What is Air Tank Periodic Control?

Air tank periodic control is a mandatory technical inspection carried out at regular intervals to determine whether compressed air tanks  are safe, leak-free and operating in accordance with the legislation. Air tanks are  classified as pressure vessels and involve a serious risk of explosion.

Legal Basis (Turkey)

1.              Regulation on Health and Safety Conditions in the Use of Work Equipment

2.              Annex-III / Pressure Vessels

3.              Control period: 1 time in 1 year at the latest

Depending on corrosion, heavy use, or manufacturer demand, this period may be shorter.

How is Air Tank Periodic Control Done?

1️⃣ Document Control

1.              Manufacturing information (CE, serial no, year of manufacture)

2.              Maximum working pressure (PS)

3.              Previous periodic control reports

4.              Tank hacmi (lt)

2️⃣ Visual Inspection

1.              Body and weld seams

2.              Corrosion, crack, deformation

3.              Legs, chassis and connections

4.              Labels and warning signs

3️⃣ Safety Equipment Check

1.              Safety valve

1.              Does it work?

2.              Is the setting pressure appropriate?

2.              Pressure gauge

1.              Is it legit?

2.              Is the calibration valid?

3.              Relief valve

1.              Is condensate drainage smooth?

4️⃣ Tightness Check

1.              Flanges

2.              Resource regions

3.              Valve connections

4.              Soap scum or pressure drop method

5️⃣ Pressure Test (Hydrostatic Test)

It is the most critical stage.

1.              The tank is filled with water

2.              1.5 times the maximum working pressure is applied

3.              Wait for a certain period of time

4.              Deformation, leakage or damage are observed

⚠️ During hydrostatic testing, no air is used, only water.

6️⃣ Reporting

1.              Determination of conformity / non-conformity

2.              Risk assessment

3.              Decision not to be used  if necessary

4.              The authorized person performing the control:

1.              Title

2.              Signature

3.              History

Who Can Do the Check?

1.              Mechanical Engineer

2.              Mechatronics engineer

3.              Metallurgical and materials engineer

4.              Authorized Type A inspection bodies

The employer or maintenance personnel cannot perform periodic checks.

What happens if the control is not done?

1.              Administrative fine

2.              Risk of explosion

3.              Criminal liability in case of work accident 

4.              Insurance invalidity

5.              Work stoppage

What Should Be on the Air Receiver Control Label

1.              Check date

2.              Next check date

3.              Person/organization performing the control

4.              Report number
