NDT TESTING, INSPECTION AND RE-CERTIFICATION OF 2 X 300 MT MOUNDED BULLETS AND 2 X 15 MT LPG

Mounded Bullets

To conduct the Visual examination ASME Sec.V Art. 28 of internal surfaces for observation on any surface defects, weld defects, corrosion, pitting or otherwise physical and material defects etc.

To conduct the Ultrasonic thickness measurement as per ASTM-E-797 on shell plates and dished end plates, Nozzles as per the SMPV rule & ASTM A577-88 or Equivalent code. Mapping of each plate to cover the whole plate 6 to 7 readings to be taken between each consecutive weld seam and record Minimum thickness observed, Original Thickness, Nominal plate thickness, Minimum calculated thickness (without C.A.) and Residual Corrosion Allowance etc.

Wet fluorescent magnetic particle test of welds using AC Yoke – magnaflux / tiede / Y6 black light and white washable distemper as background and as per applicable codes (Refer ASTM-E-709/ASME Sec. V) . Internal 100% (all weld joints from inside), nozzle welds (internal & external).

To conduct 25% ultra flaw detection (width of scanning 50 mm) of welds from inside the bullet as per ASTM-A- 577 & as applicable codes including T-joints. (Refer ASME.Sec.V, Article 4 except that for thickness 2" or less, calibration blocks described in Fig. T-434.2.1 shall be used) Not less than 25% of weld seams including all T. joints middle circumferential seams, Bottom & Crown weld seams

To conduct Dye penetration test at all accessible areas and as per ASTM-E165/IS:3658 or applicable codes using krautrammer Microdour or Equotip type (Poldi type not to be used) portable tester.

To witness Hydraulic testing as per SMPV rules and issuance of test certificate as per the applicable code.

To Check the Healthiness of Cathodic Protection system

To check operational fitness of ROV's and Flow measurement of Excess Flow Check valves

Certificate & documentation: To submit 5 sets of testing & inspection certificates/ test reports & documents for all tests and inspections covered in the scope of work as per SMPV rule no.19 & revelant factories act as applicable.
