X-ray Remote Device for Circumferential Exposure of Large-Diameter Conduit

For the large conduits (≥DN720) in centralized heating or water supply project, circumferential exposure is always applied in nondestructive testing of welding line. But when the conduit is longer than X-ray machine cable, the inspector must go into the conduit to operate the device. Under this condition, the high concentration X-rays in the conduit are harmful to the operator. If the control cable is lengthened, it will bring inconvenience to the work and X-rays will be attenuated. The remote control device installed in X-ray machine can solve the problem of safe and short cable operation for large conduit circumferential exposure.
