X-ray pipeline crawler

Engineered for long-distance oil & gas pipelines, district-heating networks, fresh-water mains and chemical lines, the LX-PC Series Magnetic-Positioning X-Ray Pipeline Crawler merges a high-energy X-ray source, dual-channel magnetic guidance and a rugged wheel-drive chassis into one compact unit. Inside the pipe it delivers a full 360 ° non-destructive test (NDT) in a single pass, pinpointing slag inclusions, lack of fusion, porosity and corrosion — so your pipeline stays leak-free.

What Sets LX-PC Apart

Typical Use Cases

• Mainline oil/gas weld inspection at compressor & valve stations

• Annual safety audits for buried district-heating or potable-water grids

• Post-lay surveys of subsea/shore crossing pipelines

• Turnaround QA/QC in petrochemical plants

Video positioning X-ray pipeline crawlers are generally composed of the following components:

• Crawler system: Including programmable controller, motor driver, motor, wheeled mobile system, etc., to control the crawler to move forward and backward in various pipelines according to instructions.

• X-ray source: Including high-voltage package, and X-ray tube, to generate X-rays, pass through the pipeline, and check the internal quality of the pipeline.

• Camera part: the position of the weld is determined by the camera;

• Video control system: Control the forward, backward, and exposure of the crawler.

• Battery: Provides necessary energy for the crawler, X-ray source, and magnetic receiver.

Depending on the purpose, this type of crawler can be used for pipe diameters of 159 mm-273 mm, 219 mm-500 mm, 375 mm-800 mm, and 500 mm-1400 mm.

The crawler adopts a DC motor drive system with large driving torque and soft start speed regulation to extend the motor life and ensure positioning accuracy; stable high-voltage output to ensure consistent film blackness; and has protection functions such as automatic retraction when encountering water, obstacles, Undervoltage, overcurrent, undercurrent, and overtemperature, ensuring long-term stable and normal operation of the equipment and improving detection efficiency.
