Complete inspection following API-653 Out-of Service inspection checklist. Minimum of three thickness readings per each course per drop. Minimum of five thickness readings per each full roof plate. Minimum of five thickness readings per each full bottom plate. Vacuum box testing of all bottom lap welds and shell to bottom welds (corner welds). Magnetic particle test nozzle welds and bottom-to-shell weld (or corner box) if tank is properly prepared. Visual inspection with photographs and/or record of any visible defects. Thickness reading for all accessible nozzles. Shell layout drawings. Roof layout drawings. Bottom layout drawings. Nozzle layout drawings. Bottom settlement survey. Post inspection meeting to discuss findings. Recommendations and/or observations. Summary of inspection findings. Final formal report.

In an effort to provide our clients with the most accurate data possible about their tanks, DJA Inspection Services incorporates MFL (Magnetic Flux Leakage Evaluation) tank floor scanners. Our scanners use the principle of magnetic flux leakage to detect topside and underside pitting of steel tank bottoms.

Component failure? Now what? When there is a failure of a piece of equipment or component, a failure investigation takes place. If you are driving down the road and a tire on your vehicle goes flat, you make a failure investigation. The tire may have a nail in it, the valve stem may be damaged, and the tire may be demolished. Upon completing the investigation you then know what to do. You may decide to fix the tire or replace it. A complete investigation though may look to see where the problem originated. The tire failure may have been a manufacturer`s defect or your neighbor may be having his roof replaced and there are nails on the street. As the complexity of the investigation is increased the level of expertise raises as well.

DJA Inspection Services offers a complete piping inspection service per API Standard 570 which covers the In-service inspection, rating, repair, alteration procedures for metallic and fiberglass-reinforced plastic piping systems. API 570 provides the requirements for maintaining the integrity of piping systems after they have been placed in service. Our certified inspectors and engineers work as a team to provide quality, comprehensive inspections.

The word laser is derived from the acronym for Light Amplification by Stimulated Emission Radiation (LASER). Lasers are defined as devices that generate intense beams of coherent (having a constant phase of difference between waves), monochromatic light or other electromagnetic radiation by stimulaed emission of photons from excited atoms or molecules. 

DJA Inspection Services, Inc. also offers Helium Mass Spectrometer Leak Testing (MSLT).  MSLT can be used to help provide assurance that your tank bottom is liquid tight before returning to service. HMSLT is a trace gas leak detection system that uses helium. This gas has a very small molecular structure and can leak from the smallest leak path in any vessel or piping system.
