Описание (английский):

ISO 25902-1:2009 specifies a method for the eddy-current examination for detecting flaws in titanium seamless tubes and welded tubes. Titanium tubes are now used as steam surface condensers in steam-power plants, anatomic-power plants and desalination plants. Therefore, the quality of titanium tubes is very important and this is why the eddy-current inspection method was established. This method also applies to titanium alloy tubes.

Overview

ISO 25902-1:2009 defines an eddy‑current non‑destructive testing (NDT) method for detecting flaws in titanium seamless and welded tubes (including titanium alloys). It targets quality assurance for titanium tubes used in critical heat‑exchange applications - the standard text specifically cites use in steam surface condensers for steam‑power plants, “anatomic‑power plants” (as printed in the document) and desalination plants. The standard sets requirements for equipment, reference pieces, test procedures, acceptance criteria and reporting.

Key topics and requirements

Applicable dimensions: tubes with outside diameter 10–150 mm and wall thickness 0.3–10 mm are covered; the standard highlights that detection sensitivity varies with outside diameter and uses a 38.1 mm division when specifying reference standards.

Test method: encircling (concentric) test coil of self‑comparison type; eddy‑current frequencies from 1 kHz to 512 kHz - select a frequency that detects the chosen reference standard.

Reference standards: two classes - rectangular groove (N) and drilled hole (D). Materials and surface condition of the reference piece must match the tubes under test. Dimensions and tolerances for grooves/holes are specified and used for instrument sensitivity setting.

Apparatus & verification: eddy‑current instrument (oscillator, signal processor, display/recorder), tube feed device, automatic alarm/recorder. Performance verification and periodic checks are required (see ISO 15548‑1 for instrument verification).

Sensitivity & adjustment: instrument sensitivity adjusted so the reference standard gives about 50% of the recorder scale; sensitivity confirmation at least every 4 hours, after interruptions or at end of operations.

Acceptance criteria: tube is accepted if no signals equal to or greater than the reference‑standard signal are detected, except for benign signals from straightening marks, ring marks, rough surface, dents, or similar harmless features.

Reporting: date, inspector, tube grade, dimensions, equipment, reference standards used, test coil and frequency, detection conditions (feed speed, sensitivity, phase) and results.

Applications and users
