The Matthews Training course ‘Inspection and maintenance of pressure relief valves (PRVs) is a practical training course tailored to the specific needs of the owners/operators of pressure systems. It combines classroom instruction and practical workshop training on various types of PRVs. It is an independent course that covers various types of PRV designs and is not specific to any equipment manufacturer. The global objectives of the course programme are to:
• Provide a mechanism for training and familiarisation of delegates staff with pressure relief valves, which are important safety-critical items of pressure equipment under The PSSRs and similar statutory requirements in other countries
• Enable delegates to develop familiarity with the practical aspects of PRV inspection and maintenance and demonstrate this familiarity to external bodies such as the site Competent Person and HSE.
This course operates as a public course at various venues and on demand as an in-house course at client’s sites. For in-house courses, arrangements can be made, if required for the issue of ASME certificates under our ASME Global Training Provider agreement.

2.1 Presentation
The course is designed for a maximum of 8 delegates per course. These will be split into groups to make the best use of the PRV samples and available space for the stripdown/assembly/testing exercises.
The course duration is 4 days. This will consist of a combination of classroom and workshop instruction involving practical exercises
Classroom presentations use computer based (Powerpoint) material supported by photographs and practical samples.
For the practical instruction, the following equipment is used:
• Cut-away models of various PRV types for demonstration purposes
• Sample PRVs for corrosion/damage/NDT/ stripdown assessment
• Sample PRVs for lift and seat leakage testing
• Hydraulic test rig
• Measuring equipment, accessories, NDT materials, consumables and small tools as required
2.2 Course content
Topics covered in the course include:
• Principles of pressure relief
• PRV design fundamentals/components and operation
• PRV sizing and terminology
• Review of the content of codes/ standards and their influence on PRV inspection:
• Pre-pop testing
• Setting of lift pressure
• Seat leakage (bubble) testing
• Corrosion assessment/casing wall thinning and NDT
• NDT/leak test of back-pressure bellows
• Seat lapping and surface finish assessment
• Re-assembly alignment
• Inspection reporting
• Demonstrating the effect of incorrect adjustment
• PRV certification and administration requirements (PSSR influences)
• Deciding PRV inspection periodicity
• Applying an RBI scheme to PRV inspection periodicity
2.2 Delegate Assessment
The course assessment will consist of three parts:
• Continuous assessment of delegates throughout the duration of the course, particularly during the participation exercises.
• Written tests comprising a combination of multiple choice and descriptive questions. The pass mark is 70%.
• Practical workshop assessment test on PRVs using a case study format
This course is operated by Matthews Engineering Training Ltd. Fees for the course are £1695+VATper delegate to include all course materials, books and exam/certification. To reserve a place contact Cliff Matthews directly on enquiries@matthews-training.co.uk
