REMOTE FIELD ELECTROMAGNETIC TESTING

Application BOILER - RFET Boiler Water Wall Inspection APPLICATIONS Boiler water wall Inspection Boiler Drum to Drum Tubes Economizer Tubes Super Heater & Re-Heater tubes Furnace Tubes Bare & Coated Piping Insulated piping upto 2” insulation Sphere Legs & Vessel Skirt Heat Exchangers Fin Fan Cooler Tubes Boiler Water Wall Inspection 100% inspection of tubes Travel 40mtr vertically on water wall. Minimum scaffolding is required 5 Tubes can be scanned simultaneously Minimum Cleaning is required Dual frequencies are used 10% wall loss can be detected Equally sensitive to ID and OD defects Real time Inspection can be done Tubular (Boiler & Exchanger) Inspect tubes having ID as small as 0.25” (6.35mm) to tubes of 3” (76.2mm) 60-75% Fill Factor probes can be used for inspection Dual frequency enables to detect defect under Baffle Can differentiate between relevant and non-relevant signal Special Flexible probes for boiler drum to drum inspection

Defects : Fatigue (Thermal) Crack Capacity : 250Mw Material : MAHAGENCO, Bhusawal Defects : Hydrogen damage & Corrosion Pitting Capacity : 250Mw Material : Tube size : Observation : RFET was carried out in selected area around Burners. Localized wall loss like Hydrogen damage, pitting & Bulges were observed. Conclusions : Later the tube were dissected and the given defects were confirmed Tata Power, Jamshedpur Defects : Fatigue (Thermal) Crack Capacity : 250Mw Material : Tube size : Observation : RFET was carried out in selected area around Burners. Severe Indication was observed. No wall was observed. Conclusions : UT scanning was carried out indication reflect the suspect of Thermal (Fatigue) cracking. Later metallurgical test was carried out and it was confirmed that tube has Thermal Cracking

MEW, Kuwait Defects : Bulging Capacity : 250Mw Material : Tube size : Observation : 100% inspection of water wall was carried out using RFET. Localized severe indication were observed. No wall loss was observed and no corrosion or visual defect was observed. Conclusions : Later the tube were inspected using focused high beam light and Bulging were found visually. Later in metallurgical test deformation was confirmed. HPGCL, Yamunanagar, Haryana Defects : Pitting Capacity : 250Mw Material : Tube size : Observation : Inspection carried out on Riffle tube Found Localized Pitting in most of the Tube . Later the tube were cut opened for confirmation and pitting were observed visually. Nearly 250 of tubes were replaced Conclusions : Later the tube were dissected and the given defects were confirmed .

SATURATED LOW FREQUENCY ELECTROMAGNETIC TESTING

Application Tank Floor Scanning - SLOFEC Capability of inspecting ferromagnetic and non-ferromagnetic materials High defect detection sensitivity and reliability Distinction between external and internal defects Detect defect of smooth couture Wall loss of 10% can be detected Works on Coated (8mm) Tank Floor Inspect close to tank wall & weld ie minimum dead zone 25mm High inspection speed (30mtr/min) High inspection temperature range (Piping) Minimum cleaning ie Hydro jetting is required Power Supply: 220 & 110Volts. Can also work with 36Volt power supply Capability of real time scan results with coloured defect mapping Complete C scan of Tank Floor can be given with exact Location, Wall loss & Defect side Internal or External Side rollers for driving along the tank wall LED for visual inspection
