“…In the former case, a defect or failure causes high losses of product, energy, capital and can even cause human and environmental damages. Consequently, the inspection on pipelines over regular periods of time is critical (Sorabh, Raghav and Sengar, 2017). The proposal modification presented in Section 3 may be an alternative to model the inspection interval to this specific context.…”

Delay-time concept has been used in a large number of applications for modelling important aspects of reality, such as the dynamics of failures, which in practice occurs in two stages for the most devices. Concisely, a defect arises in a component or system followed by a subsequent failure after an interval called delay time. The effort to repair a defect is related to the time from when it can be firstly observed until its discovery by an inspection. However, a small number of contributions deal with the cost related to the time in which the system undergoes in the defective state. In addition, a repair action on a system that undergoes in defective state for a short period of time can have different consequences than the same action after a long period of time. Two examples are: a pipeline leakage defect and the repair of a defect in a tooth. In both cases, the consequences vary depending on the time in defective state. Hence, this paper proposes a way to take the defect cost into consideration according to the time in which the system undergoes in this state.

Striped defects are a common type of defects in oil pipelines, divided into horizontal and longitudinal stripes, and it is difficult to accurately quantify the results of conventional pipeline leakage magnetic detection to correspond to the type of defects and their extent. In this paper, a new type of oil pipe non-destructive testing equipment is proposed and designed based on the principle of magnetic leakage detection using three-dimensional finite element simulation, and the magnetic field distribution inside the equipment is simulated using ANSYS finite element analysis software to provide original data reference for the development of the new equipment.
