CUSTOMER: British Gas

PROBLEM: The testing of eight, 6’’ x 10” Farris Relief Valves located on vessels containing 202 tonnes of liquid petroleum gas (propane) at the British gas Llandarcy plant in South Wales. In the past the testing of each valve would take 3-4 days.

SOLUTION: A “fingerprint” is taken of each valve in the workshop which is then tested in situ to assess the need for valve overhaul.  The process greatly reduces time on site.

Trevitest is widely accepted by safety authorities and industrial insurance companies in all the key areas of operation including ASME and National Board in the USA, the HSE and Lloyds Industrial Services in the UK and the TUV in Germany. In addition approvals for the Trevitest have been given by many well known companies in the oil, petrochemical, fertilizer, power generation and other process industries.

OUTCOME:  All eight were fully tested in just 16 hours without any interruption to the plant.  The success of this project convinced British Gas to adopt the Trevitest system as part of its ten-year workshop and overhaul procedure.
