Complex investigations are sometimes best completed with evidence collected by field or on-site work to apply our perspective and observations to laboratory findings. Sometimes, field characterization is all that is required to yield data that decisions can be made from. Other times, samples are collected for analysis upon returning to the laboratory. A few techniques that are commonly used during on-site investigations are summarized below. A documented report accompanies site visits with the appropriate depth of documentation determined by the client and CTL.
- Ultrasonic Thickness Testing to obtain the wall thickness of metal and equipment in situ.
- Dye Penetrant Testing a surface technique for crack identification.
- Video Probe and Borescope Inspection for the evaluation of the interior of a pipe or vessel for corrosion and cracking
- Inspection and Sample Collection for corrosion assessment or metallurgical evaluation, including assessment for environmental corrodents.
- Soil Sampling for indexing for corrosivity by laboratory analysis.
- Stray Current evaluation for suspect sets up.
- On-Site Corrosion Testing for confidential material applications or difficult to transport media. This may include laboratory type tests or test racks for insertion into the process equipment.
- On-site environmental monitoring.
