SERVICES
Iris Inspection Services® is a tubing inspection specialty company. We provide a comprehensive inspection program consisting of multiple tube inspection techniques to determine the integrity of all types of heat exchangers, air coolers, boilers, chillers, as well as any other tubing.
Our specialization and extensive experience in heat exchanger inspection ensures that components are properly evaluated to detect damage or defects; thereby allowing reliable determinations about whether tube bundles should remain in operation, be repaired or replaced. Failures can result in unplanned shutdowns, dangerous catastrophic failures, or severe costly damage. Our staff of specialists can inspect your heat exchangers utilizing the following methods:
Eddy Current Testing (ECT)
Application: Eddy current testing is an electromagnetic testing technique usually used to inspect non-magnetic materials.
Remote Field Testing (RFT)
Application: Remote-field testing is an electromagnetic testing technique mainly used to find defects in ferromagnetic tubing.
Near Field Testing (NFT)
Application: Near-field testing is an electromagnetic technique mainly used to find internal defects in externally finned ferromagnetic tubing.
Magnetic Flux Leakage (MFL)
Application: Magnetic Flux Leakage is an electromagnetic testing technique mainly used to find defects in ferromagnetic tubing.
Internal Rotary Inspection System (IRIS)
Application: The internal rotary inspection system (IRIS) is an ultrasonic non-destructive testing (NDT) technique used to inspect ferromagnetic tubing and non-magnetic tubing.
Remote Visual (RVI)
Application: cost-effective inspection technique used to capture real-time views and images from inside voids such as tubes, pipes, rotating machinery, engines, heat exchangers, tray towers, refractory-lined vessels and enclosed structures.
Iris Inspection Services® also offers experienced Heat Exchanger T/A Coordinators along with IRIS T/A Tracker
Never again be in the dark about the status your equipment. Is it open? Is it cleaned? Is the inspection complete or at 50%? Just login to our secure IRIS T/A Tracker and check the status. When the inspection is complete, the report will be immediately available for download. Our experienced Heat Exchanger Coordinators will constantly track the location and status of each piece of equipment and upload the status to IRIS T/A Tracker as conditions change.
Final Reports
Iris Inspection Services® utilizes advanced reporting software. Using this software our specialist can very quickly generate a concise and easy to interpret report.
Once the inspection and data analysis are complete, an on-site final report is immediately generated. This report consists of a detailed description of the inspection findings, a summary of the test results, tube sheet maps; color coded by percentage loss/remaining and damage type, side views of the exchanger indicating percentage loss/remaining, detailed information on each tube inspected, along with screen captures of the typical indications found. In addition, supplemental tube sheet maps can be generated for tube plugging or selective re-tubing.
Upon completion of our final reporting, our tubing inspection specialists will generate an electronic report along with a spreadsheet of report details.
With Iris Inspection’s advanced on-site reporting there is no more waiting days for a report, decisions based on concise data can be made in less than an hour.
