Quality Assurance inspects the hose assembly before it is proof tested at the assembly validation test rig. Pressure and seal testing of HELIX® hoses is performed at 100%. At the end of testing, Quality Assurance issues the certificate of conformity which is attached to each hose assembly.
To perform proof pressure testing on all the HELIX® hose assemblies, Transfer Oil has installed a 6000 bar (87000 psi) proof pressure test stand. This machine is able to pressurize assembled hoses with a programmable pressure curve.
