Equipment and Technologies Used in PECT

Let’s dive into the heartbeat of PECT – the probes. These magical little devices are the eyes and ears of your inspection, sending out pulses of electromagnetic energy that bounce off the material being tested.

The three main types of PECT probes are absolute, differential, and array.

• Absolute probes are like solitary adventurers, measuring the absolute value of the electromagnetic field at a specific point. They’re great for getting a general idea of what’s going on, but they can’t tell you much about the location or depth of any defects.
• Differential probes are like detectives, comparing the electromagnetic field at two different points. This lets them pinpoint the location of defects more accurately, but they’re not as good at measuring their depth.
• Array probes are the rock stars of the PECT world. They have multiple coils arranged in a grid, giving them the ability to create a detailed image of the material being tested. This makes them the go-to choice for detecting and characterizing defects.

Each type of probe has its own strengths and weaknesses, so the best choice for your inspection will depend on the specific application.

Pulsed Eddy Current Testing: A Powerful Tool for Detecting Corrosion Under Insulation

Corrosion under insulation (CUI) is a sneaky villain that can lurk beneath the protective layers of your assets, causing unseen damage that can compromise their integrity. Enter pulsed eddy current testing (PECT) – your trusty ally in the fight against this hidden enemy.

PECT is like a superhero with a superpower to see through insulation and detect corrosion. It sends out electromagnetic pulses that interact with the material underneath, and any changes in the signal caused by corrosion or other defects are like a fingerprint that PECT can identify.

This non-destructive testing technique is particularly potent in detecting CUI in piping and vessels. It can penetrate through thick layers of insulation without any fuss, giving you a clear picture of what’s going on beneath the surface. PECT can even tell you the size, shape, and severity of the corrosion, helping you make informed decisions about repairs or replacements.

So, if you suspect CUI is making a mess of your assets, don’t hesitate to call on the formidable PECT. With its ability to detect this sneaky corrosion, PECT is your secret weapon for ensuring the safety and longevity of your valuable equipment.

The Synergy of PECT and Other NDT Techniques

Like detectives on a thrilling investigation, different NDT methods work together to reveal the hidden secrets of your assets. One such dynamic duo is Pulsed Eddy Current Testing (PECT) and Ultrasonic Testing (UT).

Imagine PECT as the savvy tech whiz, scanning through materials with electromagnetic pulses. Its superpower? Detecting sneaky corrosion under insulation (CUI), a sneaky enemy lurking in the shadows. But PECT has its limitations, like that cool hacker who can’t see through solid walls.

Enter UT, the ultrasonic superhero with its sonic waves that bounce off hidden flaws like a game of sonar. Together, these two form an unstoppable team, covering each other’s blind spots.

For instance, PECT might find a possible CUI spot, but it needs UT’s eagle-eye vision to confirm its size and depth. It’s like Batman and Robin, with PECT’s detective skills and UT’s crime-fighting gadgets.

So, if you’re looking for a comprehensive inspection that leaves no stone unturned, don’t settle for just one NDT method. Embrace the power of PECT and UT’s harmonious blend. Together, they’ll ensure your assets stay healthy and safe, like a well-tuned symphony of non-destructive detective work.
