Internal insight
Radiography
Radiography detects features in a component or assembly that differ in thickness or physical density from the surrounding material. Large differences are more readily detected than small ones.
Radiography can detect features that have appreciable thickness in a direction parallel to the radiation beam. The ability to detect planar discontinuities such as cracks therefore depends on proper orientation of the test piece.
Discontinuities such as voids and inclusions have measurable thickness in all directions and can be detected when they are not too small in relation to the section thickness. In general, features exhibiting a difference of 1% or more in absorption compared with the surrounding material can be detected.
Shop and field applications
A complete line of radiographic services
We offer radiographic services for both shop and field applications.
- Certified and qualified professional radiographers work within strict safety protocols to deliver high-quality radiographs and determine whether an anomaly is a defect or is acceptable under code requirements.
- Each project is analyzed so resources can be distributed effectively around client specifications and production schedules.
- We specialize in gamma-ray inspection for external evaluation of structural process piping and pipeline construction. High-quality equipment and experienced personnel support first-rate performance on every project.
Our in-house training programs support the highest levels of radiation-safety compliance and consistently high-quality film images.
We also offer digital radiography for customers seeking a transition to this technology.
