PD CEN/TS 13445-501:2018

What is PD CEN/TS 13445-501 - Unfired pressure vessels about?  

PD CEN/TS 13445 is a series on unfired pressure vessels. Unfired pressure vessels are very helpful in preventing corrosion by being an instrument of heat exchange as they are not exposed to combustion or burner fire. PD CEN/TS 13445-501 is intended for the application of AT on metallic pressure equipment during controlled loading. The overall aims of PD CEN/TS 13445-501 are: 

• To detect, locate and grade areas with evolving imperfections 
• To provide the manufacturer with the possibility to compare results of the first test with those of subsequent periodic inspections 
• To determine the possibilities and limits of ae testing (at) for pressure equipment 
• To establish a common basis for procedures to perform at, taking into account the specific characteristics of the equipment under test 
• To define the criteria, features and grades essential for the evaluation of test results 
• To suggest follow-ups to the test 

Who is PD CEN/TS 13445-501 - Unfired pressure vessels for? 

PD CEN/TS 13445501 on unfired pressure vessels is useful for: 

• Pressure vessel manufacturers 
• Design engineers 
• Quality control personnel 
• Research and development facilities 

Why should you use PD CEN/TS 13445-501 - Unfired pressure vessels?  

An unfired pressure vessel is any type of pressure vessel that is not fired. Since it is an unfired vessel, there is a lesser risk of overheating. With these vessels, the occurrence of corrosion due to extremely high temperatures and other related factors can be prevented. PD CEN/TS 13445-501 discusses the acoustic emission for pressure vessels.  

The main target of the acoustic emission testing of pressure equipment is to detect acoustic emission sources caused by phenomena generated by the applied load to the equipment local plastic deformation, crack initiation, subcritical crack growth, surface rubbing in existing cracks, corrosion, leakage, etc. 

In PD CEN/TS 13445-501 testing of the acoustic emission for pressure vessels is carried out by preliminary information, written test instruction requirements, pre-test measurements and various types of test steps. Using PD CEN/TS 13445-501 you can apply acoustic emission testing on metallic pressure equipment during controlled loading.
