Pipeline inline inspection tools
The core MFL tool fleet: more than 20 specifications covering 159–1,422 mm pipe, multi-calibre adaptive technology for variable-diameter lines, and 60+ hour continuous runs.
These are the inspection pigs at the centre of the MFL line. The published core advantage is deformation capacity: conventional inspection equipment typically manages a deformation amount of 15% OD or even smaller, which forces operators to strictly match a tool to each pipe diameter. This fleet attacks that constraint two ways — with more than 20 specifications of testing equipment for full diameter coverage from 159 mm to 1,422 mm, and with multi-calibre adaptive pipeline internal testing technology that performs internal inspection on large variable-diameter pipelines with one tool concept. The product description cites a deformation capacity of up to 40% for the adaptive approach, significantly expanding the range of detectable pipelines; the specification table records the straight-pipe deformation ability at 20% OD or less for this tool configuration.
The operating envelope is published in full: pressure range 0–10 MPa; working temperature from -10 to 80 degrees C; bend passage where the elbow curvature radius is 1.5D or greater; continuous working time of more than 60 hours; and a detection threshold that locates features at +/-0.1 m from the nearest circumferential weld and +/-5 degrees in the circumferential direction — the referencing that makes a dig sheet actionable.
Buyers speccing a first survey should read this alongside the MFL inline inspection service (the same technology delivered as a service) and the MFL testing guide.

What to confirm for your project
- Send your line list (diameters, wall thicknesses, bend radii, valve types) — tool selection is per-line engineering, not a catalogue pick.
- Variable-diameter lines are the adaptive technology's home ground; say so in the brief if your line changes calibre between stations.
- Ask about minimum order requirements and lead time for your proposed configuration or survey.
Buyer questions
What pipe sizes do the tools cover?
159 mm to 1,422 mm, across more than 20 specifications of testing equipment for full diameter coverage.
