Trecoil S.r.l. - Inspection

Inspection tools

We provide different type of inspection tools. Each of them performs a specific task.
You can read more details on how they work into their data sheets.

Single-Channel
Caliper Pig

Our Single-Channel Caliper Pig detects pipeline's diameter reductions and variations such as dents, ovalities, circumferential welding and wall thickness variations, which reduce the internal diameter of the pipe.

Multi-Channel
Caliper Pig

The Multi-Channel Caliper Pig implements the ability of sizing and positioning the differentiation longitudinal and circumferential of the different types of defects.

Magnetic Flux
Leakage

The MFL inspection activity detects metal losses, pitting (internal and external) and cracks. Also it provides inertial mapping (X, Y, Z) of the pipeline and measurement of the voltages induced by the movement of the ground.

Ultrasonic
Tool

The UT inspection activity detects metal losses, pitting and cracks. Also it provides a complete analysis of the status of pipeline and measurement of the sonic response generated by the tool movement and the pipe-wall.

Measurements

Caliper Pig
Diameter reductions and variations

Thanks to the long standing experience and progressive improvements, the Caliper Pig's purpose-adapted structure meets extreme conditions for operation in pipelines. The Caliper Pig is able to pass extreme deformation (up to 25%) and, thanks to the high sensitivity of the gauging system and the large number of sensing fingers, even the smallest reductions and variations can be detected.

Dents affect the safe operation of a pipeline as they restrict the flow of the transported medium and tend to induce spot-like formations of sedimentation, turbulence, erosion, corrosion and hydrates. The pipeline's service life is shortened further by localized excessive mechanical stress.
