Types of Inspections
Boiler Visual Inspections
We service natural gas, biomass, petroleum, chemical recovery, and heat recovery (HRSG) boilers. We direct ultrasonic thickness mapping to more effectively target problem areas of a boiler and to ultimately cut down on unneeded data points.
Dye Penetrant (PT)
A widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). PT is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
Eddy Current Testing
An electromagnetic testing method used in NDT to detect near surface anomalies in conductive material.
Hardness Testing is performed in the field with a small hand-held device and is used to gauge the strength of the metal. This is useful when determining the correct welding electrode to use during structural repair.
Magnetic Lift Off Testing
Measurement of lift-off can be used to assess the thermal insulation thickness and it has the potential to reduce the lift-off effect in pulsed eddy current testing.
Magnetic Particle Testing (MPT)
A non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part to facilitate flaw detection.
A NDT method, duplicating the microstructure of a component in order to observe grain structure at high magnification.
Phased Array UT (PAUT)
An advanced method of ultrasonic testing used to determine component quality and detect flaws in manufactured materials, such as welds. In addition, it can be effectively used for wall thickness measurements in conjunction with corrosion testing. This NDT technique is minimally invasive, highly flexible, and offers multiple applications.
Positive Material Identification (PMI)
The analysis of a metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. IIA has implemented X-ray fluorescence (XRF) which is a typical method for PMI.
Pulsed Eddy Current Testing
A non-destructive examination technique used for detecting flaws or corrosion in ferrous materials or measuring the thickness of objects. PEC is useful in situations where an object’s surface is rough or inaccessible. This method doesn’t require surface preparation or removing any insulation.
Ultrasonic Thickness Testing (UTT)
A volumetric non-destructive testing method that uses sound waves to propagate through an object.
Weld Procedure and Qualification (CWI)
Qualification to either American Welding Society (AWS) or American Society of Mechanical Engineers (ASME) standards through Certified Welding Inspectors (CWI) with mobile capabilities for your convenience.
Visual & Optical Testing
For DA tanks, steam turbines, fans, pressure vessels, high energy piping, stack/tower, etc. We have highly skilled employees that will inspect for indications such as cracks, corrosion, erosion, damage, and structural integrity.
