The JME 24″ X-ray Pipeline Crawler is specifically designed for non-destructive examinations of circumferential butt welds in tubular installations such as oil and gas transmission pipelines.


The JME MAXI 24″ Pipeline Crawler is robust and suitable for use in a wide range of challenging environmental conditions.  It enables the operator to produce internal panoramic Single Wall Single Image (SWS) radiographs. This is a versatile system and will operate in pipelines down to 24″ (135 mm) and up to a maximum of 72″ in diameter.

The JME MAXI crawler is powered by high-efficiency rechargeable sealed lead acid batteries.  With JME’s 24″ MAXI crawler, JME have incorporated the ability to use the system in conjunction with a generator to top-up the batteries during operation.  The crawler can be commanded either using JME’s magnetic control system (Magnetope) or alternatively with a conventional isotope control system.  These systems can be used to control travel, park and exposure modes from outside the pipeline.

Safety and asset protection are always a consideration.  The JME MAXI  Crawler features anti-runaway circuitry along with optional audio/visual alarm unit.

JME’s entire pipeline crawler range is constructed using high quality material ensuring corrosion resistance, easy maintenance and an extended service life.  The systems feature a modular design allowing simple and easy maintenance in the field.  All electronic circuitry utilize military specification components ensuring reliability in harsh environments.
