ONLINE TESTING OF BOILER SAFETY VALVES.

Amount

Trevi test of Drum & MS Safety Valves: Online Testing (Lifting/Set pressure setting, without actual full floating) of Drum & Main Steam (M.S) line safety valves (i.e. 3 nos per Unit) of our Boilers by TREVITEST / Equivalent test method. You will be offered 3 nos of Safety valves on each occasion (Usually after Annual Overhauling or in case of Short Shut down for Boiler License Extension purpose) for testing. Time is the essence in this testing work, since the Boiler will be kept running on oil firing to maintain a base line pressure of about 85 to 90 % of Lowest set pressure value. The total time period for testing for 3 safety valves should preferably be about 1 hour to 1.5 hour. Make :All valves are of BHEL make, M/S Dresser design (1700 series).

Trevi test of Re-heater Safety Valves: Online testing (Lifting/Set Pressure setting without actual full floating) of CRH & HRH steam line safety valves of our Boilers by TREVITEST / Equivalent method. You will be offered 3 nos of safety valves for test per visit. Line Pressure for all these valves (in full load condition) is about 30 Kg/ cm2. Make :All valves are of BHEL make, M/S Dresser design (1700 series).

Trevi test of Turbine side Safety Valves: Online testing (Lifting/Set Pressure setting without actual full floating) of Turbine side low pr. steam line safety valves by TREVITEST / Equivalent method. You will be offered minimum 3 nos of safety valves for test per visit.
