"On behalf of Battlefield Newfoundland I have to forward a huge thank you for your technician's services this year. He has gone beyond the call of duty to help us get through the last couple of months of processing equipment. If more of our vendors were like this it would make our job so much easier."
Robert Simms, Service Administrator
Battlefield Equipment, Mount Pearl Newfoundland

TUBULAR INSPECTION
OUR SERVICES
Domson can provide eddy current, remote field, and IRIS tubular inspection services for all markets including power generation, chemical, pulp & paper, oil & gas, and commercial applications. We offer highly competitive rates, CGSB certified technicians, and experienced staff.
OUR APPROACH
Tubular inspection requires extremely well-trained, experienced technicians and great attention to detail. Eddy current (ET) and remote field testing (RFT) are extremely valuable on their own, but are subject to many factors which can skew the results, making shallow defects appear deeper than they really are, or vice versa. Some of these factors may mask defects altogether or produce false indications. Our approach is to provide our clients with the most reliable data possible, and we can do this by providing data verification using secondary methods when questions arise. We use state of the art Olympus equipment that allows us to provide ET, RFT, IRIS, near field (NFT) and magnetic flux leakage (MFL) technologies all out of the same box. This means that if you need multiple methods performed during the same shift, you only pay once for the equipment charge, and we're available right there onsite to switch over. The secondary method may be as simple as performing IRIS on a sample of the tubes, or extracting a suspect tube for hands-on investigation. When the data or past service history justifies further investigation, it's nice to have peace of mind that all those squiggly little lines actually mean something!
EDDY CURRENT (ET) is used on non-ferrous tubing such as stainless steel, brass, copper-nickel, titanium, monel and others. It can locate and identify a wide variety of defects including corrosion, erosion, wear, pitting, baffle fretting and cracking. Eddy current can be performed using high "pull speeds", meaning a large number of tubes can be inspected in one shift.
REMOTE FIELD TESTING (RFT) is used on ferrous tubing such as carbon steel or ferritic stainless steel. It is used to detect volumetric metal loss such as erosion and corrosion. There are many variables which can affect RFT data, so verification of results on a small sample of tubes using a secondary inspection method is usually required.
INTERNAL ROTARY INSPECTION SYSTEM (IRIS) is an ultrasonic method using a rotating beam to scan the tube wall from the inside out. IRIS can produce easy-to-read thickness maps of the remaining wall thickness as if the tube were cut lengthwise and split open. This technology requires that the tubes be cleaned to near-new condition to ensure a good signal.
