Periodic Inspection and Testing of Hot Water and Steam Boilers

As part of industrial safety practices and preventive maintenance programs, I performed periodic inspections, functional tests, and safety evaluations of hot water boilers and steam boilers, in accordance with relevant standards and legal requirements.

Applicable Standards and Guidelines:

• TS EN 12953 – Shell boilers

• TS EN 12828 – Heating systems in buildings – Design for water-based heating systems

• TS EN 13445 – Unfired pressure vessels

• Regulation on Health and Safety Requirements for the Use of Work Equipment (Turkey)

Scope of Work:

✅ Visual Inspections:

• Checking for corrosion, leakage, cracks, and mechanical deformation on boiler body, piping, and connections.

• Inspection of combustion chambers, flue gas systems, and refractory linings.

✅ Hydrostatic Pressure Testing:

• Applied on steam and hot water boilers to assess the pressure-retaining capacity of the system.

• Test pressures were typically set to 1.3–1.5 times the design pressure in line with regulations.

✅ Control and Safety Component Testing:

• Safety valve functional checks (set pressure calibration, leakage testing).

• Inspection and testing of pressure switches, level control systems, expansion vessels, and circulation pumps.

• Burner operation and flame control testing for liquid and gas-fired systems.

✅ Instrumentation & Calibration Checks:

• Verification of pressure gauges, thermometers, and temperature/pressure sensors.

✅ Documentation:

• Preparation of detailed inspection and test reports.

• Recording of non-conformities, follow-up actions, and re-inspection plans.

Types of Boilers Inspected:

• Steam boilers (high and low pressure)

• Liquid-fuel-fired and gas-fired hot water boilers

• Condensing boilers and industrial heating units

• Hot water systems with integrated expansion tanks and safety valves

All inspections were conducted by certified personnel using calibrated equipment, and documented in compliance with statutory requirements and quality standards.
