Abstract: Disclosed are joints and methods for forming joints of nonmetallic components such as piping components made from a nonmetallic composite material. The components are joined by an adhesive containing an x-ray absorbing additive for providing a contrasting signal in x-ray inspection of the joint. The joints can be nondestructively tested by positioning the joints relative to an x-ray source and an x-ray detector. The joints and the adhesive therein are then exposed to x-ray radiation from the source of x-ray radiation. The x-ray radiation, having passed from the x-ray source to the x-ray detector, is detected over an area and an x-ray image of the x-ray radiation detected is created. The x-ray image is then read to identify defects in the joint.
