6:CR1 Pipeline Crawler

JME’s 6:CR1 pipeline crawler is specifically designed for non-destructive testing (NDT) of circumferential butt welds in tubular installations such as oil and gas transmission pipelines.

The JME 6:CR1 Pipeline Crawler is extremely compact and lightweight. It enables the operator to produce internal panoramic single wall single image (SWSI) radiographs. This is a versatile system and will operate in pipleines down to 5.3” (135mm) and up to a maximum of 18” in diameter.

The JME 6:CR1 crawler is powered by high-efficiency rechargeable sealed lead acid batteries. 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 6:CR1 crawler features anti-runaway circuitry along with optional audio/visual alarm unit and purpose built latching recovery vehicle.

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