What is the first step when cleaning a duplex strainer?

The initial step in cleaning a duplex strainer is to bleed pressure prior to opening the compartment cover. This step is crucial because it ensures safety for the person performing the maintenance. When duplex strainers are in operation, they are subjected to the pressure of the system, and opening the strainer without relieving that pressure could lead to an uncontrolled release of fluid, which poses a risk of injury or damage.

By bleeding the pressure first, you create a safe working environment. It allows for the safe removal of the cover and prevents any sudden discharge of fluid, which could also lead to contamination or spillage in the area. Once the pressure has been relieved, the maintenance technician can proceed with other steps, such as removing the strainer cover or flushing with clean oil, without the risk associated with a pressurized system.

This order of operations is critical in any maintenance task involving pressurized equipment, reinforcing the importance of safety procedures in the marine and industrial settings.
