The terms Nondestructive Examination (NDE), Nondestructive Inspection (NDI), and Nondestructive Evaluation (NDE) are also commonly used to describe these techniques. Because NDT does not permanently alter the physical conditions of the piece being inspected, it is a highly valuable technique that can save both money and time in product assessment, troubleshooting, and research.
Some NDT methods include ultrasonic, electromagnetic, radiographic, remote visual inspection, guided waves, magnetic particle, penetrant testing, etc. All these methods have been subject to significant improvements during the last decade, therefore making available more accurate tools in the field of materials examinations.
Advantages of Advanced Ultrasonic (AUT) and other advanced NDT technologies:
- Higher POD, Resolution & Sensitivity.
- Accurate location, characterization, and sizing of defects.
- Reduced inspection times compared to conventional methods.
- Permanent Digital Records. Potential for reduced manpower.
- Greater penetration than conventional radiography (large thickness).
- Root, cap, and mid-wall coverage simultaneously in a one-line scan.
- Flexibility- easily adjustable to varying diameters, thicknesses, and weld configurations.
- Full A-scan raw data with imaging and post processing.
- Excellent replacement for conventional radiography with almost no radiation hazard!
Petrochemical Pressure Vessel NDT Services
We have provided worldwide proven inspection solutions designed to perform petrochemical pressure vessel weld inspections which comply with the most demanding construction codes such as ASME Code Case 2235-9, ASM B&PV Sec VIII, Div. 1 & 2, 2013 edition, as well as other construction welding inspections. We design inspection configurations to fit each application need – TOFD, Phased Array, Digital Radiography as well as other Electromagnetic Superficial Methods and Techniques.
The versatility of our technologies and equipment allow in-service inspection of pressure vessels containing hazardous materials. They conduct the inspections using NIST-traceable portable calibration equipment and qualified inspectors certified in accordance with American standards.
The meticulous qualification process of the inspection procedure prior to performing the inspection itself permits adjusting the system to the specific needs of the project, thus yielding reliable results even without the removal of the protective pain layers on the vessels.
We supply proven solutions designed to perform pressure pipelines weld inspections according to approved codes, which include:
- ASME B 31.X
- Code Case 181
- ASME P&PV Section V, Article 4
The technology used also complies with the requirements of other fabrication and installation codes, such as API 1104 for the transportation of petroleum and petroleum by-products, as well as other pipeline construction welding inspections.
We design in-service inspections of piping in accordance with B.31.1 and ASME B31.3 as well as API and other piping codes.
We offer the most efficient portable solutions for the following:
- Corrosion detection applications for in-service pipes and pipelines
- Inspection of above ground conventional and coated pipes
- Detection of corrosion at supports and pipe racks
- Inspection of through-wall pipe
- Detection of corrosion under insulation (CUI)
- Inspection of buried pipes
- Inspection of vertical pipes
- Application of guided waves technology to avoid unnecessary excavation, coating removal or scaffolding unless flaws are detected
- Inspection of high temperature insulated pipes
