PSV & RV SAFETY VALVE TESTING

INSPECTION TESTS OF PSV, RV, POSRV, VB, REGULATORS

1- Online performance tests of PSV - Pressure Safety Valves, RV - Relief Valves, POSRV - Pilot Operated Safety Relief Valves,

2- Offline performance tests of PSV - Pressure Safety Valves, RV - Relief Valves, POSRV - Pilot Operated Safety Relief Valves, VB- Vacuum Breakers, Pressure Regulators,

3- Overhaul, Maintenance, Repair, Renewing of PSV, RV, POSRV, VB, Pressure Regulators,

GENERAL INFORMATION

One of the most critical parts in the plant is Pressure Safety Relief Valves. To prevent these parts very important for Environmental Health and Safety.

Additionally, very important for Reliability, Availability and Preventive & Predictive Maintenance of the Plant. Technical Inspection of pressure vessels and its accessories safety valves, relief valves must be applied annually per local regulations and Local & International Standards.

Technical Inspection of Pressure Vessels and accessories (Pressure Safety / Relief Valves) specified in various standards and regulations. (AD 2000, TS EN ISO 4126-1, TRD, ASME Section I, ASME Section VII, ASME Section VIII, API and National Board).

PSV ON-LINE TEST SYSTEM

On-line test System is approved by Industrial Insurance Companies, International HSE Authorities, ASME, National Board, Lloyds Register, TUV and Hartford Boiler & ASME Authorized Inspectors.

Many of Power Plants, Petrochemical Industries, Refineries, Gas Storage and distribution Industries, Manure Producing Industries, Pipe Lines, Foods Producing Industries Applying ON-LINE TEST System Tests for Safety/relief Valves and certificated.

WORKING PRINCIPLE FOR ON-LINE TEST SYSTEM

A force is applied to the safety valve spindle to overcome the spring tension of the safety valve. This is achieved by using a hydraulic power pack linked to an electronic force transducer. A computer is then used to measure the force applied. By combining this data with the information about the safety valve seat and line pressure of the safety valve it is possible to access the safety valve set pressure.

Portable computer-operated online safety valve test unit to test installed spring-loaded, proportional and full lift safety (relief) valves. The system allows testing of the safety valve, relief valve without taking the safety valve from the installation.

On-line test System could be applied for Steam, Air, Water Process Safety / Relief Valves.

This system only applied to spring system torsion spindles designed Safety / Relief Valves.

Our equipment calibrated and certified by the Turkak-Accredited Traceability Laboratory according to the International Standards.

ADVANTAGES OF ON-LINE TEST SYSTEM

• Reduce Risks and increase Reliability, Availability
• Accurate online diagnose
• Only valves that require an overhaul need to be removed from the plant
• Welded safety valves can be adjusted without costly removal from the line
• No need for temperature correction
• No interruption to plant production during safety valve testing
• Reduced time needed to commission plant after shutdown

SITE APPLICATIONS

• All safety valves visually checked per checklists
• Communicate with the control room and apply On-line test three times.
• Lead seals for tested valves
• Prepare On-line test Certificates that shows test data and graphs for each valve separately signed by TECONT,
• Checklists filled and signed.

ON-LINE TEST APPLYING FIELDS

• Thermal, Hydraulic, and Nuclear Power Plants

• Ships and Gas & Petrol Platforms on the sea.

• Refineries and Petrochemical Plants

• Manure Producing Industries

• Foods Producing Industries

• Perfumery Industries

• Paper Factories

• Textile Industries
