Non-Destructive Testing (NDT) is a crucial aspect of the manufacturing process, as it helps to ensure that parts and structures meet required standards. In many industries, third-party NDT inspection is mandatory to guarantee impartial and objective evaluation of the parts and structures. However, some companies attempt to circumvent third-party inspection by setting up their own NDT laboratory and conducting the inspections in-house.
While this approach may seem more convenient and cost-effective, it raises serious concerns about the impartiality and objectivity of the inspection results. The integrity of the NDT process is dependent on the use of independent, third-party inspectors who are not affiliated with the company manufacturing the parts or structures. By doing so, companies can ensure that the parts and structures are evaluated objectively, without any conflicts of interest.
Companies should not take shortcuts when it comes to NDT inspection. While it may be tempting to conduct the inspection in-house, it is important to remember that impartial and objective evaluation is crucial for the success of the NDT process. Companies that invest in independent, third-party NDT inspection can be confident that their parts and structures meet required standards, ensuring the quality and safety of their products.
To prevent companies from evading third-party NDT inspection, the following steps can be taken:
1. Implement regulations and standards: Governments and industry organizations can establish regulations and standards that require third-party NDT inspection for all parts and structures. These regulations should be strictly enforced to ensure that companies comply with the requirements.
2. Promote the importance of impartial evaluation: Companies can be educated about the importance of impartial evaluation in the NDT process. This can help to raise awareness about the dangers of in-house NDT inspection and encourage companies to invest in independent, third-party inspection.
3. Enhance the accreditation process: The accreditation process for NDT inspection companies can be enhanced to ensure that only reputable and qualified organizations are authorized to conduct NDT inspections. This will help to reduce the number of companies that are not equipped to provide impartial and objective evaluation.
4. Encourage transparency: Companies that conduct NDT inspection should be encouraged to be transparent about their methods and results. This will help to promote confidence in the NDT process and increase the credibility of the results.
5. Foster collaboration: Governments, industry organizations, and NDT inspection companies can work together to promote the importance of impartial and objective evaluation in the NDT process. This can help to raise awareness about the dangers of in-house NDT inspection and encourage companies to invest in independent, third-party inspection.
There have been numerous cases of companies evading third-party NDT inspection and conducting the inspections in-house. However, specific cases are not publicly available as they are often confidential and not disclosed to the public. Nevertheless, the consequences of such actions can be severe, including fines, legal action, and damage to a company's reputation. In some industries, such as aviation and nuclear power, the consequences can be even more severe, including potential safety hazards and loss of life. It is important for companies to understand the importance of impartial and objective evaluation in the NDT process and to invest in independent, third-party NDT inspection to ensure the quality and safety of their products.

Has any member come across instances where companies have attempted to evade third-party NDT inspection and conduct the inspections in-house? If so, how frequent is this issue in the industry?

NDT-Inspect started the discussion API, methods for calculating remaining life of equipment in the forum Codes and Standards

3 years ago
API (American Petroleum Institute) is a trade organization that develops standards for the oil and gas industry. API has developed several methods for calculating the remaining life of equipment and structures in the oil and gas industry, including methods for calculating the remaining life due to corrosion.
One such method is the API RP 571: Damage Mechanisms Affecting Fixed Equipment in the Refining Industry. This guideline provides a framework for identifying, evaluating, and mitigating damage mechanisms, including corrosion, that can affect fixed equipment in the refining industry.
To calculate the remaining life of equipment due to corrosion using the API RP 571 method, the following steps should be followed:
1. Identify the type of corrosion that is occurring: This includes identifying the type of corrosion (such as uniform corrosion, pitting corrosion, or crevice corrosion) and the specific corrosion mechanism that is at play (such as galvanic corrosion or corrosion caused by stress).
2. Determine the corrosion rate: This involves measuring the thickness loss of the material over a specific period of time, typically in millimeters per year (mm/year). The corrosion rate can be determined through various methods, including corrosion coupons, electrochemical techniques, or corrosion probes.
3. Determine the remaining life: Once the corrosion rate has been determined, you can use it to calculate the remaining life of the equipment. This can be done by dividing the remaining thickness of the material by the corrosion rate. For example, if the remaining thickness of a material is 5 mm and the corrosion rate is 0.5 mm/year, the remaining life of the structure would be 10 years.
It is important to note that these calculations are estimates and the actual remaining life of the equipment may be longer or shorter depending on various factors. It is also important to regularly monitor the equipment to ensure that it is safe and in good condition.
