Automatic valve test bench was manufactured in L-plan

In Cinkarna Celje, we set up a new valve test bench for automatic testing of ball valves, butterfly valves, control valves and valves actuators, which are manufactured in the Polymers’s section of Cinkarna Celje.

Legaline ATUM-C device allows the following tests:

  1. Measuring the moment of the opening, closing of the ball valve
  2. Leak test of valve seat on both sides. Test medium air, bubble method according to API 527, in accordance with EN 12266-1. With digital laser bubble meter Legaline Bubble Test
  3. Pressure strength test of the housing with water, visual method, pressure drop method.
  4. Leak testing of the spindle with water, visual method, pressure drop method.
  5. Leak testing of hatches, medium air, bubble method according to API 527, in accordance with EN 12266-1
  6. Type test – aging with the method of trimming the valve internal parts by repeatable openings, closings of pneumatic drive.
  7. Testing the functionality of control valves

Pressure relief valves Inspection in Zawia North (General Electric Co.) Libya

With main contractor Intech Company Libya we performed on-line, on-site  Pressure relief valve testing / inspection, during operating in Power plant  Zawia North Combined Cycle Power Plant (General Electric Co.) Libya.

L-plan also implemented the inspection during valves assembly, repair and testing. Setting pressure was determined without pressure in the system by the on-line, on-site testing device Legatest.

Two valves were damaged beyond repair and we are in process to obtain new spare parts from manufacturers soon as possible.

Together with our partner company Intech,  the doors are opened to work in all thermal power plants in association with General Electric Co. Libya .

Online pneumatic control unit & safety valves testing-measurement device Legaline CSPRS

L-plan successfully ended the development and production of new high accuracy testing device – Legaline CSPRS.

With new device all types of Pneumatic control unit devices (Pneumatic  Supplementary  Loading  Systems) can be tested on-line, on-site, during operation.

Pneumatic control unit as same as spring loaded safety valves testing is performed according to standard EN ISO 4126-5-2013; Testing of safety valves for protection against excessive pressure – Controlled safety pressure relief systems – CSPRS.

While the test is performed the following pressure versus time values (curves) are displayed simultaneously:
– System pressure
– Pressure of compressed air fed in the control box
– Air pressure in the upper chamber of pneum. piston
– Air pressure in the lower chamber of pneum. piston
– Spindle lift of the safety valve
– Sound phenomena associated with the opening of the safety valve may be displayed.

After completion of the development of device for testing the pneumatic units for controlled pressure relief systems Legaline CSPRS, we  successfully conducted tests of pneumatic units for controlled opening and closing of safety valves in the following companies:

  • EVONIK Röhm GmbH Germany
  • TOTAL Raffinerie Mitteldeutschland GmbH, Leuna
  • SES Kardia PPC Greece
