Magnetic Particle Testing (MPI / MT) in Ras Tanura
Magnetic particle testing reveals surface and slightly subsurface cracks in ferromagnetic steel by magnetising the part and applying fine iron particles that gather where the field leaks. It is the usual first choice for crane hooks, shackles, pins, lifting lugs and carbon-steel welds, and it gives a clear result at the part once the surface is prepared. Site of one of the world's largest oil refineries and export terminals, with continuous maintenance and turnaround activity.
Magnetic Particle Testing (MPI) in Ras Tanura: local context
Turnaround lifts at Ras Tanura often involve heavy plant items moved in tight laydown areas beside operating units, so proof load testing and NDT of lifting equipment are best completed well before the work window opens. Humid, salt-laden coastal air tends to speed up corrosion on hooks, shackles and boom welds, so EES pairs load testing with NDT of critical load-bearing parts and documents every result.
What we deliver in Ras Tanura
- ✓Detection of surface and slightly subsurface cracks, laps and seams in ferromagnetic carbon and low-alloy steel
- ✓Hooks (throat and shank), shackles, eye bolts, pins, swivels and lifting lugs on cranes and rigging
- ✓Welds and heat-affected zones on crane booms, jibs, spreader and lifting beams, pad-eyes and structural steelwork
- ✓Technique chosen to suit the item: electromagnetic yoke with visible particles on white contrast paint, fluorescent particles under UV-A light in a darkened area, or dry powder on rough or hot surfaces
- ✓Field applied in at least two directions at roughly right angles so cracks of any orientation are shown, with yoke lifting power and light levels checked at the start of each job
- ✓Surface preparation, demagnetisation where required, and re-test after cracks are ground out or repaired
- ✓A clear statement of limits: MPI cannot test non-magnetic materials such as austenitic stainless steel, aluminium or copper alloys (use DPI) and does not find deep internal flaws (use UT)
Standards
- ✓ASME BPVC Section V (magnetic particle examination)
- ✓ISO 9934 (magnetic particle testing) and ISO 17638 (magnetic particle testing of welds)
- ✓ASTM E709 (guide for magnetic particle testing)
- ✓ASME B30.10 (hooks) and client procedures for the items examined
Documentation
- ✓MT report stating technique, magnetising method, particles and lighting readings
- ✓Indication record with location, length and orientation, with photographs
- ✓Accept or reject result against the specified criteria
- ✓Re-test record after grinding or weld repair

FAQs
Do you provide Magnetic Particle Testing (MPI) in Ras Tanura?＋
Yes. EES provides Magnetic Particle Testing (MPI) at client sites in Ras Tanura, including Ras Tanura Refinery and Ras Tanura Terminal. Contact us with your requirement and we will confirm scope and scheduling.
Which standards and documents apply to Magnetic Particle Testing (MPI) in Ras Tanura?＋
Work in Ras Tanura is aligned with the following standards and references: ASME BPVC Section V (magnetic particle examination); ISO 9934 (magnetic particle testing) and ISO 17638 (magnetic particle testing of welds); ASTM E709 (guide for magnetic particle testing); ASME B30.10 (hooks) and client procedures for the items examined. On completion you receive: MT report stating technique, magnetising method, particles and lighting readings; Indication record with location, length and orientation, with photographs; Accept or reject result against the specified criteria.
Can magnetic particle testing be used on stainless steel or aluminium?＋
Not on austenitic stainless steel (such as 304 and 316), aluminium or copper alloys, because they cannot be magnetised in the way the method needs. For those materials we use dye penetrant testing, which finds surface-breaking defects on any non-porous surface.
Does paint or coating have to be removed before MPI?＋
A thin, well-bonded coating can sometimes be tolerated when the procedure allows it and the field is verified, but heavy paint, scale, rust, oil and grease must be removed. We agree the surface preparation with you before the day so the test is not delayed on site.
