Steel City NDT

NDT/NDE SERVICES

As your premier leader in non-destructive testing in Pittsburgh, Steel City NDT offers a wide selection of NDT solutions. Non-destructive testing also called non-destructive examination or NDE is an effective way to inspect your equipment since it does not require us to enter the asset or shut down the asset, allowing for an increase in your operation's productivity and uptime.


Find out how non-destructive testing (NDT) and non-destructive examination (NDE) in Pittsburgh can reduce costs and drive your business forward.


What Is NDT Used For?

Non-destructive testing has a wide range of applications in engineering and manufacturing. It can be used to determine the structural integrity of a building or structure, such as a bridge, or it can be used to detect any defects in your mechanical equipment or the products you produce. It is used across all industries and can also determine the integrity of a residential structure. 


Non-Destructive Testing Techniques

Our NDT techniques are designed to detect or quantify certain damages. We offer an extensive range of NDT techniques, including:

  • Magnetic Particle Inspection (MPI)
  • Penetrant Testing (PT)
  • Ultrasonic Testing (UT)
  • Visual Inspection (VT)
  • Certified Welding Inspector (CWI)


Magnetic Particle Inspection (MPI)
MPI is a quick, cost-effective NDT inspection method used to detect surface and subsurface anomalies in ferromagnetic materials such as iron, nickel, and cobalt. For MPI, Steel City NDT technicians magnetize a ferromagnetic material and apply it to the test object. Flaws are then detected when the magnetic field is interrupted as it flows through the test object and there is a flux leakage.

Ferrous iron particles coated with a dye pigment are then applied to the object. These particles will indicate a discontinuity in the material by forming a cluster over it. This can be detected visually under proper lighting conditions. Steel City NDT utilizes Dry Magnetic Particle – Iron Oxide, Wet Fluorescent Magnetic Particle (oil or water-based) – Iron Oxide, Wet Fluorescent Magnetic Particle Inspection and Test (Crack), and Wet Fluorescent Magnetic Particle Test (Crack) to detect surface/near-surface defects in ferromagnetic material.


Penetrant Testing (PT)
PT is used by Steel City NDT to find surface-breaking discontinuities in non-porous, smooth surfaces and is commonly used to detect casting, welding, and forging defects such as leaks and cracks. This testing works based on capillary action, where liquid rises when confined to a smaller opening. Once our technician removes the excess penetrant and applies the developer, our trained inspector will identify any remaining penetrant to indicate a flaw. At Steel City NDT, we offer Dye Penetrant Inspection (DPI) and Fluorescent Penetrant Inspection.


Ultrasonic Testing (UT)
UT is a technique utilized by Steel City NDT to measure the propagation of mechanical vibrations or ultrasonic waves through the material to examine its properties, determine elasticity, measure thickness, and detect discontinuities such as cracks, corrosion, flaws, ad more.

Our experienced technicians use ultrasonic testing to detect defects on the surface and subsurface while providing you with accurate readings when it comes to the discontinuity shape and size. Steel City NDT utilizes Ultrasonic Thickness Testing (UTT), Shear Wave Ultrasonic Testing (SWUT), B-Scan, C-Scan, S-Scan, Pulse-Echo, and through-transmission testing methods.


Visual Inspection (VT)
VT is one of the most basic and reliable forms of NDT and can come in various specifications or codes. Steel City NDT technicians perform this testing using sight to determine any visual anomalies of the object. Steel City NDT utilizes American Petroleum Institute (API), American National Standard Institute (ANSI), and Certified Weld Inspector (CWI) for visual inspection.

Certified Welding Inspector (CWI)
CWI is a type of visual inspection where the weld is observed with the naked eye or by using a magnification device to detect any anomalies in the weld. Our technicians can determine if the weld meets all the requirements of the welding procedure specification (WPS). With CWI, our technicians can also detect any problems with the weld early on so it can be repaired before it can become a more expensive or difficult issue to repair. Our highly trained technicians check for defects such as incomplete fusion, slag inclusion, and spatter.

In addition to detecting defects in welds, we can also qualify welders and weld procedures to meet your needs.


Benefits of NDT and NDE

There are many benefits to non-destructive testing and examination. This type of testing offers:

  • Minimal downtime because there is no need to reassemble equipment 
  • Cost-efficiency 
  • Reduced waste as it does not damage sample products
  • Reduced risk of equipment failure and repair costs 
  • Reduced risk of accident due to faulty equipment or structure
  • The most comprehensive testing possible
