Our Inspection Method

Step-by-Step Air Receiver Inspection You Can Trust

Preparation

Written Scheme of Examination (WSE): A competent person must create or review a Written Scheme of Examination (WSE), which specifies:

•Which parts of the system (e.g., pressure vessel, protective devices, pipework) must be examined.

•The nature and frequency of inspections.

•System Review:

Gather all relevant documentation, including:

•Design specifications and operating limits.

•Maintenance and inspection records.

Pre-inspection Planning:

Prepare the system for inspection, including draining, venting, and isolation as required.

Visual Inspection

A thorough visual examination is conducted to identify:

•Corrosion or Erosion: Check for rust, pitting, or thinning of the pressure vessel wall.

•Leaks: Inspect for signs of leaks, particularly around joints, valves, and seals.

•Cracks or Deformations: Look for bulges, cracks, or weld defects that may compromise the structural integrity.

•External Damage: Assess for dents, abrasions, or other mechanical damage.

Internal Inspection

• Accessing the Vessel Interior: If safe, inspect the inside of the vessel after it has been depressurized and cleaned.

•Internal Corrosion and Deposits: Check for scale, sludge, or any buildup that could affect performance or safety.

•Examine Welds and Seams: Inspect welds for cracks, porosity, or other defects.

•Check Internal Components: Inspect baffles, supports, and other internal features for wear or damage

Non-Destructive Testing (NDT)

If required, the inspector may perform NDT techniques to evaluate the condition of the vessel without damaging it

•Ultrasonic Testing (UT): Measures wall thickness and detects hidden flaws.

•Radiographic Testing (X-rays): Identifies internal defects like cracks or voids.

•Magnetic Particle Inspection (MPI): Used for detecting surface and near-surface cracks.

•Dye Penetrant Testing (DPT): Highlights surface cracks or leaks.

Pressure Testing

• Hydrostatic Testing: The vessel is filled with water and pressurized to a specified level to check for leaks or weaknesses.

•Pneumatic Testing: Compressed air or gas is used as a test medium (less common and higher risk than hydrostatic testing).

These tests are usually performed when specified in the WSE or after repairs.

Inspection of Safety Devices

• Relief Valves: Check that safety relief valves operate at the correct pressure and reseal properly.

•Pressure Gauges: Verify accuracy and proper functioning.

•Other Protective Devices: Inspect automatic shutoff controls, alarms, or other safety features.

Reporting and Documentation

• Inspection Report: A detailed report must be prepared, including:

•Findings of the inspection.

•Any defects or concerns identified.

•Recommendations for repairs, maintenance, or further testing.

•Compliance Certification: If the system passes inspection, it is certified for continued use.

•Recordkeeping: All inspection reports and certificates must be kept for the lifespan of the pressure system.

Repairs and Follow-up

• If defects are identified, repairs must be carried out by competent personnel following appropriate standards.

•Reinspection or additional testing may be required after repairs to confirm compliance.

Frequency of Inspections

• The frequency of inspections is determined by the WSE, based on the type, operating conditions, and risk associated with the pressure system.

•Inspections are typically conducted every 1–5 years, depending on the system.

Legal Compliance

•Compliance with PSSR 2000 is a legal requirement in the UK.

•Employers and operators are responsible for ensuring that all pressure systems are inspected and maintained as per the WSE.

This thorough inspection process ensures the system operates safely and efficiently, minimizes risks, and complies with regulatory requirements.
