What we do:

RT uses penetrating gamma and X-ray radiation that creates an image of the inside of a surface. For example, the wall of a steel pipe. The X-rays are generated by an electronic generator or an isotope source of radioactive material. X-ray film or a digital detector (CR/DR) is placed behind the part, and when exposed to the X-rays traveling through the part, creates a visible image similar to a medical X-ray. Common indications found are voids, cracks, internal corrosion, stress corrosion cracking, and defective welds.

MT is completed by inducing a magnetic field in a ferromagnetic material and covering the excited part with iron particles. The particles may be dry or suspended in a fluid. Defects in the surface like voids and cracks cause disruptions in the magnetic field lines of the part and force the iron particles to concentrate at the indications due to magnetic flux leakage. MT makes it easy to see cracks and other defects in the surface of a part that would normally be too small to see by the eye alone. Common indications found with MT include cracks, pits, voids, and sometimes even indications below the surface.

PT is one of the oldest methods of finding indications in parts which are not visible by the eye.  This widely used inspection method used to check 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.

UT is similar to an ultrasound used in medicine. It uses high frequency sound waves that travel through material to create a signal or image showing the internal structure of the material. The simplest form of UT is thickness measurement where the thickness of material can be measured to evaluate the remaining life of a pipe or tank. More complex methods, including pulse echo, time-of-flight diffraction, and shear wave, measure the reflected sound waves returning to the probe and, using complex calculations, create 3D images of the internal structure of a part.

UT is useful for both metallic and composite parts, making it a very important disciplines to find cracks, voids, delamination, and other indications in modern construction for aerospace, wind power, and automotive inspection.

VT is based on the inspection for flaws that are visible to the naked eye and is the most commonly used NDT method across all industries. It allows for a feasible and fast control of quality at every step of the fabrication or maintenance process.

Visual Testing (VT) is used to detect visible flaws such as deformation, welding defects and corrosion. Many tools can be used during the inspection such as a ruler, gauges, flexible borescopes, videoscopes, etc

What our clients say:

Penn Testing has always been a great service. They are responsive, professional, and their expertise have helped Bridesburg become a leader in the Navy castings business. Our company has benefited from using their services. They are someone you can always depend on.

Gregory B., Bridesburg Foundry

Penn Testing has been a very reliable resource for our pressure vessel x-ray and PMI needs for the past years. Their expertise, along with their quick turnaround times (sometimes while I wait at their facility) has been instrumental with keeping our projects on schedule.

Their knowledgeable staff is very helpful when providing information on x-ray results and their communication concerning project completion, issues with specimens, and overall customer service is second to none. They’ve always gone above and beyond to meet our testing and QC needs.
