Amerapex offers a comprehensive program to detect Corrosion Under Insulation (CUI) using a variety of NDT technologies and detailed API visual inspections. Damage as a result of CUI can be costly and can lead to unwanted downtime. Put your trust in CUI experts. Put your trust in Amerapex.
Corrosion Under Insulation is a major area of concern for the petroleum and chemical process industries. CUI can result in sudden and hazardous leaks which can endanger plant personnel and surrounding communities.
Amerapex is an industry leader in turnkey Corrosion Under Insulation programs. We use a comprehensive evaluation of your specific CUI needs coupled with a wide array of NDT technologies and a detailed API 570 visual inspection. We are able to locate CUI cost effectively while maintaining a very high coverage rate. Amerapex developed programs that yield more accurate results while keeping craft support costs down to a minimum.
CUI PROGRAM METHODOLOGY:
- DATA COLLECTION & VALIDATION
Identify all CUI susceptible areas, collect P&ID/inspection isometrics.
4. REAL TIME RADIOGRAPHY
Used to inspect high-moisture and problem areas to determine if insulation removal is necessary.
2. VISUAL & TEMPERATURE SURVEY
This survey is used to identify the correct scope of the CUI inspection and identify the problem areas.
5. GUIDED WAVE ULTRASONICS
This additional screening tool is primarily used when space limitations restrict access by other NDT methods.
3. MOISTURE DETECTION
Using Neutron Backscatter, this survey identifies high moisture areas on piping and equipment.
6. PULSED EDDY CURRENT (PEC)
Pulsed Eddy Current (PEC) is an electromagnetic screen tool used to find degradation and defects in ferromagnetic materials caused by CUI. it provides a relative wall thickness measurement through non-metallic pipe protection.
