Everything you need to know about corrective maintenance

Corrective maintenance is usually associated with machines and equipment in factories. It can also be applied to items such as parts, devices, accessories, and other possibilities.

Thus, the main objective of corrective maintenance is to restore the asset. To the condition in which it can function as intended, either by replacing components or repairing systems. 

What is corrective maintenance?

Corrective maintenance is a process aimed at correcting problems as failures arise, as the name implies.

When a machine, equipment, part, or device has a drop in performance, breakdown or other malfunction. This type of maintenance is performed for the item to function properly again.

That is, the correction is made when the solution needs to be more immediate. Generally; it is not expected, which could cause financial losses to the company.

The main types of corrective maintenance are:

  • Emergency or unplanned maintenance

This type of maintenance is urgent as it can involve decisive and priority factors. Such as the physical safety of people, and the integrity of the environment. Interruptions that may affect the production or conservation of products.

When equipment stops working, it causes disorganization in the workflow. Most of the time, a high cost, as well as a potentially dangerous situation for the team.

Therefore, when it occurs, it is a warning sign to review the maintenance plan. 

  • Planned corrective maintenance

When professionals notice a drop in the performance of a machine or small faults. That affect its operation, it is important to carry out planned corrective maintenance.

In this case, it follows the maintenance plan, making it possible to schedule inspections. Schedule strategic stops and increase the safety of those involved, avoiding surprises.

Thus, the main difference between the two types is that planned corrective maintenance happens when there is a failure, but the equipment continues to function (potential failure), while unplanned maintenance occurs when the operation stops completely (after functional failure). .

How to apply the PF Curve in corrective maintenance?

The PF Curve is considered a fundamental analytical tool for good maintenance planning and control (PCM), guiding the manager in decision-making during the development of operational strategies.

The graph used in this curve aims to determine the interval between points P (potential failure = first failure or failure in an initial stage) and F (functional failure, responsible for the asset’s inability to function).

In this way, the PF Curve proves the performance and/or condition of the asset, making it essential to analyze the time interval between one failure and another to manage maintenance costs and asset availability.

According to the graph, the longer it takes to make the decision to correct the failure, the higher the repair cost.

This concept can be applied to any asset for which intervals are to be identified and, based on this, it is possible to create an efficient strategy for existing types of maintenance.
