 psi. We always ensure that a visual inspection of the hydraulic hoses and couplings is carried out, followed by pressure testing.
In addition, we perform tests on chemical hoses from power plants – in accordance with applicable regulations. These tests include full traceability and are concluded with the issuance of a test certificate.
