GENERAL NDT

Quality is the new currency in NDT. The world if full of examples where poor quality and cutting corners caused loss of life, and billions in damages.
Radiography is a nondestructive test method that utilizes electromagnetic energy (radiation) from X-rays or gamma rays in order to detect both surface and internal discontinuities. Radiography shadow shots can be used to inspect process piping, pressure vessels and valves, providing an easily viewed and permanent record of the component that has been inspected. 4A INSPECTION has the ability to utilize either Computed or traditional film radiography techniques as per client specification.
  • For new fabrication weld inspection
  • Efficient inspection of large volumes of components
  • Code compliant inspection (ASME Section V for pressure vessels, ASME B31.1 and B31.3 for piping, API 1104 for pipelines, and others)
  • For In-service weld and material inspection. Often, we determine the extent of internal and/or external corrosion/erosion in process piping, pressure vessels and valves
  • For most metal and non-metal materials
  • Access to both sides of the test material is required
  • Physical space is required
  • Large areas adjacent to the component tested must be cleared from persons or items that may be affected by radiation.
  • Environmental conditions may compromise film quality; low temperatures may slow down production
  • Highly reproducible
  • Images on films or digitized
  • Data is stored for future comparison or audits
  • Field ready
  • Systems are portable and battery powered
  • Light enough to easily take onto scaffolding
  • Powerful setup tools to aid technicians in the field
Without Integrity there is no trust. Our commitment is to never compromise the reputation & trust we’ve worked so hard to develop.
Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used.
A crack that is a thousandths of an inch wide, can cause the failure of a massive pressure vessel. Being precise, and looking for the smallest defects is what NDT is all about.
Magnetic particle inspection (MT) is a non-destructive testing method used to detect surface and slightly subsurface flaws in ferromagnetic materials (such as carbon steel). It is used routinely to inspect welds, piping, pressure vessels and structural steel components.
We are not afraid to work hard, and do what it takes to do the job right.
Liquid Penetrant Testing (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. PT is a non-destructive examination method used to locate surface breaking discontinuities in non-porous materials (metals, plastics, or ceramics). This method may be applied to ferrous and non-ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability.

Portable Hardness Testing

Simply stated, hardness is the resistance of a material to permanent indentation. It is important to recognize that hardness is an empirical test and therefore hardness is not a material property.
