Hydrophore (Booster Pump System) Inspection

Periodic inspections of pressure equipment—carried out by mechanical engineers with sufficient technical competence and expertise—help reduce and prevent work accidents and ensure occupational safety. For safe operation of pressure systems and their safety components within a workplace, these units must be periodically inspected for corrosion, leakage, wear, cracks, deformation, connection integrity, temperature, pressure, cleanliness, and functionality.

Hydrophore Periodic Inspection Interval

According to the relevant legislation, Annex III “Provisions on Maintenance, Repair, and Periodic Inspection” of the Regulation, Article 1.4 states:

“If the periodic inspection interval and criteria are not otherwise defined in the standards, the periodic inspections of work equipment shall be carried out within the intervals and criteria recommended by the manufacturer.
If these are not defined by the manufacturer, inspection intervals must be determined considering factors such as environmental conditions, frequency of use, and duration of use, based on a risk analysis and evaluation.
In any case, the inspection interval shall not exceed one year unless specified otherwise in the Regulation.”

Therefore, depending on usage frequency, hydrophore systems must undergo periodic inspection at least once a year, and more frequently if necessary. This is a legal requirement.

Hydrophore Periodic Inspection Regulation

Periodic inspections of hydrophore systems are conducted in accordance with the “Regulation on Health and Safety Requirements for the Use of Work Equipment,” issued under the Labor Law.

Annex III, Section 2.1 “Pressure Vessels and Installations,” Article 2.1.1 states:

“As a fundamental principle, a hydrostatic test must be performed on pressure vessels. Unless stated otherwise in the standards, these tests must be performed at 1.5 times the operating pressure and at intervals not exceeding one year.
However, if hydrostatic testing is not possible due to the nature of the equipment or operational conditions, non-destructive testing (NDT) methods defined in the standards may be used instead.
In such cases, the periodic inspection report must clearly indicate this situation with justification.”

As hydrophores are classified as pressure vessels, they are inspected according to these principles and the relevant standards.
