Ultrasonic Inspection of Oil & Gas Pipelines

cable for ultrasonic inspection of pipelines in Alaska built by Multi/CableBackground:

A manufacturer of testing equipment for the oil & gas industry needed a cable for ultrasonic inspection of pipelines in Alaska to test for corrosion and cracks in the pipeline.


The cable had to connect many different types of instrumentation to a central recording station for power and data transmission.

The Multi/Cable Solution:

The finished cable built by Multi/Cable had an inner core of sixteen 24 AWG conductors with a shield and PVC jacket.

  • The intermediate layer has 9 twisted shielded pairs of 20 AWG stranded copper with an overall PVC jacket.
  • The outer layer has 4 individually jacketed pairs, 8 triaxial cables for cameras, one tube for the ultrasonic testing liquid, and two twisted pairs with a fiberglass and stainless steel braid as well as a PVC jacket.

All this went under a blue polyurethane jacket for a finished cable under one and a half inches in diameter.
