The safety valves maintenance were done by L-plan personnel in Powerplant Duisburg Germany. L-plan Inspection body implemented also on-site safety valves testing with the Legatest device.
At the same period, we tested pneumatic control units with new, in L-plan developed and manufactured Legaline CSPRS device for client Raffinerie Leuna Germany.
