Safety Valves Tests

  1. INTRODUCTION:

Our company performing Online Pressure Safety / Relief Valve Functional Tests with On-line test System and adjustment if required while plant in service.  

With this On-line test action, plants reliability and availability will increase and risks decreases. Our company performs this On-line test of safety valves relief valves service per local and international standards.

  1. TECHNICAL INSPECTION OF PRESSURE VESSELS, SAFETY VALVES AND LOCAL & INTERNATIONAL STANDARDS.

One of the most critical parts in the plant is Pressure Safety Relief Valves. To prevent this 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.

(See. Local Legislation;

Basinçlı ekipmanlar yönetmeliği, İş ekipmanlarının kullanımında sağlık ve güvenlik şartları yönetmeliği (97/23/AT) 25.04.2013 tarihli ve 28628 sayılı Resmi Gazete), TS 2025


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).

Pressure Relief Devices Performance Test Codes specified in ASME PTC 25 Standard.

  1. 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.

  1. 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 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 on spring system torsion spindles designed Safety / Relief Valves.

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

  1. 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 plant
  • Welded in 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
  1. SITE APPLICATIONS

  • All safety valves visually checked per checklists
  • Communicate with 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.
  1. 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

  • Central heating plants

  • All industries that Pressure Vessels existing
