1.INTRODUCTION

The DPTXQ-III X-ray Pipeline Crawler System is designed for non-destructive test of circumferential butt welds in pipelines such as gas and oil transmission lines. Thanks to its internal circumferential X-ray tube, it can test single circumferential butt welds with just one exposure. Therefore compares to the common outboard testing in the past, the work efficiency increased dramatically, as well as lowered workload of operations.

The main features of the system including compact design, low weight, ease of operation, reliable and wide range of applications.

2.MAIN TECHNICAL SPECIFICATIONS

•Pipeline diameter range: 600-820mm

•Thickness of the pipeline: 5-28mm

•Max angle of climb: 38°

•Travel speed: 15m/min

•Travel distance: 0-1000m (Return)

•Weight: 200Kg

•Power source: DC batteries (120V)

3.SYSTEM COMPONENTS

The Pipeline Crawler System consists of the crawler, magnetic positioning system, X-ray generator, DC battery and recharger, radiation alarm.

•Crawler: To move the system inside the pipeline.

•Magnetic positioning system: Including emitter and receiver, to direct the crawler moving to the precise welding points.

•X-ray generator: Generates X-ray which penetrate through the testing area, to acquire an X-ray image.

•DC power: A 120V DC battery, to power the whole system.

•Recharger: To recharge the battery.

•Radiation alarm: Prompting when the crawler is in exposure mode for safety.
