NDTs allow for the evaluation and assurance of optimal tank conditions during deployment, repair, and industrial maintenance.
NDTs ensure that a storage tank meets safe and operational conditions before being put into operation.
Technique for revealing surface flaws in solid materials by visual contrast of penetrant and developer.

Acoustic Emission (EA) is a Non Destructive Testing (NDT) method, based on a physical phenomenon that takes place inside materials. It is defined as the spontaneous energy emitted by a material, in the form of transient elastic waves. They constitute a method applied to detect and locate leaks and defects such as cracks or corrosion in pressure equipment, machines, installations, cranes, bridges, etc. The advantage of the method is that defects can be recorded before they become problems.
Summary of the steps for qualifying and certifying NDT personnel under ISO 9712 and SNT-TC-1A.
Inspection of storage tanks according to American Petroleum Institute (API) standards are important to prevent not only catastrophic failures, but also to avoid problems related to the mechanical integrity of the assets affected mainly by corrosion in floors, walls and ceilings.
The field of storage tank inspections comprises in-service and out-of-service inspections of vertical and horizontal above-ground and subway tanks. A combination of techniques including engineering calculations according to API 653 and API 650 and other relevant specifications are used to perform a comprehensive inspection of the overall condition of the tank.

Visual inspection is a simple test compared to other non-destructive testing methods; however, since the main tool for carrying out this activity is the human eye, various factors can affect the sense of sight and distort the observation of surface imperfections.
