Stream ES personnel hold internationally recognised PCN Level 2 qualifications in Ultrasonic (UT), Magnetic Particle (MP) and Dye Penetrant (DP) testing and have extensive experience in the application of these techniques for the inspection of steam boilers (firetube and watertube), pressure vessels, structural components and other critical manufacturing plant. We are qualified to inspect welds in plate and pipe including nozzles and nodes where this is required.
We also provide a range of other non-
Statutory examinations can be carried out according to insurance company, SAFed,
ASME/ASTM or Customer's internal guidelines, and non-
to ascertain the condition of plant or equipment which operates in an aggressive environment or under arduous conditions and which therefore is known to suffer deterioration during use. In this case the results are used to evaluate the wisdom of continuing to use the equipment in its present condition from a safety and/or operational (reliability) viewpoint, or to predict its future life for replacement and budgetting purposes.
to monitor the condition of critical plant which would present safety and/or environmental hazards if it were to fail, for example; pressure vessels, steam raising plant, refrigeration plant. Many of the requirements for this type of examination will be laid down in Government legislation or insurance company conditions, but others will be based on operating experience gathered over a period of time.
The crack is visible in the third thread from the bottom of the photo.
Regular UT inspection of high pressure ammonia vessels is required for the detection of incipient Ammonia Stress Corrosion Cracking (ASCC).
Early detection of such cracking allows remedial work or replacement to be planned into a routine shutdown period rather than a failure causing an expensive emergency shutdown.
