What Is It?

A compressor air tank is an essential component used to store and regulate the air pressure generated by compressors. These tanks maintain stable air pressure and ensure the efficient operation of the system. Regular periodic inspections of compressor air tanks are essential for guaranteeing safety, efficiency, and longevity. The pressure and mechanical stress on the inner and outer parts of air tanks are controlled through regular inspections.

What Are the Standards?

Periodic inspection of compressor air tanks is carried out according to specific standards and regulations designed to ensure their safe and efficient operation:

• ASME Boiler and Pressure Vessel Code (BPVC) Section VIII: Defines the design, manufacturing, and testing processes for compressor air tanks.

• PED (Pressure Equipment Directive) 2014/68/EU: European Union standards for the safety and design of pressure equipment.

• TS 12232: The Turkish safety regulation applicable to pressure vessels, including compressor air tanks.

• TS EN 13445: European standard defining the safe design and manufacturing requirements for pressure vessels.

How Is It Done?

The periodic inspection of compressor air tanks involves a series of tests and evaluations performed by qualified engineers. The process typically includes the following steps:

• Visual Inspection: Checks for cracks, corrosion, deformation, or leaks on the tank’s external surface. Rust or other signs of wear are also examined, especially on metal surfaces.

• Pressure Test: The tank is pressurized to a specified level to test for leaks and structural strength, verifying its ability to safely handle internal pressure.

• Weld and Joint Inspection: All welds and joint connections are examined in detail to detect potential weaknesses or fractures that may compromise tank safety.

• Corrosion Test: Inspects both the inner and outer surfaces for signs of corrosion. Since air entering the tank may contain moisture, internal corrosion is a significant concern.

• Safety Equipment Check: Safety valves, pressure gauges, and other protective components are tested to ensure the system is safeguarded against overpressure.

• Functional Tests: The tank is tested in conjunction with its connected compressor system to ensure it operates properly and efficiently.

Why Is It Applied?

Periodic inspection of compressor air tanks is crucial for several reasons:

• Safety: Since compressor air tanks operate under high pressure, any malfunction could lead to serious safety risks. Inspections help detect potential hazards in advance.

• Legal Compliance: Many countries require compressor air tanks to be inspected at regular intervals. Compliance with legal regulations helps businesses meet their obligations.

• Efficiency: Regular maintenance and inspection ensure that the tank operates efficiently and that potential problems are identified early.

• System Continuity: The compressor air tank is a critical component of many industrial systems. Periodic inspections ensure uninterrupted operations.

Where Is It Applied?

Compressor air tanks are widely used across many industrial sectors. Main application areas include:

• Construction and Mining: Used to improve the operational efficiency of air-powered tools and equipment.

• Manufacturing Industry: Found in production lines, automation systems, and air-operated machinery.

• Chemical and Petrochemical Industry: Used in chemical processes and gas compression operations.

• Food and Beverage Industry: Utilized in food production facilities, packaging systems, and various processing stages.

• Energy and Power Generation: Required in power plants and energy facilities to ensure efficient system operation.

Equipment and Techniques

The primary equipment and testing techniques used during the periodic inspection of compressor air tanks include:

• Pressure Testing Devices: Used to test the tank’s durability and leakage resistance under pressure.

• Ultrasonic Thickness Gauge: Measures material thickness and detects corrosion or wear on metal surfaces.

• Endoscopic Cameras: Used for internal visual inspections, allowing detailed examination of the inner surfaces.

• X-ray and Ultrasonic Testing (NDT): Non-destructive testing methods used to detect cracks or weaknesses in welds and joints.

• Safety Equipment Testing Devices: Used to check the proper functioning of safety valves and pressure indicators.

Advantages

The periodic inspection of compressor air tanks provides several benefits:

• Safety: Detects potential faults early, preventing major accidents.

• Increased Efficiency: Ensures the tanks operate effectively and maintain system performance.

• Legal Compliance: Helps avoid legal penalties by ensuring compliance with safety regulations.

• Longer Lifespan: Extends tank life and reduces maintenance costs.

• Environmentally Friendly: Minimizes environmental impact by preventing leaks and system failures.

Disadvantages

Some disadvantages of periodic inspection for compressor air tanks include:

• Cost: Inspections and testing may result in additional expenses.

• Time-Consuming: Detailed testing and inspection procedures may take time and affect operational schedules.

• Expertise Requirement: Requires skilled professionals and specialized equipment, adding to resource needs.
