Overview

Product overview

Spyne is a surface eddy current array (ECA) screening tool for pipelines, tanks, pressure vessels and other critical components. Interchangeable flexible PCB probes adapt it to ferrous or non-ferrous materials, supporting detection of surface-breaking cracks, subsurface defects and other material-specific indications. Its adjustable configuration accommodates external pipe diameters from 150 mm (6 in) to flat surfaces.

The flexible ECA probe collects inspection data while a spring-loaded wheel records axial position and a gyroscopic device tracks circumferential position. Raster scanning combines these measurements into a single data file covering the pipe exterior, with nominal single-pass coverage of 200 mm (8 in). The system supports inspection through non-conductive coatings and paints with liftoff monitoring and automatic correction, up to the stated 3 mm (0.12 in) tolerance.

Typical work includes pipeline stress corrosion cracking assessment, hard-spot detection, seam-weld indication screening and early-stage chloride stress corrosion cracking detection in stainless steel. Ferrous and non-ferrous probe variants have distinct element arrangements, coil dimensions and flaw-detection specifications. Spyne is specified for surface temperatures up to 150ºC (302ºF); the higher emulsion-pipeline operating temperature discussed on the page is application context, not a higher probe rating.

Magnifi displays encoded results as C-scans and automatically highlights indications using an adjustable signal threshold. SIMS PRO ECA can import the data for mapping, standardized reporting, repair tracking and traceability, with depth-sizing reports supported by complementary techniques. Pre-calibration reduces setup work to a calibration check, while optional magnetic wheels assist scanning along pipe sides and undersides.

Key Features

Key capabilities

Dual-axis encoding

Gyroscopic circumferential encoding and a spring-loaded axial encoder locate indications around and along the pipe.

Flexible interchangeable probes

Spring-loaded flexible ECA probes can be exchanged for ferrous and non-ferrous inspection applications.

Wide single-pass coverage

Nominal 200 mm (8 in) coverage supports rapid screening of large surfaces.

Raster and comb scanning

Full raster and comb scan capability supports recording the complete pipe exterior in a single data file.

Coating tolerance

Non-conductive coatings and paints can remain in place within the specified liftoff tolerance, with monitoring and automatic correction.

High-temperature operation

Spyne supports use on surfaces up to 150ºC (302ºF).

Assisted detection

Magnifi automatically highlights C-scan indications according to an adjustable detection threshold.

Integrated reporting

SIMS PRO ECA supports inspection-data mapping, standardized reports and traceability.

Ergonomic controls

Handles incorporate acquisition control buttons, and the embedded spring-loaded encoder is detachable.

Pre-calibrated setup

The pre-calibrated system requires only a calibration check before inspection.
